We have a programmer that needs that option checked but it is greyed (ghosted, disabled) and cannot be changed.
If we go to Excel or Word that option can be enabled or disabled by a click. Unfortunately, we cannot enable it.
Also, in Access, Excel and Word the Macro Security is set to Low.
I have changed the Macro Sercurity in Access to High then it prompts me to restart the program I do, then change it back to Low and restart and still no option to check the box.
