But rows_count is 0, although Outlook have connected AD with several
contacts in it.

What's wrong ?

Look through your address book containers using OutlookSpy/MFCMAPI or
else take out the restriction and dump those properties for all the
rows and see what's not matching up. You're looking for a container
which is probably called "Global Address List", but querying by name
is unwise.
