Cannot add guest account to Teams
Well, just got off the phone with their support and they were able to replicate the same exact issue. They said the issue is that not all tenants have been updated yet, which I guess answers the question as to why some are able to do it, and others not. Unfortunately they didn't have a timeline yet as to when everyone will be cut over.
*Resolved* this error of "you are not authorized" by logging in to O365 (web interface) > click/open/see "Groups" by clicking on the "people" icon, then select the Team to add a guest...
In the right pane click on "Guests" and then "Add Members" and enter the external users email address (Be sure to click "Save" after entering the email address in the right most pane
After you complete "adding a user here to your Azure directory" then you are able to to in to Teams and "Manage Teams" and "Add member" and not get message "you are not authorized"
It already worked this way before. But users, added this way are not able to use Teams if the accounts added are not defined in any Azure AD.
As I already mentioned before, adding guests to Azure AD works fine, but even after adding those users to teams they are not able to use Teams if accounts added are not School or Business accounts.
If you like to Guest use Teams, you have to assign licenses on O365 Admin Panel for this Guest account. This will slove your problem and no is not on DOCS
