Holds name of the header.

A String value.  

object.Name [= value]

The Name Property syntax has these parts:

Each header in email message is defined with Name and Value parts. For example, most common

From: "Technical support" <techsupport@weonlydo.com>

header has two parts: 'From' is header Name, and "Technical support" <'techsupport@weonlydo.com>  is header Value.

You can freely change both of these properties, but try not to violate mail specifications.
