Teams is my favourite application within Office 365. Like the IT Pros in our panel today, it is a subject I'm very passionate about. As a hub for team collaboration it integrates people, content and tools to make the Team more engaged and effective. It has been a runaway success. Since it's introduction it has been the fastest growing app in Microsoft history. Back at Ignite 2018 we saw the numbers - 329,000 organisations using it (over 400,000 at the time of writing), 87 Fortune 500 companies and 54 companies with more than 10,000 active users (Microsoft, 2018). Yet it is also a young application and as such it is still evolving rapidly. Whilst positioned as an Inner Loop collaboration app, by introducing features such as the 5000 user limit or (soon to be) Private Channels, we ask - is it evolving into something different from it's original design and purpose?
