Insight Connector for Courier-IMAP is a commercial plugin for Microsoft Outlook⢠that allows native Outlook groupware capabilities using Courier-IMAP. Outlook users can perform tasks typically available only when using the Exchange server, including folder sharing. Some of the features include folder sharing, public folders sharing, appointments/tasks scheduling, real-time data management, calendar sharing and other collaborative tasks.
A trial version of Connector can be downloaded from http://courier.bynari.net. This software is supported by Bynari.
so it is a commercial addon. ... than i think the answer is no.
Just because this particular implementation is commercial doesn't mean that an open source version couldn't be done. So, you are wrong - the answer is not 'no', it is 'yes, it *can* be done, but apparently there is no open source/free version at this time'.
I only posted this as a response to your question about using imap to store/retrieve contacts.
And if it matters, I was as surprised as anyone when I read that announcement.
