User Cannot Sign Into Microsoft Teams

Question

Hello

Please i need your help on this issue.

Everyday I have a user that attempts to sign into Microsoft Teams using the Teams Machine Wide Installer.

If we delete the Teams folder in Appdata/Roaming and then uninstall teams/reboot ... It works for a day.

Then the error comes back. Error Code 80070003.

I have even went as far as running dir /S /B and deleting anything that had the word teams in it.

I also got really desperate and started looking up registry keys on google.

They only change I made was this one: Create a registry enrty: HKLM\SOFTWARE\Policies\Microsoft\Windows\WorkplaceJoin, “BlockAADWorkplaceJoin”=dword:00000001

Hi @IBN

Does the web client have the same problem? Then, perform a clean boot to exclude whether a background program is interfering with Teams.

If the problem persists, you could try the following methods to fix the sign-in problem.

1.Windows offer an option to repair the apps.

• Open Windows 10 Settings app.

• Select Repair and let Windows handle the issue in the background.
