Macros blocked from running in Office 365

[Oddjob63]

I can't unblock macros in Excel even though I have made the folder and sub-folders to the file location 'Trusted Locations' and ticked 'Allow documents on a network to be trusted' in Trusted Documents.

The option to unblock macros at the bottom of the General tab of the file Properties does not appear on my file.

The file is located in a Onedrive folder.

What do I have to do to enable these macros to run?

Clear the 'Author' name in Properties:

or

Right-click the file in File Explorer | Properties - check 'unblock'
