I'm concerned about something that happened with one of my users this week. He sent a message to an internal Global Address List Distribution List he created in Outlook Contacts. Immediately after he sent the message, an Out of Office message arrived from an external email address of someone he does not know. We checked his Distribution List, and the recipient was not on list at all. I'm concerned that there's something up with the GAL on the Exchange server like a trojan or worm attacking the GAL or delivery queues. I'm going to check his computer more thoroughly today for viruses or trojans. Anybody have any ideas? Thanks.

Is it possible that someone on his distribution list has configured a forwarding rule in Outlook to an external address - or - does one of the recipients on his distribution list have a forwarding address configured in AD?
Cheers

I've checked AD, and no one has a forwarding address setup there. Since email was sent to only members of our firm's partnership and the email went out to a competing firm, it just seems highly unlikely that someone has a rule setup to forward the message.

Hmmm - I agree, but you never know - how members are in the distribution list (e.g mailboxes) - you could a message track on all the members to see if it was forwarded by a rule.

OK, I've checked for the outgoing email address in the Message Tracking Center and did not find the outgoing message. I did find the incoming Out of Office response. Just to be sure the Message Tracking Center would detect an outgoing message to an outside domain, I checked for something I sent to a hotmail account that same day and found it in the MTC log.

Hmmm - odd, no outgoing message to the person that sent back in the OOO - are you sure that the OOO reply was in response to the message that the person in question had sent? - e.g. coincidence (sorry for all the questions - just trying to eliminate possibilities)

The OOO reply was a response to a meeting request, and had the request's same subject line.

Looks like I have found the answer. By using the Exchange Message Tracking Center (Exchange System Manager>(<Domain>)Exchange>Tools>Message Tracking Center), I found the forwarded message (it helps to spell the email address correctly). Thanks so much for your help and have a good evening!
