This does not make sense within the architecture of Microsoft Outlook. The emails are not stored in separate files. You need to use a MS Outlook utility to reclaim freespace, and there is no wiping.

Quite possibly she copied the files she wanted to copy and release, and then used bleachbit on the outlook file.

Yes. Five simple steps:

1. Delete all the emails she doesn't want seen.
2. Export the remaining emails to a new machine with a clean Windows / Outlook install.
3. Sanitize the old drive using BleachBit or whatever.
4. Remove and shred the old drive (just to make sure).
5. Put a new drive with a fresh Windows install in the old machine (or just ash-can it).
