I know this should be easy, however it does not work and I cannot find a solution. Hopefully someone here can help.I want to send e-mail to a distribution list that contains a custom recipient. This CR is configured with an external address. If I send directly to the CR, the e-mail goes fine. If I send to the DL which contains the CR, thee-mail stops at 'Message Submitted to Categorizer' (as seen via message tracking). I cannot find the message in any queue - it just dissapears. I have all options checked on the Global Settings / Internet Message Formats option. Meaning - the options for 'Allow out of office responses', 'Allow automatic replies', 'Allow automatic forward', etc have all been checked. We are using Exchange 2003 SP1.I am at my wits end here. Any help would be greatly appreciated. Thank you very much.DAN

Dan, The first thing I thought of was to ask you why you are still running E2K3 SP1. SP2 has been out for years. Not that this is a known issue or anything, but I was just curious. Anywho.... do you have more than one Active Directory domain? If so, maybe the contact exists in a different domain that the Exchange server is using to enumerate the group membership? Try converting the distribution group to a universal distribution group.If you are in a single domain, try increasing the diagnostics logging categories for the Categorizer (if I remember correctly, this is on the MSExchangeTransport section of the Diagnostics Logging tab of the server's properties.HTH,Jim McBeeJim McBee - Blog - http://mostlyexchange.blogspot.com

Jim - thank you so much for the reply. You are right on all accounts.I went back and checked and we are running SP2. Sorry for the mis-q. And yes - you are right about the Universal / Global aspects of the DL. I had found another post somewhere else that mentioned that and I tested an hour ago and things started working. Thanks so much for the info. This was very helpful - I appreciate all your input. Thanks again. DAN
