Can't login to Teams desktop app with error code 800700b7
daniel_liang I have the same issue with several users.
Things we have tried so far:
-Clearing Office Windows credentials in Credential Manager
-Uninstalling and reinstalling Teams
-Deleting and/or renaming %LocalAppData%\Microsoft\Teams\ folder
-Deleting %LocalAppData%\Packages\Microsoft.AAD.BrokerPlugin_cw5n1h2txyewy\LocalState folder and replacing with a text file named 'LocalState' to prevent recreation of the folder
-Removing account from Settings>Email, calendar, and contacts
-Restarting computer
Some of these steps have worked in some installations, but I still have several stubborn installations that won't authenticate correctly, or will auth one time and then go back into error state. Hopefully these ideas will help others who are experiencing the same issue. Some users have temporarily switched to the Teams web app (teams.microsoft.com), although this connection sometimes gets errors as well and needs a reboot to work-around.
Hopefully someone can come up with a true fix for the underlying issue.
Try this:
** Exit/Quit Teams**
1. Make sure there is no other Work or school account under "Email & accounts" . If you see user personal Microsfot account, delete it. If there is no work&school account, create it.
2. Clear Teams Cache (as your mention)
3. Rename folder "Microsoft.AAD.BrokerPlugin_cw5n1h2txyewy"
4. Reboot PC
5. Reinstall Teams desktop client
6. Test it
Thank you

Thank you two. I tried your methods but problem is still here. However, I found that not only did Teams have this issue, I also cannot add a work or school account in setting or Office. There is no popup when I try to add it in setting as well. Maybe that is the point.
