In my primary AD site, I have 4 Exchange 2007 Hub Transport servers. One of them needs to go offline for a couple of hours whilst it's moved to another part of the computer room.
Unfortunately, we are a 24/7 operation.
When I power down the Hub Transport, I need to ensure that are no messages in the queue.
Does anyone know the best process for this? If I randomly check the queues of our Hubs they sometimes do have messages in the queue, not a lot, but a couple, then drop to zero, then up again, really depends on how busy we are.
Is there any way to stop mails coming into the HT but let it process the ones in there? I was thinking of perhaps Pausing the Transport service, but I guess this will prevent it processing and sending messages in the queue too.
Or, when a HT server is rebooted/ shut down, does it flush the queues anyway?
