Situation: You want to always be able to access emails that you sent in the past, and you want to ensure that you will have access to these emails even after 16 months (USC's retention period for emails). Since you cannot create a rule to target outgoing emails, as a workaround you BCC yourself on any emails you send. Then, you create a rule with these settings:
- Condition: You are the email sender
- Action: Move the email to another folder (make sure the folder meets the requirements discussed in "Retaining emails")
