2.2.4.4.4 MailAttachment Structure

  • Article

The structure of "MailAttachment N" storage depends on the way the contents of the attachment can be accessed. The different ways are specified by the PidTagAttachMethod property ([MS-OXCMSG] section 2.2.2.9). A rights-managed email message MUST allow only the following values for the PidTagAttachMethod property:

  • afByValue

  • afEmbeddedMessage

  • afOle

Treatment of each type of attachment is described separately in section 2.2.4.4.4.1 through section 2.2.4.4.4.3.
