Step by step
Check Windows system notification settings
Open the Windows Settings app by pressing Win + I. Navigate to System > Notifications and ensure the primary Notifications toggle is set to On. Scroll down the list of apps and verify that Outlook is toggled to On.
Note: Click the arrow next to the Outlook toggle to ensure banners and notification sounds are specifically enabled.Enable Outlook desktop alerts
Launch Outlook and navigate to File > Options. Select the Mail tab in the sidebar and locate the Message arrival section. Ensure the Display a Desktop Alert box is checked.
Note: If you use multiple accounts, verify this setting applies to the default data file.Disable Focus Assist or Do Not Disturb
Click the Date and Time display on your taskbar to open the Notification Center. Ensure Do Not Disturb mode is disabled. If Focus Assist is active, alerts may be suppressed during specific working hours.
Note: You can configure priority lists in Windows Settings > System > Focus if you prefer to keep alerts on for specific apps.Check Outlook Rule conflicts
Navigate to Home > Rules > Manage Rules & Alerts. Ensure no existing rules are set to move incoming mail to folders without triggering a desktop alert. Rules that move messages to subfolders often bypass the standard notification trigger.
Note: Test by creating a temporary rule that marks a message as important to see if the alert fires.Refresh the Outlook process
Close Outlook completely. Press Ctrl + Shift + Esc to open Task Manager, locate Microsoft Outlook, and select End task. Relaunch the application to force a reload of the notification service configuration.
Note: Performing a hard restart often clears stuck notification handlers in the Windows registry.
