KDE Kontact already supports Kolab-XML and Horde will support the format in Kolab 2.2 (coming soon TM - points finger at Gunnar). So you will have a choice of 3 commercial Outlook plug-ins, one very reasonably priced, and native Linux and a web clients. We also have a migration tool from MS Exchange to Kolab, mail and groupware objects like calendars, contacts, tasks, etc., still in beta. < SELF PROMOTION OFF > Kolab might just be worth another look. http://www.kolab.org/ Best Regards Joon Radley Radley Network Technologies CC Cell: +27 (0)83 368 8557 Fax: +27 (0)12 998 4346 E-mail: joon@xxxxxxxxxxxxx Web: www.toltec.co.za ---- Cyrus Home Page: http://cyrusimap.web.cmu.edu/ Cyrus Wiki/FAQ: http://cyrusimap.web.cmu.edu/twiki List Archives/Info: http://asg.web.cmu.edu/cyrus/mailing-list.html
