Creating New Mailbox for existing user in corrupt database

I have an Exchange 2010 mailbox that resides in a corrupt database. I've tried multiple methods to repair said database and because of the corruption, can't move the mailbox either. I'd like to disconnect the current mailbox from the user, create a new mailbox (for this existing user) in a different (non-corrupt) database. How do I go about doing this, keeping the users same email address, without messing up the AD account?

As for current mailbox content, It will be exported and then imported into new mailbox.

If you can't move the mailbox to another db then;

Backup the emails.
Then from EMC select mailbox and click on disconnect. This will not remove the ad object. Then purge the disconnected mailbox. Once purged you can create a mailbox for the user. Once created you can export the mail back.

You would face an issue from other users when they send email to this specific  user if they use address cache. You may have to remove the cache from their outlook.

That's what I thought (and found online) as the solution, but when right clicking on the users mailbox in EMC, "disconnect" isn't an option. Am I in the wrong place? Nor is it an option in the right pane of the EMC...?

Right click on the mailbox and it will show the option disconnect.
