Exchange 2010 Dag some users canot connect after failover
Posted on 2011-10-03
I have a strange issue that I do not even understand could be possible. Scenario: Exchange 2010 SP1. DAG created. There are three servers in DAG, two in one site and one in another. Outlook client is 2010. The issue is the following: when database is mounted on server 1, all users can connect fine. When database moved to server 2 in the same site most users can connect but some cannot. Tried to redo profile in Outlook, did not help. When a user that is working fine on Server 2 tries to add additional mailbox through outlook of non-working user, Outlook times out. That tells me that the problem is with specific user inside common database. How could that be even possible? Client is the same, CAS server is the same, database is the same. I would appreciate any help on this.
