Additional features, settings, or issues not covered by specific Microsoft Teams categories
Hi Yael,
Based on your description, this issue may be caused by a problem with the local Teams client, corrupted cache files, or a temporary connectivity issue.
To help isolate the cause, I would first recommend following the suggestions provided in the AI answer and testing the affected chats in Teams on the web if you are currently using the Teams desktop application. This can help determine whether the issue is specific to the local client.
In addition, you can also try the following:
1/ Clear the Teams cache
For Windows:
- Fully quit Microsoft Teams.
- Press Windows + R.
- Enter:
%userprofile%\appdata\local\Packages\MSTeams_8wekyb3d8bbwe\LocalCache\Microsoft\MSTeams
- Delete the contents of the folder.
- Restart Teams and sign in again.
For macOS:
- Quit Microsoft Teams completely.
- In the Finder, open the /Applications/Utilities folder, and then double-click Terminal.
- Enter the following commands, and press Return after each command:
rm -rf ~/Library/Group Containers/UBF8T346G9.com.microsoft.teams
rm -rf ~/Library/Containers/com.microsoft.teams2
- Restart Teams.
- For more details, you can take a look at: Clear the Teams client cache.
2/ Repair or reset the Teams application (Windows)
- Open Settings > Apps > Installed apps.
- Locate Microsoft Teams.
- Select Advanced options.
- Choose Repair first and test Teams again.
- If the issue persists, return to the same page and select Reset.
- Sign back in and verify whether the issue is resolved. 3/ Uninstall and reinstall Microsoft Teams
If the issue persists after the above steps, follow the steps in the articles below to uninstall and reinstall Teams.
