Re: Popup Outlook contact makes the WinForm stuck and frozen
 

You need to run the contact launching code in a new thread, or consider using a background worker to start your FindContactEmailByName method.

Here's a tutorial on the background worker:

Basically, when you show a new form like that, the "owner" form that launches the contact.Display(true) call blocks until the contact is closed, or control is returned to the calling form.
