Outlook 2003 Calendars Automatically Reorganize in Navigation Pane
 

We have recently installed Office 2003 for two of our executive assistants
who have the responsibility of managing many calendars. They probably have
access to 20-30 calendars that they can view for various reasons. Since
installing 2003, they have informed that they are having issues with the
calendars reorganizing within the list in the navigation pane. For example,
they have a calendar named Laptop A and they have placed in at the top of the
list, but for some reason all of a sudden it will be at the bottom of the
list. It happens with different calendars and we have been unable to tell
what prompts the reorganization. They would like a resolution to this issue.
Any ideas?
