I have just tried to setup a smartphone to sync wirelessly but cannot solve this error.
Zimbra version is 5.0.6_GA_2313, the phone is a Samsung i325 running windows mobile 6. I'm not using SSL at this stage to remove the self-signed cert issue.
The sync.log file does show a 401 Unauthorized message which from previous posts I've seen is normal, it then continues on to show the folder hierachy in XML but the phone just displays the error synchronizing message for a few seconds then back to the blank email screen.
Any help is appreciated thanks.
