When a user who is a member of a role group (defined as a custom management scope so that it contains mailboxes across domains) tries to view detail properties of mailboxes in a child domain, they receive the following error message:
HTTP 500 due to ADReferralException
Note When an administrator tries to view detail properties of mailboxes in root or child domains, they do not receive an error message.
This issue occurs because the Active Directory object is not correctly retrieved.
