About the "Best with" Z-Push version

For many (especially old clients) we don't get feedback from users anymore. The "best with" information marks the point where we got feedback that this client would be working. This doesn't mean it won't work with newer or even the latest version, but we just don't know.

If you are still using such a client, please send us your feedback.

Apple Mac Mail and the Exchange Server option

 Please be aware that Apple uses Exchange Webservices (EWS) and not Exchange ActiveSync (EAS) for it's connection and is therefore not compatible with Z-Push.
