1. Sign in to the Microsoft 365 Admin Center
Sign in with your admin account credentials.
2. Find the User
In the left-hand menu, select Users → Active users.
Click the name of the user you want to add an alias for.
3. Manage Email Aliases
In the user’s profile page, click Manage username and email (sometimes shown as Email aliases).
Under Aliases, click Add an alias.
4. Add the Alias
Enter the new alias name (just the part before the “@”).
Select the correct domain from the drop-down list.
Click Add.
5. Save Changes
Once the alias appears in the list, click Save changes.
The alias will now work for receiving emails (it will deliver to the user’s primary mailbox).
Important Notes
Aliases can only receive emails — they cannot be used to sign in unless you make them the primary email address.
You can add multiple aliases for the same user.
Changes may take a few minutes to take effect.
