Because of various problems - up to and including the issue I'm working on with the certificate pop-up - it has been proposed to simplify the Exchange 2010 environment. Currently consisting of 2 DAGs - we're looking to consolidate into one. In the attached drawing MB1 through MB4 would be one DAG. Site 1 and 2 have users, Site 3 is DR only. All 3 sites connected by MPLS. We would like, in worst case scenario, if Site 2 was completely disconnected from the others, that the users there would be able to send local email to each other. We were told by a vendor that would happen as laid out in this diagram and, that once connectivity was restored the email would sync back up to the other servers. I always understood that in DAGs with even-numbered members that we would need a witness server. And, if a DAG member couldn't see the witness or form a quorum, that the Information Store service wouldn't even come up on the server. I'm I right? This wouldn't work as stated? Looking for a checksum... -Paul
