I have a client who was previously using Zimbra and there is one user whose system keeps forcing him offline (after over 2 years of not using Zimbra) with a zimbra settings mismatch error. This happens pretty much continuously and the user's Outlook is unusable.
I've done a repair install of Outlook and uninstalled / reinstalled / uninstalled / reinstalled the ZCS connector and we're still having issues.
Where is the registry information that Outlook keeps reading so I can just fix it manually? The uninstaller obviously doesn't seem to do anything useful.
