Today’s spam and malware attacks are sometimes so well-crafted they
may look legitimate to users, and putting messages into the Junk Email folder
isn’t enough. Microsoft has been rolling out Safety Tips in Exchange Online
Protection, an additional layer of protection for all users that provides a
warning to the user in an email that is marked suspicious, or a reassurance
when a message is safe.
When a message includes a safety tip, the tip will be displayed in a
messaging bar at the top of the email in one of four color-coded
categories indicating that the message is either Suspicious, Unknown, Trusted
marked Suspicious have a red safety tip and are either a known
phishing message, have failed sender authentication, are a suspected
spoofing message or have met some other criteria that Exchange Online
Protection has used to determine the message is fraudulent. You should not
interact with suspicious messages and instead should delete them.

organization, is on the user’s safe senders list or Exchange Online
Protection marked the message as junk but the user moved it out of the
junk folder to the inbox. The gray safety bar also appears when images
within the message have been disabled.
All four types of Safety Tips are included in the Outlook on the web
experience, whereas Outlook clients, whether desktop or mobile, will display
only the Suspicious safety tip. Most messages in your inbox will not have a
safety tip; we only add them when we have information users need.
How does Microsoft determine which Safety Tip
As an industry-leading solution for securing your email, Exchange Online
Protection analyzes data patterns across millions of emails to identify spam,
malware and phishing threats. Based on this ongoing analysis, Exchange Online
Protection is able to identify suspicious messages and apply the appropriate
Users can also report misclassified messages back to Microsoft for
analysis. They will take these samples and use them to make user experience
Safety Tips are an important tool in combating phishing scams and online
fraud. With this new functionality, Office 365 automatically provides an
additional layer of protection for all its users. Microsoft will continue to
enrich the Safety Tips feature to ensure their users have the best experience.
