Method 1: Import MS Outlook Express to Outlook 2016
If you are keen on using a free solution for converting DBX to PST files then you should use the DIY trick I’m sharing here. Microsoft Outlook provides a built-in Import feature which you need to use here. Follow the simple steps given below:
First, make sure the MS Outlook tool is closed then launch Microsoft Outlook on your system.
On the taskbar, click the File menu >Open>Import.
Go on the Import and Export Wizard then select Import Internet Mail and Addresses in the list. Then click Next to continue.
Moving On the Outlook Import Tool dialog box, select the option Outlook Express on the list. Also, check the “Import Mail” and/or “Import Address book” boxes given in front of you. Click Next to continue the process.
In the case you’ve checked the “Import Address Book” box, the Import Addresses dialog box will appear. Then you can click on any of these items from the given options:
Replace duplicates with items imported. Allow duplicates to be created. Do not import duplicate items
Finally, click Finish to start the process.
I hope this manual method will be helpful!
