Hi There,
The new Outlook doesn’t currently support auto CC rules like the classic version. Here are the options that you can try:
- Switch to Classic Outlook: Toggle off the new Outlook in Settings to access full rule functionality.
- Use Outlook Desktop: Set up an auto CC rule via File > Manage Rules & Alerts.
- Power Automate: Create a flow to auto CC sent emails if you have access to Microsoft 365 Power Automate.
For now, you can also submit feedback via Help > Feedback to request this feature in the new Outlook.
