How to restore users email from Dail Tone Database for exchange 2007

We had an email database crash in January and brought the users up on a dial tone database.  The DB mounted in a recovery storage group without any problem so the DB was flipped back and new data merged back, but then it crashed the database two more times after that.
We need to restore the users data from the Dial Tone DB.
What is the best way to merge this data back?

Well I found a third party software tool out there that you can restore emails from wether the db is mounted or if the db cannot be mounted. You can restore all of the emails or just a few, depending on what you need. I was able to export the users from the defective db to pst files and then was able to import them back into outlook..
Here is the link to the great software: http://www.lucid8.com/

Yes we do have backups
So are you saying to create another Dial Tone DB and then restore it again?
There was only 40 users that were affected, the rest of the users email is ok in the normal database.

Can I do the migration to a  PST file?

Malli BoppeCommented:
yes you can. If you have backups. Create a RSG and then you can export to PST's.

Exactly. You cannot restore mails direct into PST, so you will have to restore it to any temporary mailbox by creating RSG and from there export to PST.

Ok we already have the users affected email in the a RSG so what steps would I do to migrate them to a pst from there?
Would I have to dismount the db to do the restore to a pst?

You can't  directly extract the mailbox to a PST file. You need to restore the mailbox to a folder on a anther mailbox and then create a PST file.
Instead of that just export the old mail to the user mailbox. The command is

Restore-Mailbox -RSGMailbox 'USERA' -RSGDatabase 'EXCHANGE\Recovery Storage Group\Mailbox Database' -id 'recovery' -TargetFolder 'OLDEmails'
