We recently transitioned from Exchange 2003 to Exchange 2010. When we had Exchange 2003, we were able to use Active Directory Users and Computers to create the Distribution List, Add Members, and it would populate in the Global Address List. Now when we do this, it doesn't appear to be working, and the names aren't appearing in the Global Address List. I also don't see the Distribution Groups appearing in the Exchange Management Console > Recipient Configuration > Distribution Group.
Does this mean we no longer can create our distribution groups using the ADU&C console?
I have the distribution groups created in active directory, do I have to remove them and then add them to the Distribution Group in EMC, or can I keep them, and just create them again in the EMC?
