Running MS Exchange Server 2010 SP2 in a parent/child domain architecture - functional level 2003
Cannot get Universal Security groups to work with mailboxes.
Users in the group do not have access, if I apply them individually they do.
When I apply a USG to a mailbox where does the ACL get added in AD. If I add specific users I can see them listed in AD field msExchDelegateListLink
Cannot see the group object applied to the shared mailbox AD object though.
Many thanks for any help offered.
