has anyone found a solution to enable Email forwarding, CC and BCC in Finesse email gadget.
This functionality was available in CAD but has now disappeared from Finesse.
Deleting email we can do by re-queuing into a deleted CSQ.
The feature that you are asking for (BCC and CC fields) is currently not a part of Finesse and although Finesse is trying to incorporate as much feature parity with CAD this is something that does not yet exist even in the latest version i.e., UCCX 11.
I really don't think there is any possibility to achieve this functionality by making changes to default Finesse Agent Email Gadget. However, there is a company called 2Ring that deals extensively in Finesse Gadgets for these kind of requirements and others as well. Hence, it will be worth to contact them for this and check if they have a solution
