INTRODUCTION

Several 2007 Microsoft Office applications provide an API that lets a mail client interface with 2007 Office applications when the API is implemented by the mail client. This API provides an integrated experience for sending a copy of a 2007 Office document. If the default mail client implements the API, you can use the Microsoft Office Outlook 2007 mail envelope experience directly in 2007 Office applications.

MORE INFORMATION

For you to use the mail envelope experience directly in 2007 Office applications, the mail client must implement the following interfaces.

IMsoEnvelope

punk
[in] Not used. The value that is used should be NULL.
