Default View for public for Public Folder postings

[Toto]

HI.
I'm getting, JUST FOR ONE of my Outlook users, the
following behaviour: when she opens Outlook she has, by
default, configured the "Messages with AutoPreview" option
as the "Current View" for public folder's postings.

IS there any configuration option that has to do with
that ? How can I set up the "Current View" setting for ALL
PFs ?

Thanks a lot in advance for any help you can provide.
