Import the PST file


In Outlook you have the import functiontality in the File menu.

It will open a window with multiple options, select Import from another program or file.


Select Outlook Data File (.pst) in the next step.

How to get it

You can get the software directly from their website:

The software is not free, you can test the software and see the emails in the interface but you are not able to import the emails to Outlook until you can get a license.

  • The Coporate license is for multiple machines at multiple geographical and the Home license for individual/personal use only locations.
  • With the Coporate license you can export MBOX files to Office 365 mailbox, with the Home license you can't.
  • With the Corporate license you can saves MBOX emails to email servers (GroupWise, Exchange, & Domino) with the Home license is not possible.
  • The price for the Home license is $39 and for the Coporate license is $199.

If you are interested to get this software or others, I recommend you to check first the offers in the website.


Kernel MBOX to PST is a software very easy to use and install, also you have all the options in the main interface and the help manual is extensive and helpful. But the software is only for Windows, I use Microsoft Office on Windows and Mac, this means I have to use Windows to convert the emails and move the emails to my Mac if I want to have the emails, will be nice have the OS X option, for these reason I give to this software a 9/10.
