Thanks for your help but I've tried with the 3 days trial so I think it's useless to pay for premium, it's the same, it wont works

With Gmail and Mail For Exchange, sometimes it works but since yesterday, nothing.
Always "Exchange server not responding" even if I only activate contacts sync ( no mail, no calendar )


Edit : Just had to try again several times and now it's working with nuevasync but some contacts details are missing (msn) but it's ok ! thx !
