Have a distribution list that forwards email to internal and external contacts?
Using the distribution list feature, you can create an email address that will forward email to one or more Exchange mailboxes as well as forwarding email to one or more Global Contacts! After adding a member to your Global Address List, the contact will be assigned an email address within your domain. This allows you to add them to any distribution list that you want to create. For example you can create a distribution list like consultants@your-company.com that forwards email to sally.jones@your-company.com (an Exchange User) and jon.doe@your-company.com (a Global Contact with external email address jondoe2001@some-isp.com). So any email sent to the “Consultants” distribution list will arrive in Sally’s Exchange mailbox and Jon’s external ISP mailbox.
