In an effort to strengthen the email spam filter to block more spam email and better prevent email-borne threats from reaching the inboxes of our end-users, UTD migrated to Microsoft Office 365’s Exchange Online Protection (EOP) and Advanced Threat Protection (ATP) on Friday, July 19, 2019. Changes to allow and block lists in IronPort were migrated to EOP, with the exception of changes made to the lists after July 8, 2019.
UT Dallas uses Microsoft Office 365’s Exchange Online Protection (EOP) to scan and quarantine suspected spam, phishing, and malicious messages before they reach your inbox.
Office 365 email at UTD also includes Advanced Threat Protection, which includes powerful safeguards like Safe Links, which provides time-of-click protection to help prevent users from opening or accessing malicious links, and Safe Attachments, which protects users from opening malicious email attachments. More information on these services is below.
Safe Attachments provides additional protection from files that may contain viruses, phishing links, or other malicious content by opening and testing them in a virtual environment before delivery. Messages sent to UTD Office 365 e-mail inboxes with malicious attachments will be blocked by Safe Attachments.
Links that are not on the UTD whitelist will be rewritten to include Safe Links protection. The way you see the link depends on the message and the client used to send the message:
HTML email will have a less noticeable impact. The original URL will show in most places, but when accessing mail via the web you will see the longer Safe Links URL in the browser footer (or elsewhere depending on the browser)
When clicking a Safe Links protected link, most of the time you will go directly to the original link. However, at times you may see one of the below warning screens. If you have questions about the legitimacy of a link flagged by Safe Links, please contact the Help Desk.
A URL is being scanned by ATP Safe Links. If you encounter this page, it is best to wait for a few minutes for the scan to complete and then try reloading the page.
The URL is in an email message that seems similar to other email messages that are considered suspicious. We recommend that you double-check the email message before proceeding to the site.
The URL is in an email message that has been identified as a phishing attack. As a result, all URLs in the email message are blocked. You should only proceed to the site if you are positive that it is safe.
The URL points to a site that has been identified as malicious or that has been specifically blocked by UTD. You should only proceed to the site if you are positive that it is safe.
