System and method for in-place editing of an electronic mail message using a separate program

An email client invokes a DocObject-enabled mail note to display an email message and related features of the user interface. The mail note, which is a DocObject container, creates a DocObject server by invoking a DocObject-enabled word processor. The mail note provides a view port in which the word processor displays and edits the body of the email message. The word processor provides its formatting and editing features in the context of the mail note. OLE menu merging provides both email and word processing interoperability while editing the message. Programming interfaces between the mail note and the word processor allow the mail note to translate message data back and forth between the word processor's format and the format imposed by the email client. This ensures that messages created with the word processor can be read by other email clients.
