Update :- The registration link was disable by Microsoft.
Previously, we look at on “How to Register @live.* / @hotmail.* / @outlook.* e-mail Address“.
However, if you are not happy with the available domain selection, there is another nice domain offered by Microsoft. They are offering @msn.com email address as well. Unfortunately, there is no way you can find to a way to register this from their website.
I think @msn.com is a very nice and short email address. The domain is only three (3) characters contrary to at least four (4) characters with live.* email address. This email is also part of Windows Live.
If you’re interested to register this email address kindly use the following secret link.
