isDeliveryReceiptRequested	Boolean	Indicates whether a read receipt is requested for the message.
isRead	Boolean	Indicates whether the message has been read.
isReadReceiptRequested	Boolean	Indicates whether a read receipt is requested for the message.
multiValueExtendedProperties	multiValueLegacyExtendedProperty collection	The collection of multi-value extended properties defined for the message. Nullable.
