As always with Nylas, I've got very little understanding of what's going on here. The API business must be successful, but I wonder who is using it, other than people making e-mail clients, and they all seem to have their own!
N1 was the first good desktop alternative to Outlook for Exchange in a loooong time, so I was hopeful this would be a flier. Is it going to be possible at all to use the new open source app (or any forks) with Exchange?
