Trust access to the VBA project object model This setting is for developers and is used to deliberately lock out or allow programmatic access to the VBA object model from any Automation client. In other words, it provides a security option for code that is written to automate an Office program and programmatically manipulate the Microsoft Visual Basic for Applications VBA environment and object model.

This is a per user and per application setting, and denies access by default. This security option makes it more difficult for unauthorized programs to build "self-replicating" code that can harm end-user systems. For any Automation client to be able to access the VBA object model programmatically, the user running the code must explicitly grant access.

To turn on access, select the check box. Office uses Microsoft Authenticode technology to enable macro creators to digitally sign a file or a macro project. The certificate that is used to create this signature confirms that the macro or document originated from the signer, and the signature confirms that the macro or document has not been altered.

You can obtain a digital certificate from a commercial certificate authority CA , or from your internal security administrator or information technology IT professional. To learn more about certificate authorities that offer services for Microsoft products, see the list of Microsoft Root Certificate Program Members. Creating your own digital certificate for self-signing. Note: Because a digital certificate that you create isn't issued by a formal certificate authority, macro projects that are signed by using such a certificate are referred to as self-signed projects.

Microsoft Office trusts a self-signed certificate only on a computer that has that certificate in your Personal Certificates store. For more information about how to digitally sign a macro, see Digitally sign a macro project. You can change macro security settings in the Trust Center, unless a system administrator in your organization has changed the default settings to prevent you from changing the settings. On the Developer tab, in the Code group, click Macro Security.

To enable the Developer tab, see Show the Developer tab. In the Macro Settings category, under Macro Settings , click the option that you want. Note: Any changes that you make in the Macro Settings category in Excel apply only to Excel and do not affect any other Microsoft Office program. You can also access the Trust Center in Excel Options. Add, remove, or change a trusted location. Add, remove, or view a trusted publisher. Enable or disable macros in Office files. Enable or disable security alerts about links and files from suspicious websites.

View my options and settings in the Trust Center. Some users may not be able to change Trust Center settings due to group security policies in their organizations. For a better experience, please enable JavaScript in your browser before proceeding.
