PidLidValidFlagStringProof Canonical Property

Applies to: Office 2010 | Outlook 2010 | Visual Studio

Validates whether the dispidRequest (PidLidFlagRequest) property’s value was set by an agent who knew the value of the PR_MESSAGE_DELIVERY_TIME (PidTagMessageDeliveryTime) property.

Associated properties:

dispidValidFlagStringProof

Property set:

PSETID_Common

Long ID (LID):

0x000085BF

Data type:

PT_SYSTIME

Area:

Task

Remarks

On non-sendable objects (received mail and non-mail objects), clients should set this value to the value of PR_MESSAGE_DELIVERY_TIME when modifying dispidRequest.

Since the value of PR_MESSAGE_DELIVERY_TIME cannot be predicted by the sender, if the value of this property is equal to the value of PR_MESSAGE_DELIVERY_TIME, it is reasonably certain that the value of dispidRequest did not originate from the sender of the message. A client can decide how to present the value of dispidRequest to the end user based on the result of this comparison in accordance with the specific security policy of the client. If the value of dispidRequest is ignored due to the presence of a value for dispidFlagStringEnum (PidLidFlagString), this property must be ignored.
