In my windows server 2008 R2 OS in the event viewer there is an error pertains Exchange Store DB Error 231 states-(at ’15/04/2013 5:00:14 PM’ the copy of Database ‘Recover DB’ on this server encountered an error during the mount operation. For more information, consult the Event Log on the server for “ExchangeStoreDb” or “MSExchangeRepl” events. The mount operation will be tried again automatically).

What is this error? and what is the actual remedy for this error? .. SOLUTION from Internet and it worked for me.

We had this problem after migrating to Exchange 2010 and then uninstalling Exchange 2003, eventhough replicas of public folders were moved to the new server. Errors would show in the Exchange System Manager, and the following message would occur:
MapiExceptionADPropertyError: Unable to mount database. (hr=0×80004005, ec=2418)
