The property gets or sets an instance of the DateTime structure that represents the date on which a task was completed.
Assembly: EWS (in EWS.dll)
Setting the property has the same effect as setting the PercentComplete property to 100 or the Status property to Completed. In a request that sets at least two of these properties, the last processed property will determine the value that is set for these elements. For example, if the PercentComplete property is 100, the property is January 1, 2007, and the Status property is NotStarted, and the properties are streamed in that order, the effect will be to set the Status property of the task to NotStarted, the property to a null reference (Nothing in Visual Basic), and the PercentComplete property to 0.
