I would rate this as a zero if I could.

I was so excited to find this post as I just bought my first Mac, a new MacBook Air, and quickly ran into the iCal to Outlook problem. I bought and downloaded Zamain for Mac, installed it, went thru each of the steps, but it didn't work. I used the Contact Us link on the Zamain website and described the problem, asking for help to get Zamain for Mac working. Once that was submitted a page popped up saying I'd be contacted within 2 bus days and probably sooner. Two days later, no contact, so I submitted another request for help the same way. There is no direct email, phone number or chat capability, only the Contact Us link. Now it's been 5 days since the first request and 3 days since the second one. No contact, Zamain still doesn't work. So I sent a request thru PayPal to get the support I needed from Zamain to get the software working, and if not, I needed a refund. Within a few hours, a refund showed up. No one from Zamain ever contacted me to even try and figure out why their product would not work. Really disappointed.

So don't buy this product. It doesn't work. Maybe it used to but it doesn't now!
