The functionality Email-to-case is not working for me. When I am sending a Case to e-mail, a new case is not created. I am using the long service e-mail. When I changed the Automated Case User to myself I am getting following error to my e-mail:
The following errors were encountered while processing an incoming email:
FIELD_CUSTOM_VALIDATION_EXCEPTION : No permission to send the Email based on the Case.
I found an answer that a Validation Rule is causing it, does somebody know how to come to the point on which object this validation rule may be? I have thousands of objects and validations rules on my org...
Thank you in advice for any tip!
