I have a profile configured with exchange as the default message store, an
instance of a unicode pst (Personal Folders) and an instance of a wrapped
unicode pst (Steve Griffin's code). All three seem to work fine using
unicode. I can change the default email delivery location from the exchange
mailbox to the unicode pst and that also seems to work fine. But if I try to
select the wrapped pst as the default location, I get an error dialog from
"Account Manager". It reads:

The Personal Folders file (.pst) you selected does not match the format of
your Offline Folder file (.ost). To correct this, select a Personal Folders
file that supports Unicode or disable the use of offline folders.

Any idea why I'm getting this if both the pst and the wrapped pst work with
unicode?
