Hi,

I am afraid this is an ongoing problem and you cannot do much in this case.

Via HornBlower's post here:

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.

Possible Workarounds (IT Managed Environment)

If your organization has a Microsoft Defender for Office 365 subscription, there are steps you can take to mitigate the impact:

If you are in an IT Managed environment there are Mail Flow Rules that your IT Admin can implement that will block all external Calendar invites (and allow for specific exceptions):
