When we reply to calls that have been Automatically logged in Service desk via the mail fetch, it always populates the CC field with the account the emails were originally sent to.
To try and clarify, I've created an account called ServiceDesk which is used for the mail fetch, this receives a copy of all emails sent to our main support email address (
ITSupport@mycompany.com). The calls are automatically logged just fine but whenever a technician reply to an automatically logged call,
ITSupport@mycompany.com is inserted as a CC recipient.
