When using Outlook 2007 or 2010 you can bring up the Advanced Find dialog by pressing Crtl+Shift+F.
I have performed advanced queries against Outlook contact items and calendar items, but would like to show Outlook's native dialog box for users to perform more advanced searches instead of trying to recreate that dialog box within my app.
I've searched, but have been unable to find details on how to show that dialog box from within a .NET application.
