Cortana and outlook integration

[D0gsballs]

Hi all,

Sorry if this is in the wrong section.

I'm an old Windows phone user that has been on Android now for probably nearly 2 years now. I always like to try different things and at the moment checking out Cortana and the Outlook apps. One thing I can't figure out is where cortana gets the calendar information from. It seems to be from the calendar app on my phone rather than from Outlook, either the app or servers. Am I missing something or should it be getting the information from the app or severs?

Thanks.
