What do I need to discover users and distribution lists from Exchange 2007+?
In order to discover users, distribution lists, and aliases from Exchange 2007+ :
- On the Email Administrative Credentials page, select the options for user discovery, and/or distribution list discovery.
- Provide an Admin email address. This must be a mailbox enabled administrator, and in a "firstname.lastname@example.org" format.
