How to Set Outlook as the Default Email App in Windows 11
Question details
The user needs to configure Windows 11 to use Microsoft Outlook as the default email application for handling mailto links and email-related file types.
- Product
- Microsoft Outlook
- Device & OS
- Windows 11
- Scenario
- Clicking on email links opens the default Windows Mail app instead of Microsoft Outlook.
- Observed behavior
- Email links and specific file protocols bypass Outlook and automatically open in the built-in Windows Mail application.
Ensure that Microsoft Outlook is fully installed and your Office suite is updated to the latest version on your Windows 11 PC before attempting to change the default application settings.
Set Outlook as Default via Windows Settings
Use the Windows 11 Default Apps settings menu to manually assign Outlook as the primary handler for all email protocols and file types.
This is the most direct method to ensure Windows routes all email-related clicks to Microsoft Outlook rather than the default Mail app.
Press the Windows key + I on your keyboard, or click the Start button and select the gear icon to open the Settings app.
Click on 'Apps' in the left-hand sidebar, then select 'Default apps' from the list of options on the right.
Scroll down the list of applications or use the search bar at the top to locate 'Outlook', then click on it to open its specific settings.
Locate protocols such as 'MAILTO' and file types like '.eml'. Click on the currently assigned app (like Windows Mail) and select 'Outlook' from the pop-up menu to set it as the new default.
Repair Microsoft Office Installation
If Outlook is missing from the Default Apps list, repairing the Office suite can restore the necessary registry keys and application handlers.
Create a New Outlook Profile
Creating a fresh Outlook profile can resolve underlying configuration issues preventing Outlook from registering as the default mail client.

Frequently Asked Questions
Why isn't Outlook showing up in my Windows 11 Default Apps list?
Outlook might not appear if the Office installation is corrupted, outdated, or incomplete. Running an Online Repair for Microsoft Office from the Settings > Apps > Installed apps menu usually restores the missing application entries to the Default Apps list.
What is the MAILTO protocol and why does it matter?
The MAILTO protocol is a specific rule that tells Windows which application to launch when you click on an email address link on a website or inside a document. Setting Outlook as the default for the MAILTO protocol ensures these links open directly in an Outlook compose window.
Can I set 'Outlook on the web' as my default email app in Windows 11?
Yes. If you use Microsoft Edge or Google Chrome, you can log in to Outlook on the web, install it as a Progressive Web App (PWA) via the browser's address bar icon, and then select this PWA in the Windows Default Apps settings to handle email links.
