I have a user who reported she no longer can see free/busy information for
some users more than 2 months worth from scheduling screen (running Office
Outlook 2003 SP3). When I browse the same user myself also on Outlook 2003,
I can see up to about 2 months and the rest shows \\\\\\\\

What would have caused the free/busy information to show more information on
one user's screen and not others?

Server is running Exchange 2007 SP1, clients are Outlook 2003.

Thanks for your help.
