To configure Microsoft Outlook (Desktop Client) to trigger desktop notifications for emails that are automatically moved to a subfolder (e.g., Inbox > alerts) using a mail rule.
By default, Microsoft Outlook Desktop only generates desktop alerts for emails delivered to the main Inbox folder.
When a rule moves emails directly to a subfolder (e.g., alerts), desktop notifications are not triggered unless explicitly configured in the rule.
Modify the existing mail rule to include the Display a Desktop Alert action.
Open Microsoft Outlook Desktop
Navigate to:
File → Manage Rules & Alerts
Select the rule that moves emails to the alerts folder
Click:
Change Rule → Edit Rule Settings
Click Next until you reach the section:
"What do you want to do with the message?"
Check:
✅ Display a Desktop Alert
Also, you can enable ✅ Play a sound for notification sounds, but it is optional
You have to select a Tone for that by clicking in the blue underlined Sound option
Here you can select any kind of Tones (Message tones, Ringtones etc..), by default there are so many Tones available. Also, you can add new one, but it should be a WAV file.
Then you can choose a Tone for this notification
Click Next → Click Finish → Click Apply → Click OK
Verify global Outlook notification settings:
Go to:
File → Options → Mail
Under Message arrival, ensure:
✅ Display a Desktop Alert is enabled
Also verify Windows notification settings:
Settings → System → Notifications
Ensure Outlook notifications are enabled.
