When creating a global distribution list in exchange 2003 an email address is required. When creating the same list Outlook 2003 this is not the case. For example I create a distribution list in Outlook call My distributionlist and all users receive the email from my distributionlist. On the other hand, if i create the same list on the exchange server when users receive the email it will display firstname.lastname@example.org. Why is the behavior in outlook different from that exchange. I would like to create a distribution list in exchange to behave the same way it does in Outlook without @domain.com.
