One of the departments at our University is planning to use Teams to host a virtual conference in January. This will involve adding 500+ guests, so the GUI method is not going to be practical. I'd prefer to use Powershell to do it since it's fairly easy to pull in lists of emails from a CSV file and loop through them.
The MicrosoftTeams module in Powershell does have an "Add-TeamUser" cmdlet, but it requires that the user already exist in Azure AD (either a native user or a guest who has been invited). OK, so there's another cmdlet in the AzureAD module - "New-AzureADMSInvitation" - that can be used to invite them.
So, my plan is to run New-AzureADMSInvitation to send the invitations, then Add-TeamUser to add them to the Team. Here's the problem: if they haven't accepted the invitation, the typical "You've been added to a Team" email is not sent. So, I somehow need to be able to know when/if they accept the invitation, so I can then add them to the Team.
Unless there's some better method for this that I'm totally overlooking or unaware of. Also, to be up-front, I am not a Teams or Global admin, so don't have access to the Teams admin center. I do have a SharePoint admin role, but that doesn't really help in this situation.
