I created account for existing POP3 user on the new computer and then copied Outlook folder from old computer and paste/replaced to a new computer, because I have created folders in inbox.
One thing I know all the emails are still POP3 server and never were deleted and I think that's why my old emails are coming up and duplicated too.

thanks for your time and help

Your welcome.

With POP3 connection 96% of the time there is a setting that leaves a cop of all data, including folders, on the server. So if you decide to change computers or access the account form a different location the data is not pulled to just that location.

I'm glad i was helpful.
