Zoho Calendar sync with Outlook 2010

Zoho Calendar sync with Outlook 2010

PLEASE answer these questions  specifically and not in some subset form in the way that several contractions seem to exist in other forum replies on this topic.  

I have Outlook 2010 in Internet Mail Only (IMO) mode - meaning no Exchange server - as a part of 64-bit Office 2010 running on 64-bit Windows 7.

When will I be able to reliably sync my Outlook Calendar with Zoho Calendar ?

What aspect(s) of this environment do Zoho developers consider troubling or uninteresting to not prioritize this change after 3+ years ?

Not interested in hearing how it does work on other computers, especially when stated like "Zoho Calendar syncs with Outlook" when one really means with Exchange, with 32-bit operating systems or with Outlook 2007.

Thank you.
