Hi @USB

Thank you for raising this issue. Many users have been troubled by this issue recently. I have reported this issue in the Microsoft 365 Admin Center. If there is any update, I will reply to you here.

In the meantime, please use the Teams web client, which is not affected by this issue. Thanks for your understanding and support.

Same here, testet different MS Accounts on different Guest-Teams --> maybe Bug at the actual Teams App itself ?

At least one who tells us, that Microsoft is working on it, instead of reposting a ChatGPT answer (word by word) "Quit teams, delete the cache, if it's still not working uninstall an reinstall teams ..."

A bit of a convolute procedure, but have a look at Alessandro Caputo post in this thread (towards the end): https://answers.microsoft.com/en-us/msteams/forum/all/error-loginhint/85d47ad0-5f43-4ebe-8756-c78226203be5 worked quite well for me (not perfect but it's the best workaround I've found so far)

Sorry, but this doesn't change anything. There's no "use new Teams" option or something like that. It installs the same desktop version of teams like before, and the error occurs again.

The Option mentioned above ist not really a new teams, its the new "use website as app" story:/

If you have any doubts, I encourage you to ask for detail to the original poster. For me it worked at second attempt.

Oh, yes, I have my doubts. Teams Classic no longer exists and is no longer available for download from Microsoft.

The current version doesn't offer the options mentioned, so it doesn't work.

@Diego Cecchin Ok, this solution works on a private PC, but not on the computer of a company that follows a zero trust policy. We need a solution that works without downloading outdated software from dubious sources.

Ok Michael listen, I wasn't even going to answer your comment for the sake of quiet living, but since you kept complaining and addressed myself directly I'm going to write a few lines: don't you believe that I myself would like a multi-billion company such as Microsoft to release work-out-of-the box software? Don't you think that I understand that this is a rather sketchy procedure? Don't you think that someone else might find it useful nontheless to overcome the temporary problem?
If you think that this is not a good solution downvote it, highlight the parts that don't work for you, research the internet for alternatives, contribute to the community, rather than just complaining to me. You got wrong both the arguments and the form.

@Diego Cecchin It's really disappointing that Microsoft doesn't seem to offer any real support anymore and instead shifts the responsibility to the users by referring them to some community platforms. This results in thousands of users having the same problem, but very few finding actual solutions.

A solution that requires downloading outdated software is unacceptable - especially when it is not even clearly stated where this version can be safely downloaded. Such recommendations pose a significant security risk and are therefore by no means a suitable solution for all users. I have to make that very clear.

Of course, everyone is free to respond to my comments or not, but I would like to make it clear that this is not a satisfactory answer for me.
