Note Microsoft Message Queuing is also known as MSMQ. The Message Queuing service deletes all empty message files for recoverable and transactional messages upon startup.

By default, MSMQ attempts to group messages to maximize TCP packet use and reduce traffic on the network. This article discusses how to configure MSMQ to send messages immediately.

Fixes an issue in Windows 7 and in Windows Server 2008 R2 in which Message Queuing (MSMQ) may become unresponsive when you perform lots of remote reads on the MSMQ server for some time by using another computer.

When the destination for a message is tried for connection, MSMQ waits until success/failure for that connection attempt is returned. In parallel, no attempt is made for connecting other destinations piped, as messages are processed sequentially by sender from that queue.

When you install Microsoft Windows 2000 Service Pack 3 (SP3) or later on a computer that is running the Windows 2000 operating system, you may not be able to locate a private queue in the Computer Management window. If you try to create a new private queue, you may receive the following error message: Cannot create ' <Private Queue Name> '.

Fixes an issue in which you cannot send or receive messages by using Message Queuing 4.0 or Message Queuing 5.0. This issue occurs on a computer that has multiple IP addresses.

Delayed delivery when you send many messages on a Windows 7, Windows Server 2008 R2, Windows 8 or Windows Server 2012-based Message Queuing server. Consider the following scenario: You install Microsoft Message Queuing (also known as MSMQ) on a computer that is running Windows 7, Windows Server 2008 R2, Windows 8 or Windows Server 2012.

Additionally, the computer is in a failover cluster. You run a local instance of Microsoft Message Queuing (also known as MSMQ) together with one or more clustered instances of Message Queuing on the same computer.

Fixes an issue that occurs when you enable message encryption in Windows 7 or in Windows Server 2008 R2.
