I have mine working on OWA. I use BIS with Rogers and it allows for OWA.
For yours, you would navigate to BlackBerry Internet Service
Log into that or create a new account if you haven't already.
Under Email Accounts, click Set Up Account.
Put in any email and any password (make them the same though). Basically, we want it to fail. And click Next. It will do it's "processing" for a minute and then ask for Additional Information.
Select "I will provide the settings to add this email account." and click Next.
Select "This is my work email account." and click Next.
Select "I can access my email account using a Web browser (Outlook® Web Access)" and click Next.
As for the settings, that's up to you. Now I will note that it took me some tinkering to get mine to successfully log in. Here's why. I have my own domain controller/exchange server at home. My log in name is "Firstname Lastname" with the space in there. I ended up having to use "Firstname
" for the username.
But once you get the right settings, you should be good to go. I had read that this setup was the type that would only send emails every 15 minutes. But mine hit my blackberry a second before they even hit my Outlook, which is connected right to my network. So it's pretty fast =)
Hope this helps!!!!!
