We are in the process of migrating to Exchange 2010. We have an email address in our old system that is a distribution list. In Outlook, in order to send from that email address, we have to setup a second account and set the email address to that distribution list's email address. The actual account settings for that second account would just be the same as the person's primary email account but that second account is removed from the Send/Receive list.
In Exchange, we want similar behavior. We want an email address that is a distribution group. We have that part done in Exchange. It is desired that each member of that distribution group be allowed to choose the distribution group's email address as the From address in their Outlook client. Is that possible or do we need to rethink how we do this? I know you can use the "Send As" option for mailboxes but that doesn't appear to be an option for distribution groups.
