A Salesforce system administrator is unable to enable Email-to-Case from Setup. When the checkbox to enable Email-to-Case is selected and the Save button is clicked, the system displays the following internal server error (the error ID number in parentheses may vary):
An internal server error has occurred. An error has occurred while processing your request. The salesforce.com support team has been notified of the problem.

Please indicate the URL of the page you were requesting, any error ID shown on this page as well as any other related information. We apologize for the inconvenience. Thank you again for your patience and assistance. And thanks for using salesforce.com! Error ID: 492678312-64701 (325062378)
One or more of the Case page layouts contains duplicate quick actions. Duplicate quick actions in Salesforce Case page layouts prevent Email-to-Case from being enabled and trigger an internal server error on save.
When Email-to-Case fails to enable with an internal server error, the underlying cause is typically duplicate quick actions on one or more Salesforce Case page layouts. To resolve this issue, clear the quick action list for the affected layouts by following these steps:
Note: If the error persists after reverting one layout, check all remaining page layouts and revert each one. Simply removing duplicate quick actions without reverting the layout may not fully resolve the issue.
