Hello, <br />
<br />
I have a customer getting the attached security notice in Excel. &nbsp;<br />
<br />
Would someone advise what that means? &nbsp;<br />
<br />
Also, what are the buttons &quot;trust all from publisher&quot; or &quot;Enable Macros&quot; represents?<br />
<br />
If I want to setup a global setting to address this using Active Directory Group policy, do you know which location I should look at? &nbsp;<br />
<br />
Thanks
