Last week I suddenly could not login to Teams desktop app with my school account on my PC. The error code is 800700b7. Normally when I login the app, it will pop up a window to let me login to school system.
I tried to uninstall and re-install it and clear the cache, but all can't work. There is no system updates pending.
However, I can login with my personal account on my PC. I can login with my school account on my android phone and in browser on my PC. I can login with my school account on school computer as well.
I asked IT admit for help, but they are hard to fix it.
Hope anyone can help.

@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
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.

** 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

@daniel_liangI was able to successfully resolve this issue by following the uninstall steps mentioned in the following Microsoft article: https://support.microsoft.com/en-us/office/uninstall-microsoft-teams-3b159754-3c26-4952-abe7-57d27f5...
Please note that I had to uninstall both Microsoft Teams and Teams Machine-Wide Uninstaller as mentioned in the article.
Also, I cleared the Teams cache as mentioned by others in the post.
After uninstalling both apps, clearing the cache, and reinstalling teams from https://www.microsoft.com/en-us/microsoft-teams/download-app#desktopAppDownloadregion I was able to successfully recover from this issue.
I hope this helps.

@pkhetarp thank your reply. The problem was solved automatically several months ago but I still didn't know what actually happened. Hope your method can help other people.
