Using New Outlook on Windows for professional communication and productivity
Hello Bridge
Thank you for your question.
The Notes module is currently partially available in New Outlook. While New Outlook supports basic note functionality for notes stored in the primary mailbox, notes stored in the Online Archive are not supported and cannot be viewed there.
Microsoft’s official feature matrix
If you need to access archived notes, please open Classic Outlook, where notes in the Online Archive can still be viewed. If needed, you can move the notes back to the primary mailbox, after which they will be accessible in New Outlook.
I recommend submitting feedback and upvoting existing requests through the Outlook Feedback Portal.
The product team regularly reviews customer feedback, and many features and improvements are prioritized based on user input.
Please let me know if the information above is helpful
Warm Regards
