Restored mailbox database, can't see the mailboxes

We had a database get dismounted and deleted accidentally, as a result, user lost access to their mailboxes.
Fortunately I had a backup of just the .edb, .chk and .log files, which I was able to use eseutil against to repair and arrived at a clean shutdown state for the .edb file.
So what I did was, I went back into Exchange Console, created a new database under the same name "DB1" as the one that was deleted before it, and specified the folder to use. Left it dismounted. I've also got the "this database can be overwritten by a restore" checked.
I then copied over the restored .edb and .chk files to the folder the new database using the same name was under, and then I mounted the new database DB2 and it said it mounted successfully.
The .edb file is 127GB, and I know there are mailboxes on it, however, I cannot see any mailboxes in the "Recipient Configuration > Mailbox" when I drill down to this new database.
How do I get these mailboxes to show back up?
I can browse the .edb with a third party tool, so how can I get the same mailboxes to "show up" inside the Exchange Management Console?
I see nothing under "Disconnected mailbox" either.
