How do I block random people adding meetings to my calendar?

This is the most ridiculous suggestion to stop spam events from being added to my calendar, especially ones that won't let me decline the invite. This is irrelevant as they are coming from accounts we don't know. Just a heads up, I have followed your instructions and made a rule, but it doesn't remove a calendar invite that the sender has set up so it can't be declined/deleted.

For a tech company, I would have thought internet security would have been a high priority and that you would be putting measures in place to prevent it from happening, rather than an afterthought of how to stop that same sender from adding us to a future event. It's no wonder people are moving away from Hotmail/Microsoft emails. My only solution now seems to be to close this email address and move to another company's email instead.

MICROSOFT, ARE YOU LISTENING ??????????????????

It should be real simple to stop folks from making unwanted spam appointments on Calendar. The default setting should not allow anyone to put spam on our calendar. Microsoft has been writing code longer than anyone and you can't do this one simple task? Are you reading this ?? I guess not. I have your premium account and get more spam in my "Focused Mail Account" than real mail. Gmail has zero spam!

I have looked under every heading and every pull down for the past hour logged in on a Desktop app and do not see anything related to Tracking to uncheck. If there is an option why do you make it so difficult to find. It appears 3000 other folks that have view this topic because they are having the same issue.

I sooooo agree with CH .,.. i am getting VERY angry that this issue is still happening!!!
Open my agenda... i use it for my 3 businesses.... and spending so much time every time to just delete SPAM appointments that have bene set in my agenda.... WTH Microsoft !!!
As a business we are "this close" to cancel all Office 365 etc etc etc ...

Microsoft, I am another dissatisfied and disappointed user with the same undesired calendar invitations issue. Obviously this problem is pervasive and long standing. It is incomprehensible why you refuse to provide a functional solution.

My phone won’t allow me to just delete the message and the invite isn’t in my email. I have to cut (as if I’m going to paste it somewhere else) each one twice to get rid of it but the first one sent a response. Now my calendar is flooded with spam.
