Change the Default Setting for the 'Send Notification Email' Checkbox on Tasks in Salesforce Classic

The following steps apply to Salesforce Classic only for organizations that do not have the 'Enable User Control over Task Assignment Notifications' setting enabled.

Steps to Change Default Send Notification Email Setting (Salesforce Classic Only)

1. Create or edit an existing Task record.
2. Click the 'Send Notification Email' checkbox to either add or remove the check.
3. Check the 'Make this the default setting' checkbox.
4. Click Save.

This default setting applies to all Task creation and edit pages under all objects and related lists throughout Salesforce Classic. The setting can be changed the next time a non-default value is selected.
Example: If you selected "false" as the default, the next time you select "true" for the checkbox, the "Make this the default setting" option reappears so you can make "true" the new default.

Important Notes and Exceptions

• This setting takes precedence over the Email Notification Checkbox settings in the "Task Layout Properties" page: "Show on edit page" and "Select by default."
• Exception — Log a Call page: On the "Log a Call" task page, there are two "Send Notification Email" checkboxes. The "Make this the default setting" checkbox does not work on this page.
• This setting is a per-user preference and does not affect other users in the org.
