Looking to Convert Files from OLM to PST using OLM Converter

Question

I was working on Mac platform for last few years but now due to some reasons I have planned to move on to Windows system again. But there is one issue I am experiencing that my database of outlook 2011 is not transferring to windows outlook. I have exported outlook 2011 database as olm files. I have tried to transfer my files using IMAP configuration but as I have a large amount of database, will it be a quick process????? IMAP configuration will surely save my money but it looks like a complicated process of database migration from mac to PC.

Now I have searched some other ways for migration on GOOGLE then I have found "http://www.olm-to-pst.blogspot.com" this link & got a olm converter. I have downloaded their free version & completely checked its working process; it works fine for me. But it asks for some payment to convert all files from olm to pst.


Will It be OKAY??? to invest in this tool.


Need Suggestions, Urgently?????
