When an agent creates ticket and save the service ticket and want to use email as followup activity there is no values found in the popup of followup activity.
i have maintainted all settings in customization.
1. Transaction used is Service Request and Outgoing E-mail.
2. Maintained Copy Control to Service Request and Outgoing Mail Transaction.
3. Maintained Channels for the both transaction.
Still i am unable to find email as followup through interaction center agent.
