we have running a zarafa server with an SSL certificate. It is an domain-cert: "*.domain.de" so we can use it for mail.domain.de, pop.domain.de and so on. We also use this cert für z-push / avtice-sync an it works well with webOS- and iOS-devices but not with WP7. As long as he WP7 is connected by wlan it seems to work, as far as the device is connected by WWAN (GSM/UTMS) the device throws errors.
So my question, are there special requirement to get a WP7 running over SSL with z-push-2.0.1 ?
