2.3.3.1 Impact of Message Changes on the MIME Skeleton

When a stored message is modified via remote operations (ROPs), as specified in [MS-OXCROPS], the value of the PidTagMimeSkeleton property ([MS-OXCMSG] section 2.2.1.28) is deleted or left unchanged, depending on the changes made to the message:

  1. Changes made to the following Message object properties SHOULD leave the PidTagMimeSkeleton property unchanged:

  2. Changes made to the following Message object properties leave the value of the PidTagMimeSkeleton property unchanged. However, MIME writers SHOULD prefer the values of these properties over data from the MIME skeleton when generating MIME messages.

    • Follow-up flags: These are stored in the PidLidFlagRequest property ([MS-OXOFLAG] section 2.2.1.9), which maps to the X-Message-Flag header in a MIME message. If this header already exists in the PidTagMimeSkeleton property, its value SHOULD be updated when generating a message. If the X-Message-Flag header is updated, it SHOULD be added to the top-level headers of a generated MIME message as well as to the PidTagMimeSkeleton property.

    • PidTagImportance ([MS-OXCMSG] section 2.2.1.11): The importance property maps directly to the Importance header. If the client allows the value of this property on a message to be modified, then the Importance header SHOULD be included in a generated MIME message and the change included in the stored PidTagMimeSkeleton property.

  3. Changes to any other Message object properties that affect the MIME structure or content of a message SHOULD result in deletion of the PidTagMimeSkeleton property associated with the message. The following list specifies the other Message object properties that fall into this category.
