Messages that you try to send over HTTPS may remain in the outgoing message queue in Message Queuing 3.0

When you try to send messages over HTTPS in Microsoft Message Queuing 3.0, the messages may remain in the outgoing message queue.

Note This problem only occurs on computers that are running Microsoft Windows Server 2003. It does not occur on computers that are running Microsoft Windows XP.

This problem may occur if Message Queuing 3.0 cannot reach the location of the certificate revocation list (CRL) that is specified in the properties of the certificate. Typically, this behavior occurs when the site cannot be accessed or when the port that is specified in the certificate is not open.

4.	Type SkipRevocationCheck, and then press ENTER.
