Not Receiving Emails, and...

[StretchNM]

Hello,
I'm new here but I hope you can help. I have an old MS XP computer with Office 2007 installed, and I built a new computer and loaded Windows 8.1 with MS Office (I think MS Office version 2013).

I have two situations:

1) I set up my email on the new computer. Now, I receive some messages on the new computer and some on the old one. There doesn;t seem to be a rhyme or reason as to which ones. They do not duplicate, though, meaning the same messages will not be received by both emails. I should add that email address has not changed.

2) I have several personal folders in my old Outlook that contain many messages. I migrated my old ".pst" file into the new computer (that sort of worked, kind of), but I don;t know how to find and copy my other Personal Folders over.

Any help is appreciated.
