Exchange 2016 CU10 DAG replication fails RRS feed

  • Question

  • Hi,

    got two Exchange 2016 CU10 and one CU9, 2xCU10 configure with DAG and CU9 is going to be decommissioned.

    In logs I can see this:

    Log Name:      Application

    Description:

    %2

    and then another one with the same GUID:

    Log Name:      Application

    Date:          6/08/2018 8:48:10 PM

    Description:
    The Microsoft Exchange Mailbox Replication service was unable to process jobs in a mailbox database.
    Database: 003
    Error: Couldn't find system mailbox 'ac9acd0c-3833-4975-974f-d29133c40d32' in Active Directory.


    Where: ac9acd0c-3833-4975-974f-d29133c40d32 is in fact my database and not a mailbox.

    These are my arbitration mailboxes:

    [PS] C:\Windows\system32>Get-Mailbox -Arbitration | ft Name

    Name
    ----
    SystemMailbox{1f05a927-0118-4a12-b5ad-5223faa98f32}

    SystemMailbox{8cc370d3-822a-4ab8-a926-bb94bd0641a9}

    I tried restarting, re-creating arbitration mailboxes, restarting ADs, etc. nothing helps.

    Does anyone know what to do in this situation?

    Many thanks.
