Hi
@Crizel1207,
If you are not the meeting organizer and you forward a meeting to someone that was not originally invited to the meeting, Outlook sends a meeting forward notification to the meeting organizer. The existing meeting attendees are not notified about the added attendee.
However if the goal is to hide the attendees' list, you have to schedule the teams meeting this way:
https://www.thewindowsclub.com/hide-attendee-list-outlook where you need to enable "Hide attendee list" option. When the recipients accept the request and join the meeting, they won’t be able to see other recipients’ names.
