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.
