As the converter final step shows that I have completed the conversion process, I am concerned on how do I import these files in outlook 2010. Is there any addon that I need to use as in thunderbird or there are any direct methods to do it...???

Thanks for the guided solution.

All mentioned email applications used MBOX file to store the user mailbox data. Unfortunately, there is no inbuilt Outlook import option available for MBOX to PST file conversion. But there are various mbox to pst converter software available on web. You can easily search in Google about these software :- http://www.filesrepairtool.com/mbox-to-pst-converter.html
