Type: PtypString ([MS-OXCDATA]
The PidLidTaskAssigner property ([MS-OXPROPS]
specifies the name of the user that last assigned the task. If the task has not
been assigned, this property is left unset.
Because this property is set by the client after the task assignee receives a task request, the property
will not be set on the task
assigner's copy of the Task
When the client adds or removes a task assigner from the
stack of task assigners listed in the PidLidTaskAssigners property
this property is set to the added or removed task assigner.
