Has anyone else run into this before with O365 Groups?
We have a senior executive group that scheduled a meeting for this morning. Meeting was sent last Wednesday. The group contains 18 people.
The facilitator (who is also a group member) sent the message to the group email address via Outlook (like a regular invite).
Only 17 of the 18 members of the group received the email invite. I can confirm this doing a message trace on the DL expansion. This user was clearly not on the message trace.
User is a member in the UI, can see an interact with everything in Outlook/OWA, and doing a powershell get members shows him there as well.
