LSU Health - Office 365 - Safe Links
We have implemented a new solution from Microsoft called Advanced Threat Protection (ATP) Safe Links to protect our users from malicious links received by email. Safe Links re-writes links in your email message so that protection can be applied when you click the link. If a link is deemed harmful, it will block access to that link. This feature will protect users even if they are accessing the links from their mobile devices or when they are off of the LSUHSC network.
For many email messages, you won’t immediately notice any changes. The browser links will look like they normally do. But if you hover your mouse over the link, you will see the address now points you to a safelinks.protection.outlook.com address.
If messages are sent in Plain Text format, the full link will be shown in the message.
If Microsoft or LSUHSC find a link to be malicious, we can block users from getting to that link. Even if the link is harmless when the message is first sent, a malicious agent could change the destination to contain harmful content (such as a login page to steal your credentials). By using a Proxy address, the original link is checked at the time the user clicks it, to determine if anyone has reported it as suspicious.
If a link has been determined to be harmful, you will see one of the following messages:
If blocked by Microsoft:
If blocked by LSUHSC:
Remember to only click links in messages sent by a reliable and verified source. If the sender’s email address looks suspicious, or the message itself doesn’t look right, don’t click the link without checking with your local computer supporter, or Postmaster. Safe Links provides extra protection, but does not guarantee that all links are safe.
If you ever click on a link, and it takes you to anything suspicious, close the browser and follow appropriate procedures. Click the link below for associated compliance documentation:
Safe Links will only re-write links for messages sent to users in a Safe Links policy. If you compose an email to an external user that contains an ordinary link, it will not rewrite the link unless their organization is also using Safe Links. However, if you forward an email that contains a re-written safe link, it will send that same link through to your recipient. These re-written links are available to anyone who gets them – so any links you send people should work for them whether they are re-written or not.
Please note that using the option below bypasses the additional layer of security afforded by Safe Links and should only be used in an urgent situation when Safe Links are not working.
- Navigate to http://www.o365atp.com
- Paste the link in the email into the upper box titled: “Paste SafeLinks URL:”
- Copy the resulting “Decoded URL:” into the address field of your browser and hit the “Enter” key.
ATP Safe Links will not rewrite links for our own domains: lsuhsc.edu and lsuh.sc
