Ask in an Outlook Express newsgroup like
news://msnews.microsoft.com/microsoft.public.outlookexpress.general or a
newsgroup dedicated to the sync software you're using.

This newsgroup is for support of Outlook 97, 98, 2000, 2002 & 2003 from the
Office family for Intel PCs. For Outlook Express (OE) support try posting in
one of these newsgroups:
microsoft.public.inetexplorer.ie4.outlookexpress for OE 4.x
microsoft.public.windows.inetexplorer.ie5.outlookexpress for OE 5.x
http://support.microsoft.com/newsgroups/default.aspx?ICP=GSS3&NewsGroup=microsof

http://support.microsoft.com/newsgroups/default.aspx?ICP=GSS3&NewsGroup=microsof
t.public.internet.outlookexpress.mac&SLCID=US&sd=GN&id=fh;en-us;newsgroups

If those groups aren't carried on the news server that's carrying this group
try using msnews.microsoft.com (MS's public news server that's the source
for all the microsoft.public newsgroups). The links under the newsgroup
references are for use with MS's web newsreader (not exactly the best way to
post but it works for some people)
