The Note Object Protocol allows a user to store in his mailbox a simple text note (that is, text with minimal formatting) that functions as the electronic equivalent of a paper sticky note. To represent the sticky note, this protocol defines a Note object. The properties that are specific to a Note object contain information about the background color, window location, and size of the note. A Note object is stored in a Folder object. The Note Object Protocol also specifies how a Note object is created and manipulated.
The Note Object Protocol extends the Message and Attachment Object Protocol, described in [MS-OXCMSG], in that it defines new properties for a Message object and adds constraints to the existing properties of a Message object.
