In the same way Microsoft Outlook will pop up an alert if you try to send an email with the To field left blank, or try to send a calendar invite with the Location field blank, I want an alert that comes up if I have left the Bcc field blank. Any ideas on how this can be achieved?
This could be done with an Outlook add-on. You might even be able to do a VBA script that checks for it. – Ramhound – 2013-07-18T16:54:50.770
