Hi @Anderson,Jeffrey ,
Welcome to our forum!
As I know, the "On My Computer" folder is not supported now in New Outlook. To continue use the "On my computer" folder, I'm afraid that you need to switch to Legacy Outlook. For more information about the feature of New Outlook for mac, please refer to: New Outlook for Mac features.
