Below you can see that I am trying to restore a mailbox. I have restored and mounted the Mailbox database and then trying to restore a folder for a user which was accidentally deleted. You can see that the error say it can not find the mailbox but using get-mailbox command it find the mailbox.

Please HELP!!!!!

Are you on RTM or SP1? I would recommend you go to SP1 if you are not already on it As an alternative you may want to check out Lucid8's DigiScope http://www.lucid8.com/product/digiscope.asp since it can open Offline Exchange Databases without the need of an RSG and you can browse or search through all mailboxes, folders, items etc and then Export to PST MSG & XML or recover the data directly to a production Exchange server. here is a quick flash demo for you to check out as well http://l8downloads.com/FLASH/DSWEB/DigiScope_Overview.html Troy Werelius


I know there are many tools out there which allows you to restore mailboxes or DB's

But I would like to do it within Microsoft. Using the restore cmdlet.

I think the issue is that this command does not want the email alias, it wants any of the following three things to identify the Mailbox: DisplayName, LegacyDN, or ExchangeGuid. These are the same things that are used for StoreMailboxIdParameter. It doesn't matter what is unique per domain, it matters what information is stored in the actual mailbox database as opposed to AD (as AD is bypassed to mail Restores possible).
Re-run it with the users DisplayName as it appears in AD and the command should work if for some odd reason that doesn't work try the ExchangeGuid Troy Werelius


I'm having the same issue, and found that you must use the display name (and probably in quotes e.g. " Last, First Mi." - Also, from my experience, you may have to use the New-MailboxRestoreRequest as a result of SP1. I was able to get the cmdlet to succeed, but the job fails at 5%. here is the syntax for the new-mailboxrestorerequest:

New-MailboxRestoreRequest -SourceDatabase " Recovery Mail Store" -SourceStoreMailbox " Lastname, First Mi." -TargetMailbox " Lastname, First Mi."

If you need to only restore certain folder, then use the -SourceRootFolder (before the -Targetmailbox) and likewise if you want to restore to a different, then use -TargetRootFolder at the end. Also, you may need to put -AllowLegacyDNMismatch at the very end (if you get an error running it w/o regarding legacyDN, slap that to the end of your cmdlet.

Let me know if this works for you. As I stated, mine queues and executes, but fails after 5%.



Hey Troy,

I have tried Display name, Alias, Username, email address and none of these work....

Anything else I can try...


Sam, do a Get-MailboxStatistics -Database " Name of Recovery DB" and see if the name is in there and the way in which it is displayed. Also, can you provide the exact syntax of the restore command along with output?Karl
