Exchange Sync working on iOS but not OS X?

Exchange Sync works on iOS but not OS X’s Mail Application.

https://name.tld/autodiscover/autodiscover.xml is reachable and so is

Mail says “could not connect” and “The Exchange server is not responding”.

Am I doing something wrong or does z-push not support OS X’s Mail?

The Z-Push website doesn’t list OS X on their compatibility page so I guess it’s IMAP and POP only then.

I’ve added a link to the compatibility list in the setup guide: Thanks for looking into the issue.
