Unity 4.x with UM:
When UserA sends UserB a voicemail it would show up in UserB's mailbox as coming from UserA's email address. UserB could then hit reply, and then type a response back to the voicemail and send it off.
UnityCN 8.5 with Single Inbox:
UserB still gets the email with wav file, but it shows the sender's email address as the unity connection server, and not UserA's email address.
Is there a way to make this function like Unity and replace the default "Unity Connection" email with the corporate email of the user leaving the voicemail?
