Provide ability to remove users added to recurring meetings' chats
We have the following scenario that cannot be remedied without deleting a recurring meeting:
1. User A and B have a recurring weekly meeting in Teams.
2. User C is invited to join the call on this meeting during one instance.
3. Even though User C has not been invited to the recurring meeting, User C now has access to the Teams chat of the subsequent recurring meeting instances.
This seems like a huge bug that you cannot remove a user from seeing the chat of a meeting to which they are normally not a member. I just spoke with Microsoft support and their recommended course of action is to delete the recurring meeting and re-create it, losing the chat history.

You can manually remove a user but easily overlooked. Better to set it up so that if someone is invited to a single occurrence of the meeting they are automatically removed from the chat at the end of the meeting
This looks to have been addressed. If you find the meeting in your chat history, you will see the view and add participants button in the top right hand corner with a count of participants. Clicking this will give you a popup menu with a list of people, that have been in the meeting. Click the x next to the person you wish to remove. A warning message identifies that they will see the chat history (but presumably not new messages).
I have not found a way to do this through the calendar for recurring meetings only chat history.
This is creating security risks. For example, if I invite an employee to present project status at a managers' meeting, then that employee can continue to see chat threads of future managers. meetings, where confidential information may be exposed.

@Howard, It does look like you can remove a guest, but not any user who has credentials from within the org.
Still a big hole because, let's say you have invited someone as a guest presenter, but then want to discuss their presentation on subsequent calls. This person continues to have a view on the discussion, even at times you would prefer to keep it private.
this is very annoying when I am invited to a recurring meeting, never attend, but still get chat history and unread threads that I have to clear :(

In addition to being a management annoyance with regular meetings, this is a potentially significant security hole. There is no indication that someone added once to an established meeting will continue to have access to all future occurrences of that meeting. Thus this could be an unmonitored window into conversations that are otherwise assumed to be secure. Take this example:
1) An organisation has a regular internal weekly meeting.
2) An external consultant is invited into the meeting once for a particular discussion.
3) This consultant now has access to all future occurrences of the meeting, potentially in an undetectable way if they audit those meetings silently.
Until this addressed, this hole significantly compromises the usability of Teams in a professional setting, and may even lead to violations of corporate, national, or international privacy regulations under some circumstances.
