On a Windows Server 2008 R2 Sp1 server, after Exchange 2010 is complete, I open Exchange and the Mailbox states it is unmounted, attempting to mount it fails with the following error: ------------------------------------------------------- Microsoft Exchange Error -------------------------------------------------------- Failed to mount database 'Mailbox Database 1876052673'. Mailbox Database 1876052673 Failed Error: Couldn't mount the database that you specified.

I was able to create another Mailbox successfully, but how do I remove the one that doesn't exists??David Baur

'C:\Exchange2010\Mailbox\Mailbox Database 1876052673' is not the default path. please check the output of get-mailboxdatabase |fl and any events in event viewer. does the folder exchange 2010 exists alongwith subfolders, if not can you create it manually

Hi David, There are two ways to do it. 1: Remove the Database from EMC and if you are not able to remove it than. 2: Go to Adsiedit.msc...>Configuration...>Services...>Microsoft Exchange...>ORG...>First Admin Group...>Exchange Admin Group...>Database...> Check the name "Mailbox Database 1876052673" and delete it. After deleting it from here open EMC and you should not get that error message. * Note: Do not play around in Adsiedit.msc until or unless you are sure that, you know what you are doing...

Hi David: As far as I know, they are not big issues. Make sure that all folders exist that are given with the error and re-created it by hand. Many users solve it by this way. You can mount it and then remove it. If it doesn’t work, Gulab has offered adsiedit.msc to solve it.
