User has an internal and external Forms server.  The email link that Forms sends for user tasks, is set to the internal site but the participant users have a licence on the external site.  If the user clicks the link and changes it to the external site, it works.  Updated the cf_options, restarted the Forms Routing service, and recycled the 
FormsAppPool.  Link is still using the internal site.  Forms 10.2.  Any ideas how to get the link to update to the external site?

FromsHost  http://internalserver/forms

FormsHostEmailOverride https://externalserver/forms

FormsURI https://externalserver/forms
