When setting up a Split domain system, setting zimbraMailTransport to an external smtp server eg (smtpther.smtpserver:25) via the admin console, Free Busy information for the account becomes unavailable through the Web client, Outlook connector etc.

Is this normal behavior? I would consider Free/Busy to be a separate function/feature to which mail server is used.

Is there a way to over ride this functionality as my reason for adding Zimbra is primarily the Calendar, Tasks, GAL, Free/Busy to replace an existing system. And I need to be able to set it up and move accounts across from the old server to Zimbra in a managed process. Currently without the Free/Busy, there is less reason to migrate,

Can any body help me here?
