Is there a tool out there that I can open the Microsoft Exchange stm file to view the content and possibly search a string of text as well?

Just the stm file? Not really possible. the stm and edb together constitute the store.Why the need to just search the stm?

I agree with Andy. You shouldn't search just the STM. What are you trying to accomplish?Mark Morowczynski|MCT| MCSE 2003:Messaging, Security|MCITP:ES, SA,EA|MCTS:Windows Mobile Admin|Security+|http://almostdailytech.com

A few email messages were sent from 2 years ago and my collegue wants to search through the .stm file for record as it picked up a string search from the Windows search. I've already used the MFCMAPI in the SMTP mailbox and couldn't find anything.
