At Macworld Expo this week, Kerio Technologies has been demonstrating Kerio MailServer 6.5, its cross-platform mail and calendaring service for Windows, Linux, and the Macintosh aimed at small- to medium-sized businesses and organizations.
Version 6.5 will feature an all-new Kerio Outlook Connector for Windows users, as well as a new integrated CalDAV service that purports to eliminate the problems that usually crop up when users of different calendar applications (like Microsoft's Outlook and Entourage, Apple's iCal, and Google Calendar) try to schedule meetings. Kerio MailServer 6.5 also centralizes all calendars so remote users accessing information via Web-based mail or mobile devices can always get the latest information.
Kerio hasn't announced a release date for MailServer 6.5, but the product has been in beta testing and the company has posted its first release candidate, so a final version could be coming soon. Kerio MailServer has a base price of $399 for 10 users; subscription pricing is also available.
