In the interest of combating ransomware and other malware, Microsoft is planning a major change in how its Office software handles macros: when files that use macros are downloaded from the Internet, those macros will now be disabled entirely by default. Current versions of the software offer an alert banner on these kinds of files that can be clicked through, but the new version of the banner offers no way to enable the macros.

The change will be previewed starting in April in Office version 2203, before being rolled out to all users of the continuously updated Microsoft 365 version of Office starting in June. The change will also be enabled for all currently supported standalone versions of Office, including versions 2021, 2019, 2016, and 2013. The Mac, iOS, Android, and web versions of Office won't be affected.
