Hello,
Our team is involved in migration of Exchange 2007 deployed in three sites. In every site an Exchange 2013 CAS and Mailbox role servers were deployed.
The question: should we change the AutoDiscoverServiceInternalUri on Exchange 2007 CAS servers to point to Exchange 2013 CAS?
Exchange 2013 CAS will give to Exchange 2007 clients the correct legacy information (like legacy.contoso.com) instead of mail.contoso.com (primary namespace moved from Exchange 2007 to Exchange 2013)?
Thanks,
Andrei Moraru Endava
