Inline Attachments

Inline attachments are attachments that are rendered by clients within the body of the message. Clients SHOULD NOT create inline attachments if the best body text format is plain text. MIME writers SHOULD ignore indications that an attachment is inline for plain text messages by ignoring the presence of these properties on the Attachment object:

  • PidTagAttachFlags ([MS-OXCMSG] section

  • PidTagAttachContentId ([MS-OXCMSG] section

  • PidTagAttachContentLocation ([MS-OXCMSG] section

Likewise, clients SHOULD NOT designate attached Message objects as inline, and MIME writers SHOULD NOT<77> treat attached Message objects as inline.
