[General] Outook App not connecting whilst on 3g

Hi All,

Been pushed over to the new outlook app from hotmail yesterday. I the issue im having is that it wont connect and download/recieve/notify me of any emails if im on mobile internet. If i connect to my Wi-fi at home, within seconds they all come flooding in.
It does nothing if i try and refresh it either.

I have 3 "hotmail" accounts on the app, all of which worked fine when still using hotmail app.

Any help would be appreciated.

Android version4.1.2

Thank you.
