When recalling a vaulted message, the wrong email is displayed

Environment:

Enterprise Vault for Exchange v_10.0.4 running on a stand-alone Windows 2008 R2 server.

We had a user that, when recalling an email, a different email than expected is loaded. I have no corrupt or offline indexes. All indexes are healthy and online. I haven't yet tried to rebuild her index yet. I wante to first check with the community and see if anyone has seen this before.

Thanks in advance.
