Due to some internal reason we performed Disaster Recovery of Exchange standard 2003.
We recenty did a disaster recovery on the Exchange standard Server with Service Pack 2. The new server is also running Exchange standard server SP2. The new server is now working very well.
But the problem is that the mailbox is getting frequently dismounted. One we mount the mailbox store, then everything is working fine, but after sometime it again dismounted.
Need your help to solve this problem.
