Queues on Hub Transport/ Exchange connectors
HiI was hoping someone could help with a query I had.Let's say I am using Exchange 2003. I have two routing groups, each with their own dedicated routing group connector servers - Connector1 and Connector2.For some reason, there is a WAN issue and messages start queueing on Connector1. Where are these messages actually being saved? In RAM, or on the physical disk somewhere - if so where?And if I was to lose this server, are they recoverable?Likewise, same question but this time if the servers were Exchange 2007 and Hub Transport boxes.

If they are, then the messages remain in theInformation Store. IIRC, if they're acting only as messagingbridgeheads and have no local databases then the messages are in thequeue folder.>And if I was to lose this server, are they recoverable?That depends on what you mean by "lose". If it explodes, then youprobably won't get much unless you're making very frequent backups ofthe mailroot directory and the databases.>Likewise, same question but this time if the servers were Exchange 2007 and Hub Transport boxes. Exchange 2007 makes things a bit easier. The messages are always keptin mail.que database, and that can be moved to another HT server -- ifthe disk isn't part of your definition of "lose".---Rich MatheisenMCSE+I, Exchange MVP--- Rich Matheisen MCSE+I, Exchange MVP

Hi,For Exchange 2003, the queues are stored in memory. And in Exchange 2007, the queue is placed in mail.que database.As Rich said, if the message is come from the local mailbox server which stuck in the Connector, the message is still stayed in the store. It cannot be recovered from the queue but need to resend by the sender.If the message is come from the other routing group's mailbox server, the message is stayed in the Queue folder which placed on the hard disk. To recover them, you can move the message from the Queue Folder to the Pickup folder will force Exchange to re-process the message.ThanksAllen

Bcc recipients won't get the e-mail, either.All that nice routing information stored in the data fork of the NTLMfile is ignored.---Rich MatheisenMCSE+I, Exchange MVP--- Rich Matheisen MCSE+I, Exchange MVP

Hi Rich,Thanks for your clarifying. Indeed, that should be the problem. Allen
