Question
How do I trigger CRES encryption in Microsoft Outlook using the confidential flag?
Encryption is typically triggered via a specific keyword in the subject line of an email by using an Outgoing content filter. We use the same procedure here but trigger on a header instead of the message subject.
- An outgoing content filter should be created with the condition of "Other header".
- Fill in "Header Name" box with "Sensitivity" (do not put quote marks in) and then select "Header Value" radio button with a Value of "Company-Confidential" (do not put quote marks in).
- Select the appropriate action (i.e. Encrypt and Deliver Now) and add the content filter to the appropriate mail policies.
- Apply the outgoing content filter to your default outbound mail policy and any other mail policies you may have.
- Submit and Commit Changes
- Validate your configuration is correct by sending a test email with the Confidential Flag checked.
Note: Additional sensitivities are available such as "private" and "personal". You would replace "private" with "Company-Confidential" in the above example if you wish to use the private sensitivity flag.
