[Q] no "Exchange" option in my stock email app (4.4.2) unlocked GSM version
I need to use exchange to sync with my company's calendar.
I have noticed that other Nexus 5 has an "Exchange" option when one goes to Setting --> Accounts --> Add an Account --> Corporate
illustrated by this link:
(page 4 out of 8)
But my Nexus 5, which is also a stock ROM with no modification, doesn't even have this "Exchange option"
I desperately need that exchange option. How to get it? Is there an stock email app that I can download / flash?
My phone is rooted with no custom recovery installed. Can I get away without a custom recovery?
Thanks in advance
