Security Risks and Precautions
Macros from unknown or unreliable sources may contain malicious code that compromise your security and privacy. The default Macro security level in Word is set to high. This setting means that if a macro does not meet one of the following two requirements, Microsoft Office Word will not allow it to run.
The macro you are trying to run must have been created using the copy of Microsoft Office Word that is installed on your computer.The Macro you are trying to run must have a digital signature from a verified and trustworthy source.
The reason that these security measures have been put in place is that people reported malicious code implanted in macros to Microsoft in the past. While this default setting is ideal for protecting most people, it will make it a bit more difficult for you to use macros from other sources that may not have digital certificates. There is, however, a workaround for those of us who need more lax security.
Word 2010 and Later
To edit your macro security settings in Word 2010, 2013, and Microsoft 365, you have several options.
Option 1
If you open a document that has macros enabled, you will see a yellow bar at the top of your screen with a button that says Enable Content, which you can use to enable the macros for that document for single use.
Option 2
If you see the yellow Enable Content bar, you can also make the document a “Trusted document” so that the macros in that document will always be allowed. If you want to make allow macros in the document follow these steps:
Option 3
You can also change the macro security settings in the Trust Center similarly to the Word 2007 method.
