I have Z7.1NE configured and working with different mobile devices. I have one account where the calendar just would not sync to an android device. I have tried both the built-in exchange client and the touchdown app to no avail. I suspect an active-sync error, maybe a special character in the calendar name or that type of thing. Does ActiveSync have its own error log? I can not find any errors in mailbox.log. Where should I start troubleshooting ActiveSync?
