Topic Last Modified: 2011-08-05
If you want to control the way add-ins behave, or prevent users from running add-ins, you can modify Microsoft Office 2010 add-in settings.
In this article:
Microsoft Office 2010 provides several settings that enable you to control the behavior of add-ins. By configuring these settings, you can do the following:
Disable add-ins on a per-application basis.
Require that add-ins are signed by a trusted publisher.
Disable notifications for unsigned add-ins.
Add-in settings can be configured only on a per-application basis. There are no global add-in settings.
For detailed information about the settings that are discussed in this article, see Security policies and settings in Office 2010. For information about how to configure security settings in the Office Customization Tool (OCT) and the Office 2010 Administrative Templates, see Configure security for Office 2010.
By default, any add-in that is installed and registered can run without user intervention or warning. Installed and registered add-ins can include the following:
Component Object Model (COM) add-ins
Visual Studio Tools for Office (VSTO) add-ins
RealTimeData (RTD) servers
Application add-ins (for example, .wll, .xll, and .xlam files)
XML expansion packs
XML style sheets
This default behavior is the same as selecting the Trust all installed add-ins and templates setting in Microsoft Office 2003 or an earlier Microsoft Office system.
