Chapter 36Support for ActiveSyncSupport for the ActiveSync protocol allows users to synchronize their email, calendars, contactsand tasks with mobile devices with Microsoft Windows Mobile, Palm OS and Symbianoperating systems (for updated list of supported mobile devices, see section 36.2). The ActiveSyncprotocol is based on HTTP(S). For network connections, it uses WiFi, GPRS, UMTS andother technologies.Kerio MailServer includes direct support for the protocol and therefore there is no needto install any supportive utility if the device also supports ActiveSync. If the device doesnot support the protocol, it is necessary to install an application which allows the synchronizationon the device. Description of configuration of all particular devices is includedboth in the device’s user’s guide as well as in the Kerio MailServer, User’s Guide manual(http://www.kerio.com/kms-manual). In chapter Synchronization over ActiveSync,simple and clear instructions on synchronization settings for all supported devices are provided.And also, no settings in Kerio MailServer are required for the support. The only requirementis that the HTTP(S) service must be running on the default port (i.e. port 80 for HTTP andport 443 for the SSL-secured version). On most of supported mobile devices, ports cannot bechanged to non-standard ports.Warning: In addition to running of services on the server, it is also necessary to map correspondingports for HTTP and HTTPS on the firewall protecting the server. Otherwise, theservice will not be available from the Internet (for details, see section 2.3).36.1 Synchronization methodsFor synchronization of Kerio MailServer data with mobile devices, two methods can be applied:1. Direct synchronization with the server.2. Synchronization by using a desktop application installed on the workstation.Note: The methods can usually also be combined.Direct synchronization with Kerio MailServerThis synchronization method as well as its options and usage is addressed in chapter Supportfor ActiveSync.This synchronization method does not require connection of the device to a desktop computer.The technology allows to connect over HTTP(S) ActiveSync protocol directly to the363
