Review digital certificates for a macro project

When you look at the details of a digital certificate, look at the Issued to and Issued by fields to determine whether you trust its source. Look at the Valid from field to determine if the certificate is current.

If your Macro Security setting is set to Medium or High, you will receive a warning before you open files that contain macros signed with suspicious certificates. The warning dialog box allows you to click Details to view the properties of the certificate.

To view certificates for a file that you already have open, follow these steps:

1. On the Tools menu, point to Macro, and then click Visual Basic Editor.
2. Use the project explorer to select the desired macro project.
3. In the Visual Basic Editor, click Digital Signature on the Tools menu.
4. In the Digital Signature dialog box, click Detail to view the details of the certificate.

Note  The Detail button will only appear if a digital certificate is attached to the project.
