Corrupt mailbox on Exchange 2000 server.

Hello Experts,
 I'm running Exchange 2000 on a 2000 Server box and Veritas 8.5 is my backup software.
My nightly backup reports the following error on one user's mailbox.

WARNING: "Todd Schork" [Todd]?Top of Information Store?Inbox?Outlook Message Manager (Outlook) (Key: B81CBB2E47269B48AB4FF56F07F16B3F)" is a corrupt file. This file cannot verify.

Today I see this message slightly altered, referring to:
WARNING: "Todd Schork" [Todd]?Finder?Unread Mail?Outlook Message Manager (Outlook) (Key: B81CBB2E47269B48AB4FF56F07F16B3F)" is a corrupt file. This file cannot verify.


The user reported missing seven days worth of mail last week which I restored and then yesterday he reported missing a different seven days worth of mail.
His .pst file is 1.4 gb in size and he is the type who never deletes anything. Unfortunately he is the VP and my boss so I won't go there.

I've found two forums mentioning this but the answers led nowhere.

Thanks in advance for any assistance.

That message doesn't actually mean you have a corrupt mailbox. It means that Veritas cannot read the email message.
If you do brick level backup (ie a backup of every mailbox rather than the information store) then you should expect those messages.
Very little you can do other than track down the message that is causing the error report and delete it.

The message name is where I loose it.      Key: B81CBB2E47269B48AB4FF56F07F16B3F

There is no message with this name.

I'm going to run scanpst.exe and check for a corrupt rule on the client.

I don't think scanpst will do a great deal for you as this is an Exchange mailbox, not a personal folder.
The message looks like it might be some kind of hidden message - Outlook Message Manager is the rules system, so it could be the rules database that is causing the problem.

Where is the rules database stored, on the client? I've had him delete his rules from within Outlook hoping that would help. He later got an Outlook popup saying "The rules on your machine are different than the rules on the server, which do you want to use?"
We opted for the server rules.

thanks for participating..

If you want to flush all the rules out, close Outlook totally (check it has gone in task manager), then click start, run and type

outlook.exe /cleanrules

That deletes the lot, including hidden and server rules.
