I am not holding out to much hope on this, but as a long shot, a user (XP workstation, outlook 2003 software) had been granted (wrongly) delegate rights to a team mailbox, this user has viewed an email they shouldnt of (which became apparent during general office discussion), the user is claiming they didnt view that mailbox and that email, when the evidence suggests different. Is there any possible way to prove on their machine that they may of opened that email from their PC? Or is it impossible (I highly suspect they'll be no purpose set audit logs on that mailbox, but I wondered if on the PC itself there could be). We can prove they did have access to the mailbox via delegate rights using PFDavAdmin. At a bit of a loss as to where to ask forensics to start looking, or whether to invest time/money in doing so.
