Outlook Resource showing "No Information"

Hello,
I have Exchange 2003 and Outlook 2003. The meeting rescources (on 2
different mail servers) are coming up with no informaiton (the white
box with a black angled line through it) from April 1st onwards. Is
there some sort of setting that only allows schedules to be viewed a
few months ahead??
This is the the meeting request view.
If i go into the calandar view of the meeting rescource i can see the
events around April 1st. There are meetings, just in the other view i
cant see them in the meeting request view.


If i login as the resource user and run the outlook with the outlook
/sniff and /cleanfreebusy switch, dismiss the 400 odd reminders, then
go back and book the
schedule on my box everything is ok.
Any ideas why it is doing this?
I would have just left it as the above as the resolution but i have
heaps of rescources and i dont want to have to do it to them all.
Thanks
A
