Beware of the gamble you are taking. We use Microsoft Outlook Webacces 2007 and this will NOT work for our company webmail. Ive confirmed its owa 2007. Ive read the email and have entered the info as indicated but get failure to synchronize and he log shows invalid host. Now Ive spent $7.99 for nothing. Can I have my money back?? Doubtfully. Adding onto this.. I filled out a problem ticket and now 32 days an still no response of any kind. Not even an acknowledgment. It it were possible to give zero stars that would be my rating. It pops up alerts that "I have mail in my inbox" but never does connect and get it. I more and more think this is a scam. DONT fall for it
