Unable to add External user to Teams

Question

I am unable to add an External user to Teams from within the Teams App. (see screenshot)

When attempting to add the user via the Microsoft Teams Admin Portal, the search results with "We can't find any team members to add."

I have turned on the appropriate settings as outlined in the following article: https://learn.microsoft.com/en-us/microsoftteams/set-up-guests#:~:text=Configure%20guest%20access%20in%20the%20Teams%20admin%20center,allow%20for%20guest%20users.%20...%205%20Click%20Save.

Answer 1

Issue: the user in question has been both added and removed as a "guest user" of our organization. This caused issues for Teams when attempting to add said user.

Resolution: Add the user manually to the organization (as a guest user) and then to the Team via the Azure portal.

This resolution was reached in conjunction with Microsoft Support

Answer 2

Hi @Frank Hernandez ,

To add the user as a guest into Teams, please firstly check the B2B external collaboration settings to ensure that sharing with guests is not blocked. Note the settings in the Collaboration restrictions section. Make sure that the domains of the guests that you want to collaborate with aren't blocked.

Then go to Teams admin center to check if you allowed the guest access in Microsoft Teams. It may take up to twenty-four hours for the Teams guest settings to become active after you turn it on.
