Week Calendar App - my primary calendar is Outlook on a network at work - request your tips

Does anyone have a tip for me - I just downloaded the "Week Calendar" app ($1.99) on my iPhone 4S.

I take it that it picks up info from the regular iCal on the phone.

How can I sync these calendars with an Outlook calendar that's on a network at my job (like I'm able to do in order to read my work email, having set up an account with Microsoft Exchange webmail)?

Please speak s-l-o-w-l-y and give details.

Thanks for any help!

Kindest regards.
