How to Customize Outlook Calendar Alerts on Windows 11

Outlook calendar alerts are notifications designed to inform you about upcoming events, ensuring you stay on track with your schedule. On Windows 11, you have granular control over these, allowing you to tailor them precisely to your needs.

Open Outlook, click the gear icon, then General, and Notifications. Under Calendar, enable notifications and choose your preferred reminder style. Adjust Windows notification settings if alerts aren’t appearing.
