Error code - caa70004

Question

I have trouble signing in to my account. It would get fixed by Reinstalling the app, but not this time. This has been really annoying. I can sign in using my web version on chrome which is not convenient and would crash during a call.

any solutions?

Answer 1

Hello Razzieh,

Regarding your issue, suggest you to kindly try to clear Teams’ cache by follow the below instruction.

• 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.
• Go to File Explorer, and type in %appdata%\Microsoft\teams.
• Once in the directory, you’ll see a few of the following folders:
• From within ‘Application Cache’, go to Cache and delete any of the files in the Cache location.: %appdata%\Microsoft\teams\application cache\cache
• From within ‘Blob_storage’, delete any files that are located in here if any.: %appdata%\Microsoft\teams\blob_storage
• From within ‘Cache’, delete all files.: %appdata%\Microsoft\teams\Cache
• From within ‘databases’, delete all files.: %appdata%\Microsoft\teams\databases
• From within ‘GPUCache’, delete all files.: %appdata%\Microsoft\teams\GPUcache
• From within ‘IndexedDB’, delete the .db file.: %appdata%\Microsoft\teams\IndexedDB
• From within ‘Local Storage’, delete all files. : %appdata%\Microsoft\teams\Local Storage
• Lastly, from within ‘tmp’, delete any file. : %appdata%\Microsoft\teams\tmp
• Once finally done clearing, you can now restart Teams from your local desktop and all cache will be cleared from the desktop app.

Answer 3

I am having the same issue. I have spoken with my IT admin and we have removed multifactor authentication.. signed out of all devices. uninstalled and re-installed Teams.. nothing has worked.

Updated: I did the following and it worked for me...

Clear the Windows Credential Manager

Deleting your locally stored Office passwords may solve this problem. To do this, you need to clear the Credential Manager.

1. Open the Control Panel.
2. Navigate to User Accounts.
3. Then click on Credential Manager.
4. Select Windows Credentials.
5. Scroll down to Generic Credentials and locate your Office credentials. It’s the Microsoft account user line.
6. Then select MicrosoftAccount:user and click on Remove.
7. Restart Teams.
