If an Office add-in violates copyright, trademark, or other intellectual property guidelines, you can report it by filling out the Content Infringement Form.
Important: New name for apps for Office - Office Add-ins. We are currently updating our products, documentation, samples, and other resources to reflect the platform name change from "apps for Office and SharePoint" to "Office and SharePoint Add-ins". We made this change to better distinguish the extension platform from Office apps (applications). While these changes are taking place, the dialogs and messages you see in your application might be different than what you see in this article
You can also report an Office add-in if it contains offensive content, malware, or child exploitation.
In the Office Store, find and open the page for the Office add-in you want to report.
At the bottom of the Overview section, click Report this add-in.
Fill out and submit the Report a violation on Applications form.
