When one invitee cancels a meeting , it canceled the invite for everyone

[Lansend]

A client is  having a recurring issue with an Outlook invite sent once per month.
It is an Outlook calendar invite with a Zoom meeting and it is sent to about 100 people.
This month and a few months ago one of the people invited to the meeting 'cancelled' it and it cancelled the invite for everyone. I'm not sure how this is possible since client is the organizer, any help with this would be great!

Apologies ,It has now been brought to our attention , that it is the Outlook invite that gets canceled and not the Zoom meeting,

Hi @Lansend thank you for posting to the community! 

If I'm understanding correctly, this seems to be an issue on the Outlook side correct? If so, please let us know if there is anything we can do to help on our end!
