Outlook will not send internal emails but will send and receive external emails and receives internal mail.

I have a domain with two exchange servers. One on 2000 and one on 2003. I an wanting to move all the mailboxes from the 2000 to 2003 Exchange. I have moved one mailbox to the 2003 exchange server. When opening the outlook client for the first time it said it needed restarting as the mailbox had moved, fine, but now that account will only send externally.

Mail sent to any mailbox on the 2000 Exchange server appear to just get lost. It appears in the queue and then looks to get sent to the 2000 exchange server but then is not received by the recipient if it is any of the 2000 mailboxes.

Any ideas?

Thanks,
Andrew.

Exchange doesn't loose messages. So they are going somewhere, or a third party application is removing them.
Message tracking isn't enabled by default, you need to turn it on if you haven't.

What does message tracking say?
Any restrictions on the original server?
Antivirus or antispam quarantining the messages?
Are the messages stuck in the queues?

I'm not sure where to look for message tracking.
There are, as far as I know, no restrictions on either server.
There is no antispam quarantining the messages, the only antivirus is Sophos.
The messages are not getting stuck in the queues, they go into one, get passed to the other and then just disappear?

Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

Great, thanks for that. I can now see that the message is actually "leaving the building" to a smarthost externally instead of being routed to the other exchange server for delivery internally.
Not sure what to do about this though?

There is more to see in the tracking which may make sense to you!
The last four lines say:
10:33 Message categorized and queued for routing
10:33 message routed and queued for remote delivery
10:37 started outbound transfer of message
10:42 Message transferred to xxxxxx through SMTP

I think the 4 minute and 5 minute delays must mean that its getting timed out somewhere???

You have a smart host set on the SMTP virtual server. It needs to be removed.
ESM, Servers, <your server>, Protocols, SMTP. Right click on the SMTP VS and choose Properties. Click on the tab Delivery and then Advanced. Remove the Smart Host listed.

If you need to use a smart host to get email delivered correctly then you need to use an SMTP Connector.

Thanks again.
