Exchange 2003 to 2010 migration - legacy mailbox

I had two users that were showing up as legacy mailboxes and I couldn't seem to change them. I did some reading and one of the notes on a web site said to disable the accounts, shut down EMC and reopen it and they should be regenerated.
That didn't happen.
Now I've got two accounts in limbo that I don't know how to get back.
This issue arose when I was trying to un-install Exchange 2003 from SBS
The two accounts show up in Exchange 2003 System Manager but I can't connect to the exchange
Now I see that one of the mailboxes doesn't even show up on the 2003 box

Need some help fast
thanks

Ok, went through that but both the users mailboxes don't exist
Only one of the users on the 2003 box still shows a mailbox
there must be a way to re-enable them?

if you have uninstalled exchange 2003 then you cant moun the data base and open mailboxes. only option is to restore the old server in disaster recovery mode, open the mailboxes and copy or export the contents to a PST, then re-create the users in 2010 and upload their content

No, I haven't removed exhange 2003 yet because of the problem that I am having. there are a number of other users listed in the exchange 2003 mailbox but with zero items. then there is the one account sitting there that I am having an issue with.
like I said, after I disabled the accounts, that is when the "stuff" hit the fan

I have two issues.
1. two accounts that were showing up as legacy accounts under Ex 2010. Open up Ex 2003 and both of the accounts show up there with a file size (one was 1.2GB and the other was 1.7GB)
These are the two accounts that I disabled in Ex 2010. That's when I lost them and can't get them back.

2. before I can remove exchange, their cannot be any users listed in the account folders and of course, the two accounts that I've listed above are sitting there along with a number of other accounts that were moved over. Those other accounts show a zero size.

I've migrated about 4 other systems over (exchange 2003 to 2010) and have not encountered this problem.
