I want to hear your opinions on how does your company keep big e-mails (over 20-30mb) in order that the e-mails can be pulled out from the archive in couple of years if it comes to a legal dispute?
Our company has to keep all e-mails related to a project for 20 years. The problems are with e-mails that contain big files, .pdf-s for example that are 10-20-30mb big. We use journaling in Exchange, and every incoming/outgoing e-mail is saved then later to a .pst file monthly. I would like to teach my colleagues to use OneDrive and share the files but my CIO says that we cannot track what was sent, the contents of the files inside the e-mail. If it comes to a legal dispute we cannot prove that the file on that date in 2021 had that content, and we are talking about infrastructure projects.
