bradstewart: I'm using the default KitKat email client (not Gmail) with an Outlook.com account as well as an exchange one and multiple messages are not being threaded.

I use it aswell, Have my own domain with outlook.com

Good gui and no issues. But we cant expect Outlook 2013 from a phone..

Lack of threading is a plus for me. For work purposes it makes life considerably easier.

K9 Mail does threading.
