Hi all

I'm working on a custom outlook addin where I need to subclass the appointment window. This works basically pretty well following the principles mentioned in the following ariticle:

I'm struggeling by getting the handle to the social connector within the new appointment window. See Screenshot

I've tryied out a few approaches (FindWindow, FindWindowEx, EnumChildWindow) but none of them gave me the correct handle.

Here you can find a small addin project to have a quick look at it.

Btw. the social connector is only displayed if you directly create a meeting request e.g. go to the calendar, right click --> New meeting request

Any thoughts on this?

Regards,
Lukas
