GroupDocs.Conversion doesn’t support conversion to PST file format at the moment. However, we’ve logged an investigation (CONVERSIONNET-4810) in our internal issue tracking system to see if this feature could be implemented in future.

Manual ways to convert EML to PST:

Using Windows Live Mail and Microsoft Outlook

  • Launch the MS Outlook and Windows Live Mail applications on the system.
  • In Window Live Mail, click on the File tab and from the export option select the Email messages.
  • Select the Microsoft Exchange as the export option and click on the Next.
  • A Pop up will display on your screen that all e-mails will be exported to Microsoft Outlook/Microsoft Exchange.
  • Click OK.
  • Using the Select folders option, you can choose either you want to export all email folders or select the particular folder that you want to export.
  • Click OK.
  • After completing successfully, an Export complete wizard will come, click on the Finish.

Using MS Outlook Application, Drag & Drop
The method is preferred when EML files are separately saved on the computer and not any EML supported email client is installed on the system to access them.

  • Firstly, open Outlook on your System.
  • Navigate the location of EML files, and then select the file.
  • Drag the selected EML file.
  • Drop it into Outlook Application.
  • By doing this, you will be to able open & view it into Outlook application.

Outlook Express to Migrate EML to Outlook
At first, configure the EML files with Outlook Express by dragging in it and. After configuring, follow the below-written instructions.

  • Launch Microsoft Outlook on your system.
  • Click on the File tab, select the Open and Export.
  • Then click on Import/Export.
  • Choose Import Internal Mail and Addresses >>Outlook Express >>Next >> Click on the Finish to export .eml files to Outlook.

Hope you get to know how to do it.
