how do I access recorded meetings? when I click on the 'meetings' tab it says I don't have permission

Meeting recordings will have a direct URL, just like meeting rooms and content within Connect. You likely not a member of the Meeting Host group or Admin group within that Connect account, so you don't have the permissions to access the Meeting Library.

You will either need the Host of the meeting room that you are looking for the recording of to get you the link, and insure you have the correct permissions to view it, or have them move the recording to the Content Library where it can be placed in a folder that you have permissions to view.
