Hi i have a very simple email publisher to replace the original one :->
<apex:page standardController="Case"><apex:emailPublisher entityId="{!case.id}" fromVisibility="selectable" subjectVisibility="readOnly" toVisibility="readOnly" fromAddresses="support@abc.com}" emailBody=""/></apex:page>
So i remove the standard 'Answer Customer' action and add in my custom emailpublisher in. Now all my email message record feed doesn't have the 'Reply'& 'Reply to All' button. What have i missed out? Basically what I want to achieve is I want the sender to default as our support email instead of user's personal email.
With Answer Customer Action
