Microsoft Teams: Unsupported Browser

TbGbe · Win: Snapshot Vivaldi 7.4.3671.3

@s_paternotte said in Microsoft Teams: Unsupported Browser:

Are there any downsides to having the user agent switched to Edge all the time?

Well, you're NOT using Edge!
User agent switchers are a "crude" workaround for badly written websites and their need should result in a fault report to the website maintainers.

Let's chime in at Microsoft Teams Uservoice

Until yesterday, the User-agent spoofing fix worked OK. But now I cannot get it to work any longer, no matter how much cache I delete, and using either Developer tools or a Chrome extension to spoof the user agent. Can MS have changed anything on their side? Or is it the latest Vivaldi update causing this?

dsteadson

@thomassvensen I think it's a result of changes to Microsoft's authentication process. I managed to get it working by adding microsoftonline.com and sharepoint.com to the Edge spoof list.

Unfortunately can't get it working in the Web Panel, which is what I'd like! I'm guessing the spoofing extension doesn't apply there. Anyone know how to get that working?

@dsteadson

Hmm, I tried teams.microsoft.com, microsoftonline.com, and microsoftonline.com set to spoof to FF33, but that didn't work. I picked the most popular extension under "User-Agent Switcher", but it doesn't appear to have an Edge option.

Any ideas?

I am not running Windows at moment but I would start Edge open https://www.whatismybrowser.com/detect/what-is-my-user-agent
and add it to UA switcher in Vivaldi.

Cheers, mib

Use this plugin
https://chrome.google.com/webstore/detail/user-agent-switcher-and-m/bhchdcejhohfmigjafbampogmaanbfkg

set it to chrome 75.
Job done

The user-agent switcher with the edge agent string doesn't work for me. It is impossible to login to Teams using Vivaldi.

I did add my vote and request in the microsoft's site.

I don't get it, though; if Vivaldi uses a chrome user agent by default, why doesn't the site accept that?

S_Paternotte

@Khaolos I had this problem as well and I have found this User-Agent Switcher and Manager to take care of it.
Website: https://add0n.com/useragent-switcher.html

The user-agent that works for me: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/77.0.3835.0 Safari/537.36

As https://teams.microsoft.com/ really is my only problematic website I have used the following options in User-Agent Switcher:

White-list mode: teams.microsoft.com
Do not spoof: google.com/recaptcha
(Hmmm, does this really apply in combination with the white-list mode? Probably not.)

It is absolutely outrageous that after so many years, Vivaldi is still blocked by MS

S_Paternotte

@Catweazle Let's rephrase: ... that after so many years, Microsoft still does not accept Vivaldi

It is logical that they want Windows users using EDGE, but then it would also be logical that they also block the other browsers (FF, Chrome; Opera, etc.), which is not the case.
Browserwar against an awkward competitor.

S_Paternotte

@Catweazle that is exactly why I think it's just Microsoft being lax

Any road, I don't mind that much, because I've got this nice little solution running together with all my Vivaldi setups.

Of course you can skip the restrictions, changing the UA, but this is not a solution that I like too much, since Vivaldi presence on the network remains, which in my opinion is absolutely counterproductive.
If you disguise Vivaldi, these pages are never in need of removing these restrictions.
The browser sniffing should have only the purpose for statistics, never for discrimination, this is the same as if they put on the streets of a city a sign 'Only allowed for Mercedes, BMW and Volkswagen'. It is exactly the same, a disdain for the user.

To anyone having difficulty with the user agent switcher not working - here's what is actually happening:

You visit the page without the UA switcher turned on
You are redirected to the "unsupported browser" page
This sets a cookie which "remembers" that your browser is unsupported

You need to clear teams cookies, turn on the UA switcher, THEN visit the main teams page.

If at any point you end up at the "unsupported" page you need to clear your cookies.

This results in the rather humorous outcome that if you visit https://teams.microsoft.com/_#/unsupportedBrowser in Microsoft Edge, teams starts telling you that edge is unsupported, and there's no way to fix it:

It also means you can trick people into clicking that link, and they'll lose the ability to use teams in their browser.

Teams working great in the main browser window since the 2.1 update, but still reports as unsupported in the web panel

Pesala

@dsteadson Right-click on the Web Panel icon, and select "Use Desktop Version."

dsteadson

@Pesala Thanks. That sort of worked except for Teams isn't even working in the main window anymore. Locks up the whole browser. Vivaldi Task Manager shows "Utility: Network Service" running at 100%, can't even dismiss the popup re notifications. Killing that service restores access to the site (then I can dismiss the popup) and it works OK in the main window, but in the web panel it doesn't resize correctly.

Just tried switching it to mobile and back to desktop to see if it would resize the content, and now it's back to "unsupported browser" in both windows. Damn cookies ... sigh...
