Rule Path

Rule Name

OABGen encountered an error while generating versions 2 and 3 of an offline address book (OAB). Not all versions of this OAB will be published.

Explanation

For Microsoft Outlook clients that are running Office Outlook 2003 Service Pack 1 (SP1) or earlier, if an Exchange server that is running Exchange Server 2003 Service Pack 2 (SP2) determines that a differences download is more efficient, and if a differences file cannot be generated on a server that is running Exchange 2003 SP2, Exchange Server will not automatically force a full offline address book (OAB) download. Instead, Exchange logs MSExchangeSA event 9360. MSExchangeSA event 9360 indicates that it was unable to produce a differences file and will not produce a full OAB file.

Note:
When this event is logged, the users running Outlook 2003 SP1 or earlier will not be able to receive OAB updates until the problem is corrected.

The offline address list has not been updated, so clients will not be able to download the current set of changes.

User Action

To resolve this error, do one of the following:

  • In Event Viewer, examine the Application log for events that occur before and after MSExchangeSA event 9360. These related events may help you discover the reason that Exchange cannot generate a differences file for your Outlook clients that are running Outlook 2003 SP1 or earlier.

  • Perform the following procedure to generate a full OAB download file when a differences file cannot be generated:

    Caution:
    Incorrectly editing the registry can cause serious problems that may require you to reinstall your operating system. Problems resulting from editing the registry incorrectly may not be able to be resolved. Before editing the registry, back up any valuable data.
    1. On the Exchange server, start Regedit.exe.

    2. Open the following registry key:

    3. HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\MSExchangeSA\Parameters

    4. Right-click Parameters, point to New, and then click DWORD Value.

    5. For the new value name, type OAL post full if diff fails.

    6. Double-click OAL post full if diff fails. In Value data, type 1. Click OK.

    7. Close Regedit.exe.

For information about how to edit the registry, see Microsoft Knowledge Base article 256986, Description of the Microsoft Windows Registry.
