is your public folder db available?Roy Mayo | MCTS MCSE | USA

I'm pushing the OAB only via web browser and disable the option for Public folder. Yes Public Folder DB is availabe but permissions are set for users on PF.

HI, The error says that "A server (URL) could not be Located" Check whether proper URL is in place for users to locate while they download OAB. For more information check this article. http://technet.microsoft.com/en-us/library/bb123710.aspx I hope this helps. Sunder

What happens if you try to rebuild the OAB using te following Powershell command: Update-OfflineAddressBook –Identity “Default Offline Address List” NOTE: This will generate the Default Offline Address List. Again by default you will not see any output if the Offline Address List has been generates successfully. OPTIONAL COMMNAD: You can also run Update-OfflineAddressBook –Identity “Default Offline Address List” -vb to output the information in verbose mode.
