2022-09-27MC How AffectPreviously, it was possible for end users to enable these macros by simply clicking a button on the Trust bar.
Now, with this change, once a user opens an attachment or downloads from the internet an untrusted Office file containing macros, a message bar displays a Security Risk that the file contains VBA macros obtained from the internet with a Learn More button.
[Picture of the red business bar should be added here.]
The Learn More button goes to an article for end users and information workers that contains information about the security risk of bad actors using macros, safe practices to prevent phishing and malware, and instructions on how to enable these macros (if absolutely needed).
