Escalation emails fail to send out and an error appears under Workflow Server > Error Profiles.
- The same error is found in the Host Server logs:
"Error","General", "28083","ExtenderExecuteError","ProcessInstance.HandleException","28083 EscalationAction: There is no connection string for the destination email address <Email Address>.
InnerException: There is no connection string for the destination email address <Email Address>."
- There are no issues with email notifications from the Default Client Event and Email Event
- The SMTP connection strings are correct
This was resolved by re-creating the entire Activity where the escalation was configured on, and then re-deploying the Workflow.
