Diagnoses

Error indicates that there where some settings that are not correct for SmartActions.

 

Resolution

Create a dedicated account and mailbox for SmartActions and reconfigure K2 to use this new dedicated account.
•In other words, make sure the K2 Host Server service is actually running as the K2 Service account on the K2 server.
•The service account must never be a destination in a workflow. You would check this in your "Windows Services" -> K2 blackpearl Server Properties -> Log On.
•Check your String Table in Management Console - K2 Server - Workflow Server - String Table - String Table (environment)
Make sure the Mail Server and From Address strings are set to the correct values
•Also check your Environment Fields in Management Console - K2 server - Environment Library - Templates - Default Template - Environment - (select environment) - Environment Fields
•Check all "Mail Server" Field Types - ie. "From Address" and "Mail Server" (make sure that's all of them) are set to the correct values, change if necessary. If it still doesn't work, delete/remove these values, then recreate them from scratch.
