Thanks for the reply, Al. Not sure what you want with the first question, but I'll try to be as concise as possible. I checked the properties for the public folders and the OAB Version 2 is in the instances folder. The client permissions for the under the folders EX:/o=Organization/ou=Site, OAB Version 2, which is the OFFLINE ADDRESS BOOK, and OAB Version 2 folders, have client permissions of owner for the exchange administration account and reviewer for anonymous. There is nothing under the OAB Version 2 folder. I found an article that said to use Mdbvu32.exe to locate the Offline Address Book, but I'm running 5.5 and this program doesn't appear to be on that CD. Laptop users just get an error message in the synchronization log for the Offline Address Book when they try to do a full synchronization: Microsoft Exchange offline address book 0X8004010F This was working up until Thursday when I became aware of it. I haven't made any changes -----Original Message----- From: Mulnick, Al [mailto:Al.Mulnick@xxxxxxxxxx] Sent: Monday, October 20, 2003 13:30 To: [ExchangeList] Subject: [exchangelist] RE: Laptop users are unable to download offline ad dress book http://www.MSExchange.org/ What exactly is the setting on the Exchange server? There's more buttons than that, but curious what you have setup. Also, what happens when you remove the OAB from the laptop user and then try to download again? Was this working before and then stopped? If so, what changed???

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.
