A user using Google Apps Sync with Outlook on their desktop PC has just deleted all of the messages from theit Inbox and all their messages in subfolders (ie mail marked with labels in Gmail)
That has wiped clean Gmail too, so the mailbox has nothing in it
Google Apps support say that they maintain no further copy and that deletion can't be undone.
I don't have the machine in my possession yet, but will get it. Any ideas what might be possible? I presume Google Apps Sync created a PST file which held the data, while it's not in Trash or Deleted Items I doubt that the data file has shrunk to zero - so perhaps there's some way of extracting individual messages from a PST?
I have enabled a trial of Google Vault on GA support's advice, apparently it might index the deleted but not yet quite erased data.
