Hi There,
During a failed attempt to upgrade the hardware of the production server I have lost the HSM drive to a nasty crush.
It is not a disaster to the company, but I have to tidy up things in order to let the users carry on working without errors.
Currently if they go back in their inbox previous to the HSM cutover date, they can see messages which they cannot open, since the BLOB of the message is lost.
This is obvious however, I tried few mailboxes and done the reindex mailbox, however it didn't solve the problem. It still doesn't delete these messages or pointers to the messages.

Does anyone have an idea of how to remove all the "lost" messages from all the mailboxes in one process?

Thank you very much for your help,
Best Regards,
