Error "We couldn't add member" when adding users to Teams


When you add an internal or external member to Teams, you see the following error: "We couldn't add member. We ran into an issue. Please try again later." However, members can be added directly to Office 365 groups.


This issue occurs when the value UsersPermissionToReadOtherUsersEnabled is set to False in AAD. To correct the issue, change this setting to True.
