Can't see myself on the viewfinder during the call

I'm not sure why or how, but I think it might have something to do with the way various tech is integrated. I can have someone create a meeting (in my enterprise) and on the appointment it has a link that says "Join Microsft Teams Meeting" and it will open teams and join the meeting. It's almost like they setup the meeting while logged into an account other than the one used in our enterprise...or maybe they weren't authenticated at the time or something. In those cases, it's messed up, no self view, in fact there is no "Join" button in the Teams calendar view. I *must* use the link in the appointment to join. Which is weird because it is still on the calendar.

It seems that whenever I am able to join a meeting using the "Join" button on the calendar, everything works as normal, self view is present, everything is good.

Why some meetings on the calendar have a join button and others are missing it, and only have a link inside the appointment, I do not know. My guess is it has something to do with how the meeting scheduler scheduled it and/or what kind of an account they have.

George, I have the same problem. A few weeks ago I was able to see myself in the lower right part of the screen in Teams, but that is not an option. I deleted the settings.JSON in the Appdata>Roaming>Microsoft>Teams directory as others had suggested -- but no success. Others in my enterprise CAN see their screen.

I have this issue too.  I use to be able to see myself in a small box on the bottom, side of the screen when in team meetings. 

Since adding a photo of myself the box no longer appears.

I am going to have to remove the photo to see if I can get this box back as it was very helpful in 'checking' my camera position. 

A shame that i can't add my photo and have this box as well.

Can you please fix this, thanks.

I have this exact problem, I would like to see if Microsoft have an answer

I think this is a bug. I've always gotten a self view in teams meetings as well. However, now I'm not seeing it anymore. I have an older Lenovo W531. It shows the self view. I have  brand new Lenovo, it does not.

Additionally, the "Turn on camera" button does not work on the new Lenovo, but it seems to work find on the old one. I think the latest version of Teams has problems.
