MDaemon Messaging Server* includes support for Microsoft ActiveSync, which is a separately licensed over-the-air (OTA) ActiveSync (AirSync) server. ActiveSync provides native synchronization of a user's default email, calendar, contacts, and tasks data between their MDaemon & Webmail (WorldClient) account and an ActiveSync capable device. Other features include: Remote Wipe, Auto-Discovery, Multiple Folder Synchronization, Global Address Lookup, and SSL Encrypted Transmissions.
ActiveSync for MDaemon installs along with MDaemon but it is a separate product from MDaemon and will only run as a trial for 60 days. After that, a one-time fee is required. The 60 day trial begins when you install MDaemon and enable ActiveSync for the first time.
*ActiveSync does not work with MDaemon Standard version.
In MDaemon, ActiveSync can be enabled via a checkbox under the Setup | Web, Sync & IM menu.
