Kopano provides email storage on the server side and brings its own
Ajax-based mail client called WebAccess. Kopano is designed to
integrate with Kopano WebApp, Push clients and other mail services as an
alternative to Microsoft Exchange and other comparable mail servers.
Personal address book, calendar, notes and tasks, "Public Folders" and shared
calendar functionalities (inviting internal and external users,
resource management) can be handled by the software as well.
