I don't think it's a question to Microsoft.
You may see the specs. The mouse is meant to be compatible with Mac OS X 10.10. It was compatible with El Capitan (10.11), but it won't stay connected with Sierra (10.12) if you re-paired or initially connected the mouse with that OS. If you pair your mouse in El Capitan and then upgrade to Sierra then your mouse will restore connection and will function as it should (unless you re-pair it in Sierra). So the question should be addressed not to Microsoft but to Apple, I think. Something has got broken in Sierra. Correct me if I'm wrong.
