Dear @Ken,
Thank you for posting your question in the Microsoft Q&A forum.
As a moderator, I don't have the tools to investigate your specific account directly because this is a user-to-user support forum. Moderators and contributors, including external Microsoft employees, cannot directly intervene in Microsoft product features or access back-end systems. Our role is limited to providing technical guidance on reported issues, requests, or ideas. However, I will try my best to guide you as clearly as possible.
To help me assist you better, could you please help me answer a few questions below:
Could you please help me go to File > Account > then help me take screenshot full your screen so I can see your Product Information, your Excel Version and your account. Thank you!
May I ask that where the file which you want to unblock macro is stored? In OneDrive, SharePoint or in Downloads?
The Unblock checkbox only appears if the file was downloaded from the Internet, an email, Teams, OneDrive, or SharePoint.
Files created directly on your computer (New > Excel) will not have an Unblock option.
If the Unblock checkbox is missing, it means the file is already unblocked or was never blocked in the first place. Because Windows only blocks files that originate from external sources. If you create a file directly on your computer, Windows considers it an internal file, no matter where you save it.
In this case, the macros will not be blocked.
Could you tell me where your file is currently saved? I can then show you how to check if the file is actually blocked or not.
I am looking forward to your response so we can move forward with this!
