ZohoCRM Outlook Toolbar and Zimbra Outlook Sync

Please be advised that I have tried unsuccessfully to install both the Zimbra Outlook Sync Connector and the ZohoCRM Outlook Toolbar don't work in the same installation of Outlook 2007.

Apparently Zimbra's Outlook Sync (the newest one that works with Outlook 2007) and ZohoCRM's outlook toolbar don't get along. Outlook fails to connect to the Zimbra server when the plug in is installed.

Please advise.
