Using Teams with multiple organizations
ChristianJBergstrom Unfortunately, based on the descriptions, https://www.microsoft.com/en-ww/microsoft-365/roadmap?filters=Microsoft%20Teams&searchterms=70766 is an expansion of the existing Teams federated communication model, and as such, still will not provide any of the functionality requested by the majority of users, due to requirements to maintain information within specific tenancies.
Additionally, https://www.microsoft.com/en-au/microsoft-365/roadmap?searchterms=68845&rtc=1&filters=Microsoft%20Teams&searchterms=68845, which was originally expected to bring multi-organisation logins, did not deliver the necessary functionality to provide what has been requested here and https://microsoftteams.uservoice.com/forums/555103-public/suggestions/17750851-i-want-to-use-multiple-teams-accounts-at-the-same.
Are you able to point to an actual roadmap item that will bring the same functionality that already exists on mobile apps to the desktop clients? (To be clear, that is, any combination and number of concurrent logins — not just one organisation and one personal account.)
