Exchange 2003, Outlook 2003. All users have Free\busy settings to 12 months (via a script that changed the registry). All users showing the 12 months in Outlook. problem is that some users only show 3 months of calendar entries, and the future months do not display (hash marks).
When we run the "outlook.exe /cleanfreebusy" at the desktop, the calendar then becomes viewable. BUT, the next day it is unavailable again. Could a GPO be doing this? Any other ideas?
