Exchange 2013 - cannot download offline address book

Jack Chuong 846 Reputation points

Hi all, My environment : 3 Exchange 2013 servers (Mailbox + CAS roles) CU23 in 1 DAG
Last week, after applied security update KB5000871 , MS Outlook cannot download offline address book anymore, users get error "8004010F". Global address book is ok, so new created users can be found when using OWA , cannot be found when using MS Outlook.
Test-Email AutoConfiguration doesn't show OAB in result


I look into OAB virtual directory (in ECP) and see that "External Url" is empty , I filled "External Url", should I restart IIS to make it effect ?

I did some search and found some guide said that "GlobalWebDistributionEnabled" , "WebDistributionEnabled" should be set to True and "VirtualDirectories" should be said to null. Should I do this ?

    Hi @Jack Chuong ,
    According to my research:
    1.Please try to re-create a outlook profile for the user's mailbox in question.

    2.Regarding the parameters you mentioned:

    1. About the “GlobalWebDistributionEnabled” parameter is $false by default. But in Exchange 2013 CU7 or later, Microsoft recommend that you use the value $true for this parameter. The Client Access services on any Mailbox server can proxy incoming OAB download requests to the correct location.

    2) About the “VirtualDirectories” parameter, In Exchange 2013 CU7 or later, Microsoft recommend that you set this parameter to $null, and then set the GlobalWebDistributionEnabled parameter to $true. Please noted that to use this parameter, the value of the “GlobalWebDistributionEnabled” parameter must be &false.

    3) After changing the parameters, please run the iisreset in the Run start as Administraotr to restart the IIS.

    4) To prevent wrong changes, please back up your current settings before making changes.
    For more information about these parameters, you could refer to: Set-OfflineAddressBook

    3.Please run the following command to generation of OAB, then check whether the OAB generation is normal under the path %ExchangeInstallPath%\ClientAccess\OAB\<ObjectGuid> file.

    Get-OfflineAddressBook | Update-OfflineAddressBook  

    In addition, after the OAB download fails, are there any related error logs in event viewer? If so, please share with us, but please pay attention covring your personal information.

    Open the Exchange Management Shell.
    Run the Get-OfflineAddressBook cmdlet to obtain a list of available offline address books.
    Run the Set-MailboxDatabase cmdlet to configure the offline address book for the database.

    I tried :
    set oab virtualdirectory url
    Get-OabVirtualDirectory | fl Identity,url

    Identity    : ex01\OAB (Default Web Site)
    InternalUrl :
    ExternalUrl :
    Identity    : ex02\OAB (Default Web Site)
    InternalUrl :
    ExternalUrl :
    Identity    : ex03\OAB (Default Web Site)
    InternalUrl :
    ExternalUrl :

    Restart IIS website , recycle MSExchangeOABAppPool on 3 exchange servers
    Try Updating OAB using the cmdlet: Update-OfflineAddressBook “Default Offline Address Book” on 3 exchange servers
    Try restart Microsoft Exchange Mailbox Assistant service on 3 exchange servers
    Nothing works.

    Remains solutions :
    Use cmdlet "Set-OfflineAddressBook" to set "GlobalWebDistributionEnabled" , "WebDistributionEnabled"
    Create a new Offline address book and assign it to all the databases
    Please give me some advice, thank you very much.

    Hi Lucas,
    I tried command to generation of OAB and verified the OAB generation is normal under the path %ExchangeInstallPath%\ClientAccess\OAB\<ObjectGuid>


    This happen to all users, not specific user.
    I will try “GlobalWebDistributionEnabled” and “VirtualDirectories” and feedback later , but I have a concern about Autodiscover virtual directory url , here is my settings :

    Get-ClientAccessServer | FL *iden*,*uri*  
    Identity                       : ex01  
    AutoDiscoverServiceInternalUri :  
    Identity                       : ex02  
    AutoDiscoverServiceInternalUri :  
    Identity                       : ex03  
    AutoDiscoverServiceInternalUri :  
    Get-AutoDiscoverVirtualDirectory | fl identity,internalurl,externalurl  
    Identity    : ex01\Autodiscover (Default Web Site)  
    InternalUrl :  
    ExternalUrl :  
    Identity    : ex02\Autodiscover (Default Web Site)  
    InternalUrl :  
    ExternalUrl :  
    Identity    : ex03\Autodiscover (Default Web Site)  
    InternalUrl :  
    ExternalUrl :  

    Should I Set-AutoDiscoverVirtualDirectory interal and external url for 3 exchange servers ? I read some docs said that they shoud be null by default.
