Outlook 2010 and 2013 MailTips Options
Microsoft Outlook 2010 and 2013 include MailTips, which help you avoid common, but potentially costly or embarrassing mistakes. MailTips alerts can be triggered by actions including clicking Reply All to a large recipient list, sending sensitive information to someone outside your organization, or sending a message to someone who is out of office.
Note This feature requires a Microsoft Exchange Server account. For more information see, Determine the version of Microsoft Exchange Server my account connects to.
