If you want to clear MS Teams cache,you could refer to the following ways
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 or .ldb 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” and”%AppData%\Microsoft\Teams\Backgrounds”
For macOS, this would be the magic folder: /Users/user_name/Library/Application Support/Microsoft/Teams. (thanks to Lucian Naie (@lnaie) for the contribution)
