I have a mailbox that is showing up on mail server that I added 6 months ago.  It has been working fine but recently when sending emails to this email box I am getting 5.1.1 error (Mailbox not found)  it is random and only the one mail box.
Are there any tools that I can run against the mail box to recover or rebuild or fix?
Currently running Exchange server 2010 Ver  14.01.0438.000.
When I try to setup the mailbox on a new client the client tell me mailbox not found?

This tell me that the mailbox has a problem or?

Please Advise.....

It's possible that the account had the mailbox disconnected from it. Check the disconnected mailboxes list in the Exchange Management Console to see if it is in there. Also see if you can access the mailbox in OWA by clicking the button on the top right of the OWA window and selecting Open another mailbox.

No the email box is still configured in the Mail server as active.
I am trying to compact the mailbox and it is trying but going no where fast, I run the analyzer and I get a generic message that I have a bad email box, but it does not identify which one or why?

This could be caused by a corrupted message or messages in the mailbox.  What you might need to do is to export the mailbox contents, delete the mailbox, then create a new mailbox for the user and then reimport the contents.  During the export process you can specify how many corrupted messages should be skipped.  Here's a link to the start of a series of short step-by-step instructions on using the EMS to import and export mailboxes:

Try running this command first to give your logged-in user ID the rights to run the command:

New-ManagementRoleAssignment –Role “Mailbox Import Export” –User "DOMAIN\USER"

BTW - I think you have to close and re-open the EMS after adding the role assignment.

If you are using a remote admin connection you should be able to run it.  Or you can install the Exchange management tools (console and shell) on your workstation if it's at least Windows Vista or above and 64-bit.
