[CalendarServer-users] ical invite mail not being sent

[Peter S. Easton Jr.]

Hi All,
I'm new to this board and OS X server 10.6, so please forgive me if this is the wrong place to ask this...
When I make an event and invite people within my AD no invite is sent but if i enter an email address of a person not in my AD they get an invite.
am i missing some settings or something?

Thanks in advance.
