I'm having the Zimbra 8.0.2_GA_5569.FOSS version installed. It all works pretty well. Some of the users have the ability to send mails as another person. They can choose the "From" address in the web client by clicking in the from field. Now these users also want to access their mails via Zimbra Desktop. But in Zimbra Desktop they aren't able to choose the from addess. They can only send mails as themselves. Is there a hidden option I have to enable? Or does this "send as" function not work in Zimbra Desktop?
