Group policy settings
The Group Policy Settings were announced in July 2021. Now, Microsoft has added few latest policies settings option to this Group Policy Settings. An option to direct the policy settings in the Office cloud policy service has also been added.
Administrators can completely block XLM macro usage and the new files that are created by the admins, by turning on the Group Policy, “Prevent Excel from running XLM macros”. The same can be done using registry key or Group Policy Editor. This might also make XLM and VBA malware threats less severe for the admins.
