Not applicable.

Property Value

The maximum size, in kilobytes, of the queue. The Message Queuing default specifies that no limit exists.

Exception typeCondition

ArgumentException

The maximum queue size contains a negative value.

MessageQueueException

An error occurred when accessing a Message Queuing method.

The MaximumQueueSize provides access to the Message Queuing message storage limit, which is separate from the computer's message quota that the administrator defines. For more information about the message quota, see MaximumJournalSize.

Setting this property modifies the Message Queuing queue. Therefore, any other MessageQueue instances are affected by the change

If an attempt is made to exceed either the maximum queue size or the computer message quota, messages might be lost. When the queue quota is reached, Message Queuing notifies the administration queue of the sending application to indicate that the queue is full, by returning a negative acknowledgment message. Message Queuing continues to send negative acknowledgments until the total size of the messages in the queue drops below the limit.
