MAILSITE SERVES EMAIL, CALENDAR AND CONTACTS TO OUTLOOK 2007 WITHOUT PLUG-INS

NEW LOW-COST ALTERNATIVE TO MICROSOFT EXCHANGE IS NOW AVAILABLE

Campbell, CA -July 30, 2007 - MailSite Fusion, the leading low-cost alternative to Microsoft Exchange, is now available. This new release is a major upgrade to MailSite and for the first time includes a calendar and contact server in addition to a robust and proven email server. MailSite Fusion provides most of the functionality of Microsoft Exchange but costs approximately 20% of its price.

MailSite Fusion has been designed to work extremely well with Microsoft Outlook 2007. Not only does MailSite provide an excellent email server for Outlook 2007, but now calendars and contacts can be synchronized as well. This functionality is provided natively in MailSite and does not require any plug-ins for Outlook.

MailSite Fusion is also compatible with other calendar clients such as Apple Mac iCal, Google Calendar, Microsoft Windows Vista Calendar and Mozilla Sunbird. This makes it easy for MailSite users to share their calendar with co-workers inside the business as well as friends, family and colleagues outside the company. Full calendar details or just free-busy information can be shared this way. This makes it possible to truly collaborate for the first time with people in your intranet and your extranet.

MailSite Fusion includes a new web client called MailSite ExpressPro that has been developed from the ground up using the latest AJAX web technology. The look and feel of MailSite ExpressPro is very similar to Microsoft Outlook. Users who are familiar with Microsoft Outlook will be immediately comfortable with MailSite ExpressPro. MailSite ExpressPro works with all major web browsers including Apple Safari 3, Mozilla Firefox 2 and Microsoft Internet Explorer 6 and 7.

MailSite was voted as one of the top three email servers by readers of Windows IT Pro Magazine in September of 2006. With its long and successful track record as an email server, MailSite naturally works very well with all email clients including Microsoft Outlook , Outlook Express, Microsoft Windows Vista Mail, Apple Mac Mail, Mozilla Thunderbird and Qualcomm Eudora.

"MailSite Fusion marks a milestone for the Company," said David Ferris of Ferris Research. "There is definitely pent-up market demand for a viable and inexpensive alternative to Exchange, preferably one without desktop plug-ins for Outlook. MailSite Fusion satisfies that demand."

"The front end of MailSite Fusion is a fantastic web 2.0 implementation - easy to use and straight forward. End-users are going to love all of the new native Outlook 2007 calendaring functionality; especially since no plug-ins are required," said Eric Crutchlow, CEO of Gelfuzion, Inc., a long time MailSite customer. "With respect to the back-end, we all know who the 500 pound gorilla in the room is when it comes to maintenance nightmares. MailSite Fusion truly is stable and resilient when disaster strikes."

"This is the most significant release since we shipped MailSite Version 1," said John Davies, President and CEO. "MailSite Fusion breaks down the corporate walls between employees and family and consultants and makes it possible to truly share calendars for the first time. This capability is just not possible with the competing proprietary products," continued Davies.

MailSite Fusion is free for 20 users and starts at $495 per year for 50 users. Anti-spam and anti-virus subscriptions are available at additional cost. MailSite Fusion is available immediately from MailSite Software, Inc. and from resellers around the world. For more information visit http://www.mailsite.com.
