By Impran M N
Running separate brands or campaigns doesn't have to mean juggling multiple logins. This guide covers creating a new Outlook alias, switching your default sign-in identity, sending mail from the new address, and sorting incoming alias mail into its own folder.
01Open your Microsoft account settings
Go to account.microsoft.com in your browser and sign into your primary profile.
02Access your info
Click the "Your info" tab and scroll down to find "Manage how you sign in to Microsoft."
03Verify your identity
Complete any required security check to unlock the account alias settings.
04Add a new alias
Click "Add email" under the Account Alias header, type your desired address, and confirm to add it.
05Send from your new alias
In Outlook, open a new message, click the hidden From dropdown, and select your new alias to send from that identity.
06Sort incoming alias mail
Set up a mailbox rule so mail sent to your alias lands in a dedicated folder automatically.
Frequently asked questions
Do I need a separate password for my alias?
No, aliases route into the same account, so you continue signing in with your existing primary credentials.
Can I make my alias my default sign-in identity?
Yes, you can click "Make primary" next to any verified secondary alias to change your default login identity.
Will replies to my alias come back to the same inbox?
Yes, since aliases route into your single unified mailbox, you can use a rule to sort those replies into a dedicated folder.
How many aliases can I add to one account?
Microsoft allows a limited number of aliases per account, so check your account settings for the current cap.
