Control Outlook Alerts When App is Closed
Outlook notifications running when the app is closed mean you still see pop-ups for new emails and meeting reminders even after you shut the program. Microsoft includes this background feature in the redesigned Outlook for Windows to keep you updated without keeping the full app open all day.
Turning on these alerts helps you catch urgent messages right away. Turning them off stops distractions and saves computer battery.
Open Outlook, click the Settings gear, select General, then Notifications. Find “Notifications in Outlook” and check “Send notifications when Outlook is closed” to enable alerts. Uncheck it to disable them.
Turn “Send notifications when Outlook is closed” on or off
Outlook allows you to control alert visibility while the application sits closed in the background. Deciding whether to receive these messages helps balance staying informed with reducing daily interruptions.
Here is how to configure the feature.
Launch Outlook from your Start menu or taskbar search box .

Click the Settings gear icon at the top right of the menu bar.

Select General in the sidebar, then open Notification settings.

Locate the 'Notifications in Outlook' section. Click the dropdown caret to reveal sound controls for your alerts.
(This assumes you have "Notification in Outlook" turned on.) Inactive main notifications render the nested settings ineffective.

Check the box next to "Send notifications when Outlook is closed" to keep receiving alerts while the application remains shut down.
Uncheck the box to halt background alerts.

Close the window when finished.
Troubleshooting missing alerts requires checking your Windows Notification settings, ensuring Focus Assist (built-in distraction blocking) remains disabled, and turning off Battery Saver.
That completes the setup process.
Conclusion:
- Enabling or disabling notifications when Outlook is closed on Windows 11 can help you manage your productivity and stay updated on important emails and appointments.
- The option to receive notifications when the app is closed provides the convenience of staying informed without actively using the Outlook app.
- Conversely, based on personal preferences and work style, disabling this feature can help minimize distractions and conserve system resources.
- Following the outlined steps, you can easily configure this setting to suit your needs and enhance your Outlook experience on Windows 11.

Too bad Outlook won’t save ‘Notifications When Closed’. It’s listed as an option but is non-functional. Simply put, Outlook (Win11) does not send notifications when closed… Which is uselessly substandard.
