Outlook cannot recognize Address from Global Address List

This is just simple and need to change registry setting for outlook.

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.

[u]In Outlook 2007

Manual Setting:
HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Outlook\Cached Mode
Group Policy Setting:
HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\12.0\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 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.
