Hi Jerry!
I should have an article specifically for this coming shortly but in the
meantime have a look at this page on the Entourage Help Page
<
http://entourage.mvps.org/accounts/exchangeatwork.html>. Skip from #3
to #7 and continue from there.
For the email server you'll want to use the web address you'd use for
your Outlook Web Access server such ashttp://webmail.domain.com.
For the public folder server you'll want to use the web address you'd
use for your Outlook Web Access server followed by "/public" such as
such ashttp://webmail.domain.com/public.
LDAP lookups typically are not possible through OWA.
Hope this helps! bill
