We have an enterprise Zoom account with licensed users. Currently, our meeting's will time out after 40 minutes if only one person is present in the call. 

Is it possible to lower this limit? We have a use-case where we want a meeting to end after 5 minutes if there is only one participant. 

A meeting registrant insists that he couldn't join a meeting because zoom never sent him a registration approval email (the email that contains the meeting join link, id and passcode), and he is asking for proof that zoom sent one to his email address. Where can I find email tracking receipts of zoom emails to meeting registrants?

This is another Mac vs PC issue with zoom.

I've noticed, that when I Screen Share on my Mac, it automatically defaults to sharing my Desktop Screen versus the last application opened.  So if I wanted for it to open automatically on my powerpoint slides, i have to flip around and find it. 

Not a big deal.  But annoying.  And can look a little disorganized when you share.

Anyone encounter this and have a suggestion on how to configure so zoom will open up on a particular application or file when you share?

Based on the thread below, this is expected behavior, but it it seems to me that users should have a choice.

I would prefer there to be an option that Zoom, like the vast majority of Windows programs, only go full screen to the point where the taskbar starts. Instead, it covers the taskbar, which makes multitasking during Zoom calls to be incredibly painful. Windows 10 does not show the taskbar area, volume, and notifications area on anything but the main monitor. So if I want to have my Zoom meetings fullscreen on my primary monitor (where my camera is also located), I have to switch Zoom to windowed mode just to access the aforementioned areas on the taskbar.

Is there any way around this, or am I forced to keep Zoom in windowed mode?

Today, I was taking class and I had to share screen (a video) from my tablet. When I started sharing the video, and pressed play, automatically,  I couldn't hear the other participants anymore, which is a a problem because my teacher was talking, but I couldn't hear a thing or take notes.

How can I solve this?, how can I be able to share a video from my tablet, but still hearing other participants?

I hope you can help me. Thanks

Using macOS Monterey 12.3.1 and Zoom 5.10.1.

Using a mic plugged into the mac works fine and identified in both mac sound settings and in Zoom audio dropdown. It works for about 1 second, then switches to the built in mac microphone, but no change shown Zoom's drop down. 

Latest Mac update might have trigger this problem. 

Bottom line, can't use any external mic source at all anymore.
