I am the admin for my small nonprofit (we have a small full-time staff, with mostly outside volunteers). A while ago I had created a mailing list (actually, a Group Distribution List) with a few internal emails, but mostly external (e.g. @gmail.com
) addresses. It was working fine.
I wanted to upgrade to making that a MS Teams group, so I deleted the Distribution List, and created a team within MS Teams. I added all the outside users as guest users, along with the couple internal users, and that (apparently) went fine. The group is now a Microsoft 365 group, with MS Teams status as "connected." I can see the users in Microsoft 365 admin center, as well as everyone listed in Active Users and Guest Users. Everything looks fine in the Exchange admin center as well.
However - I just discovered that when someone emails the group email, email is surprisingly not delivered to the internal email accounts! The external guest emails are getting their emails. I looked in the internal users' accounts when they are logged into Outlook/Teams and I can't find any place those emails might have gone.
Is this behavior expected? Am I missing some option I need to turn on so internal users receive email send to the group email address?
