10159 Mail and Calendar not opening...just shuts down

That's too bad, I'm sure there is as Microsoft is nearing release. The worse is you'll have to wait till the 29th which is not that far away.

I have the same thing, even after I updated my PC today 8/12/2015, mail/calendar/onenote/app store are still not working!

Your issue is probably different since this thread refers to an old insider build. There is an issue right now with the released version of Windows 10. Microsoft has said they are working on a patch that should be out soon.
