Hi Luke,

You don't mention the version of BE you're using. If you're using any version of BE 2010 other than R3 I'd suggest you start by upgrading to R3 with all available patches, and push-installing these to your remote servers.

If you're running anything else, make sure your media server is up-to-date and that the remote servers have had these patches push-installed to them.

If it's only one mailbox, I would suggest to export the mailbox to PST, delete the mailbox, run mailboxmanagement, recreate mailbox en import the PST to the mailbox.

If this response answers your concern, please mark it as a "solution"

As well as Zero Cool's answer (which I was more or less about to say as well) then look at whether you have used odd characters in any of the details of the mailbox that you have not used in other mailboxes.

For instance we have seen issues with customers using the [ and ] characters in the the text based user name (what is seen in Outlook instead of the login name) in the past.

Also has the mailbox been renamed in the past which might cause a mismatch of metadata that might only be visible when looking at the hidden AD properties of the user.
