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.

To view messages in a queue

  1. Follow steps 1 through 4.

  2. In the Queue Viewer, click the Messages tab. A list of all messages on the server to which you are connected is displayed. To adjust the view to a single queue, click the Queues tab, double-click the queue name, and then click the Server\Queue tab that appears.

  3. To view detailed information about a message, select a message, and then click Properties in the action pane.
