Exchange 2007 won't send email

Hello,
We have our exchange 2007 server currently on Virtual Iron, and are migrating it to Xenserver.  I attempted to do this over the weekend with platespin and it seemed to work fine except I could no longer send email.  All serices started, I could recieve email and log in with outlook and owa.  However when I sent email from either outlook or owa it sat in the outbox and wouldn't send internal or external. however, programs like IPmonitor were able to send using the SMTP protocal.  Does anyone know why this would be? Does anyone have any suggestions on how to try this again next week and have it be sucessful using platespin?  I did not stop any services or anything this attempt, and used a block based vss transfer.  Thank you for any help you can provide.

I did the conversion again this weekend and the same thing happened.  It seems that during the conversion it lost the configuration domain controller.  Once I reset that and restarted the services it was sending fine again.

Ensure that all services are up, including Microsoft Exchange Transport Service, and Information store.

Check the Exchange Management Console --> Toolbox --> Queue and see if the mails are in the queue.

any errors in the event logs?

All services were running and I had full access to all email.  I don't know if they were in the queue.  I reverted back to the old machine once the problems started.

Was the exchange store mounted?

I would check queue / stores are mounted and let us know on the next test what the results are.

I know the stores were all mounted.  And the queue had some email in it from prior to the conversion but I pretty positve it did not have anything new in it.  I belive I cleared all the emails from the queue and didn't see anything new arrive in it while testing.

So if nothing arrived in the queues it might indicate an issue with the Outlook client 'seeing' the exchage server after the move. You say that OWA behaves the same way? What URL do you use for OWA, the new URL?

I'm not very familiar with your virtualisation technologies, so I'm trying to figure out if the clients may have been looking for the old server reference, and not the new server?

when migrated using platespin everything came online with the same IP addresses and everything after it shutsdown the source server.  It is basically a mirror of the old system.

Does outlook show as connected? Is it running in cached or online mode?

I assume outlook clients are connecting using MAPI?

A few other things to check there, you might also enable message tracking on the server to see if any mail is making it to the exchange server.

Event logs for issues too...

outlook shows connected, I do not run cached mode.  receiving emails is fine. Just no sending.

If outlook shows 'connected' rather than 'online' then you are using cached mode.

So mail sent from external users gets through to the new server and you can see this in Outlook, but you cannot send internally or externally right?

This is correct.  And I get the same result in OWA as well.

Event logs?

If you cannot send and the mail is not getting to the queue, I'd say there is a fundamental issue there, not a misconfiguration. It's a very strange problem to have MAPI clients that suggest connected, can receive mail but when sending, it does not enter the queue.

There must be something pretty dire there, I can't think of anything configuration wise that would cause that.

Event logs may give info.

Nothing in the event log.  First place I looked.  I am going to retry this coming weekend with the services and everything shut down instead of trying it live.
