Outlook using Univention as LDAP contacts / Address book search problems

Good morning, having an odd issue trying to configure LDAP address book on Outlook client.

Settings are correct but I cannot search unless using the “Advanced Find”. Putting any characters in the Display name or any other field returns matches, but it will not browse… I’ve tried different base, RO users and authenticated users with the same results.

Is anyone successfully using outlook and LDAP address book connected to UCS ?? Is it possible to auto-complete or auto-search the directory?
