Link2Exchange is a hosted exchange and BES provider that also sponsors the blackberry forums. We have had a number of requests from our users that would like to share calendars, contact lists and tasks between users or between public folders and users on their Blackberrys. In response to this we have implemented a new service called Sync4Exchange. This service is available to mailboxes in our hosted exchange environment and this is the only hosted service of it's kind. Please go here to view more information on this service.

We are also still running a promo for blackberryforums members.
