Hi,
We encountered a problem yesterday with our Exchange 2013 servers. We have 4 Exchanges 2013 servers (2 CAS + 2 MBX).
We also have a DAG with the 2 MBX servers. When we shutted down our secondary MBX server (where the DB were active), the DB switched correctly on the first MBX server, but users could not send emails anymore, they were stuck into the drafts folder of Outlook.
When we started the secondary MBX, emails were being sent as usual.
In event viewer we had several "transport rules agent" warning, but the agent was running.
We tried to shut down the primary MBX server this morning, and everything worked fine.
So it seems we have a DAG with 2 servers, but only one of the servers can be shutted down...
Any help for this issue ?
Thanks
