I have created a distribution group in windows 2007 that has a couple of exchange 2003 users in it (I am running an environment with 2003/2007). I created the distribution list on the 2007 server and when I send it e-mail internally the e-mail it works. When I send it externally I am receiving an NDR that says 5.7.1 failed. When I look at the E-mail address information the X400 information is not being populated either.
