We are currently running our mail through Microsofts Hosted Exchange Service, Liv@EDU. It's working great for all PC users and Windows Mobile users. The problem is some of the users are Blackberry Guys. Is there a workaround or a 3rd party product to wireslessly sync our Blackberries to Outlook Live. We thought about getting a couple of accounts with Blackberry support hosted by another provider, then we have and the users just IMAP thier email. But then we run into problems with Shared Calenders etc.. across 2 Exchange Servers.
