Control Outlook Alerts When App Is Closed
Outlook pop-ups for new emails and calendar reminders continue to appear in Windows even after you close the app window. Microsoft builds this background feature into the new Outlook for Windows so you stay updated without leaving the main program running all day.
Stopping these alerts removes daily distractions and saves a little battery power on laptops. You can turn off background notifications in less than two minutes through the Windows settings menu.
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
You can turn Outlook notifications when closed on or off by opening your app settings and toggling the background alert option. Managing this setting lets you choose whether you want to see new message pop-ups even when the main mail window is shut. Follow the steps below to change this preference in your account right now.
Here is how to configure the feature.
1. Open Outlook from the Start menu or taskbar search box .

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

3. Select General in the sidebar, then open Notification settings.

4. 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.

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

7. 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.
Disabling background notifications stops distractions and saves system resources, while keeping them on ensures you never miss urgent messages.
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.
