(I am Facing problem about folder does not exist in Uipath even though it is exist in outlook 2013 and that is ‘Inbox Folder’ nothing but default folder)

If you still face the issue you can try.
Open the Outlook As administrator and then navigate to Trust Center Settings → Programmic access → Select last option.
Hope this works.
