In, like most email clients, an alias is a nickname you use in your email account. In, it can be an email address or phone number. Aliases allow you to respond to different people with different email addresses from the same account. You might have an email address for work and decide to set up an alias for personal email. You may have changed your name and prefer to use it with your existing account rather than go to the bother of setting up a new account and losing your contacts and archived email.

Both addresses share the same inbox, contact list, and account settings. 

If you subscribe to Premium, Outlook can automatically filter incoming mail from each of your aliases to individual folders. With free, you have to do this manually, by clicking Move at the top of the screen of an open email to move mail from different aliases to respective folders as a way to manage your mail. 

Create an Alias Email Address in

Microsoft permits users to have up to 10 aliases on their accounts at any given time. To set up a new alias email address you can use with your mail account:

  • Go to Manage how you sign in to Microsoft.
  • Click Add email.
  • Enter a new email address to act as an alias. It can be a new address or an existing email address. It is not possible to create a new @hotmail or alias. You can also choose to use a phone number as your alias.
  • Click Add Alias.

Your primary email address is the one you used to open your Microsoft account. By default, you can sign in to your account with any of your aliases, although you can change that setting if you so choose. For example, if you go to websites that might be unsafe, you can choose to use an alias that does not have sign in privileges on your account for safety.
