see who accepted a meeting in teams

[stenport]

Hi, 

I have invited a 39 people who is not in my organsation to a training seminar on TEAMS. I have invited them in a channel so I didnt put in every single email address in the meeting invitaton. Lots of people have accepted but I have no clue which ones while I didnt save the emails I got from every single one in outlook.  Isn´t it a way to see this in TEAMS??? I have looked everywhere...

This is something i'm curious about. I have a scenario where a client wants to give a book presentation to about 300 people in a studio. The goal of solution must be: "get to know who accepted the meeting to the book presentation"
