Exchange 2016 CU10 bug/and/or related to latest round of september patches (GAL errors out on outlook 2010/2016)

    Question

  • I first wrote to reddit.

    https://www.reddit.com/r/exchangeserver/comments/9idpuj/outlook_address_book_the_operation_failed/



    details:

    Between Sept 21-23 I've installed couple of patches

    on windows 10 clients 

    KB4100347: Intel microcode updates

    September 17, 2018—KB4464218 (OS Build 17134.286)



    on exchange server 2016 cu 10.
    2018-09 Cumulative Update for Windows Server 2016 for x64-based Systems (KB4457127)

    2018-09 Update for Windows Server 2016 for x64-based Systems (KB4091664)

    I also happen to have installed exchange server 2016 CU 10 from CU7 on 8/9/2018

    ---

    so users on outlook 2016 complain when they open the address book, they get "the operation failed" pop up.
    event viewer shows no related events.

    I tested myself on outlook 2010 as well with same results.

    we don't use cache mode, so i eventually excluded OAB generation issues. besides, i can see all my recipient lists on OWA

    after realising that some address lists work and some don't . i found out that if an address lists contains more than 18 recipients, it fails to load in outlook. the GAL thus will always fail to load

    as a work around i broke down my larger address lists into multiple lists with less than 18 recipient each

  • Hello,

    The problem is the update KB4457127.
    With Exchange 2010, there is the same problem.

    You have to uninstall the update on the domain controller again.

  • ok done.

    i have 2 dc, i've uninstalled from one and rebooted, I  have not rebooted the 2nd dc

    KB4457127 remains installed on exchange server.

    problem is "fixed" at the moment.

  • I can confirm that uninstalling KB4457127 on your domaincontrollers is the solution for the GAL issue.

    (Windows 2016 Domain controllers and Exchange 2016 CU10 on W2016)
