Recommended validation or troubleshooting step
- Confirm the business owner and source of the macro-enabled file/template. - Check whether the file is marked as downloaded from the internet and whether approved trust workflows exist. - Use signed macros or approved trusted locations according to enterprise standards. - Do not disable macro security globally or advise users to bypass security warnings.
Review carefully before proceeding
- Business-critical macro workflows require policy exception or code signing support. - Multiple teams are blocked after Office security policy changes. - Security review is needed before enabling execution for high-risk documents.
