2011 Exchange account (Mac) won’t sync with Exchange OWA

Okay, bear with me: I'm an end-user and not especially technically inclined.

I'm trying to make an Exchange account so I can sync my Outlook calendar, etc., to the online Outlook provided by my ISP (Sympatico/Bell Canada).

"Configure automatically" doesn't work and I've tried a number of naming conventions for the server, from "live.com" to pasting the actual URL of my online email page, to the URL of the online Outlook OWA calendar, to the one that works with my Nokia handheld, all to no avail.

I've spent an hour and a half with Bell's online support and their techie couldn't resolve the issue; their bottom line:

"It seems there is some issue with the settins.I suugest you to contact microsoft to resolve the issue."

The frustrating part is my Nokia N8 mobile's Exchange mailbox settings works perfectly with my online Outlook, including syncing its calendar with OWA's calendar. (See image for settings)

But these settings won't work from Outlook 2011 on my Mac.

Suggestions?
