Support knowledge base

IT support questions, answered.

Start with safe, practical checks for computers, Microsoft 365, printing, backup, security, internet and Wi-Fi.

Before you begin

Use the lowest-risk fix first.

These answers are general guidance. Your company’s policies, managed settings and equipment instructions take priority. Save your work before restarting anything, and do not factory-reset business equipment, disable security tools or share a password or verification code.

Contact support

Stop and contact support

Do not keep troubleshooting when security or data may be at risk.

  • You entered a password after clicking a suspicious link.
  • You received an approval prompt you did not initiate.
  • Files are unexpectedly encrypted, renamed or replaced with ransom notes.
  • A business device containing company data is lost or stolen.
  • Equipment is unusually hot, smells burnt, sparks or shows physical damage.

If there may be an active compromise, disconnect the affected computer from Wi-Fi or its network cable without shutting it down, then call from another device.

01 · First checks

Start here

A few observations can solve the issue—or make the support request much faster.

What should I check first when something stops working?
  1. Save any work that is still available.
  2. Read and photograph the complete error message.
  3. Check power, cables, Wi-Fi and whether the correct account or device is selected.
  4. Ask whether another person or device has the same problem.
  5. Close and reopen only the affected application. If that does not help, restart the computer.

Change one thing at a time so you know what helped.

Is it safe to restart my computer?

Usually, yes. Save your work, close applications and choose Restart from the operating system. Do not hold the power button unless the computer is completely unresponsive, and never interrupt a screen that says an update is being installed. Contact support before restarting a server, firewall, network switch, shared storage device or other business infrastructure.

How can I tell whether the problem is my device or the whole office?

Check the same service from a second device and ask one coworker whether it works for them. If only one device is affected, focus on that device, its connection and its sign-in. If several people or unrelated devices are affected, stop restarting individual computers and report a shared outage.

What information should I include in a support request?

Send your request to helpdesk@grapecomm.net. Include your name and business, the device or room, what you were trying to do, the exact error, when it started, what changed beforehand, who is affected and what you already tried. A photo or screenshot is useful when it does not contain confidential information. Never include passwords, full payment-card information or one-time verification codes.

What troubleshooting steps should I avoid on a business system?

Do not factory-reset equipment, move cables in a network rack, remove managed accounts, uninstall security software, edit the registry, delete system folders or install “driver updater,” “PC cleaner” or remote-control software from an advertisement. These actions can remove configuration, weaken security or make recovery harder.

02 · Everyday devices

Computers & applications

Safe first steps for Windows computers, business applications and common accessories.

Why is my computer suddenly slow?
  1. Restart the computer if it has not been restarted recently.
  2. Close unused browser tabs and applications.
  3. Check whether a large download, update, backup or cloud sync is running.
  4. Confirm that the main drive is not nearly full.

If the slowdown started after a pop-up, download or security alert—or continues after a restart—contact support. Avoid installing cleanup utilities.

An application is frozen. What should I do?

Wait a minute if the application may be saving or processing a large file. Try closing the application normally. If Windows identifies it as not responding, use Task Manager only to end that application, then reopen it and check whether your work was recovered. Restart the computer if multiple applications are frozen. Repeated freezing usually needs investigation rather than repeated forced shutdowns.

An application will not open. How can I troubleshoot it?
  1. Make sure it is not already open behind another window or on a second display.
  2. Restart the computer.
  3. Confirm that other applications and websites work.
  4. Record any error message and whether the problem affects other users.

Do not uninstall or reinstall a licensed or company-managed application unless support confirms the license, data and settings are protected.

My screen is black or the computer will not start. What can I check?

Confirm the computer and display have power, the display is on, and the correct input is selected. Reseat only the external power and display cables you can clearly identify. If using a laptop dock, disconnect and reconnect the laptop once. Stop if you hear unusual beeps, see physical damage or smell heat. Do not repeatedly power-cycle a device that may have a hardware failure.

My computer says storage is full. Can I delete files?

Empty the Recycle Bin only after reviewing it, remove unneeded downloads you recognize and move approved files to the company’s designated storage location. Do not delete Windows, Program Files, application-data folders or unfamiliar large files. A nearly full drive can interrupt updates, email and cloud sync, so contact support if basic cleanup does not create adequate space.

My microphone, camera or speakers are not working.

Check for a physical mute or camera-privacy switch. In the application, select the intended microphone, speaker and camera rather than “Default” if multiple devices are listed. Unplug and reconnect a USB headset or dock, then close and reopen the application. If the device works in one application but not another, the issue is usually that application’s selection or privacy permission.

Why is my second monitor not detected?

Confirm the monitor has power and is set to the input matching its cable. Reseat the cable at both ends and reconnect the laptop dock if one is used. In Windows, open Display settings and choose Detect. If another known-good cable or dock port is available, test one change at a time. Avoid forcing damaged connectors.

03 · Cloud productivity

Microsoft 365, Outlook, Teams & OneDrive

Common sign-in, email, meeting and file-sync issues.

Microsoft 365 keeps asking me to sign in. What should I do?

Confirm the sign-in window shows your organization’s expected domain and that the request appeared after you opened a Microsoft application—not from an email link or unexpected browser pop-up. Close all Office applications, reopen one and sign in once with your work account. If prompts continue, record the error and contact support; repeatedly entering credentials into unfamiliar prompts is not a safe fix.

I forgot my Microsoft 365 password or my account is locked.

Use only your organization’s approved password-reset process or contact its administrator. Do not ask a coworker to receive a verification code for you, and do not reuse an old or personal password. If the lockout was unexpected, report it so recent sign-ins and account security can be reviewed.

Outlook is not sending or receiving email.
  1. Check whether you can open another website.
  2. Look for “Working Offline,” “Disconnected” or a sign-in warning in Outlook.
  3. Open Microsoft 365 webmail in a trusted browser to see whether new mail is there.
  4. Check the Outbox for a very large or stuck message.
  5. Restart Outlook, then restart the computer if needed.

If webmail also fails or several people are affected, report the shared issue.

Outlook will not open or keeps crashing.

Restart the computer and try Outlook again. Use webmail as a temporary option if your organization permits it. Note whether the failure began after an add-in, update or unusual attachment. Do not delete your Outlook profile or local data file without support; doing so can remove cached or locally stored information.

Why am I not receiving a message I expected?

Search by the sender’s address and subject, then check Junk Email, Deleted Items, focused/other inbox tabs and any rules or quarantine notices your organization provides. Ask the sender to confirm the exact address used and whether they received a delivery error. Do not ask the sender to resend sensitive information through a personal account as a workaround.

Outlook says my mailbox is full.

Empty Deleted Items and Junk Email after reviewing them, then sort large folders by size and remove or archive only messages allowed by company policy. Saving attachments elsewhere does not remove the email unless the message itself is deleted. Contact support before deleting business records or changing retention settings.

My camera or microphone does not work in Teams.

Before the meeting, open Teams device settings and select the intended camera, microphone and speaker. Close other applications that may be using the camera, check physical mute/privacy controls and reconnect a USB headset or dock. Use Teams’ test-call feature when available. If the browser version is in use, confirm the browser has permission to use the camera and microphone.

OneDrive says it is not syncing.

Select the OneDrive cloud icon and read the reported issue. Confirm you are signed into the correct work account, the computer is online and the file is not open elsewhere. File names, path length, unavailable permissions or lack of storage can block sync. Pause before deleting, moving or renaming a large set of files—unsynced changes may be the only current copy.

A Microsoft 365 file is missing. Where should I look?

Search OneDrive, SharePoint or Teams from the web, check Recent files and the appropriate recycle bin, and confirm you are signed into the correct organization. Ask whether the file was moved or renamed. If it may have been deleted or overwritten, stop creating replacement files with the same name and contact support promptly so recovery options can be checked.

04 · Office equipment

Printing & scanning

Resolve the most common printer and scanner issues without changing network settings.

The printer says “offline.” What should I check?
  1. Make sure the printer is powered on and shows no paper, toner, jam or door error.
  2. Confirm your computer is connected to the normal business network, not a guest network or phone hotspot.
  3. Verify you selected the intended printer.
  4. Restart the printer once using its power control, then restart the computer.

If several people cannot print, report it as a shared printer or network issue.

A print job is stuck in the queue.

Open the printer queue and cancel the failed job. Wait for it to disappear before sending the document again. If it remains stuck, restart the printer and your computer. Do not repeatedly click Print; duplicate jobs may all release later. A queue that will not clear may require support to restart the managed print service.

I cannot find the office printer.

Confirm you are in the office and connected to the correct business network or approved VPN. Check whether coworkers can still see the printer. If the printer was recently replaced, moved or renamed, use the organization’s approved installation method or ask support to add it. Avoid downloading printer drivers from advertisements or unofficial websites.

My document prints on the wrong printer, paper size or tray.

In the application’s Print window, choose the intended printer and review paper size, orientation, color, duplex and tray before printing. Application settings can override Windows defaults. If one document is affected, test a simple one-page file; if every document is affected, the printer’s defaults or driver may need correction.

Print quality is poor or pages are streaked.

Check the printer display for low toner or ink, confirm the paper is dry and appropriate for the printer, and use the printer’s built-in quality or cleaning function once. Do not touch imaging drums or use household cleaners inside the device. Repeated lines, smears or color problems usually require supplies or service.

Scanning or scan-to-email is not working.

First determine whether scanning fails from the computer, the printer’s front panel or only when sending email. Confirm the destination and file size, and check for a message on the printer. Scan-to-email can fail even while printing works because it relies on separate account and mail settings. Record the exact error rather than changing those settings yourself.

05 · Connectivity

Internet, networks & better Wi-Fi

Separate a device problem from a Wi-Fi coverage problem or a broader internet outage.

My device says it is connected to Wi-Fi but there is no internet.

Turn Wi-Fi off and back on, confirm you joined the expected network and test two unrelated websites. Then test from another device on the same Wi-Fi. If the second device works, restart the affected device. If nothing works, report a possible network or provider outage. A Wi-Fi connection only confirms a link to the local network; it does not guarantee internet service.

Wi-Fi works for everyone except me.

Confirm airplane mode is off and Wi-Fi is on, disconnect any phone hotspot or unapproved VPN, and verify the exact network name. Turn Wi-Fi off and on, then restart the device. If your organization permits forgetting the saved network, you may reconnect using the approved credentials; otherwise contact support to avoid removing managed settings.

The internet appears down for the entire office.

Check whether wired computers, Wi-Fi devices and business phones are all affected, and note the time the outage began. Look for obvious power loss or visible equipment alarms without moving cables. Call support or the designated provider contact. Do not factory-reset or randomly power-cycle the modem, firewall, switches or access points; a managed network may require a specific restart order and configuration.

Why is Wi-Fi slow even though I have a strong signal?

Signal bars measure the connection to a nearby access point, not the speed of the internet service or the health of the whole network. Test another device in the same location and compare a wired connection if available. Large downloads, cloud backups, video meetings, interference, overloaded equipment or the internet provider can all reduce performance. Record the location, time and affected applications so the cause can be measured.

Why does Wi-Fi drop in one room or part of the building?

Walls, metal, equipment, distance and interference can weaken or distort wireless coverage. Note exactly where the connection changes and whether multiple devices behave the same way. Moving the device into the open can help confirm a coverage problem, but a lasting fix may require adjusting or adding professionally placed access points after a coverage review.

Will a Wi-Fi extender fix weak coverage?

Sometimes, but an extender can also repeat an already weak connection, reduce usable capacity or create roaming problems. A business environment is usually better served by correctly located, managed access points connected to the network. Before adding equipment, identify whether the problem is coverage, interference, capacity, cabling or the internet service itself.

What is the best way to improve business Wi-Fi?

Start with the building layout, user count, device types, critical applications, guest needs and current cabling. Measure coverage and performance during real operating conditions. A good design places access points for both coverage and capacity, separates appropriate traffic, and coordinates the wireless system with switching, firewall and internet service. Buying a faster router alone does not address every cause.

Should stationary business equipment use Ethernet or Wi-Fi?

When practical, a properly installed wired Ethernet connection is generally the more predictable choice for fixed computers, printers, phones, point-of-sale devices, cameras and other critical equipment. Wi-Fi remains valuable for mobility. Moving suitable devices to wired connections can also preserve wireless capacity for laptops, tablets and phones.

Why should guests use a separate Wi-Fi network?

A properly configured guest network can give visitors internet access without placing them on the same network as business computers, printers and other internal systems. The name and password should be provided through your approved process. Do not share internal Wi-Fi credentials as a quick workaround.

When is it safe to restart network equipment?

Restart only a clearly identified consumer device you are authorized to manage and only when doing so will not interrupt business operations, phones, security or remote access. For managed business networks, contact support first. Never press a recessed Reset button; that commonly erases the configuration rather than performing a normal restart.

06 · Protect the business

Security & suspicious activity

When in doubt, pause. Fast reporting matters more than proving whether something is malicious.

How should I handle a suspicious email or text message?

Do not click links, open attachments, reply or call a number in the message. Verify the request using a known phone number or a new message to a trusted address—not the contact information provided in the suspicious message. Report it through your company’s approved process. Urgency, payment changes and requests for passwords or verification codes deserve extra caution.

I clicked a suspicious link but did not enter anything. What now?

Close the page, do not download or run anything, and contact support with the message and approximate time. Do not clear browser history or delete the message until support says it is no longer needed for review. If a file downloaded or the device began behaving unusually, disconnect it from the network and call from another device.

I entered my password on a suspicious page.

Contact support immediately from another device. Tell them which account was used and whether you entered or approved a verification code. Use only the organization’s trusted password-reset process; changing the password is important, but administrators may also need to revoke active sessions, review sign-ins and check account rules.

I received a sign-in approval or MFA prompt I did not initiate.

Deny the request and report it immediately. Do not approve it to make the notification stop, and never read a verification code to someone who called or messaged you. Repeated prompts can mean someone already knows the password, so the account should be reviewed.

A browser page says my computer has a virus and tells me to call.

Do not call the number, install software or provide payment information. Close the tab or browser. If the page will not close, end the browser through Task Manager or restart the computer. Contact support if anything was downloaded, installed or entered. Legitimate support does not begin with an unsolicited browser alarm demanding an immediate phone call.

My security software displayed an alert.

Leave the alert visible or take a photo, note the time and contact support. Do not disable the protection, restore a quarantined item or add an exclusion unless directed by an authorized administrator. If the alert reports active ransomware, credential theft or repeated detections, disconnect the device from the network.

A company laptop or phone is lost or stolen.

Report it immediately with the device type, assigned user, last known location and approximate time. Do not wait to see whether it turns up. Administrators may be able to lock the device, revoke sessions, protect accounts or preserve records. If theft is involved, follow company guidance about a police report and personal safety.

Files have strange names, will not open or a ransom note appeared.

Disconnect the affected computer from Wi-Fi and its network cable, but do not shut it down, delete files, pay anyone or attach backup drives. Call support from another device. If shared files are affected, tell coworkers to stop using the affected folders until the incident is contained.

07 · Business continuity

Backup & file recovery

Know what is protected before a lost file becomes a larger interruption.

Is OneDrive or another sync service the same as a backup?

Not necessarily. Sync keeps files consistent across locations, which means deletion, corruption or unwanted changes may also synchronize. Some services include version history and recycle bins, but their limits depend on configuration and retention. A backup is a separately managed recovery copy designed around defined business needs. Confirm what your organization actually protects rather than assuming a cloud icon means every file is backed up.

How do I know whether backups are working?

A “completed” message is helpful but not enough by itself. Confirm which devices, cloud services and folders are included; review recent job status and alerts; and perform authorized test restores on a schedule. The organization should know who reviews failures, how long versions are retained and what recovery expectations have been agreed.

I accidentally deleted a file. What should I do?

Stop creating or moving files in the same location. Check the local Recycle Bin and the recycle bin or deleted-items area of the approved cloud service. Note the original name, folder and approximate deletion time. If the file is important or not immediately visible, contact support promptly because recovery windows can be limited.

I saved over the wrong version of a file.

Do not keep editing or repeatedly save the file. If it is stored in OneDrive, SharePoint or another managed service, check the service’s version-history feature. Otherwise contact support with the path, name and approximate time of the unwanted save. Recovery depends on where the file was stored and the backup or retention configuration.

Can I use a USB drive as my business backup?

A USB drive can be one copy, but it is easy to lose, damage, leave connected during an attack or forget to update. Business backup should be planned around the importance and location of the data, appropriate encryption, separate copies, monitoring, retention and tested recovery. Do not connect an unknown or previously compromised drive to a business computer.

Should I restore files myself after malware or ransomware?

No. Restoration should wait until the incident is contained and the recovery source is known to be safe. Reconnecting backups too early can expose them to the same threat or overwrite useful recovery points. Support should coordinate containment, investigation, rebuilding and restoration in the correct order.

08 · Away from the office

Remote work & video meetings

Check the local connection first, then the business access method.

My VPN will not connect.

Confirm ordinary websites work before opening the VPN, check the computer’s date and time, and verify you are using the approved VPN application and work account. Close and reopen the VPN, then restart the computer. Save the exact error. Do not install a different VPN client, change security settings or repeatedly approve unexpected verification prompts.

An application works in the office but not from home.

The application may require the approved VPN, remote desktop, licensing connection or office network. Confirm the business access method is connected before opening the application. If it still fails, note whether other internal resources work. Do not copy company data to a personal email, drive or cloud account as a workaround.

Video meetings sound choppy or keep freezing.

Move closer to the access point or use Ethernet if available, pause nonessential downloads and streaming, and ask others on the same connection to reduce heavy use during the meeting. Turning off outgoing video may stabilize audio temporarily. If the problem happens in one meeting application only, check its device and network settings; if all internet use is affected, troubleshoot the home connection.

How can I improve Wi-Fi in a home office?

Work in the open and closer to the main access point, avoid placing equipment behind televisions, metal or dense walls, and use wired Ethernet where practical. Test at different times to separate coverage from provider congestion. For a lasting improvement, assess the full home layout and existing cabling before adding extenders or changing equipment.

How does Grapevine remote support work?

A Grapevine team member will direct you to the approved remote-support page and tell you what to expect. Start a session only when you initiated or verified the support request. Stay available during the session, close unrelated confidential information and never accept an unsolicited remote-access request.

Getting more help

Some problems need access, testing or a broader plan.

When should I stop troubleshooting and contact support?

Contact support when security or data may be at risk, several users are affected, the same problem returns, you need administrator access, equipment shows a physical fault, or a safe restart did not help. Also stop when the next step would require changing business-wide settings, removing software or guessing at a configuration.

Can this be handled remotely, or does someone need to come on-site?

Account, software, email and many computer issues can often be diagnosed remotely with your permission. Cabling, failed hardware, Wi-Fi coverage, printing hardware and building-wide infrastructure may require an on-site visit. Start with the impact and symptoms; Grapevine can determine the appropriate response.

What if the same issue keeps coming back?

Keep a short record of dates, locations, affected users, screenshots and temporary fixes. A repeating problem may point to capacity, aging hardware, software conflicts, cabling, internet service or configuration—not simply user error. Ask for a root-cause review rather than continuing the same workaround.

Can Grapevine help if we are not an existing customer?

Yes. Tell us about your business, locations, current technology, recurring problems and priorities. We can begin with a discovery conversation and determine whether remote support, an on-site assessment, a focused project or an ongoing IT relationship is the right next step.
