Hi Michelle - Work

Thank you for reaching out to Microsoft Q&A Forum. From your description, I understand why you’d want this clarified. Please kindly note that an alias is an additional email address that’s attached to the same Microsoft account, so you can sign in with it using the same password and still access the same Outlook.com mailbox.

Here's how to add an email alias (Microsoft account):

• Sign in to your Microsoft account via https://login.live.com/
• Under Add an alias, you can choose to:
  • Create a new Outlook.com email address and add it as an alias, or
  • Add an existing email address (from another provider) as an alias.
• Select Add alias to save

Important notes:

• You can’t add an address that’s tied to a work or school account as an alias.
• Some Microsoft-owned addresses (like existing Hotmail/Live/Outlook.com) can’t be added as "existing" aliases, and an alias can’t already belong to another Microsoft account.

Just to clarify, are you trying to create a brand-new @outlook.com alias, or add an existing address (like Gmail) as the alias?

For more details, you can see this official guide here: Add or remove an email alias in Outlook.com - Microsoft Support

If I have misunderstood your situation, please don't hesitate to clarify, and I will adjust my recommendations accordingly. 

Looking forward to your reply so I can assist you further. Thank you for your understanding.

Answer 2

To add an email alias to your Microsoft 365 account, follow these steps:

1. Sign in to the Microsoft 365 admin center.
2. Go to Users > Active users.
3. Select the user you want to manage.
4. Under Aliases, select Manage username and email. (Note: This option will not be visible if the user does not have a license assigned.)
5. On the Manage username and email page, enter the new alias in the Username field, select a domain from the drop-down list, and click Add. The alias must end with a domain from the list.
6. Once finished, choose Save changes. It may take up to 24 hours for the new alias to be updated.
7. The user will now have both a primary email address and the new alias, which can be used to sign in to Outlook.com and access email.

When sending emails, the From address will depend on the Outlook client being used; Outlook on the web will use the alias that received the email, while the desktop version will use the primary email alias.
