I can't access the kerberos security option.
I right click on 'Outlook Today'...the little icon of a house on the top left
above all the email folders.
I am given the option of 'Standard, Advanced, Web or Customize...'. When I
click
on 'Advanced' it removes the bar along the top of Outlook 2003, including the
little house 'Outlook Today'?

Any ideas please?
