We're running a three server Exchange 2013 DAG that we moved to from Exchange 2007.
Distribution groups don't appear to be displaying the membership since we migrated to Exchange 2013. In AD the members are there, and if you log in to ECP the members show when you manage the group, and even in Powershell if you do a Get-DistributionGroup -id "GroupName" | Get-DistributionGroupMembers the member show. But when you are in OWA, go to the All Group's address list, and click on a group it says "There are no items to show in this view".
I made sure that the Set-DistributionGroup -id "Name" -forceupgrade was done (didn't need to, says it doesn't modify anything).
Not sure why the members are not showing up?
