An Adobe Connect meeting room lasts forever until the meeting creator deletes it (meeting creators: see Editing and Deleting Meetings under Creating/Editing Meetings for details). However, Hosts do have the ability to end a meeting, place it on hold, or block incoming attendees.
For all users, to exit a meeting without closing the meeting room, see Joining/Leaving a Meeting under Getting Started.
Ending a Meeting
Hosts can select to end a meeting, which removes everyone from the meeting room and locks the room until a Host re-enters. All users, including the Hosts, will be removed from the room.
To end a meeting, from inside the meeting room click the "Meeting" menu on the top menu bar and select "End Meeting." The Host can set the message that is posted to all Attendees when they are removed from the room. The Host can also set a URL to send the Attendees to in addition to setting an end-of-meeting message. The URL will open a browser window on all Attendees' computers, covering, and possibly obscuring, the end-of-meeting screen displayed by Adobe Connect.
To re-open the meeting, a Host must go into the meeting room and click the "Start Meeting" button. When re-starting a meeting, if the Host doesn't de-select the box to "Lock the meeting after starting," Attendees will have to wait for a Host to allow them to enter the room when they try to re-enter. Unchecking the box will allow Attendees to re-enter the room as usual, depending on the access setting for the room.
If a Host ends a meeting and then re-opens the room, Attendees who were removed from the room do not receive any notice that the room has re-opened.
Placing Participants on Hold
Hosts can temporarily place Participants on hold, which prevents Participants from seeing what is happening in the meeting room without actually removing them from the room. Hosts and Presenters continue to have standard access to the room that has been placed on hold.
To place a meeting on hold, from inside the meeting room click the "Meeting" menu on the top menu bar and select "Manage Access & Entry">"Place Participants on Hold."
To re-open the meeting room to Participants, a Host must de-select "Place Participants on Hold" from inside the meeting room. Participants who were locked out (but still kept the meeting window open) will automatically be let back into the room.

Closing or Pausing a Meeting
Blocking Incoming Attendees
Hosts can block incoming attendees so that no new attendees can enter the meeting room. All incoming attendees, including those on the Current Participants list and those who leave and re-enter the room, will be blocked from entering.

Block Incoming Attendees
While access to the room is blocked, Hosts can allow incoming attendees to request entry. When an incoming attendee requests entry, Hosts can allow or deny the request. Note that attendees who are denied entry can simply keep trying to re-enter the room and request entry again.
To stop blocking entry, de-select the option from the Meeting menu.
Although there is also an option in the Meeting Menu> Manage Access & Entry menu to block guest access, Penn State doesn't allow unregistered guests in meetings, so selecting this option will have no effect on meeting room access.
