Control the loading of the Conferencing Add-in for Outlook

A COM add-in has to register itself with each Office application in which it runs. To register itself with a particular program, the add-in should create a subkey by using its ProgID as the name for the key, in the following registry locations:
  • HKEY_CURRENT_USER\Software\Microsoft\Office\<OfficeApp>\Addins\<ProgID>
  • HKEY_LOCAL_MACHINE\Software\Microsoft\Office\<OfficeApp>\Addins\<ProgID>
The add-in can provide values at these key locations for both a friendly display name and a full description. In addition, the add-in should specify its desired load behavior by using a DWORD value called LoadBehavior. This value determines how the add-in is loaded by the host program.

The Conferencing Add-in for Outlook uses the LoadBehavior values of 2 for disabled and 3 for enabled.

If the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\Outlook\Addins\Microsoft.LiveMeeting.Addins - LoadBehavior registry entry is set to 3:
  • In the COM Add-ins dialog box, the Microsoft Conferencing Add-in for Outlook entry will be selected.

If the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\Outlook\Addins\Microsoft.LiveMeeting.Addins - LoadBehavior registry entry is set to 2:
  • In the COM Add-ins dialog box, the Microsoft Conferencing Add-in for Outlook entry will not be selected.

The registry settings for COM Add-ins can be applied at the level of the computer or the account of the user who is signed in. Registry settings that are applied at the level of the computer will override the registry settings that are applied at the level of the signed-in user.
