Setting a default From address in Outlook for Windows makes your preferred email account send every new message automatically. This built-in setting stops you from sending work or personal emails from the wrong inbox by accident.

The new Outlook app on Windows 11 lets you pick one main sender address for all outgoing mail. Pinning down a primary email stops a messy daily habit and keeps your inbox organized.

⚡ Quick Answer

Change your default sending address by going to File, then Account Settings, and selecting Account Settings again. Choose the email account you want as your default and click Set as Default.
