Creating Reusable Teams Meeting

here are my answer to your questions:

1. Teams Meeting Link Reusability:
   Unlike Zoom, Microsoft Teams doesn’t officially offer the feature to create a permanent meeting room. Each Teams meeting creates its own space, so later attendees can see the names and conversations of earlier attendees if the same link is used.

2. Duration of Meetings:
   Microsoft Teams allows you to host online meetings and video calls for up to 300 people. There’s no specific limit on the length of a single meeting.

3. Removing a Guest After Organizer Leaves:
   Teams don't currently have a feature that automatically removes all participants when the meeting organizer leaves. However, the organizer can manually end the meeting for all participants.

4. Organizer Notification When Someone Joins:
   Teams don’t currently have a feature that notifies only the organizer when someone joins the meeting. However, you can enable the Lobby function for everyone, which will notify you when someone wants to join the meeting.
