Outlook 2003 SP2 and above creates duplicate diary entries when synchronising your Outlook diary with your eLink Agenda. This occurs due to a change in how Microsoft Outlook handles meetings, see microsoft knowledge base article: http://support.microsoft.com/kb/899919/en-us
By default, this new meeting acceptance behavior is enabled in Outlook 2003 SP2 and later. However, the behavior can be disabled or re-enabled by using the following registry data on the Outlook client:
Key: HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Outlook\Options\Calendar
DWORD: DisableMeetingRegeneration
Values: 1 = revert to the pre-SP2 behavior; 0 = use the new SP2 behavior
DWORD: DisableMeetingRegeneration
Values: 1 = revert to the pre-SP2 behavior; 0 = use the new SP2 behavior
Note Without this registry data, Outlook 2003 uses the default SP2 or later service pack behavior.
In Outlook 2007, this registry key is available in the Office deployment tools.
