“Hi there, my name is Dane Thompson, and my father has been using Outlook Express on Win XP for many years. Recently, I had him upgraded to Windows 10, which has Office 365 and Microsoft Outlook. I have his old Express data stored in DBX files on the PC and as a backup on a USB, but to access it in Outlook, I require them in PST format.
