Login problems via desktop app and web browser
thx for your answer. I’m trying to access with my domain account. On my mobile app everything works with my domain account. Only the desktop app says I’m not registered.
Sorry for the delay in responding. I keep thinking on this and the bit that throws me is that you say the account that is in question, is working as expected via the mobile app.
I am thinking that by default the teams desktop app will usually try and authenticate you via your same login as you logged onto your PC. And I can only think that perhaps you possibly have a personal account that has an alias of your work account.
So if this is the case I would go to say outlook.com and ensure that there is no associated with your work account, as if that account was used for Free Teams setup you could encounter this issue.
It might also be worth trying the web version via Teams.Microsoft.com
