I have set up a public calendar called Conference room 1 for booking purposes in Exchange 5.5 SP4 and have configured appropriate permissions. My problem is when my secretary goes into her calendar and create a new appointment/book the room and then invite the "conference room 1" as the resource we are unable to view that calendars schedule (I made sure that I unchecked "hide from global address book so that we may select it in outlook), It shows that the calendar information is unavailable according to the legend at the bottom of the "invite" page. I am however able to see everyone elses schedule when I invite them to attend just not the resource "Conference Room 1" which is a public forder (calendar) for that matter. Is this the limitation of using public folder/Calendar or is there some setting I am just missing? Any help would be greatly appreciated. I
