Answers.Body: <p>This (unfortunately) is expected behaviour when you have enabled Online Registration => Confirmation Email in the Event Configuration page.</p>

  <p>My interpretation of that is that some notification was supposed to be added back in 4.3 letting the user know that emails would be sent when you attempt to batch update status via profiles.</p>

  <p>It is also possible to change multiple participant statuses using the Update Multiple Participants action with a profile that includes the Status.

Body: <p>After an event at the weekend, I batch updated all 'pending due to pay later' participants to 'attended'. It appears that this triggered the re-sending of the confirmation email to all those people. Does anyone know why this might have occurred and how to avoid it in the future? We're using CiviCRM 4.6.3.</p>
