While you can create a rule to automatically CC someone when sending a message, you can't use a rule to automatically BCC someone (including yourself). You can use VBA to do this.
If you prefer to use an add-in, try AutoBcc or Always Bcc.
Copy and paste the code from this page into your ThisOutlookSession
project. To do this, click within the code, Select All using Ctrl+A, Ctrl+C to copy.
In Outlook, press Alt+F11 to
open the VBA editor and expand Microsoft Outlook Objects then double click on
ThisOutlookSession to open it in the editing pane and Ctrl+P to paste the code.
Don't forget to replace
someone@domain.com with the correct address.
