How to turn off Outlook notifications
Microsoft Outlook can be a good program for managing emails but its desktop notification system can be annoying, rather than useful.
While most users would rather keep those notifications on, there’s an easy way to turn them off. Simply head down to the Outlook notification in the lower right-hand corner of the screen, and check the “show new mail desktop alert” button.
If you want to turn them back on, just head to that menu and click the button again.
