What we need is as follows:
An Application which runs local on a PC and talks to ActiveSync from Microsoft. It synchronised all the items from Microsoft Outlook (like Calendar,tasks,e-mail and contacts) and sends the results to an Webservice (we build the webservice). And the other way around. Basically the programn imitates a mobile device, gets the information and needs to share this (XML based) with our online programn.
The tool needs to work with Outlook 2007 and 2003 in different language settings.
