On Instagram, we posted a video showing a general demonstration of Microsoft Teams and some idea of what's "on the roadmap" and coming soon to Microsoft Teams.
As you can tell, there are still some things Microsoft Teams can't do right now, but from what you can hear, Microsoft is aware of the issues and/or plans to fix the issues. While the Office event might not be going as well as the Microsoft Event last week, Microsoft Teams was an expected announcement and may not be meeting everyone's expectations right now.
If you are interested in joining in on the conversation, you can follow the conversation via the MS Tech Community. There you can give answers to the Microsoft Teams engineering team on any comments or suggestions you may have via the Microsoft Teams UserVoice.
Download the Microsoft Teams apps on Android and Windows 10 Mobile. Microsoft did offer an iOS version, but it is mysteriously absent from iTunes. We will keep you posted on the Microsoft Teams Roadmap as soon as it becomes available. For now, you can check out the Microsoft Teams FAQ.
