How do I remount databases for Exchange 2007 when log files have been deleted? RRS feed

  • Question

  • I am trying to remount 2 databases. The problem started when some log files where accidently deleted. When I try to remount the database I get this error:

    --------------------------------------------------------
    Microsoft Exchange Error
    --------------------------------------------------------
    Failed to mount database 'Alumni'.

    Alumni
    Failed
    Error:
    Exchange is unable to mount the database that you specified. Specified database: CU-EX-STUDENT\Students\Alumni; Error code: MapiExceptionCallFailed: Unable to mount database. (hr=0x80004005, ec=-1032)
    .
    It's the same error for the other database in that group. When I check the event viewer after trying the remount; I get these 2 errors:

    I saw in another posting that a possible solution could be to copy everything from the folder except the databases and then try and remount the databases. It is understood that there could be some data loss involved with this process. HELP!!!

  • Hi

    You should start by running a eseutil /mh pathtodatabase\database.edb

    If the state is Clean Shutdown then you can move all the remaining log files to another folder and mount the database.  If it is dirty shutdown you will have to do a hard recovery which will probably lead to lost data, or restore from backup.

    Cheers, Steve

  • I did as suggested. My databases where in a Clean Shutdown state. I moved all other files to another folder and was able to mount the databases. 

    Thanks Steve.
