Steps to fix “Unable to mount database. (hr=0x80004005, ec=1108)”.

Ever stuck with this error comprising “Unable to mount database. (hr=0x80004005, ec=1108)” The one of a kind Exchange server-not accessible error ensures that the Exchange doesn’t work even after trying soft recovery with Inbuilt Exchange utility including eseutil /r and eseutil /d.

These Exchange server error messages are simply not acceptable as these grill the Exchange Administrators. One such error displays as “unable to mount database. (hr=0x80004005, ec=1108)”. Troubleshooting for these errors does not yield any results and Exchange server simply refuses to budge. How should you fix such stubborn error?

Exchange may be facing dirty shutdown situation. Try the following commands in sequence to resolve the error and you should succeed:

When inbuilt utility Eseutil /r and Eseutil/d doesn’t yield favorable results, try to move checkpoint and logs to a temporary location and again try to mount the database. It should work with this proposition.

If not, then try to use eseutil  /p   and   then eseutil /mh to see the result. It should say "Dirty Shutdown"

Though it is not a hit-and-trial method to fix an Exchange server issue, you have to keep trying different combinations. 

The next step is a series of steps:

Steps to fix:

eseutil /mh *.edb
eseutil /p *.edb
eseutil /mh *.edb

Then move all the log files away from Exchange log folder:


To a log corrupted storage.  Mean that you need to specify the EDB (mailbox DB) file location:

In this scenario it was a combination of following steps:

eseutil /mh e:\MailBox\domain\mail.edb
eseutil /p e:\MailBox\domain\mail.edb

Note: Before moving the log files to the specific database you need to check if database has enough free space available. You need to extend the drive to accommodate the Exchange database and not let the server error hit again for want of space.

However, the above commands may resolve the dirty shut down error but the problem of database could not mount may persist.

Repeated efforts, lengthy commands, online help and Exchange Administrator efforts may not yield the right results.
The only way to resolve such undefeated errors is Stellar Phoenix Mailbox Exchange Recovery software which resolves the problem of dismounted database.

To summarize

Exchange Administrators should have a backup plan when the database is unable to mount and exchange backup is not available. Using inbuilt utilities is a good option but doesn’t suffice for time loss as the Exchange server goes down for long timeframe. It is a known fact that Exchange is crucial for organizational communications and communication-link should not be left dysfunctional for prolonged periods. Have an additional backup plan of Exchange recovery software for such irrecoverable situations.
