Restricting Permissions on Sent Mail in Outlook
In Outlook, you may restrict the permissions that recipients of their emails have. This service is called Information Rights Management (IRM).
IRM is a way for users to protect sensitive information contained within emails. Usage rights are given to the email using Active Directory Rights Managements Services (AD RMS) and allow users to control rights, actions, and permissions (e.g., who can view, forward, or print the message).
Applying IRM in Outlook
Open a new email in Outlook. IRM can be applied by going to Options and then Encrypt.
Choose one of the four permission policies listed.
Encrypt-only: Encrypts the email, including attachments, while in transit and at rest in the recipient’s mailbox. The entire email thread will remain encrypted.
Do Not Forward:Â Allows recipients of these emails to reply, edit, and save the email but not forward to internal or external users. The forward button on the email will be grayed out.
University of Connecticut – Confidential: Indicates the message is intended for users inside the organization only. The recipients will have full permission to the email.
University of Connecticut – Confidential View Only: Indicates the message is intended for users inside the organization only, and the message can only be viewed. The recipients cannot save, edit, reply, or forward the email.
