AD Security Groups removed from Outlook Membership
Image attached.... Why are we no longer seeing the AD Security Groups in this membership view anymore, and how can we get it back. We have a reason why we like it to see it.
AD security groups are not valid Exchange recipients, thus Exchange ignores them. Easier way to check this is via the Get-Group cmdlet, if the group is visible there, it will be visible in the membership tab (for any members of course).
