We have a 2 node stretched DAG, with one mailbox server in main office and another in Disaster Recovery site. We have a public folder database in main site that replicates to Disaster Recovery site. Over the weekend one main site will be completely down for maintenance. We will be failing over to the mailbox server in DR Site. What needs to be done for outlook users to be able to access the replicated public folder database on mailbox server in DR site. Also when the main site is back how do we point it back?
