Admins can now mark selected SharePoint Online sites as trusted sources, allowing content from those sites to be prioritized in Microsoft Copilot Chat and Search.
The feature, called ๐๐ฎ๐ญ๐ก๐จ๐ซ๐ข๐ญ๐๐ญ๐ข๐ฏ๐ ๐๐ข๐ญ๐๐ฌ, gives organizations a way to influence which internal content Copilot surfaces first when answering user prompts.
- A Microsoft 365 Copilot license is required to use this.
- You can configure authoritative sites using the PowerShell command:
Set-SPOSite -Identity "<site URL>" -IsAuthoritative $true
- Users will also start seeing clearer indicators like โFrom your organizationโ in results, making trusted content easier to recognize.

Thatโs an important distinction and a useful governance control as organizations begin treating AI-generated answers as part of everyday work.
