Why do my Teams on Microsoft Teams not work?

Hi @Carlotta,

Thank you for reaching out.

Based on your description, here are some recommended steps you can try to troubleshoot the issue:

1/ Try accessing Teams via the web

Open Microsoft Teams in a browser at: https://teams.cloud.microsoft/or try signing in from another device. This helps determine if the issue is specific to the desktop app.

2/ Sign out and sign back in

Sign out of Microsoft Teams, then fully close the application.

• On Windows: right-click the Teams icon in the taskbar and select Close window
• Reopen Teams and sign back in

3/ Clear the Teams cache

For Windows: 

• If Teams is still running, right-click the Teams icon on the taskbar and select Quit. 
• Press Windows + R to open the Run dialog box. 
• In the Run dialog box, enter the following path and click OK:  

 %userprofile%\appdata\local\Packages\MSTeams_8wekyb3d8bbwe\LocalCache\Microsoft\MSTeams   

• Delete all files and folders in this directory. 
• Restart Teams. 

For macOS: 

• If Teams is still running, right-click the Teams icon in the dock and select Quit, or press Command + Q. 
• Open Finder > go to Applications > Utilities > double-click Terminal. 
• Enter the following commands, pressing Return after each one: 

rm -rf ~/Library/Group Containers/UBF8T346G9.com.microsoft.teams    

rm -rf ~/Library/Containers/com.microsoft.teams2   

• Restart Teams. 

For reference: Clear the Teams client cache - Microsoft Teams | Microsoft Learn

4/ Repair the Teams app (Windows)

• Open Settings > Apps > Installed apps
• Find Microsoft Teams
• Click the three dots > Advanced options
• Under Reset, click Repair
• Reopen Teams

4/ Contact your IT admin
