In addition to the great advice from Hunter, you might want to check your virus definitions are up to date and that your Exchange-aware AV software is working properly.
Exchange 2003 loop detection is pretty good in most cases, but it won't pick up everything. For example, badly configured Inbox rules can cause problems: my rule forwards emails to your mailbox and your rule forwards mail back to my mailbox. As Hunter suggests, a good way to counter problems like this is to configure mailbox limits for all mailboxes. Also configure your monitoring software to detect rapid store and transaction log growth. With any luck you can catch the problem while it's in progress, which will make troubleshooting easier.

Did you have mailbox limits configured? As for finding the cause, in ESM go down to one of the bloated stores and sort the list of mailboxes based on size. Pick a couple of the largest ones and go into the Message Tracking Center, then look for messages delivered to those mailboxes during the time that the stores grew. This will give you a place to start looking, and message loops are a likely candidate. If none of the mailboxes show up as being excessively large, you'll need to start poking around the message tracking logs directly. You could also set up LogParser to analyze the message tracking logs. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Douglas M.

Not the Exchange databases? An offline defrag is needed to reduce the size of the store? -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Brett Shirley Sent: Friday, August 12, 2005 2:06 PM To: [email protected] Subject: Re: [ActiveDir] OT:Exchange 2003 SP1 bloat If it is just one mailbox store, you can bet it is a specific user that is causing the problem (not that it is the users' fault or intention). Some message for that person being wedged, or something ... Any Mac user's with Entourage? There was an issue there once upon a time. http://blogs.msdn.com/jeremyk/archive/2004/11/11/255705.aspx http://www.e2ksecurity.com/archives/001308.html Ah, here's teh official one, I think: http://support.microsoft.com/?kbid=889525 Cheers, -BrettSh On Fri, 12 Aug 2005, Douglas M.
