Microsoft just revealed the preview of its latest incarnation of Webmail, Outlook.com. One particular Outlook.com feature worth noting, is its support of multiple e-mail aliases. They're a great way to protect your primary e-mail address. And because you can't log in to your Outlook.com account with an alias, it adds another level of security.
How To Add an alias
To add a new alias to your primary Outlook.com account, click on the gears icon in the upper right-hand corner and select "More mail settings." Under the "Manage your account" section, select "Create a Outlook alias." Type the alias you want to add and choose among the outlook.com, hotmail.com, and live.com domains.
Use your alias:.
To send an e-mail as your alias, click on your account name, just above the To: field, then select the alias you want to use.
That's it. If Outlook.com follows Hotmail's alias guidelines, you'll be allowed to add five aliases per year, but no more than 15 total.check out Our take on Outlook: Top 10 features
