Hi JennifaJ G,

Thank you for your reply. Regarding this issue, kindly try to resolve the issue from clear cache of MS Teams, if it can work for your issue.

1.    Fully exit the Microsoft Teams desktop client. To do this, either right click Teams from the Icon Tray and select ‘Quit’, or run Task Manager and fully kill the process.

2.    Go to File Explorer, and type in %appdata%\Microsoft\teams

3.    Once in the directory, you’ll see a few of the following folders:

-         From ‘Application Cache’, go to Cache and delete any of the files in the Cache location. “%appdata%\Microsoft\teams\application cache\cache”

-         From ‘Blob_storage’, delete any files that are located in here if any. “%appdata%\Microsoft\teams\blob_storage”

-         Within ‘Cache’, delete all files “%appdata%\Microsoft\teams\Cache”

-         Within ‘databases’, delete all files “%appdata%\Microsoft\teams\databases”

-         Within ‘GPUCache’, delete all files “%appdata%\Microsoft\teams\GPUcache”

-         Within ‘IndexedDB’, delete the .db file “%appdata%\Microsoft\teams\IndexedDB”

-         Within ‘Local Storage’, delete all files “%appdata%\Microsoft\teams\Local Storage”

-         Lastly, from ‘tmp’, delete any file “%appdata%\Microsoft\teams\tmp”

Once finally done clearing, you can now restart Teams from your local desktop and check if the issue disappears.

Also, if the issue still persist, kindly try to clear all the MS Team credentials from the Credentials Manager from Control Panel.  For clearing credentials > go to Control Panel > select User Accounts option > select Windows Credentials option > remove all MS Team credentials and check that if the issue disappears or not.
