DOLS and Offlineline Addressbook

Hi,

I have a problem with DOLS, i have configured DOLS and its working fine. The problem is i am not able to take my directory catalog offline. Presently using DOLS i can reaf email offline but i cannot send or forward as no addressbook available.

I tried $DOLSDirectoryCatalog=nameofcatalog.nsf (nameofcatalog being the actual name of the catalog) server notes.ini parameter by no lock.

Can anyone helpme with to make my Directory catalog offline.

Thanks for your valuable time.
