How to Fix  Microsoft Teams Error caa70007

Clear the Cache

Clearing the cache is one possible solution to fix error caa70007. Maybe all those files stored in the Cache folder are preventing you from launching Teams or logging in to your account.

1. Right-click on the Teams icon in the taskbar if it’s visible there. Select Quit.

3. Locate and open the cache folders below. Delete all the files stored in those folders.
   • \\%appdata%\Microsoft\teams\application cache\cache.
   • \\%appdata%\Microsoft\teams\blob_storage.
   • \\%appdata%\Microsoft\teams\databases.
   • \\%appdata%\Microsoft\teams\GPUcache.
   • \\%appdata%\Microsoft\teams\IndexedDB.
   • \\%appdata%\Microsoft\teams\Local Storage.
   • \\%appdata%\Microsoft\teams\tmp.
4. Additionally, clear your browser cache if you also logged in to Teams on your browser.
5. Restart your computer. Launch Team again and check if the error is gone.
