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: techsupport@weonlydo.com <Technical Support>

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

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