I'm managing a hybrid Exchange 2010 environment and have a number of distribution groups which were created on-prem. These groups are syncing via AAD Connect. The problem is, only members with user objects in AD are getting synced. I can see all members - users and contacts - when I view the DG on the Exchange server but when I look at the members in the Address Book in Outlook, I only see the user objects.
Is there a way to get the contact objects to sync up too?
