MS Teams Video quality is terrible
[SOLVED]
I called with microsoft. The problems could be solved when you deleting the cache of Teams!
o Close Teams (dont forget the background process)
o Go to %appdata%\microsoft\teams
o Delete all files and folders here
o Start Teams again
The preview stays very bad quality, but when a call is made, the other end has "better" video. But it will be max 720P in teams.
I'm having the same issue. I initially thought this was limited to my new Logitech Brio 4k camera but i've also just now noticed that my older 720p camera also is being transmitted it lower than 720p resolution when using the Teams desktop app. The drop in quality is more extreme with the Brio 4k camera which Teams won't even transmit at 1080p on the desktop client. I'm not sure how Microsoft and Logitech can market the devide as certified for MS Teams - although it does appear to be an issue with the Microsoft Teams app rather than the Logitech device which works better on the Teams web app.
Farook_Naji, et al,
I have seen a marked improvement in Teams video quality, not sure what exactly changed but my org is now seeing 1080P when all variables are of adequate quality, especially available bandwidth and low latency of local and Internet connectivity. I have tested one-to-one with other staff and a meeting including a Microsoft Teams room, all participants had high quality video. The quality of video was very detailed, so much so you could see single hair strands now (provided camera was seeing a head shot, like sitting in front of a desk monitor).
Be sure to check Meeting policies and allow a bit rate where you'd like to aim or control bit rate too. I have set our tenant general policy to "16000" (16Mb).
Here's a couple of good links to review:

Hope you see an improvement too. Our Teams meetings appear regularly to be better than Zoom now.
I haven't seen any improvements, and remain on the latest client version. However, i have done some more testing and I think i may have come across the cause of the issue in my case.
I have conducted a Teams call in the desktop client by joining a meeting using my guest account on another Microsoft 365 Tenant. The video transmitted from the same device (and on the same network connection) on this call was much better. Looking at the call health, the resolution was hitting 1920 x 1080 and the sent video bitrate was much higher.
This leads me to believe that the issue in my case is with my organisation's meeting policy settings in the Teams Admin Center. Specifically the media bitrate setting is probably set much lower than is necessary. https://learn.microsoft.com/en-us/microsoftteams/meeting-policies-audio-and-video#media-bit-rate-kbps
Unfortunately i don't have the privileges to check this setting in the Teams Admin Center for my organisation.
The docs don't state that this setting should cause different behaviours between the web and desktop client so this may not be the real cause but there's definitely a difference in behaviour on the desktop client between meetings joined from different Tenants.
