Twice now over the past week or two, I’ve had a problem with server-side rules failing to run on our Exchange 2007 server. We use journaling with our archiving system, so every message to/from our organization is sent to a journaling mailbox. There’s a server-side rule on the mailbox to forward all inbound messages to our archiving company and the delete them. Pretty straightforward. Two weeks or so ago, the rule just stopped processing. Messages piled up in the inbox by the thousands. The fix was easy enough—I logged into OWA, deleted the rule, and recreated it. Poof—it started working again. I was confused about why it happened, but didn’t give it much more thought. Then yesterday, the rule stopped working again. Again, messages piled up in the inbox. Again, deleting and recreating the rule fixed the problem. The fix is easy, but I shouldn't have to keep doing this. What could be going on?

Create Transport rule instead of create server side rule. How to use Transport Rules in Exchange Server 2007:: http://www.msexchange.org/tutorials/Transport-Rules-Exchange-Server-2007.htmlAnil MCC 2011,ITIL V3,MCSA 2003,MCTS 2011, My Blog : http://messagingschool.wordpress.com

Thanks for the tip! I've never played with Transport Rules, but from looking at that article they seem to be pretty straightforward. And from what I can tell, they would work fine for what we're doing.
