Hi there, I'm running CalendarServer in the latest Version on my iMac for testing. Most is fine. May goal was to have in my calendar in ical the appointments both on my iMac and MacBook. Well and some other Calendars for resources. If I make new Appointment in the normal calendar (not stored on CalDAV) I can invite attendees without problem. If I start to type I get people out of the adressbook and mail sends perfect. But the first problem is when I schedule an appointment with 3 people from my company I have to type the email address like it is in teh accounts.xml that CalendarServer will notice them. If I just type the name or ID nothing will happen. The next problem is that I can't sent to an attendee from outside. Even if I drag an drop the vcard to my server based calendar. In the terminal I get a message that there was an error during post. I don't want to have to keep for one appointment 2 records one in the normal iCal calendar and one in the server based one. What do I wrong - or is it just not possible what I want? The next problem is that I want to delegate a calendar for reading to another person. It looks like it dosn't work with iCal. Is there an other way? Thank you for you help in advance! Kind Regards Gerhard
