The value of the PidTagVoiceMessageDuration property is a positive valued PtypInteger32 ([MS-OXCDATA] section 2.11.1) and is formatted as a decimal string in the header without sign or separator characters.

To generate an X-FaxNumberOfPages header, clients SHOULD set the value of the PidTagFaxNumberOfPages property ([MS-OXPROPS] section 2.695). They MAY instead use the PidNameXFaxNumberOfPages property ([MS-OXPROPS] section 2.484). MIME writers SHOULD<30> map either property to the X-FaxNumberOfPages header, preferring the PidTagFaxNumberOfPages property. The value of the PidTagFaxNumberOfPages property is a positive valued PtypInteger32 and is formatted as a decimal string in the header without sign or separator characters.

To generate an X-AttachmentOrder header, clients SHOULD set the value of the PidTagVoiceMessageAttachmentOrder property ([MS-OXPROPS] section 2.1059). They MAY instead use the PidNameXVoiceMessageAttachmentOrder property ([MS-OXPROPS] section 2.502). MIME writers SHOULD<31> copy either property to the X-AttachmentOrder header, preferring the PidTagVoiceMessageAttachmentOrder property.

To generate an X-CallID header, clients SHOULD set the value of the PidTagCallId property ([MS-OXPROPS] section 2.628). They MAY instead use the PidNameXCallId property ([MS-OXPROPS] section 2.483).
