I wrote a small program to import Google Contacts (and maybe iOS contacts) to MailEnable. It's open source and free. It was quicker for me to write a program than to make all the changes to my contacts after using the ImportICS.exe program.

Download it from GitHub: https://github.com/phoenix125/GoogleContactsToMailEnable
or directly from my website: http://www.phoenix125.com/share/mailenable/GoogleContactsToMailEnable.zip

Windows Defender Note! Most of my programs written in AutoIT get flagged by Windows Defender as containing a virus. I submit them to Microsoft and they get added to the Defender exception list, but it takes up-to 30 days for users' virus definitions to get updated.
You can always test my programs at https://www.virustotal.com/gui/ or look at source and recompile.
Enjoy! I love MailEnable!
