I'm having no problem at all with contact and calendar sync between WebOS 1.1.0 and 5.0.18 NE on Ubuntu 64.
The only setting I have set to anything remotely non-standard is that I have the Get Email setting set to sync every 15 minutes. Sync is done over SSL, and both Zimbra servers have commercial SSL certificates.
You may want to try setting to 15 minutes, rebooting, and seeing if things "fall into place." |
