Using Classic Outlook on Windows for personal email, calendar, and contact management
Dear Antti,
Good day! Thank you for posting to Microsoft Community. We are happy to assist you.
Based on your description, you want to know how to automatically add yourself as CC or BCC into the emails you send - alternatively, automatically add a copy of all sent emails (by you) to your inbox.
Based on your requirement we have checked from our side with New Outlook for Windows, and seems this feature is not available in new Outlook for windows. Please comprehend that as New Outlook for Windows is still under development stage, so many feature will be added based on users feedback, so would you please submit your valuable feedback by open New Outlook for Windows > Help > Support. For more information please refer to: Contact support and provide feedback within the new Outlook for Windows - Microsoft Support.
At the same time, you may try the work around to revert back to classic Outlook, you may switch the toggle off in the new Outlook and it will automatically open the classic version.
And, if you are Microsoft365 business user, you can also create mail flow rule from Admin center (To set up transport rules, admin permission is needed, if you are not the admin, please contact the admin to set the rule for you.)
For more detailed information about mail flow rules, please refer to: Manage mail flow rules in Exchange Online | Microsoft Learn.
I hope the information above can be useful for you. If there is any update or I misunderstand you, please feel free to let me know. I will continue to assist you. Your understanding and co-operation are highly appreciated.
Thanks for your precious time. Have a nice day!
Sincerely,
