Summary

When you use Microsoft Office Outlook 2003, Microsoft Office Outlook 2007, or Microsoft Office Outlook 2010 in Cached Exchange Mode, Outlook verifies and resolves the names of e-mail recipients with the Offline Address Book. The process of resolving e-mail addresses with similar fields, such as the DisplayName, is called Ambiguous Name Resolution (ANR).
  • displayName
  • mail
  • givenName
  • legacyExchangeDN
  • mailNickname
  • physicalDeliveryOfficeName
  • proxyAddresses
  • name
  • sAMAccountName
  • surname (last name)
The ANR that is used by the Offline Address Book indexes the following fields for matching names:
  • mailNickname (Alias)
  • displayName (Display Name)
  • physicalDeliveryOfficeName (Office)
  • surname (last name)
For OAB version 4, the ANR that is used by the Offline Address Book indexes the following fields for matching names in the OAB:
  • mailNickname (Alias)
  • displayName (Display Name)
  • physicalDeliveryOfficeName (Office)
  • sn (Last Name)
  • givenname (First name)
  • SMTPaddress (email address)

Workaround

To work around this behavior, add a registry key that forces Outlook to use the online Global Address List to resolve ambiguous names or e-mail aliases.

Note When you are using a Cached mode profile with the ANR Include Online GAL value set to 1, Outlook will resolve proxy addresses for a user. For example, Marcelo Santos has the following e-mail addresses in his Active Directory account: 

Primary SMTP address - msantos@contoso.com 
secondary smtp address - marcelosantos@fourthcoffee.com 
custom - marcelo:santos 
SIP - msantos@contoso.com 

To resolve these proxy addresses enter partial addresses. For example, the following proxy addresses will be successfully resolved for the above example user:

smtp:marcelosantos  
smtp:marcelosantos@fourthcoffee  
SIP:msantos@contoso  
custom:marcelo

You can tell the name resolved successfully from the GAL because if you double-click the resolved name the dialog box with all of the user's Active Directory attributes (in the GAL) is displayed. However, you cannot enter the complete addresses for proxy address that end with a top-level domain. For example, if you enter the following proxy addresses they will not be resolved for the above example user:
smtp:marcelosantos@fourthcoffee.com  
SIP:msantos@contoso.com 

You can tell the name was not resolved successfully from the GAL because if you double-click the resolved name the "E-mail Properties" dialog box is diaplayed. This dialog box does not display any Active Directory attributes, only Display name, E-mail address, and E-mail type.

To have us force Outlook 2003, Outlook 2007, Outlook 2010 to use the Global Address Book, go to the "Fix it for me" section. If you prefer to add this key yourself, go to the "Let me fix it myself" section.

Fix it for me

To force Outlook 2003, Outlook 2007, or Outlook 2010 to use the Global Address Book to resolve ambiguous names or e-mail aliases when you create an e-mail message instead of using the Offline Address Book automatically, click the Fix this problem link. Then, click Run in the File Download dialog box, and follow the steps in this wizard.

Note there will be Remote Procedure Calls (RPC) incurred whenever the following conditions are true:
  • A name is resolved in the To box of an e-mail message.
  • An e-mail message is sent.
  • A reply is sent to a one-off SMTP address.

Let me fix it myself

In Outlook, you can use the new registry key named ANR Include Online GAL to set the address book that Outlook uses to resolve ambiguous names or e-mail aliases. You can use one of the following registry entries to set the ANR Include Online GAL registry key manually or with Group Policy:

In Outlook 2003

Manual Setting:
HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Outlook\Cached Mode
Group Policy Setting:
HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\11.0\Outlook\Cached Mode
Parameter:ANR Include Online GAL
Type: REG_DWORD
Value: 0 or 1

The value 0 is the default value for the Offline Address Book. If the value is set to 0, Outlook 2003 uses the Offline Address Book to resolve ambiguous names or e-mail aliases when you create an e-mail message.

If the value is set to 1, Outlook 2003 uses the Global Address Book to resolve ambiguous names or e-mail aliases when you create an e-mail message instead of using the Offline Address Book. This means that there will be Remote Procedure Calls (RPC) incurred whenever the following conditions are true:
  • A name is resolved in the To box of an e-mail message.
  • An e-mail message is sent.
  • A reply is sent to a one-off SMTP address.
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:

You can manually add the ANR Include Online GAL registry key to the registry.

Follow these steps, and then quit Registry Editor:
  1. Click Start, click Run, type regedit, and then click OK.
  2. Locate and then click the following key in the registry:
    HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Outlook\Cached Mode
  3. On the Edit menu, point to New, and then click DWORD Value.
  4. Type ANR Include Online GAL, and then press ENTER.

The value 0 is the default value for the Offline Address Book. If the value is set to 0, Outlook 2007 uses the Offline Address Book to resolve ambiguous names or e-mail aliases when you create an e-mail message.

If the value is set to 1, Outlook 2007 uses the Global Address Book to resolve ambiguous names or e-mail aliases when you create an e-mail message instead of using the Offline Address Book. This means that there will be Remote Procedure Calls (RPC) incurred whenever the following conditions are true:
