Outlook data files changed name when I changed to MAPI

I have several new data files which were created when I changed to MAPI, depending on what I named the email file. For example, I wanted to name it Personal Mail, but that didn't work. Now I have named it with the actual email address. The data files get named Outl, followed by a long name starting with the email address and followed by many zeros and another number, then .pst. At that point, all emails were lost after the date I did this.
