re: POP/IMAP converted to Exchange

When I open Outlook it actually says IMAP/SMTP (Swear it said POP) but now I don't see that. I have not done anything with an Exchange server. That is what I am trying to have done, I think. Basically I want my domain and email that I have purchased to be uploaded/added/converted or what ever it may need to become an Exchange account so my calendars are one in the same across all devices and that I can easily add new users as I hire employees.
