[Cars are the new horse]

I use "Nine" as my Exchange email app for work because it allows application level security rather than device level (i.e., I don't have to enter my PIN to turn my phone on, rather I just enter it when I open the email app). However, since Nine is not the stock app, it does not work with the car's email system.

Is there a way to have the system sync with non-stock exchange email applications?

(I actually have an M5 and posted this at the M5 forum, but then I realized it would get more hits here. I'm sorry for the double posting)
