Students sometimes accidentally share school documents or data externally using the Email as attachment feature in Docs editors. Schools don't want that. It's a security issue.
Safe Doc can disable the Email as attachment feature for your students. If you have yet to install Safe Doc, apply a 30 days trial.
What's changing?
In Google Docs editors (Docs, Sheets, Slides and Drawing), the Email as attachment feature can be found in File > Email > Email this file. The Documents or spreadsheets is converted to PDF (or Microsoft office files etc.) before actually sending out.

Safe Doc disables this feature so that File > Email as attachment is no longer accessible.

How to get started?
Given that you have deployed Safe Doc and read Safe Doc Configuration, it's simple to add or set the following policy to your policy configuration.
{ "BlockEmailAsAttachment": { "Value": true } }
