SUMMARY
If you open a document that contains a digitally signed
macro, you are prompted to select whether to trust the source if the following
conditions are true:
- The digital certificate has not previously been
trusted.
-and-
- The security for your program is set to High or
Medium.
You have the option to trust all currently installed add-ins
and templates on your computer so that all files that are installed with
Microsoft Office or added to the Office templates folder are trusted even
though the files are not signed. This article describes how to specify the
trusted sources for Digital Certificates.

Specifying Trusted Sources
Using trusted sources is a means of cataloging and allowing
signed executables to run on a computer. By enabling this feature, you can
select whether to allow executable code or programs to run from sources that
can be identified or trusted.
An Administrator can select to turn
off the trusted sources feature or to enable a list of trusted sources as a
default. If this feature is selected, any future installable code (such as,
add-ins, applets, executables, and so on) is automatically copied to, or run
from, the user's computer.
To specify trusted sources in Word,
Excel, or PowerPoint, follow these steps:
- On the Tools menu, point to Macro, and then click Security.
- Click the Trusted Sources tab.
- To trust all add-ins and templates currently installed on
the computer, select the Trust all installed add-ins and
templates check box.
You can add trusted sources by accepting the request to trust
an applet or program the first time it tries to run. Macro security must be set
at Medium or High to force this request.
NOTE: The Security dialog box is available from Word, PowerPoint, and
Excel. It is not available in Access.
