Microsoft Live Custom Domains are now shutting down. I have been using this service for e-mail hosting for all my Microsoft Azure Websites, but now it is gone and no viable repl
How many real people do you have reading e-mail? As many as you got mailboxes? If not, then I really suggest you go for Exchange Online from Microsoft which goes for $4 per user (not mailbox) per month.
The trick is, that once you've set up your domains, you create a Shared Mailbox
through PowerShell and while doing so, you give the real people (you pay for) the rights to read and send as
. The cool thing is, that the user does not need to do anything. The mailbox simply appears in their Outlook.
