You can't add a .NET custom control to an Outlook form. All controls on
Outlook forms are either members of the Forms 2.0 library or are custom
ActiveX controls. You also shouldn't use the OLK* controls on a custom form
other than in a form region, they aren't tested for that and will cause
weird problems.

It doesn't matter whether or not you're using VSTO, you access any control
on a form the same way whether or not it's a custom control.
item.ModifiedFormPages("myPage").Controls.Item("my Control").
