Recreate AD account while retaining mailbox

One of our developers is having this issue. We have narrowed it down to being a problem with his domain account.

As we need to get this developer working again asap my solution would be to recreate his AD account. The method I am contemplating is to disable his mailbox (Exchange 2010) thus disconnecting it from his AD account. Deleting his AD account, recreate the AD account and then reconnect the mailbox.

I have not had to do this before and was looking for a confirmation this should work and the method I should use.

I have a test account I have setup that I can try this with first.

Any help appreciated.

I delete the user - his mailbox will then appear under 'disconnected mailbox's'. Then I recreate the user > Go to the disconnected mailbox and 're-connect' it to the newly created user.

Also if your 'super worried' you can always back up his mailbox with Outlook (export to PST) first!

Just to update and close this issue I did the following ;

- Deleted the AD account.
- Ran get-mailboxdatabase | clean-mailboxdatabase from the Exchange Management shell. (makes the disconnected mailbox appear in the disconnected mailbox section).
- Recreated the AD account.
- Ran AD replication from within the AD sites and services tool.
