Good thinking, Michael, I hadn't thought of IMAP or any HTTP based stores
where the PST is just a mirror into that server. None of those would support
persisting categories. Nor would a BCM store unless the BCM database
supported synching up categories.

Is your default mail account by chance IMAP? That could explain it as IMAP
doesn't support categories. Outlook won't try to write the categories to
the
Master Category List until you close it, and that's when they get lost.

Other ideas: you're connected to a mailserver other than Exchange, or you
don't have the permission to write to the default calendar of the mailbox.

Did you test already whether or not you can add categories to the mailbox
by
using Outlook's Categorize dialog?
