Symptoms

When a user actions a task using email, the email response from the K2 server does not contain any information - it is a blank email.
 

Diagnoses

This can be caused by multiple entries in the K2HostServer.exe.config file.
 

Resolution

- Open the K2HostServer.exe.config file and locate the following lines:

<add path="SmartActionsSMTP" />
<add path="SmartActionsEWS" />

- Comment out the line containing SMTP, so that only the EWS line remains.

- After doing so, restart the K2 service.
