I understand that this may not be the point you are trying to make, but it's important to note that deleting data can result in fines. As mentioned by others, regulated entities such as banks are required to retain data for a certain period of time. For example, a bank regulated by the EU needs to store most data for 10 years, which includes all emails sent by the bank, except for sensitive customer core data that is no longer needed. So what happens if a bank employee accidentally deletes an email in Microsoft Exchange? This is can not happen due to the policies in place. All emails are stored in a hidden folder for as long as necessary, ensuring that no data is lost.
