MOM Rule Name

Failed to find source directory or file.

Explanation

This event indicates that Microsoft Exchange File Distribution service did not find an offline address book file.

  • If MSExchangeFDS event 1021 is logged, the ExchangeOAB directory could not be found on the server that is running Microsoft Exchange Server. This is typical if Oabgen.dll (referred to as OABGen) has never been run on this server. The Microsoft Exchange File Distribution service (MSExchangeFDS) will connect to the ExchangeOAB directory for offline address book (OAB) files so that these files can be distributed to Microsoft Outlook clients. If MSExchangeFDS cannot find the ExchangeOAB directory, OAB distribution to Outlook clients may not work. This event may also occur if MSExchangeFDS does not have the necessary permissions to access the ExchangeOAB directory.

  • If MSExchangeFDS event 1022 is logged, the Microsoft Exchange File Distribution service did not find an offline address book manifest file (oab.xml). The File Distribution service requires this file to synchronize offline address book files between Exchange servers that have the Mailbox server role and Client Access (CAS) server roles installed.

    This event may occur if either of the following conditions is true:

    • The offline address book manifest file (oab.xml) has not been generated yet. This file is generated when the corresponding offline address book is updated. By default, every offline address book is updated daily at 5:00 AM.

    • The Exchange Servers group does not have Read permission on this manifest file (oab.xml).

      Note   If the corresponding offline address book update has yet to run, you may ignore this event. Otherwise, see User Action.

      Note   The offline address book GUID that follows the ExchangeOAB file share in the event description indicates the corresponding offline address book.

User Action

To resolve this warning, do one of the following:

  • If MSExchangeFDS event 1021 is logged, on the Exchange server that logged this event, open the directory where Exchange has been installed, for example, C:\Program Files\Microsoft\Exchange Server, and make sure that the ExchangeOAB directory exists. If it does not, run the following command from Exchange Management Shell:

    Update-OfflineAddressBook "Default Offline Address List"

    If the ExchangeOAB directory already exists, make sure that it is shared and that the Exchange Servers group has Read permissions assigned.

  • If MSExchangeFDS event 1022 is logged, make sure that Exchange Servers group has Read permission on the oab.xml file specified in the event description. Then, regenerate the manifest file by doing the following procedure:

    • Note the offline address book GUID that follows the ExchangeOAB file share in the event description.

    • Run the following Exchange Management Shell command:

      Update-OfflineAddressBook -Identity <offline address book identifier>

      Note   In this command, replace <offline address book identifier> with the GUID that you determined in the previous step.

    • Restart the Microsoft Exchange File Distribution service from the Microsoft Windows Services console on the Exchange server that logged this event.
