Retention policy and hard delete

Hey Kamran,
It sounds to me like you are trying to do what Litigation hold does through a retention policy, and they are not the same thing.
If you want to prevent users from deleting any email, you need to have E3 or higher licensing, and put those users (or all users) under litigation hold. A retention policy will just keep the mail from being removed by other means (such as an MRM) but wont protection you completely in the same way a Legal/Lit hold would.
