This has been a point of great confusion, if only for me.
I am running ZCO client 6.0.5736.2 and Server 6.0.2_GA_1912
Read receipts sent from anywhere, including another ZCO, Zimbra webclient, or Outlook client on Exchange are not acknowledged by a ZCO recipient(no message pops up saying the sender is requesting a read receipt with the option to send it or not). Outlook is configured to prompt user. Is this functionality expected or should this combination be working? I was led to believe we have full read receipt functionality...Thanks i advance for any explanation.
