Hi GagandeepKaur-7859,
Does this error message show “Your computer’s trusted platform module has malfunctioned”?
You could clear the client cache as the following steps:
- Fully exit the Microsoft Teams desktop client. To do this, either right click Teams from the Icon Tray, select ‘Quit’. Or run Task Manager and fully kill the process.
- Go to File Explorer, and type in %appdata%\Microsoft\teams.
- Once in the directory, delete any file in the following folders:
%appdata%\Microsoft\teams\application cache\cache
%appdata%\Microsoft\teams\blob_storage
%appdata%\Microsoft\teams\Cache
%appdata%\Microsoft\teams\databases
%appdata%\Microsoft\teams\GPUcache
%appdata%\Microsoft\teams\IndexedDB
%appdata%\Microsoft\teams\Local Storage
%appdata%\Microsoft\teams\tmp
If no luck, you can try to remove and read your account to Windows. Then uninstall and reinstall Office.
