I can't quite figure out what this would be useful for, but ok.
Google will enable Confidential Mode for our G-Suite domain on Tuesday, June 25. This means that users will be able to protect sensitive information from unauthorized access since recipients of messages in confidential mode do not have the option to forward, copy, print or download messages which also might include attachments. Users can set expiration dates for messages, revoke message access at any time and require an SMS verification code to access messages.
Note that this mode helps prevent recipients from accidentally sharing an email but does not prevent users from taking screenshots or photos of your messages/attachments.
More detailed information can be found on the ITS page short link to http://bit.ly/confidentialB
Any questions can be directed to the Help Desk.
