You may encounter an issue with Exchange Server 2007 organisations that have been migrated from previous Exchange versions where the Default Offline Address List cannot be enabled for web distribution, even after the OAB has been moved to an Exchange Server 2007 server.

In the Exchange Management Console the check box to enable web distribution is greyed out.


To resolve this issue use the Set-OfflineAddressBook cmdlet to apply the mandatory properties to the OAB object.

[PS] C:\>Set-OfflineAddressBook "Default Offline Address List" -ApplyMandatoryProperties

When viewed in the Exchange Management Console the check box is now available.


You can now tick the box and add OAB virtual directories for web distribution.

    Is there a way to change the order in which the address book list shows up? User see the Demo Assets first instead of the Default Global Address List

    [PS] C:\>Get-OfflineAddressBook | fl Name,addresslists
    Creating a new session for implicit remoting of “Get-OfflineAddressBook” command…

    Name : Default Offline Address List
    AddressLists : {Demo Assets, Conference Rooms, AMI Personnel, All Users, All Rooms, All Groups, All Contacts, *Link Only, Public Folders, Default Global Address List

        I have not moved the OAB to new server that is Exchange 2010 ( in console, I can see OAB generation server is still pointing to Exchange 2003)

        How to move steps can help… before that I wish to know what will happen to users on Exchange server 2003 if they try to download OAB (after moving it to new server)
