SECURITY RISK related to macros on Excel

Dear all,

Since 3 weeks i have an issue with my Excel sheets that are using macros in my Onedrive. Each time i open one i have this pink message :

SECURITY RISK Microsoft has blocked macros from running because the source of this file is untrusted

I have searched on internet for solvings but i don't have access to the security box in properties and i have tried everything in the Trust Center

I spent 2 hours with the microsoft support and we uninstalled and reinstalled office 365 but i have still the issue

So they told me to ask here my issue,

Thank you for every answer,

Best Regards
