So i have had a look @ the entire darwin isntall of calendarserver and really like it, did not take long to configure and start using with my mac's and ical HOWEVER trying to get anything working with outlook has not been quite so simple, the site says to use openconnector.org's product which i downloaded from http://sourceforge.net/projects/otlkcon/ configuration i had a look at their video on the configuration and i guess i dont really *get it* i get these elements... username password but there are two options home address principle address can some treat me like a two year old for a few moments and explain these differences for me so i know how to configure the mapi for use with the same server... in ical i set http://192.168.1.250:8008/ as the server address and ical automagically worked out that it should be http://192.168.1.250:8008/principals/users/test/ so i thought maybe that is the *home* and *principlas* address's for the connector... but it hasnt worked out that way.... anyone had any luck and able to point me in the right direction please i click on the save then browse... to choose the calendars... but nothing..... ideas? :-) many thanks ash
