How to configure Microsoft Exchange-domain\username?
Good afternoon. Vital one test exchange mail account of the form domain\login to the user connected through this option(e.g. OWA) and not firstname.lastname@example.org
Special knowledge of the subject I have, so I want to know if this functionality is to give Exchange Online, can I use the service of EXCHANGE hosting and there to deploy?
There may be more complex and need Exchange to put on top of Active Directory and then everything will be as I need.
