No Emails or SmartActions are received and the Error Profiler on K2 Workspace is failing with the SMTP Error "There is no connection string for the destination email address."


Troubleshooting Steps

To resolve this issue, please complete the following steps:

Step 1

- Verify that the Environmental Libraries in K2 Workspace are correctly configured for the "From Address"


Step 2

- Verify that the entries in the Connection String Editor are set that TLS is None


Step 3

- Create a dummy email process and see if the same error appears


Step 4
