Other projects
This old project is not actively developed any longer
There exists a project which is working on a ActiveSync connector, but it is not yet production quality. It is based on an older version of z-push that has an incompatible license (GPLv2 only) with newer z-push versions (AGPLv3 only).
There is now another project under way xbgmsharp / sogosync which is based on z-push 2.0. It is currently in beta stage (2012-09-12).
- It will probably also have the limitation of one calendar and address book setup only. Although the protocol supports multiple calendars and address books, most phone implementations don't.
At the moment you will probably get better results with Syncml
The advantages
- Almost all mobile devices have built-in support that get a lot of testing.
