the copy of database 'Mailbox Database 1836089144' on this server experienced a performance problem. Failover returned the following error: "There is only one copy of this mailbox database (Mailbox Database 1836089144). Automatic recovery is not available.". For more detail about the failure, consult the Event log on the server for other storage and "ExchangeStoreDb" events.
Can i just duplicate this DB? I'm fairly new to exchange. Thanks in advance.
