Hi Guys, I have Exchange01(200+ mailboxes) on production environment and Exchange02 on the same network but don't have any mailbox on it. Now i m planning a disaster recovery plan and assumed if something gonna wrong with "Exchange01" and i have .edb backup with me for this server. then i can mount this .edb database to on Exchange02 but when i tried to do so in testing lab. i was failed and the error was see below:- Microsoft Exchange Error -------------------------------------------------------- Failed to mount database 'Mailbox Database'. Mailbox Database Failed Error: Exchange is unable to mount the database that you specified. Specified database: EXCHANGE02\First Storage Group\Mailbox Database; . Error code: MapiExceptionCallFailed: Unable to mount database. (hr=0x80004005, ec=1011) -------------------------------------------------------- OK -------------------------------------------------------- As you know that Microsoft claimed Database Portability features in Exchange 2007 then i think it must be happened in another way. Please help me out here ! Thanks Amit Rawat

Hello, You might want to try checking the "This database can be overwritten by a restore" option before acctually trying to mount it. Let me know if that helped. Thanks, Mihai

Did you follow: http://technet.microsoft.com/en-us/library/aa998340(EXCHG.80).aspx How to Restore a Mailbox Database to a New Server with Database Portability Keep piece is that you allow the database to be overwritten by a restore and the files are in the correct location

Thanks for Views, But i did it my own, I have checked Database shutdown status and found it was in Dirty Shutdown state. I have converted it in Clean shutdown and mount on another server. Now after playing a little poweshell game with logs i m able to mount it on next server. Now everything seems fine. Thanks to microsoft for this feature and Thanks to all of you for your Views. Thanks
