Seeing errors on our Exchnage 2010 SP1 server related to one of our databases. Looking to find the best solution to correct the errors and clean any corruption.

Last Modified: 2016-04-06
We have multiple database on our Exchange 2010 SP1 server (Ver. 14.01.0438.000) One database in particular has started to through errors leading us to believe that the database is corrupt. The database only has 2 mailboxes in it, but these mailboxes are both about 15 GB in size. We have tried to move the 2 mailboxes to another database, but they fail each time.

Our Exchange server is running on Windows Server 2008 R2 and is a virtual machine configured through VMware.

We are looking to see what might be the best way to resolve this issue and correct the errors seen. Please let me know if any more information is needed.

The errors we are seeing with the database are as follows:
Event ID: 233- Database Recovery - At '7/24/2015 5:09:38 AM', database copy 'XXX' on this server encountered an error. For more information, consult the Event log for "ExchangeStoreDb" or "MSExchangeRepl" events.

Event ID: 474 - ESE - Information Store (3860) XXX: The database page read from the file "E:\mdbdata\Mailbox\VIP\XXX.edb" at offset 29928882176 (0x00000006f7e68000) (database page 913356 (0xDEFCC)) for 32768 (0x00008000) bytes failed verification due to a page checksum mismatch.  The expected checksum was [da2b25d4b6fe068f:a2c8a2c80d692cc3:74e374e33eb21e4a:0899f76628ced59e] and the actual checksum was [da3e25c1c817f35a:930c930c99913cc8:7d427d42ecc6c3f1:0899f76628ced59e].  The read operation will fail with error -1018 (0xfffffc06).  If this condition persists then please restore the database from a previous backup.  This problem is likely due to faulty hardware. Please contact your hardware vendor for further assistance diagnosing the problem.

Event ID: 203 - Database Recovery - At '7/24/2015 5:10:05 AM' database copy 'XXX' on this server appears to have an I/O error that it may be able to repair.  To help identify the failure, consult the Event log on the server for other storage and "ExchangeStoreDb" events. Service recovery was attempted by failover to another copy. The failover was unsuccessful in restoring the service because of the following error: 'There is only one copy of this mailbox database (VIP). Automatic recovery is not available..

Thank you in advance for any help given.
