Phishing Email Protection in Microsoft Outlook

To enable the phishing email protection built into Outlook:
  1. In Outlook 2003/07:
    • Select Tools | Options… from the menu in Outlook.
    • Click Junk E-mail… on the Preferences tab.
  2. In Outlook 2010/13/16/19:
    • Open the HOME ribbon.
    • Click Junk in the Delete section.
  3. In Outlook 365:
    • Click on Home tab
    • Click on 3 dots (…) at far right
    • Hover over Junk then click on “Junk E-mail Options…”
Change the level of junk email protection.
  • By default, the Junk E-mail Filter protection level is set to No Automatic Filtering. You can make the filter more aggressive so that it catches more junk messages. For most casual e-mail users, the “Low” setting should be enough to catch most junk e-mails. The higher you set the protection level, the greater the risk of some legitimate messages being identified as junk and moved to the Junk E-mail folder.
  1. Under the Options tab, make sure the Outlook recommended checkbox is selected.
    • Outlook 365 – “Warn me about suspicious domain names in email addresses.”
    • Outlook 2007-2009 – “Disable links and other functionality in phishing messages.”
    • Outlook 2003 SP2 – “Don’t turn on links in messages that might connect to unsafe or fraudulent sites.” (Outlook 2003 SP2)
  2. Safe Senders – Under this tab you can specify certain email addresses or email domains to never be treated as a Junk message.
  3. Safe Recipients – Under this tab you can specify certain email addresses or email domains you sent to never be treated as a Junk message.
  4. Blocked Senders – Under this tab you can specify certain email addresses or email domains to always be marked as a Junk message.
  5. International – Under this tab you can select which countries of origin to block. Please use caution when adjusting settings under this tab. OIT recommends contacting the Help Desk for assistance/guidance before making any changes under the International tab.
  6. Click OK once you are satisfied with any/all changes made under the Junk E-mail Options window.
