I moved my First Storage Group to another server, but had an error at completion. It successfully moved the database, but had some verbiage relating to a network error and could not mount the database automatically. The path in the storage group is correct but when you try to mount the database, it gives the error " At lease one of this store's database files is missing. If you continue, a blank database will be created". Is this a permissions issue? If a file is truly missing, how would I go about figuring out what it is? I read in one blog that the path on the new server had to be exactly the same as the one you moved it from. Is that true?Thanks in Advance!!kw

Kwfogo, The path only has to be the same if your running a CCR cluster, when doing a mailbox move all the information is exchanged between the servers and the Active Directory object. During the move did you copy the error just in case? Check the event viewer of the server that you received the error on and see if you can provide a bit more detail. Also "move" is vague elaborate as in you moved it from Server A to Server B vai the GUI or Cmdlet, Or moved it from Server A D: drive to a new LUN the SAN team gave you called E: because of space issues.

HI,Please let us know error which is you saw during mailbox Moving ?Base on my knowledge you can move onlymailboxes between Servers.RegardsChinthaka

I remember that the message indicated that the move was successful, but it stated that it could not remount the db due to a network "issue" and to try to mount the db manually. I didn't realize it was an "error" until I tried to mount the db manually. :( I used the GUI to perform a Move Database Path on the Mailbox Database located in Server Configuration/Mailbox. I first created a new directory on a different physical server, then executed the command. I found message #1 below in the event log in the time frame following the move. The .edb file does exist on the new server. After 30 minutes message #2 started.I also just noticed that the login account used for all Exchange services is the local admin account. Could this be the issue? If so, can I change all the logins to a domain admin account?1) The Active Directory indicates that the database file M:\Exchange\First Storage Group\Mailbox Database.edb exists for the Microsoft Exchange Database "/o=FogoDeChao/ou=Exchange Administrative Group (FYDIBOHF23SPDLT)/cn=Configuration/cn=Servers/cn=MAIL1/cn=Microsoft Private MDB", however no such file exists on disk.

HI,I have reproduced your issues in my lab and should appeared event ID 4001 in Application event log.The SYSTEM and CREATOR OWNER Accounts should be given full control permission on whare you place mailbox database. Pleasecheck Database folder have proper permission.Resource========http://technet.microsoft.com/en-us/library/bb217895.aspxRegardsChinthaka

Event ID 4001 is correct. I had SYSTEM but not CREATOR OWNER so I added it with full control and tried to mount the database but received the same error. Justto clarify, Exchange is on server A and the db is now on server B. I tried to let it create an empty db on server B and received the following message: "Exchange is unable to mount the database that you have specified. Specified database MAIL1\First Storage Group\Mailbox Database: Error Code:MapiExceptionJetErrorDatabaseInvalidPath: Unable to mount database. [hr=0x80004005, ec=-1217]The folder that contains the edb file has CREATOR OWNER and SYSTMEM but the actual edb file does not? If I try to add this, it saves, but then the system deletes it.

HI, I am confused on below sentence, SO please let me know what you mean."Exchange is on server A and the db is now on server B"If Exchange installed Server A but Server B doesnt hold Exchange?RegardsChinthaka

Hi Microsoft does not support network-attached storage with exchange server. If you want more information, please refer to below links: http://support.microsoft.com/kb/317173 http://support.microsoft.com/kb/839687 Hope useful for you!
