sign out of your other accounts
Unable to sign in to Admin account of Teams (Free). Endless loop of seeing this message when trying to sign in and clicking "Sign out" button.
"To start using Teams with firstname.lastname@example.org, sign out of your other accounts".
When I try this in InPrivate mode on Edge it goes into an endless loop with the url "https://teams.microsoft.com/go#" and eventually goes back to the sign in page.
I normally disable 3rd Party cookies but disabled this setting and the problem still occurs.
When trying to sign into the Teams account for business (using work email) this shows I'm signed in with two accounts but if I sign out of the outlook.com addrss the same issue occurs.
I've tried deleting the browser cache and cookies for the teams domain al to no avail.
2020 and problem still continues.
I can login to portal.office.com, account.microsoft.com and skype.com using the outlook.com address without issue.
