Some recent questions in the Microsoft Technical Community show confusion about the email addresses used by Office 365 Groups and Teams. Here’s our attempt to clarify.
Exchange Online distribution lists can be used to populate the membership of Office 365 Groups or Teams by applying a little PowerShell magic. Here’s how.
A reader asked if it is possible to add an administrator account to every Office 365 Group. This feature doesn’t exists OOTB, but it’s an easy task to script with PowerShell.
By default, the Groups policy for an Office 365 tenant allows group owners to add guest users to group membership. You can block this access if necessary, but it’s probably not what you want to do as blocking brings guest access to a complete halt across the tenant.
When you impose a block on certain domains, you’d like to think that applications like Teams will respect that block. As it turns out, if you have some lingering guests in your Azure Active Directory, the B2B collaboration policy might not be as effective as you’d hope.
