ExchangeQueue Class

The ExchangeQueue WMI class has properties that return information about the dynamic queues created to transfer individual messages between mail servers. An ExchangeQueue is part of an ExchangeLink. ExchangeQueue objects are not the same as the queues listed in the Exchange System Manager.

Namespace

\\COMPUTERNAME\ROOT\cimv2\applications\exchange:ExchangeQueue

Provider

The ExchangeQueueProvider supplies instances of the ExchangeQueue class.

Origin

The ExchangeQueue class does not extend any other class.

Qualifiers

dynamic

Properties

Property	Description
LinkName Property	[key] string LinkName; The LinkName property specifies the name of the link in which this queue is contained.
ProtocolName Property	[key] string ProtocolName; The ProtocolName property specifies the transmission protocol for the queue.
QueueName Property	[key] string QueueName; The QueueName property specifies the name of the queue.
VirtualServerName Property	[key] string VirtualServerName; The value of the VirtualServerName property is the integer number of the virtual machine that is the source of the queue. This number is the Microsoft® Active Directory® common name (CN) for the virtual server object.
CanEnumAll Property	boolean CanEnumAll; The CanEnumAll property, when True, specifies that the queue can enumerate all of the messages that it has waiting for transmission. The CanEnumAll property corresponds to the thirty-first bit (0x40000000) of the MsgEnumFlagsSupported property.
CanEnumFailed Property	boolean CanEnumFailed; The CanEnumFailed property, when True, specifies that the queue can enumerate the messages that it has waiting for transmission that it was unable to transfer. The CanEnumFailed property corresponds to the ninth bit (0x00000100) of the MsgEnumFlagsSupported property.
CanEnumFirstNMessages Property	boolean CanEnumFirstNMessages; The CanEnumFirstNMessages property, when True, specifies that the queue can enumerate the first N messages that it has waiting for transmission. The CanEnumFirstNMessages property corresponds to the first bit (0x00000001) of the MsgEnumFlagsSupported property.
CanEnumFrozen Property	boolean CanEnumFrozen; The CanEnumFrozen property, when True, specifies that the queue can enumerate messages that it has waiting for transmission that have been frozen. The CanEnumFrozen property corresponds to the sixth bit (0x00000020) of the MsgEnumFlagsSupported property.
CanEnumInvertSense Property	boolean CanEnumInvertSense; The CanEnumInvertSense property, when True, specifies that the queue can enumerate messages that it has waiting for transmission that do not match the criteria requested. For example, requesting the oldest messages while inverting the request sense would return the newest messages. The CanEnumInvertSense property corresponds to the thirty-second bit (0x80000000) of the MsgEnumFlagsSupported property.
CanEnumLargerThan Property	boolean CanEnumLargerThan; The CanEnumLargerThan property, when True, specifies that the queue can enumerate the messages that it has waiting for transmission that are larger than a specified value. The CanEnumLargerThan property corresponds to the fourth bit (0x00000008) of the MsgEnumFlagsSupported property.
CanEnumNLargestMessages Property	boolean CanEnumNLargestMessages; The CanEnumNLargestMessages property, when True, specifies that the queue can enumerate the specified number of the largest messages that it has waiting for transmission. The CanEnumNLargestMessages property corresponds to the seventh bit (0x00000040) of the MsgEnumFlagsSupported property.
CanEnumNOldestMessages Property	boolean CanEnumNOldestMessages; The CanEnumNOldestMessages property, when True, specifies that the queue can enumerate the specified number of the oldest messages that it has waiting for transmission. The CanEnumNOldestMessages property corresponds to the eighth bit (0x00000080) of the MsgEnumFlagsSupported property.
CanEnumOlderThan Property	boolean CanEnumOlderThan; The CanEnumOlderThan property, when True, specifies that the queue can enumerate the messages that it has waiting for transmission that arrived before a specified date and time. The CanEnumOlderThan property corresponds to the fifth bit (0x00000010) of the MsgEnumFlagsSupported property.
CanEnumRecipient Property	boolean CanEnumRecipient; The CanEnumRecipient property, when True, specifies that the queue can enumerate the recipients of messages that it has waiting for transmission. The CanEnumRecipient property corresponds to the fourth bit (0x00000004) of the MsgEnumFlagsSupported property.
CanEnumSender Property	boolean CanEnumSender; The CanEnumSender property, when True, specifies that the queue can enumerate the senders of messages that it has waiting for transmission. The CanEnumSender property corresponds to the second bit (0x00000002) of the MsgEnumFlagsSupported property.
GlobalStop Property	boolean GlobalStop; The GlobalStop property specifies whether the queue is currently stopped.
IncreasingTime Property	uint32 IncreasingTime; The IncreasingTime property specifies the amount of time, in milliseconds, that the number of messages waiting to be transferred by the queue has been increasing.
MsgEnumFlagsSupported Property	uint32 MsgEnumFlagsSupported; The MsgEnumFlagsSupported property specifies a bit-mapped set of flags that indicate what types of objects can be enumerated. The individual bits of this property are available as the queue CanEnum properties in this class.
NumberOfMessages Property	uint32 NumberOfMessages; The NumberOfMessages property specifies the number of messages that are waiting for transmission by the queue.
SizeOfQueue Property	uint64 SizeOfQueue; The SizeOfQueue property specifies the total size of all messages in the queue, in bytes.
Version Property	uint32 Version; The Version property specifies the version number of the Microsoft Exchange software.
VirtualMachine Property	string VirtualMachine; The VirtualMachine property specifies the name of the virtual machine that is the source of the link.
