Transport queues are a temporary storage location for messages that are in transit. Each mailbox server can have multiple queues at any given time, depending on the destination of the message. In this recipe, we'll cover several methods that can be used to view queued messages, remove messages from queues, and more.
To view the transport queues that are currently in use on a specific server, use the Get-Queue cmdlet:
Get-Queue -Server tlex01
In this example, the transport queues on the tlex01 server will be returned. The output might look similar to the following screenshot:
In this example, there is one message awaiting retry due to a DNS resolution problem for the destination domain.
