Hi, I'm not really sure if this is the right place to discuss this, so if you think I should go somewhere else, let me know. Zope can be used for a lot of different purposes, but one of them definitely is groupware and there a lot of people I have been trying to convince to use Zope prefer Exchange for the simple reason of integration with Outlook. Now, Outlook is not as closed as you might expect and I have been thinking about ways to integrate Outlook with Zope. If you could make Outlook cooperate with Zope in a way that Outlook would create and use public folders that are stored on Zope, lots of really interesting applications would be possible, ie like sharing agenda's and having a zope interface to it too for html rendering and allowing emails to be moved from outlook directly to Zope. I see three strategies to achieve this: 1) Add a MAPI server interface to Zope. With a plug in for Outlook like the one from Bynari Outlook users could then manipulate Zope objects. The MAPI interface would have to render Zope objects as MAPI folders and messages. 2) Reverse engineer Exchange and implement the relevant MAPI interfaces in Zope. This would be the most transparent way, but it would also be very complicated and would depend a lot on the whims of Microsoft as far as interface changes go, never a very confortable position. 3) Write a plug in a la Bynari's InsightConnector, but then one that doesn't communicate with MAPI, but directly with Zope, using one of the standard by Zope supported protocols. So, I would prefer the third one, but I don't have much of clue how to do this. Does anybody have any pointers where to start, ie documents or example implementations. Are there any projects like this already going on? Any help is appreciated. Douwe Osinga
