Update my email settings to Exchange in Mail on Windows

If you migrated a POP or IMAP email account to Microsoft 365, export your previous locally saved data and set up your new account with Exchange settings. Using Exchange ensures your data — including mail, contacts and calendars — stays connected with your email and is recoverable from the server whenever needed.

1. Open Mail.
   
2. Select Settings, and then Manage accounts.
3. Select Add account.
4. Select Office 365.
   
5. Enter your Email address, and then select Next.
6. If asked, select Work or school account, and then Continue.
   
7. Enter your Password, and then select Sign In.
Note: If after trying to sign in, you see Something went wrong, select Advanced. Then enter the following:

• User name: Your email address.
• Domain: The name after the @.
• Server: outlook.office365.com
• Account name: This is only visible to you and can help identify the account.
Note: If you forgot your email password, reset it.
8. If your admin enabled multi-factor authentication (MFA), verify your account or set up the Authenticator app.
9. You might need to choose if you want Windows to remember your account, or if you only want to sign in to the Mail app.
10. You'll see confirmation when your account is set up. Select Done. Your Exchange account will be added. Make sure that all your data is in the new Exchange account, and if anything is missing, keep both accounts until you've recovered your missing data. If everything looks good, you're ready to delete the POP/IMAP account.
11. Under Manage accounts, select the POP/IMAP account.
12. Select Delete account, and then Delete to confirm.
    

All done! Your email is set up on the Exchange server.
