Add my Microsoft 365 email to Mail on Windows

Step 3 of the Set up my Microsoft 365 account series.

Add your Microsoft 365 account to the Mail app for Windows so you can send and receive email.

Note: Windows Mail, Calendar and People is transitioning to Outlook. Access to the new Outlook requires a Microsoft Office license, either via a Business Professional plan (or higher) with us or from another provider. If you’re using the new Outlook, these steps may vary. Learn more about the new Outlook for Windows from Microsoft.
