Why am I suddenly receiving spam calendar invitations/appointments in Outlook (Microsoft 365 Family).

It is mind blowing that MS won't fix this issue. I have had this problem for a long time now and tried all the suggestions in this post and nothing work or stops the invites from automatically being added to my calendar.

There is no excuse for not fixing this.

I am paying for Office 365 but they are not delivering.

Has anyone tried a alternative to MS office and email that works well as a replacement?

None of these suggestions fixes the problem. Not efficient to be playing whack a mole

Will need to switch to other email. Also I do have a paid subscription to office 365, so this is a Microsoft weakness

They don’t care. My money is in their bank

LibreOffice + Thunderbird (with GcalTab extension if desired)

So far I have not received any calendar invites since I made the changes in the Tracking Section. The only item I do have checked is "Automatically update original sent item with Receipt information". This seems to have worked for me.

In the Calendar Section, I do not have any items checked under "Automatically accept or decline requests".

I changed these setting forever ago and still get them all added to my calendar then it blows up with alerts for events. I now have hundreds. If I opted out this should not be happening. Is microsoft going to fix this or what.
