Over the weekend I received two obvious spam email that I immediately deleted. After a couple of nights of late night meeting reminders. I discovered the tentative meeting invites in my calendar from the emails I deleted. every day for the next year (or at least that is as far as I checked). Up until this point I never even heard of email spam. I don't actually use the calendar feature in outlook. I have been very careful not to click on any of the links in the invite. When I hover over the meeting and the Outlook calendar options menu opens the "Delete Meeting" & "Delete Series" links are not active.
Very simple how can I delete the messages or How can I disable the calendar features?
