Les -

    Thanks for the explanation.  Unfortunately it doesn't appear to help my 
situation.  We do not run a mail server at our office.  Our incoming mail 
service is provided by a third party provider.  Our outgoing mail service is 
directed to the mail server at our local DSL provider.  All incoming and 
outgoing mail for the PC clients in our office therefore does not go through 
our server.  My employee would love to be able to use her regular Windows 
Mail client when she is accessing the internet from wireless connections at 
hotel meeting rooms.  If anyone has any other suggestions for me you can 
send them directly to me and we can take this off-list, since we are clearly 
off topic now.  Thanks.
