I am a technician in a town hall and we have a Zimbra mail server. We also have iPhone, Android and Windows Mobile 7. All these phones synchronize with 3G and everything is good . There is only one problem: If you enter an appointment on your windows mobile phone on 7, it is not synchronized in your Zimbra calendar. The mail function in the 2 direction, but not appointment ???!!!
Have you any idea?, we tried everything but at the same time, we quickly made the turn, the parameters are very simplified, a little too much when there is a problem :-)
thank you in advance.
