Forgive the reposting, but up until this morning I would have considered no reponses the result of no one else having the answer either. Now I have to question whether my question is "too basic" to be answered by those more experienced than I. Can anyone provide a suggestion on where to proceed, please. -----Original Message----- From: Maglinger, Paul Sent: Monday, October 20, 2003 08:14 To: 'Exchangelist server' Subject: Laptop users are unable to download offline address book For some reason my laptop users are unable to download the offline address book. After trying, when they open it, it is blank. I have selected in Exchange to have the OAB generated from the Global Address book, that didn't work. I have also created another recipients container and pointed OAB generation to that container, still no go. Running Exchange 5.5SP4 on Win2K server. Could the OAB on the server be corrupt, and is there a way to deleted the OAB that was generated on the server and recreate it? I can find nothing on this subject except deleting OABs on the laptops themselves, nothing on the OAB generated on the server. Paul Maglinger
