Adding Rendering Information to Formatted Text

Applies to: Outlook 2013 | Outlook 2016

To indicate the location in formatted text where an attachment is rendered, you must insert a sequence of placeholder characters in the message's PR_RTF_COMPRESSED (PidTagRtfCompressed) property. The placeholder sequence is made up of the following characters: \objattph.

To add rendering information to formatted message text

  • When writing the stream of text to the message's PR_RTF_COMPRESSED property, insert the placeholder sequence and a space character at the position where the attachment should be rendered.

  • Set the PR_RENDERING_POSITION (PidTagRenderingPosition) property of each attachment to a numeric value. The lowest value should be assigned to the PR_RENDERING_POSITION property of the first attachment to appear in the formatted text; the highest value to the last attachment.
