The application did not set theproperty before reading it.
A queue's modification flag is set when you change the properties of a queue, but not when a message is read or written to the queue.
The MessageQueueCriteria properties are combined using a logical AND, so setting both and ModifiedBefore bounds a time interval for the queues' last modification. If you set only , there is no upper boundary on the date.
