'Unavailable critical extension' is returned when using Outlook 2003 against a W

W

Wayne Alston

with XP and Outlook 2003, Tools/E-mail Accounts LDAP
directory pointing to a W2K3 AD, after about 20 seconds,
the error 'Unavailable critical extension' is returned,
however I can still use Advanced and can succesfully
find the desired recipients..

When using NT4 and Windows 98, using the same LDAP
directory settings, the search is instantaneous and
without the error

Any clues as to why and how to fix.. I have tried this
with 2 different ADs' with the same error :-(

Thanks
Wayne
