MS Teams Desktop Client not passing through Camera Video to other users
Home2020 I would imagine something in the devices network stack, for example the client firewall.
When you use the browser traffic is sent over https TCP port 80, the Teams desktop client will try to use UDP Port 3480 for Video.
StevenC365 Good Day, these are Domain managed computers so we would all have the same Windows firewall settings and the Network firewall is controlled by our domain Admins. So if UDP Port 3480 for Video needs to be open it would already be open as all other clients are working just fine. Does seem to be open though when I check. Looks like I'll just have to reimage her another laptop just because we can 🙂 This is a weird one though. Even tried setting the Internal Camera driver as a USB Cam Driver from another post i read but still didn't work. If anyone else is reading this, the Laptop I am working with is a Lenovo ThinkPad X1 if that matters.

@Steven Collier Starting in the last 3 days , we've received reports that teaching staff can see their video image from the camera but their student's cannot see them. This problem is specific to the Teams desktop app as the video works fine when using the browser version of Teams. We've asked them to check for updates but most are running the latest version of Teams. We are also running on Domain managed computers and all of them are the same make and model. The firewall ports are not the problem so any other suggestion you could provide us would be greatly appreciated.
