I have a user that is attempting to schedule an appointment for sometime in July of 2008. she is able to create the new appointment and invite the attendies, but when she looks at the scheduling to see if there are any conflicts it shows that no data is available(white box with slashes). All users being invited are members of our domain, with their mailboxes on our exchange server. I have tested this and it does the same to me. If i open a users calendar i can see that there are events on there for the time period in which the meeting is being scheduled. Thank you in advance for any help you may provide.
