Then decide how you want to better control Office files. First, download an appropriate Group Policy administrative template. With Group Policy settings, administrators have been able to block macros by default as far back as Office 2016. You should also evaluate if you want to take actions to block other macro settings using Intune with Azure Active Directory or Group Policy with Active Directory. At a date to be determined, Microsoft plans to make this change to Office LTSC, Office 2021, Office 2019, Office 2016 and Office 2013. Later, the change will be available in the other update channels, such as Current Channel, Monthly Enterprise Channel, and Semi-Annual Enterprise Channel. The change will begin rolling out in Version 2203, starting with Current Channel (Preview) in early April 2022. This change affects only Office on devices running Windows and Access, Excel, PowerPoint, Visio and Word. If you’ve downloaded macro-based templates from websites, mark these files as trusted and remove the “mark of the web” from the files to ensure that they continue to work. Setting this as the default will mean that you’ll be better protected. Specially, Visual Basic Application obtained from the internet will be blocked by default. Launching malicious macros is a common way that attackers can gain access to computer systems and launch lateral attacks. The first major change in an Office 365 default blocks internet macros by default. This includes blocking macros by default, limiting native tools used by attackers, and activating Credential Guard by default. Microsoft changes default settings for a variety of reasons, but some recent key changes will keep us safer from attacks, specifically ransomware.
