    • %LocalAppData%\Microsoft\OneAuth

    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)

    A more professional solution (yet it needs to install outdated version): https://answers.microsoft.com/en-us/msteams/forum/all/problem-with-teams-when-changing-tenants-message/bd7f73d6-4d90-45cf-ae9d-f64a75960ee1
