Is there a way to turn off Microsoft Outlook out-of-office reply emails when a request is sent to a team and a member of the team is on vacation?

Not sure if this is a Microsoft Outlook setting or a Workfront one. A member of a request queue team is on vacation, and her out-of-office replies are going to people who submit requests in Workfront. Is there a way to stop those automatic emails from sending because it's giving the impression that the request won't be worked on until she returns from vacation?
