Hi @ケシ
Welcome to our forum!
Currently, the Notes folder cannot be moved to other subfolders. According to my research, you can move ‘Notes’ in Outlook to either folders created under ‘Notes’ section of the same data file or to the different data file ‘Notes’ section.
Please kindly understand that many functions are not designed at present. At present, what I can do for you is to submit feedback for your request and I have post here, and you could vote for it. If you have any suggestions or ideas, it's suggested that you could post here. Hope Microsoft will notice this in the future. Thank you for your understanding and support!
