Using classic Outlook for Windows in business environments
Hi,
My name is Cindy. I am sorry you are having this problem. I know it is really frustrating. I will do my best to help you with this problem.

It is possible to stop the Windows pop-up notification by clicking on Settings > System > Notifications & Actions and turning off the notifications you do not want to see.
Please let me know if you have any questions.
Best Wishes,
Cindy
