Sorry for the delay on an update on this one! I’m hunting down the status for you and will update once I have it.
Also, if you are interested in participating in testing or surveys for this, just tweet me at @skprufo.

We're starting to explore and test Teams. We are looking for ways to have team calendar for specific topic. Our idea was to create meetings associated to a channel, which is feasible. However, we didn't find a way to see effectively those entries within a calendar view. We can only see the meetings appearing in the conversation, which is not enough organised. It seems obvious but I realise by reading this forum thread that I'm not the only one searching for a such solution.
