I used to work within the Office group. The way that data is organized in Exchange is mind-boggling -- and not in a good way, IMO. Its design is from decades ago, and trying to understand how to find something really takes a lot of experience. Without going into any gruesome details of how it works, I'll just say that it is a HUGE hurdle to being productive for day-to-day work.
Similarly, I'm not surprised that there's some kooky way that the Teams folks shoehorned their data into the existing Exchange system -- they probably have no other way to operate at that scale without taking years in writing their own database system. (I can't imagine that using SQL Server to do this would be viable, either, given what they want to do and the capabilities already built on top of Exchange.)
