Notes

• If sign-in fails, verify your credentials by logging into https://outlook.office.com first
• Some older versions of the Mail app may prompt for additional server settings - if so, contact Twilight I.T. for assistance
• Microsoft is gradually replacing the Windows Mail app with the new Outlook app, so this interface may change over time
