How to Stop or Restart the Transfer of All Messages in a Queue

  • Article

 

When you freeze (stop) an entire queue, all messages that are currently in the queue will not be delivered. Frozen queues can continue to accept messages, but the messages will not be delivered until the queue is unfrozen (restarted). The messages inside a frozen queue will not be in a frozen state themselves.

Procedure

To stop or restart the transfer of all messages in a queue

  1. In Exchange System Manager, navigate to Queue Viewer by doing one of the following:

    • If you do not have routing or administrative groups defined, expand Servers, expand the server you want, and then click Queues.

    • If you do not have routing groups defined, expand Administrative Groups, expand Administrative Group Name, expand Servers, expand the server you want, and then click Queues.

  2. Click to select the queue that you want to stop or restart.

    Note

    X.400 queues cannot be frozen.

  3. Right-click the queue, and then point to one of the following options:

    • Freeze Messages   Messages will be trapped inside the queue. No delivery will occur until the messages are unfrozen. For example, if one or more large messages have temporarily blocked the queue, you can freeze the large messages to allow Exchange to transfer the other messages. Then, with more resources available, Exchange will be able to send the larger messages.

    • Unfreeze Messages   Remove the temporary hold on the transfer of messages.
