Times not appearing as scheduled, appearing as next half hour
 

We have a user who looks after one of our meeting rooms. When someone books
the meeting room a notification is sent to her. She will then go into the
meeting room inbox and accept the calendar item. It will respond to the user
who originated the request at the correct time but will put it in the meeting
room calendar at the next half hour from the current time. So if the meeting
was set for 11am, the current time was 8:15, the originator of the email
would get a response of 11am. The meeting room would be booked at the next
half hour or 8:30.

Does anyone know the cause of this?

We are running exchange 2003 SP2 and 2007 outlook clients. All are on the
same timezone.

thanks,

Paul
