Yep, just solved this one.
The problem appears to occur (among other instances) when using Outlook 2003 to
read PST files from earlier versions of Outlook.
I eventually fixed the problem by:
- starting a new outlook file, with no contents
- save it
- import the old PST file into the new one
When "imported" the old data gets restructured into the new format.
Unfortunately the new file (at least in my case) was significantly larger than
the old one. I suspect to prevent this problem from recurring, you should
allow Outlook to auto-archive (so your PST file doesn't get overly large).
I hope this is helpful.
