Parameter Value: [15-character Salesforce ID of an Organization-Wide Address]
Parameter Requirements: None
Parameter Description: EmailFromID specifies an Organization-Wide Address as the From identity of the email.
The Organization-Wide Address is defined in Setup → Email Administration → Organization-Wide Addresses. After setting up the Org-Wide Address, edit the record to locate the Salesforce Id. It will begin with 0D2. Each Org-Wide Address might be restricted by Profile.
When using the EmailFromId you must enable the View Setup and Configuration permission settings under the user's System Permissions in Salesforce which gives the end-user visibility, but not the ability to modify the Setup Menu.
This parameter is not for use with EmailReplytoId. They are mutually exclusive.
