See http://www.outlookcode.com/d/propsyntax.htm for syntax to access
controls on forms. If you want a user property use the UserProperties
collection of the item and get the UserProperty you want.

www.outlookcode.com in general has lots of information about Outlook coding
and COM addins.

I'm newbie with programming MS Outlook Plug-in.

Any one can show me how can I access to the custom field, control on a
custom form in Outlook 2003 using C# code? Or any resource that can help
me
do with this.

Thanks in advanced.
