Meeting Tampering and protection

[Xee9003]

I have a colleague tampering with my Zoom Meetings. How do I stop it?

I don't even get messages that the meetings have been moved on the calendar. 

Not sure as to how that happens.

Is there a way to protect meetings?

Any advice?

Welcome to the Zoom Community, @Xee9003.

This normally can only happen under two scenarios that I can think of:

1. The other person is an Owner or Admin on the organizational account.
2. You have extended Scheduling Privileges to each other, which allows you to schedule and start meetings on each other's behalf, and also to change the ownership of a meeting between the two of you.

Are these meetings being changed with in Zoom?  Or are they moving on an external calendar?  Zoom doesn't control the calendar, so if the meeting is being moved on the calendar, please contact your IT department and ask for more security on your account.
