I have a customer who wants to keep his employees's deleted emails for 5 years.. I have created a customer retention tag and policy for 1825 days and applied it on couple of users. however, after testing deleting couple of emails from the inbox and deleted folder. I can no longer recover these emails.
I wonder how does the Retention policy works? And how to access the deleted e-mails?
My customer uses only Outlook 2007.
