You should apply it only to systems that have had the Exchange Server Analyzer Tool run against them and are experiencing that specific issue. The Exchange Server Analyzer Tool, available as a free download, remotely collects configuration data from each server in the topology and automatically analyzes the data. The resulting report details important configuration issues, potential problems, and nondefault product settings. By following these recommendations, you can achieve better performance, scalability, reliability, and uptime.

Microsoft® Exchange Server 2007 setup displays this warning because its attempt to uninstall a transport role could cause data loss from a transport queue.

Exchange 2007 setup checks to make sure that the transport queues are empty before it removes the roles associated with managing those queues.

If you remove the transport roles before delivery of messages still in the transport queues, those messages may be held indefinitely.

To resolve this issue, inspect the referenced queues to make sure that they are empty of messages before you continue with setup.

To view the contents of a queue

  1. Open the Exchange Management Console.

  2. In the console tree, click Toolbox.

  3. In the result pane, click Exchange Queue Viewer.

  4. In the action pane, click Open Tool.

  5. In the Queue Viewer, click the Queues tab. A list of all queues on the server to which you are connected is displayed.

  6. Right-click the queue you want and select Properties to view the properties of the queue.
