Hi,
we use hybrid Exchange environment and I want to give permissions for us IT admins to a shared mailbox. I enter our group and Outlook does not show this Mailbox after some time in Outlook. If I add us as users - then it works.
P.S. The group is Mail-enabled and I can see the group in O365 console with the members.
Could it be that the the groups are not supported?
Cheers
