2.2.3.2.13 Message Expiry Time

To set the value of the PidTagExpiryTime property ([MS-OXOMSG] section 2.2.3.7), clients MUST write the value to the Expires header.

MIME readers copy the value of the Expires header to the value of the PidTagExpiryTime property, after converting it to UTC time.

Clients MAY use an Expiry-Date header instead of an Expires header. Servers SHOULD use the value of the Expires header in preference to the Expiry-Date header, if both headers are present. A client MAY<115> use whichever header shows up last in the list of header information, either the Expires header or the Expiry-Date header, as the header used to set the PidTagExpiryTime property. However, this is not recommended.
