ZOC With Outlook 2010 not syncing contacts/cal
We've just got the Zimbra server installed and everything is working largely okay with one problem. I've tried with 3 seperate machines (OS/Arch) to use Outlook 2010, email works fine, but contacts or the cal are not syncing at all. You can create contacts or appointments in the web or outlook, they never sync together. I've tried this with Outlook 2010 x32 and x64, on XP and Windows 7. On Vista x32 with Outlook 2007, everything seemed to work fine.
I've turned on logging on ZOC and nothing really jumps out at me as being the cause. Is this a known issue, and what are the best steps to go about debugging the issue?
Thank You in advance.
