In Outlook.com, like most email clients, an alias is a nickname you use in your email account. In Outlook.com, 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 @outlook.com 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 Outlook.com Premium, Outlook can automatically filter incoming mail from each of your aliases to individual folders. With free Outlook.com, 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 Outlook.com Alias Email Address

You sign in to Outlook.com using your Microsoft credentials. Microsoft permits users to have up to 10 aliases on their accounts at any given time, and you can use any of them to work in Outlook.com. To set up a new Microsoft alias email address you can use with your Outlook.com mail account:

  1. Sign in to the Microsoft account website.
  2. Click Your info.
  3. Select Manage your sign-in email or phone number.
  4. If you use two-factor authentication, request and enter the necessary code before going to the Manage how you sign in to Microsoft screen.
  5. Enter a new email address to act as an alias. It can be a new @outlook.com address or an existing email address. It is not possible to create a new @hotmail or @live.com alias. You can also choose to use a phone number as your alias.
  6. Click Add Alias.

Your primary Outlook.com 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.

About Microsoft Aliases

All of your Microsoft aliases share the same Outlook.com inbox, contact list, password, and account settings as your primary alias, although some of this can be changed. You can opt to turn off the sign-in privileges of an alias you hand out to strangers to protect your information. Other notes:

  • You cannot use an existing @hotmail.com, @live.com, @outlook.com, or @msn.com address as an alias.
  • You cannot add an alias that is already associated with another Microsoft account.
  • You can change which of your aliases is your primary alias at any time.

Considerations When Removing an Alias

You remove an alias from your account in the same place you added it. 

  1. Sign in to the Microsoft account website.
  2. Click Your info.
  3. Select Manage your sign-in email or phone number.
  4. In the Manage how you sign in to Microsoft screen, click Remove next to the alias you are removing from your account.

Removing an alias does not prevent it from being used again. To completely delete an alias, you have to close your Microsoft account, which means you lose access to your inbox. The conditions surrounding the reuse of an alias vary as follows:

  • If the alias you remove was an email address from a non-Microsoft domain (such as @gmail.com), it is available to be added as an alias on another Microsoft account immediately.
  • If the alias you remove is an email address from @outlook.com, it can be recreated as a new account or alias after a 30-day waiting period.
  • Email addresses from @hotmail.com, @live.com, or @msn.com cannot be added again as an alias to any Microsoft account after they are removed.
