It does not seem possible to edit Portfolio's metadata it gathers when converting outlook PST files. The From, To, CC, and BCC fields may contain confidential email addresses under Texas law, and there does not appear to be a way to remove/edit/redact that metadata. Currently, we must extract the PDFs from Portfolio and then re-combine them. However, when doing so, we lose the order of the emails unless more manual labor is used, since the date of each email is also lost. Being able to remove/edit/redact confidential email addresses would make a huge positive impact on governmental entities being able to appropriately comply with our public information laws.
