I'm currently setting up my work system and totally lost at getting Microsoft Teams running. Other Microsoft Office products (like Excel, Office, Word) are working seamlessly for both native and web version, and for now only Teams seems to not work (also for both native and web).

Whenever I try to sign into Teams there's a redirection loop:

```
↱ https://teams.microsoft.com/go#
↳ https://teams.microsoft.com/go#id_token=xxx&session_state=xxx

```

... until being redirected back to the login page after about 10 seconds with the vacuous message:

```
We couldn't sign you in. Please try again.

```

It's working on a colleague's system, so it's not an account or licence issue.

I googled it, tried Chromium, Firefox, Opera, several packages like the widely-used `teams-for-linux` and even the official client for Insiders, `ms-teams`, tried both AUR and Snapcraft packages, and even built them myself - nothing worked. It's always the same behavior as described above.

I'm using the i3 community edition of Manjaro (freshly installed).

I'd be very thankful for any kind of ideas.
