Outlook Resource Calendar Double booking

[btfbaka]

I am currently using Exchange 2000 and have Meeting Rooms configured as
resources. What I have notice is that if you try to double book a room with
the same time and date the system will notify you that it can not be done
provided that it is within 11 months. The glitch that I have found is that
if the double booking is 11 months or further into the future it will allow
the double booking.

Does anyone know of a fix to correct this problem...a patch or configuration
parameter change?

Any suggestions will be appreciated...Thanks...btfbaka
