Microsoft Email – Why Live.com Domain Creation is Not Possible

There is no difference. Just use the one that you prefer, if the address you want is still available.

Hotmail has 364 million users. They started adding more domains so that more people could get the email address they wanted. My mother managed to find her name available on @hotmail.co.uk, while she has to have a large number as a suffix on @hotmail.com.

If you have your own domain, you can use it on Hotmail, while still being able to use the domain for websites.

It is possible to set up an alias for your email address in the country code top level domain. The option is available somewhere in the mail settings. Here are some steps (note that this is using Outlook online):

1. Log in to your Hotmail/Windows Live account.
2. Click on the gear icon on the top right hand corner and select "More mail settings"
3. In the Options page, click on "Your email accounts" under the "Managing your account" header.
4. In the new page, you will see the "Create an Outlook alias" heading, as shown below:
5. Click on that button and you would be able to walk through the creation of an alias in your preferred domain (depending on availability of the email address).

Hope this helps!
