Is Exchange part of Microsoft?

Excuse me, I came across this question recently and I'm a bit confused. I understand that Microsoft is a tech giant, renowned for its software and services. But, is the cryptocurrency exchange platform, commonly referred to as "Exchange," actually a part of Microsoft? I'm genuinely curious about this as I haven't found any clear information on the internet. Could you please clarify if there's any connection between the two? It would be greatly appreciated.
