HI guys.
This morning we moved all the mailboxes from exchange 2003 to 2007.  Now, some users (approximately 6 or 7 out of 40) can't connect to exchange.  It is a mixture of outlook 03 and 07 clients.

Is Outlook looking for the 2007 server? Some of the clients after our move did not change from the old server. Check the users Outlook profile to see which server it is going after.

What errors are you getting or what is happening? Is the Microsoft Exchange System Attendant service started?

Yes the System Attendant service is started.  Everything seems to be set up correctly only about 5 people can't connect.

For instance, on some users, when I try to edit their profile, it tells me that the server is unavailble and gives me the option to retry or work offline.

Have you tried deleting and creating a new profile for them?

I was trying to avoid that but it's looking like the next logical step.

If you go into the management console and go to the properties of their mailbox the server name listed there matches the one that their Outlook is trying to connect to?

Yes the correct server is listed.  One user gets a message saying "outlook is trying to retrieve data from the exchange server" if they try to send a message.  Another gets a "server unavailble" message.

No luck.  Still getting the same behavior from the affected systems.  They can ping the server, OWA works fine as well.

Try some of what this post has in it: http://groups.google.com/group/microsoft.public.exchange.clients/browse_thread/thread/83800b36ef3300d6/38b85be2ab7a7644%2338b85be2ab7a7644

Also do you enter the FQDN of the exchange server in the profile or just the server name?

Well after 7 hours on the phone with microsoft tech support it apparently was a problem with the HP NIC Teaming software.  After disabling that the outlook clients connect without issue.  Thanks for your efforts though.
