cannot restore mailbox

Hi Experts,
I try to restore a mailbox to a recovery storage group of my exchange 2007 server.
But the backup is over 1,5 years old and in this time we used exchange 2003.
The name of the exchnage 2003 server was different to the new server I have now.
Now I use exchange 2007.
The restore always fails:

Error category    : Resource ErrorsError             : e000848c - Unable to attach to a resource.  Make sure that all selected resources exist and are online, and then try again.  If the server or resource no longer exists, remove it from the selection list. Edit the selection list properties, click the View Selection DFor additional information regarding this error refer to link V-79-57344-33932

can I still use the old backups and recover to my new exchange 2007 recovery group ?
I don't have an answer to you actual question because i stoped using recovery storage groups because there are serveral tools available that allow you to extract emails directly from an EDB to a pst or to your production exchange. This is especially helpfull when restoring for Public folders. I have some netapp filers so i typically use their tool but i have also had good luck with Digiscope

1. No you cannot use the 2007 RSG to restore a 2003 EDB look at this article at the bottom regarding the limitations.  Basically 2003 and 2007 databases are architected in a completely different way

2. You would need to keep an Exchange 2003 environment active within your environment in order to do this.

3. The product amwinsit recommends will allow you to open the database in demo mode and will show you a true representation of whats available.

4. What are you using for backup?  perhaps there is a way to extract the data without using an RSG

If you have the EDB and LOGS you may try Ontrack Powercontrols or Quest Exchange Recovery.  I have used these to restore mailboxes and emails from the exchange servers

I used Backup Exec for my backup.
I still have the full backup of the server.
But the server is not available anymore.
Check to see if your version of Backup Exec has he ability to restore the files to an alternate location.  If you have this option then I would restore the raw Exchange database files to an alternate location and use a 3rd party utility to open it.
If you don't have the ability to recover the files to an alternate location then I would suggest that you build an Exchange server with the same name, storage group  etc and then attempt the recovery
