Exchange 2010 Mailbox Recovery - Erroring

I have restored an entire exchange database into a Recovery database.  I have mounted this database to the exchange server and it is showing as online.

I have tried using the Restore-Mailbox and New-MailboxRestoreRequest commands and both error.  Attached is the Restore-Mailbox command with errors.

I am hoping that someone will be able to provide some assistance on this issue.  I need to restore this mailbox as the terminated user deleted all their emails before they left.

what is the value of the HomeMDB?

Use ADSIEdit and check if it has the attribute.

CN=Microsoft Exchange
CN=Administrative Groups
CN=Exchange Administrative Group (<ID>)
ddawesAuthor Commented:
In Properties of CN=Databases, there is no property HomeMDB.  Should there be and what should it be set to?
Em ManCommented:
hold on... checking on my Exchange 2010 Virtua Testl Machine.

What about the Property for that username?
are their any HomeMDB?
Simplify Active Directory Administration

Administration of Active Directory does not have to be hard.  Too often what should be a simple task is made more difficult than it needs to be.The solution?  Hyena from SystemTools Software.  With ease-of-use as well as powerful importing and bulk updating capabilities.

Em ManCommented:
*are there any HomeMDB on the users Mailbox Attribute Editor?
ddawesAuthor Commented:
Are you able to provide some more information as to what I am checking?  I haven't used ADSI Edit much.
Em ManCommented:
as I can see on the log, there is some problem with "MELANIE GRIFFITHS"

it could be that some attributes here is missing or incorrect.
Em ManCommented:
I found this similar issue, not sure if you tried this one already as I cannot replicate it from my virtual test machine.

New-MailboxRestoreRequest -SourceDatabase "INSEXMB2RDB1A" -SourceStoreMailbox "Test User" -TargetMailbox mailrecover1

-TargetRootFolder "Test" -AllowLegacyDNMismatch

FYI, I did get the error below when I didn't use the -AllowLegacyDNMismatch parameter, since the Recovery Database is a pre SP1 backup and the database I'm restoring to is post SP1:

"Source mailbox's legacyExchangeDN '/O=COMPANY/OU=SITE/CN=RECIPIENTS/CN=TESTUSER' doesn't match the legacyExc
hangeDN or X500 proxy for target mailbox 'mailrecover1A'. Use the 'AllowLegacyDNMismatch' switch if you want to allow this operation."

ddawesAuthor Commented:
I have also tried using the New-MailboxRestoreRequest command already and it also fails.  Gets to 11% complete then status changes to Failed.

Melanie's account has the homeMDB attribute with a value of "CN=Mailbox Database 0511189085,CN=Databases,CN=Exchange Administrative Group (FYDIBOHF23SPDLT),CN=Administrative Groups,CN=First Organization,CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=aerison,DC=com".  That looks like the correct database her account is assigned to."

Any other ideas? Really need to get this sorted.
Em ManCommented:
hope this one helps found this one on Microsoft site, not sure if you already seen this.


Restore as normal

New-StorageGroup -Server "xxxxxx" -LogFolderPath "V:\RSG\logs" -Name "Recovery Storage Group" -SystemFolderPath "V:\RSG\system" –Recovery

New-MailboxDatabase -MailboxDatabaseToRecover "xxxxxx" -StorageGroup "xxxxxx\Recovery Storage Group" -EDBFilePath "V:\RSG\RSGDB1.edb"

Ensure user is in the restored RSG

Mount RSG in EMC DR and gather merge or copy information to view mailboxes to ensure mailbox is there

Get list of users in mailbox datase and ensure the mailbox is still there:

Get-MailboxDatabase "Recovery Storage Group\xxxxxx" | Get-MailboxStatistics >c:\recover.txt


Create a new datasbase

Create a SG on V drive

Create a database with same name as where the user was

Allow the database to be overwritten by a restore

Suspend SG replication


Move edb to new database

Dismount RSG database

Ensure new database is also dismounted

Copy RSG edb file to new database location

Rename edb file to original name


Ensure user is in the new database

Mount the new database

Get database name:


Get list of users in mailbox datase and ensure the mailbox is still there:

Get-MailboxDatabase "xxxxxx\xxxxxx" | Get-MailboxStatistics >c:\recover2.txt


Reconnect mailbox and export

In EMC go to the new database under “Disconnect Mailbox” and ensure the user is there

Reconnect the user to an account without a mailbox

Open the mailbox

If OK export content to PST file


Clean up

Remove-MailboxDatabase –identity “xxxxxx\Recovery Storage Group\xxxxxx”

Remove-StorageGroup –identity “xxxxxx\Recovery Storage Group”

Are you sure this article relates to Exchange 2010?

I was reading "http://www.msexchange.org/articles_tutorials/exchange-server-2010/high-availability-recovery/uncovering-exchange-2010-database-availability-groups-dags-part1.html" a little while back and remembered seeing the comment "This also means Exchange 2010 does not have the concept of storage groups any longer. Now there are databases and a log stream associated with each database".
Em ManCommented:
nope, this is a 2007 Exchange Server and has similar issues with your concern.
however this only to give you idea for possible resolution.

Been trying to replicate this problem since I have both Exchange 2003 and 2010 on my virtual machines, and can't really replicate this kind of error.
Em ManCommented:

sorry for the delay. any updates?

I've been reading the logs and it the terminated users has a 2GB size of mailbox.

Just wild guess, what is your Storage Limit Policy for the DB where you need to store this employee?
also does the account active in AD is Active?
ddawesAuthor Commented:
No updates on the issue.  Still experiencing the same issue.

Not sure how to go forward with the suggestion above - The commands obviously don't work with Exchange 2010 and I'm not sure what the equivilent commands are.

We do not have any storage limits set on the "Mailbox Database 0511189085" which is where the Exchange Restore account is located.

We have not deleted Melanie's account from AD, so that still exists as well.

No resolution found for issue.
