We are using the free version of Teams and have a little over 150 users. Recently we encountered a weird issue after adding a couple of new users. The user was invited to the org just like everyone else, received the welcome email, followed the link to setup their account, signed in to Teams successfully, but then hit a dead end with this:
The same thing happened to another user that was created a few days later. We have tried to remove the user, re-add the user, re-send the invitation, but nothing changes. It's like they are half-in / half-out. The users can't directly chat with another user either.
Yesterday, I created a test user, but surprisingly, was able to go all the way and get that test user connected to Teams with no problems at all. The settings in Teams don't have much granularity when it comes to checking the status of users, so I am perplexed and not sure how to resolve this problem.
I tried contacting O365 support, but they won't help a free account and directed me here. I'm hoping the brilliant minds here can point me in the right direction.
Usually it’s due to them being cached to another account than the email it was sent too or something like that.
Not sure exactly how to fix but you could try going to portal.azure.com and you should be able to as the free teams org owner go into azure active directory there and find the guest accounts and delete them. Then go through process of inviting again. If that don’t work do it again and make sure they use incognito when accepting invite.
Honestly I think there was a bug recently that may have been fixed at the time you tested it cause I’ve seen a handful of these complaints recently. Anyway give that a whirl and hopefully it works out.
