Relax browser support check
The current browser support check is too pessimistic and prevents some modern browsers from loading Microsoft Teams. For example, up-to-date Chrome on Ubuntu Linux is not considered a supported browser, even though changing the User-Agent string to Chrome on Windows allows Teams to load without any problems.
Please consider a) just letting the browser try to load Teams, b) using feature detection instead of the User-Agent string, or c) blacklisting known broken browsers instead of whitelisting if the User-Agent string is used.

This is still under review by the feature team. No new details yet.

Now Linux browers can access Teams, but audio and video is not possible.

Teams works fine in Chromium on Linux. Quit making me spoof my user agent please. Sigh. Rookie stuff here.

Teams says my browser is unsupported but it’s Firefox 52, which is supposed to be supported. (OS : Debian)
Same issue with Chromium (Google Chrome Opensource version).
I have no problem with the other Office365 apps.

Any updates on how this is progressing?

For Firefox ESR, you can use plugin ( https://addons.mozilla.org/en-US/firefox/addon/uaswitcher/ ) to fake user-agent to Edge, Chrome or newest Firefox and Teams works just fine. So this is completely artificial limitation that has to go.
MS: You don't have to actively support every browser out there, just don't limit access. A note of officially supported browsers in appropriate place should be enough. -

Yeah, we aren't gonna even touch it until I know it can work. I just don't understand how O365 can run fine almost on any browser but so many restriction to use Teams. Very annoyed. My team will not be using this until they take of that crazy browser restriction check.
I cant get it to work on newest Firefox, Chrome, or Chromian on my Linux machine, and cant even get this to work on Windows 10 running Firefox, and since updating on Chrome. Sorry Microsoft I don't want to use your browser, but I have users on Apple too, can't get in with Safari, granted Safari is terrible, but even on Firefox for Mac is not working, same error message. Please fix this, otherwise we will just avoid it.

Opera is based on the same rendering and JavaScript engine as Chrome. So not supporting Opera and other Chrome-based browsers is just another non-technical and political decision to marginalize competition and innovation.

I'm in a situation where my corporate laptop doesn't allow me to install the desktop app and the version of Chrome our company locks us onto is either too old or has too many hooks into it from AV and Teams says it's not supported. There needs to be a concerted effort to stop using browser detection and use feature detection.

doesn't work in numerous browser. policies in the company do not allow quick update of Chrome and Teams do not work on IE11 nor 3-month's old Chrome! it's ridiculous.

Worse yet, Vivaldi is the best browser out there from an Accessibility perspective, as a sight impaired user that's why I choose to use it, and yet Microsoft are choosing to discriminate by blocking Teams within Vivaldi - even though it actually works just fine (the rendering and javascript engines are those from Chrome / Chromium, it's just the UI that differs, and the UI of the browser has zero effect on whether a web page loads, renders or operates as expected). Very poor show Microsoft!

Teams Desktop eats RAM like a starving man. Relax Teams' browser support.

My team have reported that when using Teams in a Linux web browser, that it is problematic, the best issue is that when the web browser is not open, it takes between 2 and 4 hours for the email notification to come through, please fix asap or get the Linux client out
