Outlook 2003 no calendar information on other when trying to create a new meeting invitation

[QH]

We have an Exchange 2003 server running in a regional office on a
Window 2003 server. All that office's users run Outlook 2003 on a
Windows 2003 / Citrix platform. The server replaced a Windows /
Exchange 2000 server, from which all the mailboxes were migrated about
6 months ago.

People in the regional office have found that when they try and book
meetings, for some people their calendars can be seen without a
problem, while for others it is just crossed out with no information
given. Everyone has a default setting of 2 months for free / busy
information. Interestingly, they claim that for one person, they could
not see the calendar information yesterday, but can today.

I looked this up on various forums, and some people recommended
deleting the anonymous permissions for the calendar, and then allowing
this to be recreated. However, after I deleted the anonymous
permission, it did not return automatically and I could not add it
either (obviously 'anonymous' is not listed on the GAL for me to add).

Any ideas people?
