Freeze and Unfreeze an Entire Queue

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

To stop (freeze) or re-start (unfreeze) the transfer of all messages in a queue:

  1. Start System Manager
    On the Start menu, point to Programs, point to Microsoft Exchange, and then click System Manager.
  2. Navigate to the desired queue.

Option Description
Freeze Messages Messages will be trapped inside the queue. No delivery will take place 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.
