Variant type: VT_I2
Description: Priority level of the queue. PROPID_Q_BASEPRIORITY applies only to public queues that can be located through the directory service (using a public format name). The base priority of private queues, as well as public queues accessed directly, is always 0x0000. Any attempt to create this property and set its value or to set the value of an existing property for a private queue when the queue is being created or after the queue is created will be ignored and will cause no change. The value MUST be set to a valid priority level. Priority levels are integer values between -32768 (0x8000) and +32767 (0x7fff). The default priority level is 0x0000.
