Macros Enable or disable in Office documents
Enable or disable macros with the Trust Center
Macro security settings are located in the Trust Center. However, if you work in an organization, your system administrator might have changed the default settings to prevent anyone from changing any settings.
NOTE When you change your macro settings in the Trust Center, they are changed only for the Office program that you are currently using. The macro settings are not changed for all your Office programs.
Which program are you using?
ACCESS
- Click the Microsoft Office Button
, and then click Access Options.
- Click Trust Center, click Trust Center Settings, and then click Macro Settings.
- Click the options that you want:
- Disable all macros without notification Click this option if you don't trust macros. All macros in documents and security alerts about macros are disabled. If there are documents with unsigned macros that you do trust, you can put those documents into a trusted location. Documents in trusted locations are allowed to run without being checked by the Trust Center security system.
- Disable all macros with notification This is the default setting. Click this option if you want macros to be disabled, but you want to get security alerts if there are macros present. This way, you can choose when to enable those macros on a case by case basis.
- Disable all macros except digitally signed macros This setting is the same as the Disable all macros with notification option, except that if the macro is digitally signed by a trusted publisher, the macro can run if you have already trusted the publisher. If you have not trusted the publisher, you are notified. That way, you can choose to enable those signed macros or trust the publisher. All unsigned macros are disabled without notification.
- Enable all macros (not recommended, potentially dangerous code can run) Click this option to allow all macros to run. This setting makes your computer vulnerable to potentially malicious code and is not recommended.
EXCEL
- Click the Microsoft Office Button
, and then click Excel Options.
- Click Trust Center, click Trust Center Settings, and then click Macro Settings.
- Click the options that you want:
- Disable all macros without notification Click this option if you don't trust macros. All macros in documents and security alerts about macros are disabled. If there are documents with unsigned macros that you do trust, you can put those documents into a trusted location. Documents in trusted locations are allowed to run without being checked by the Trust Center security system.
- Disable all macros with notification This is the default setting. Click this option if you want macros to be disabled, but you want to get security alerts if there are macros present. This way, you can choose when to enable those macros on a case by case basis.
- Disable all macros except digitally signed macros This setting is the same as the Disable all macros with notification option, except that if the macro is digitally signed by a trusted publisher, the macro can run if you have already trusted the publisher. If you have not trusted the publisher, you are notified. That way, you can choose to enable those signed macros or trust the publisher. All unsigned macros are disabled without notification.
- Enable all macros (not recommended, potentially dangerous code can run) Click this option to allow all macros to run. This setting makes your computer vulnerable to potentially malicious code and is not recommended.
- 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.
TIP You can open the macro security settings dialog box from the Developer tab in the Ribbon, which is part of the Microsoft Office Fluent user interface. If theDeveloper tab is not available, click the Microsoft Office Button
, and then click Excel Options. Click Popular, and then select the Show Developer tab in the Ribbon check box.

How can the Trust Center help protect me from unsafe macros?
Before enabling a macro in a document, the Trust Center checks for the following information:
- The macro is signed by the developer with a digital signature.
- The digital signature is valid.
- This digital signature is current (not expired).
- The certificate associated with the digital signature was issued by a reputable certificate authority (CA).
- The developer who signed the macro is a trusted publisher.
If the Trust Center detects a problem with any of these, the macro is disabled by default, and the Message Bar appears to notify you of a potentially unsafe macro.

To enable the macro click Options on the Message Bar, a security dialog box opens. See the next section for information about making decisions about macros and security.
NOTE In Microsoft Office Outlook 2007 and Microsoft Office Publisher 2007, security alerts appear in dialog boxes, not in the Message Bar.
