Strictly Confidential in email
The Strictly Confidential label assigns permissions now: all employees get Co-Owner permissions. Emails inherit the label from attachments. An employee labels an email, a colleague reads and replies in Outlook, an attachment labels the email, DLP stops the label and a linked file going to a partner, and a partner who gets the file anyway cannot sign in to open it.

can open it. We look at the label settings, then follow
Eli in Outlook: a colleague, an attachment, a link, and
a partner who gets the file anyway.
