How to get notifications to appear on all screens?

Check three areas in Windows 11 to get notifications showing visually again, not just sounding.

1. Confirm notifications are enabled system-wide
   1. Open Settings → System → Notifications & actions.
   2. Make sure Get notifications from apps and other senders is set to On.
   3. Under that, for each important app (Mail, Calendar, Outlook, etc.), select it and ensure:
      • Notifications is On.
      • Show notification banners is On.
      • Show notifications in action center is On.
      • Optionally, Allow notifications to play sounds is On if sound is needed.
2. Turn off Do Not Disturb / Focus assist / Quiet hours
   If Focus assist (Quiet hours) is on, notifications won’t appear on screen, even though sounds or some exceptions may still occur.
   • Open Settings → System → Notifications.
   • Turn Do Not Disturb / Focus assist off.
   • Also check any automatic rules (during certain hours, when duplicating display, etc.) and disable them if they are hiding notifications.
     When Quiet hours/Focus assist is enabled, Windows won’t show app, email, or calendar banners in the corner.
3. Check the notification center behavior
   Even if banners disappear quickly, notifications should still collect in the notification center:
   • Select the time/date area on the taskbar to open the notification center.
   • From there, notifications can be expanded, acted on, or cleared.
   • In that panel, for any notification, select the settings button and confirm it isn’t set to Turn off all notifications for that app.

If the issue is only with Outlook.com (web mail) notifications in a browser, also verify inside Outlook.com:

1. Go to Settings → General → Notifications.
2. Under Mail and Calendar, set toggles to On and choose to show reminders as pop-up notifications.
