I tested it also, it is not working I get : Login error: Guest user OID is missing. User is not redeemed. (code 0) I do not use Spectrum2

If you want to add support for MS Teams Personal (free), have a look at the unofficial API which I am using in my Krak Bot chat bot, as well as the user enumeration in MS Teams Personal and MessagingAPIService.json.

There's a first cut of a Teams personal/free in the above commit if anyone's interested in trying it. (or https://github.com/EionRobb/purple-teams/actions/runs/7948474584/artifacts/1254441417 for Windows people)

It shows up as a separate protocol in the dropdown list as there's some subtle differences between the two, including a different authentication client id.

I've only tested out the bare basics of sending a few one-to-one IMs to myself, so would appreciate some feedback of things that need improving :)

@EionRobb I can confirm Teams Personal works in Pidgin 2.14 on Windows 10! However, it doesn't download any user names (only IDs) until I restart Pidgin:

There are also some empty contacts in my buddy list without any ID:

Also the list of rooms is cryptic, showing only IDs, as well as some hidden/deleted meetings:

But apart from that, the greatest thing is that this Teams client takes only 15 MB of RAM instead of hundreds MB! 🎉

Well done, thank you!

One question: does deleting a contact from the buddy list remove it also from MS Teams server? I don't think it would be desired outcome.

A major issue: I cannot send a message from Pidgin directly to a buddy in Teams (live:.cid.xxxxxxxxxx), I have to open a chat room with me & him (19:uni01_xxxxxxxxxxxxxxxxxxxx@thread.v2) and type my message there. This is counter intuitive.

Ah! I hadn't tried sending any new outgoing messages, only replying to incoming.

Those 2 issues you describe might be interrelated though, there's different ways of detecting a one-to-one chat to what's in the Teams for Work, and it doesn't sound like it's linking the chat room up with the contact properly. Fingers crossed solving one solves the other!

I believe sending messages on Teams Personal accounts works ok now, as of a few commits ago? Please feel free to reopen this issue if it's still a problem
