Exchange 2010 Store will not mount.

Ok, since this afternoon our store won't mount.

After several eseutil actions (/d /r /p) it still will not mount.

Does anyone have any idea how to fix this?

Was one of your troubleshooting steps to  reboot the server / restart Exchange,  and see if this message still persists  while attempting to mount a database?

Check    Windows ADMINISTRATIVE Tools >  Event Viewer
Look at the application log    and system log  for potential error or warnings events in greater detail.     There may be another condition on the server preventing communication from  Exchange management to  database management.

Please let us know which if any error event codes you see.

Potential  other remediation steps

Step 1.  Restart the Microsoft Exchange Active Directory  Topology service and try again.
Verify the system clock on the Exchange server is in sync with the system clock on your domain controllers,  and there are no authentication issues.

Step 2.
Make sure the  Microsoft Exchange Information store, Exchange Service Host, and  Microsoft Exchange System attendant services are in a running state on the mailbox database server.

Communication errors are most likely a result of one of the Exchange services not running on the server  (usually  Information Store).

I would suggest running the "Exchange Best Practices Analyzer"  in the management console, to flag potential issues with the AD or Exchange deployment.

This error code can also be caused by an issue with the HomeMDB  attribute of the Exchange attendant service

Hi Mysidia,

After looking at the log files I coma across the following:

Error 0x3ee starting the Microsoft Exchange Information Store.
Failed to start virus scan.

I have de-installed the virus scanner because I thought it interfiered with exchange.

Must I re-install the anti-virus software? would that be an option?

I got it. After re-nstalling the AV software which I removed this afternoon, the store service could be started and the database could be started again. It seems that the av software has a "hook" inside the edb database, and if it's not removed in a propper way it stays inside the store and prevents it form mounting.
