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

I can't find a setting to just block anyone else from adding to my calendar. I do use the calendar to keep track of things and I prefer not to delete it entirely, but I certainly don't want anyone else, especially spammers, to add to my calendar. I only found a way to block one specific email address. Not helpful. There must be a way to block everyone--but I can't find it. Please help! TIA.

1. In Outlook, go to File and then “Options.”
2. Then, select “Mail” from the Options menu.
3. In the Mail menu, choose “Tracking.”
4. Under “Tracking,” deselect the option that says, “Automatically process meeting requests and responses to meeting requests and polls.”

You're welcome.

To the Microsoft techs responding to these questions; you should find another job because you absolutely fail at this one. Setting up rules to block emails will NOT keep meeting invites from being added to your calendar if the option above is still checked.

If this works......a HUGE thank you!! This started up yesterday and every time I delete an event, another one pops up. Ridiculous!

I'm trying to follow these instructions. I'm in Outlook. But where is "File?" So I can't even do Step 1. Where are my kids when I need them? Can someone point me to where "File" is in Outlook? Thank you!

Nothing more infuriating than these instructions that NEVER match what is actually shown on the screen. Did you verify these instructions?

I'm sorry - this absolutely does NOT work.

1. It means you have to open your Outlook on a PC to apply the rule. If you open email on a non-PC device first, it does not process your rule.
2. It only moves the email into your spam or deleted folder - whichever you select. To actually remove the event, you then have to delete the email from spam/junk folder, AND empty your trash email. Not really practical when getting 20-30 of these events per day.

Microsoft - give me an option to just BLOCK all connection from email to my calendar. period. EASY!!!
