Hi @RCDA Webmaster ,
Please first understand here we mainly focus on general issues about Outlook desktop client and know little about Windows live Mail. As I know, there may be no option in Outlook that could import the .eml file directly except dragging it to the folder.
However, based on my research, I found a relevant article that mentioned we could install the Outlook in original PC and import your message from windows live mail to Outlook directly, then we could export a .pst file in Outlook and restore it in your new PC. For more detailed information, please refer to the Scenario 2: Outlook is located on another computer and Migrate Mail part of the article mentioned above.(Please Note: Since the web site is not hosted by Microsoft, the link may change without notice. Microsoft does not guarantee the accuracy of this information.)
Hope that would be helpful to you.
