Restoring from MS-Backup of exchange. Deleted e-mail messages not being restored.

I'm trying to restore some e-mail messages I deleted. Its no big deal if I cannot retrieve these, but I am concerned for other situations. Here is some background:

The server is MS-Exchange 2003 (6.5.7638.1).  The client an Outlook 2003 sp2 client. The mail is delivered to the exchange mailbox. Mail has been delivered OK for months. I have a nightly procedure that uses NTBackup to save the exchange Information store.

I discovered some a missing Outlook folder.  I attempted to restore from the NTBackup I made about a week ago. I:

- Made a temporary NTBackup of the Exchange Server's Microsoft Information Store.
- Signed on to users and Exported their mailboxes to disk (I just dont trust MS).
- Dismounted the Server's Mailbox Store and Public Folder Store
- On the Mailbox Store and Public Folder Store properties, checked the "This database can be overwritten by a restore" box.
- Ran NTBackup to restore the database to a week ago. (Approx 1.5 gig, took about 5 min, seemed to be doing something)

The messages were not restored. I tried this several times. I sometimes get logon messages:

Unexpected error <<0xc1050000 - Unknown Error. The logon to the Microsoft Exchange Server computer failed. Microsoft Exchange Server

Just to check, I deleted a message in my inbox that has been there for about a month. I tried to restore from the backup I made a week ago, and from the temporary backup I made this morning. It did not restore.

I see a message that looks OK but I better mention it:

The information store database "First Storage Group\Public Folder Store (SVR02)" was restored from a backup - it has been patched. Please backup this database.


I actually see no evidense that the restore did anything. Any ideas what am I doing wrong?

If you are using Exchange 2003, then why were you not using the recovery storage group? You wouldn't have to restore to the live server.

I never heard of it. Found this writeup in MS TechNet, titled Using Recovery Storage Groups in Exchange Server 2003:

http://www.microsoft.com/technet/prodtechnol/exchange/guides/UseE2k3RecStorGrps/8bcc6e38-363a-43ad-9c43-3f558a435b06.mspx?mfr=true

Now that I recovered my data, do I need to do anything to the Recovery Storage Group? The above document doesnt address that.

Just drop it and delete the files. You shouldn't leave the RSG in place unless it is required.
