ZideOne is working on solutions which integrate contact, event and todo list servers with Microsoft Outlook™.
The core is a MAPI Message Store Provider which maintains a write-through offline cache on a remote HTTP server.
Our core connectors synchronize Outlook data using the WebDAV, GroupDAV, CalDAV and CardDAV protocols. They utilize the vCard and iCalendar data formats to represent the data.
The connectors are not released yet. If you have questions on licensing, please send mail to sales@zideone.com.
Thanks for your patience.
