We use O365 in one tennant for a foundation of schools. In the GAL are staff and students, with the latter being identified as "(Student)" in their display name as well as having a warning in the Tool Tip. Both staff and students are on the same domain name.
Is there a way (in Security & Compliance Policy?) to flash up a warning to staff who are sending emails to students? We have a few repeat offenders who do not check their work before submitting (so to speak) and end up emailing students confidential information.
E-Mail is usually sent by Outlook client, however may also be online via a browser. Small percentage via the Outlook App.
Security & Compliance Conditions look almost there, but under Rules ideally we would want "Sent to" and then pick the "All-Students" distribution list. However this is not an option.
