How to Set Default From Address in Outlook for Windows
Setting the default ‘From’ address in Outlook for Windows lets you choose which of your email accounts sends messages automatically.
This simple setting ensures your emails go out from the correct account without you having to pick it each time you start a new message.
It’s super handy if you manage multiple email addresses, like one for work and another for personal use. The new Outlook app on Windows 11, which replaces older apps, supports accounts like Microsoft 365, Outlook.com, Hotmail, and Gmail.
Picking a default ‘From’ address saves you time and prevents mistakes, especially when you’re sending emails for different purposes.
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.
Set default From address
You can set your default ‘From’ address in Outlook so it automatically picks your preferred email account when you start a new message. This saves you time and streamlines your email sending process. Follow these steps to set your default sender address in the Outlook app.
This article shows you how to configure your Outlook app to set the default From address. The steps below outline how to achieve that.
First, open the new Outlook app on Windows 11. You can find it by clicking Start -> All apps -> Outlook, or by searching for ‘Outlook’ in the Start menu search box.
Once the app is open, click the Settings button (that’s the gear icon in the top right corner) to continue.

On the Settings page, navigate to the Mail tab in the left sidebar and then select Sync mail on the right.

Next, choose the email address you want to designate as your default ‘From’ address.

If you don’t see multiple addresses listed, you’ll need to set up aliases first. Learn how to create multiple email aliases in your Microsoft account through the linked post.
