An employee was sending emails to her friend. Somehow Office 365 spam filter is classifiying that email conversation as outgoing spam. SCL is 5. When I set up the outgoing spam policy I configured it to BCC me a copy of the email when an outgoing message is being categorized as spam. I find that she is using vulgar language and that she is even talking about other employees, her boss and the CEO. And this is all to an external person. This in my eyes is unethical. Should I, as the head of It, report it to HR?
