We are migrating from a hosted Exchange service to Office 365 E1 and E3 licenses. We have a large number (1,700+) of white list, or as Forefront? calls them, "safe senders".
Our list contains domain-wide entries such as *@domain.com, as well as full simple user.name@live.com entries.
Three questions:
- What file format do we request export of our old white list from our prior Exchange host for import to Forefront or for import to our domain-wide admin on Office 365?
- What is the procedure for this sort of import?
- Does each user have to import it it separately? Or can a Global Admin import once covering all users at our domain?
(We don't have our own Exchange server, only the Microsoft Online one.)
thank you,
Eric
