Scheduling and managing events using Outlook.com calendar
@Barbara Sandretti said
How do I get rid of these pop-up events?
If you've been targeted by a Spammer using Spam Calendar Events - I am sorry, but there is not anything you can do if you are using a personal Microsoft account.
This is a know issue. Microsoft is aware of the problem but there is currently no fix. Unless you are in an IT Managed Environment there is nothing you can do to stop them.
