Symptoms

When you generate an offline address book (OAB) on a server that is running Microsoft Exchange Server 2003 Service Pack 2 (SP2), the following Warning event is logged in the Application event log:

Event Type: Warning
Event Source: MSExchangeSA
Event Category: OAL Generator
Event ID: 9320
Description: OALGen could not generate full details for some entries in the offline address list for address list '\Global Address List'. To see which entries are affected, event logging for the offline address list generator must be set to at least medium.

- Default Offline Address List

For more information about this event, follow these steps:
  1. Start Exchange System Manager.
  2. Locate the Exchange server that is responsible for the offline address book generation.
  3. Right-click the Exchange server, and then click Properties.
  4. Click the Diagnostics logging tab.
  5. In the Services list, click MSExchangeSA.
  6. In the Categories list, click OAL Generator, click Medium, and then click OK.
  7. If there are enough server resources available, rebuild of the offline address list. If there are not enough server resources available, wait until the next scheduled run of the offline address list.
Additionally, the following event is logged in the Application event log when you generate an offline address book:

Event Type: Warning
Event Source: MSExchangeSA
Event Category: OAL Generator
Event ID: 9359
Description: OALGen truncated or dropped properties for entry 'User Name' in address list '\Global Address List' because they exceeded the configured size limits for the version 4 offline address list. The affected MAPI ids are: 800f.

- Default Offline Address List

Cause

The new version of OAB in Exchange Server 2003 SP2 is OAB version 4. In OAB version 4, the Exchange server enforces limits to make sure that OAB version 4 does not become too large. For example, if the Exchange server finds an attribute that exceeds the default limits or that exceeds the limits that are set by an administrator, the attribute is removed from the offline address book. Additionally, event ID 9320 is logged to indicate that information has been limited in the offline address book. When the diagnostic level is set to Medium or a higher level, event ID 9359 is logged to identify the display name and the MAPI ID of the property that was limited.

When an attribute is removed, the Exchange server adds an indicator to let Microsoft Outlook know that some properties were removed. Microsoft Office Outlook 2003 Service Pack 2 (SP2) treats the removed properties as "not present" in the record that owns the properties. Additionally, the Exchange offline address book generation process makes sure that when the record that owns the properties retrieves the attributes that Outlook requires to send messages, the attributes are never removed from the offline address book.

Resolution

To interpret event ID 9359, you must convert the MAPI ID to a property name. MAPI IDs are the properties of the offline address book that contain user data. In event ID 9359, the property name of MAPI ID 800f is PR_EMS_AB_PROXY_ADDRESSES. This value contains the proxy addresses, or e-mail addresses, for the user. In this scenario, the number of e-mail addresses has exceeded the specified limit.

Additionally, you may see the following MAPI IDs when you interpret event ID 9359:
  • 0x3A22 = PR_USER_CERTIFICATE
  • 0x3A70 = PR_USER_X509_CERTIFICATE
Typically, these are the properties that may contain more data about the user.

Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base:

The following table contains the four property types that you can limit. Additionally, the table contains the default values and the lower limit values that you can configure in the registry.

Registry valueDescriptionLower limit value (bytes)Default value (bytes)
OAL V4 String LimitSingle-valued text-based Active Directory properties such as Display name, Telephone number, and Office location323400
OAL V4 String Multi Value LimitMulti-valued text-based Active Directory properties such as E-mail addresses and Business and home telephone51265536

OAL V4 Binary Multi Value LimitMulti-valued binary-encoded Active Directory properties such as userSMIMEcertificate and userCertificate204865536
To add a value, follow these steps:
  1. Click Start, click Run, type regedit, and then click OK.
  2. Locate and then click the following subkey:
    HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\MSExchangeSA\Parameters
  3. Right-click Parameters, point to New, and then click DWORD Value.
  4. Type the name of the value that you want to configure.
  5. Double-click the value that you named in step 4. In the Value data field, type an appropriate value for the maximum attribute size in bytes. In the Base area, click Decimal.
  6. Click OK.
  7. Quit Registry Editor.
Note These values apply only to the new offline address book format that is generated by Exchange Server 2003 SP2 and that is used by Outlook 2003 SP2 and later versions of Outlook.

These parameters are read immediately during the next offline address book generation process. You do not have to restart of the System Attendant service for the changes to take affect.
