There are many different types of email and collaboration resources available in Office365, and they each have their own functions and use cases. This page is intended to help you determine which type you need before you submit a request for one to I.T.
Distribution List - A Distribution List (DL) is a grouping of mail users under one email address. When an email is sent to the address of the DL, every member of the DL gets a copy of that email in their own mailbox. DLs can only be used to receive mail; the address of a DL cannot be used as the From address to send mail.
