Teams login chaos since I deleted my old "=EXT" user in tenet and recreated one.

Question

Dear Microsoft team I somehow messes up my Microsoft account completely. It was first a live account back in the days and after some invitations from Team servers (from other companies) a tenent got automatically created for this user I guess. However years later I created an own tenent in order to give access to multiple user to the partners backend and took over the domain of the automatically generated tenent. In this progress my MSA also got copied. Then I deleted this one, because it had an "=EXT" suffix and recreated one with the actual domain. Since then I can't log-in anymore in teams and lost all connections to the other teams invites. Is there a way to fix this mess? When I try to log-in with the desktop client I get this error: ![57614-error-teams.jpg][1] I also tried to enter over the browser. Tried sever browsers and in incognito mode. In the browser I manage to get to our own tenent teams instance, but when I try to access an invite the page keeps on reloading forever. Thanks for your help in advance!

Hi @Goran Saric ,
Thanks for your feedback!

We recommend you try to delete all the Teams-related entries under Credential manager, sign out of Teams, then exit the application. Try to login again and switch to the new tenant. If that doesn't help either, repeat the process, but this time apart from the stored credentials, delete everything in the Teams AppData folders, apart from the actual client.
