We've recently installed Exchange 2007 and moved all our mailboxes over from 2003 except for a few.
The exceptions are the users who have Blackberries. We do not run the blackberry server, we maintain ours thru their website since we only have a few.
Inside the web site we currently have the http://mail.abc.com/exchange and tried changing it to the new exchange box by http://mail.abc.com/owa but receive and error the mailbox can not be reached.
How do you configure either the blackberries or the exchange box without purchasing the server software?
