How change name to emails sent out the outlook.com account, not Microsoft Outlook

I downloaded external mail software (Outlook) where I could easily connect to both my email addresses and move email from one account to the other by drag & dropping the folders/emails.

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!
