Users who experience this error have reported that other Microsoft applications, such as Office apps, Skype, Edge, and other programs, also crash as a result. They may receive the following error message at the time:

It's important for users to address this error promptly, as it can disrupt productivity and collaboration for teams using Teams and other Microsoft applications. Below we provide a detailed guide on how to fix Teams.exe - Application error, although we recommend first running a PC repair tool [d1], which can perform many of the manual steps automatically for you.

Solution 1. Update Windows

If you have been neglecting Windows updates, you should definitely install all available ones, as Microsoft fixes bugs continuously - they can only be applied via the patching process.

• Type Updates in Windows search and press Enter.
• Click Check for updates and wait till Windows downloads the necessary files.
• Install all the optional updates if they are available.
• Restart your PC.

Solution 2. Fix system files

Running commands via an elevated Command Prompt can help you fix any issues related to system file corruption.

• Type cmd in Windows search.
• Right-click on Command Prompt and pick Run as administrator.
• When User Account Control asks you whether you want to allow changes, click Yes.
• Paste the following command and press Enter:
  sfc /scannow
• Once that is done, use the following commands, pressing Enter each time:
  dism /online /cleanup-image /scanhealth
  dism /online /cleanup-image /checkhealth
  dism /online /cleanup-image /restorehealth
• Reboot your computer.

Solution 3. Try Clean boot

To resolve software conflicts, use Clean boot. Here's how:

• Type msconfig in Windows search and press Enter.
• Go to the Services tab.
• Check the Hide all Microsoft services box and pick Disable all.
• Go to the Startup tab and select Open Task Manager.
• In the Task Manager, right-click on every entry and select Disable, then close the Task Manager
• Go to the Boot tab, tick Safe Boot, then click Apply and OK.

To identify the app causing conflicts, boot into Clean Boot Environment and systematically turn items on/off. This process may be slow if done one at a time, so to reduce this diagnostic time, try marking half of the programs and repeating until you locate the source of trouble. This method lets you quickly remove any offending program leading to your problem.

Solution 4. Clear cache

• Make sure Teams is not running (close from the system tray or Task Manager).
• Press Win + R on your keyboard to open the Run dialog.
• Type AppData and press Enter or click OK.
• Go to the following location:
  C:\Users\User\AppData\Local\Microsoft
• Delete all the files and folders located in the Teams folder.
• Start the app again.

Solution 5. Try System Restore

• Type in Create a Restore Point in Windows search and hit Enter.
• Click System Restore.
• Pick Choose a different restore point (if available) and click Next.
• Mark the Show more restore points checkbox.
• Choose a time when the issue was not present.
• Click Next and reboot the computer as required.

Solution 6. Reinstall the app

• Click Start and go to Settings.
• Go to the Apps section.
• Scroll down to find Microsoft Teams.
• Click Uninstall and then confirm with Uninstall.
• Follow on-screen instructions to remove the app.
• Reboot your system and reinstall Teams.
