mailbox move 5.0-5.5 requires authentication

I am having a problem moving mailboxes from a Windows Server 2000/ Exchange 5.0 to Windows Server 2003/Exhange 5.5

After mailboxes are moved, users are required to authenticate in order to open outlook. All logons fail.

As a test, I have created new users on the Server 2003---Exch 5.5 box and accounts work fine. My problem occurs only when I move existing mailboxes from the old server to the new.

Any help you can provide will be greatly appreciated.

Exchange 5.5 isn't supported on Windows 2003. Are you sure about those version numbers?
If you are, then compatibility is your problem. The latest version of Windows that you can install Exchange 5.5 on is Windows 2000.

Thank you for the reply. The versions are Version 6.0 (exchange 2000) on the Windows 2000 server, and Version 6.5 (exchange 2003) on the 2003 Server.
When mailboxes are moved from the version 6.0 to 6.5, users are required to authenticate whhile opening outlook. All logon attempts fail.

Your original question stated 5.0 - 5.5. After Exchange 5.5, no one (even MS) uses the version codes (6.0 and 6.5) it is all Exchange 2000 and Exchange 2003. You will get better responses if you use the accepted terminology.

The behaviour you are seeing is not correct. Are the users in the same domain as the Exchange server? Are their user accounts in the same domain? Anything odd about this migration?

Yes, the users are all on the same domain. If a mailbox is moved from the exchange 2000 server to the exchange 2003 server, users are required to authenticate. This is a very small network and only one domain is involved.
New user accounts created on the domain can use the 2003 exchange server without issue. Problems only occur when mailboxes are moved from exchange 2000 to 2003.
I apologize for using the incorrect terminology. I was surprised to find they only list the exchange details as a version number. If there is a better place to identify the exchange version, please let me know.

I would be looking at the permissions between a fresh account and on older account. I would suspect there will be a difference. If the user account and machine is on the domain then authentication should not be required.

Do ensure that the problem isn't resolved by recreating the Outlook profile.
