on older versions (pre 4.0.3) thats where you would have to look to see if the sharing add-in was available. with your version, the add-in is not supposed to be listed in outlook, but only in the registry.
if the extension is there and the add-in has load-behavior set to 3, you should be good to go. you can verify the sharing add-in is loaded by the existance of the 'Sharing' tab in the file->properties dialog. |
