I'm moving Outlook 2010 to a new computer. There are two POP email accounts in Outlook. However, there are three PST files: email1.pst, email2.pst, and outlook.pst. email1.pst and outlook.pst are about the same size. email2.pst is small since the account is not used much. All three pst files are valid and in use since all three have today's date. I've moved Outlook plenty of times in the past, but this is the first time I've moved Outlook 2010 or later. How do I use three pst files for two email accounts? Is outlook.pst a combination of email1.pst and email2.pst?

If you look in the folder list on the left side, and right click on each email account and select Data File properties/Advanced, you can see which pst file is used for which email account. You can also go to File/Account Settings Email tab and highlight an email account and look down below to see where that account is delivering mail to.

It is possible that one of those pst files is not associated with an email account, and only holds contact and calendar info.
