Identifying custom buttons and controls added to the Ribbon from add-ins

Add-ins and documents can add custom buttons and controls to the Ribbon, which is part of the Microsoft Office Fluent user interface. All custom controls in the Office Fluent Ribbon have a special ScreenTip that identifies the origin of the control. In this example, the control comes from RXDemo.xlsm, and is identified in the control's ScreenTip.
Ribbon image
This way, you know where the custom controls are coming from and can then remove or update the document, global template, or COM add-in that is presenting the control. See the previous section to learn how to view installed COM add-ins.

How can the Trust Center help to protect me from unsafe add-ins?

By default, installed and registered add-ins are allowed to run without notification. Add-ins can be exploited by hackers to do malicious harm, such as spreading a virus, so you can use the security settings for add-ins to change this behavior. For more information, see View or change the add-in security settings later in this article.
If you or your administrator set a higher security setting for add-ins and the Trust Center detects a potentially unsafe add-in that does not meet these criteria, the Trust Center disables the code by default, and the Message Bar appears to notify you of a potentially unsafe add-in or application extension.
Message Bar
If you click Options on the Message Bar, a security dialog box opens, giving you the option to enable the add-in. See the next section for how to make a secure decision before you click an option.
 Note   In Microsoft Office Outlook 2007 and Microsoft Office Publisher 2007, security alerts appear in dialog boxes, not in the Message Bar. By default, Office Outlook 2007 allows any installed add-in to run. To change the default setting, see View or change the add-in security settings.

What should I do when a security warning asks if I want to enable or disable an add-in or application extension?

When a security dialog box appears, you can enable the add-in for just the current session by clicking Enable this add-in for this session only, or you can leave it disabled. You should enable the add-in only if you are sure it is from a trustworthy source.
Microsoft Office Security Options dialog box
Alternately, you can explicitly trust the publisher by clicking Enable all code published by this publisher. Doing so enables the add-in and allows any software by that publisher to be always trusted.

Microsoft Office Outlook

In Office Outlook 2007, when the security dialog box appears, you can enable the add-in for just the current session by clicking Enable Application Add-in, or you can leave it disabled. You should enable the add-in only if you are sure it is from a trustworthy source.
Microsoft Office Outlook Security Notice
Alternately, you can explicitly trust the publisher by clicking Trust all documents from this publisher. Doing so enables the add-in and allows any software by that publisher to be always trusted.
For more information about trusted publishers, see Add, remove, or view a trusted publisher.
