Introducing Microsoft Teams Rooms (Updated)

Petri-X , all features should have a Message center post that goes out 30 days in advance of hitting the GA. Please search for Team Rooms on Windows from Message Center in your Microsoft365/ Office365 admin center to keep track of what's coming. All features are also posted to Microsoft 365 roadmap site with title "Microsoft Teams: <Feature name> for Teams rooms on Windows". This should provide ample heads up for you to know what's coming. 

Starting in Q1 2022, we will enable Public Preview for both Web client and Store builds ahead of GA release. You can opt-in to Web client features "Public Preview" today as well using instructions posted at Public preview in Microsoft Teams - Microsoft Teams | Microsoft Docs but it will require an additional step to log in to room account from Web browser and enrolling in "Public Developer Preview" similar to Teams desktop client. In Q1 2022, we will make it easier to enroll devices into public preview using XML and Teams Admin Center and utilize Tech Community Microsoft Teams Public Preview - Microsoft Tech Community forum to make announcements for all upcoming features. Please stay tuned for more documentation/ tech community blog on how to enroll in public preview early next year.
