True or False: To notify end users when an update is available for Mimecast for Outlook, select Enable 'New Version Available' Notifications.

The statement is true because enabling the 'New Version Available' Notifications option in Mimecast for Outlook is specifically designed to alert end users when there is an update available for the application. This feature ensures that users are kept informed about new versions, which may include important enhancements, bug fixes, or security improvements. By notifying users, organizations can encourage them to update promptly, thus maintaining the application's performance and security at a high standard.

Options that suggest the statement is false or pertain to different user roles do not align with the intended purpose of user notifications, as the functionality is meant explicitly for end users, not restricted to administrators or deemed irrelevant.
