Answer 1

I had the same error code(caad0009) today, and after several hours of troubleshooting I found out that it was a corrupt MicroSD card I had inserted couple of days a go, which prevented MS Teams and OneDrive from starting or signing in.

Answer 2

Hello Evija,

Thanks for your post in Microsoft community. Since issue persist only in Teams client app on your PC, suggest you to clear Teams cache and then check the result.

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 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.

If still issue persist, check there is no firewall and antivirus block Teams client app. For further analysis we request you to kindly provide entire screenshot of your error message, so we can help to check further.

Thanks and regards,

There's a more permanent way to sign in to Microsoft Teams. If you're having trouble completing the process, talk to your IT admin

Answer 4

I had this issue and compatibility mode fixed it for windows 7

Answer 5

Same for me. It's working under another user, but how to fix the problem for the main one?

I have tried all the methods above, uninstall the program, clean all files and registry, but nothing helps.

Even then I trying to login under non-existing account, I have got the same error.

We're sorry—we've run into an issue.

Restart

If that doesn't work, try signing out and back in.
