Introduction

Agent in Viva Engage communities are now available in Public Preview. Community admins can add agents to communities to enhance knowledge sharing by draftinghelp draft answers to questions without best or verified answers based on community content.content and add context to posts by answering follow up questions using the community's conversations and SharePoint site and library.

Shortly after public preview begins, we'll be enhancing agents in communities with SharePoint groundingWe’re now adding the option for community admins to improve the accuracy and relevance of AI-generated answers. This update allows the agent to use content fromspecify additional SharePoint sites outside the community as grounding sources. The agent will only use sites that community admins select, and it drafts answers from items that community members can access, helping ensure responsesview (Read).

We are contextually grounded and backedalso adding a new capability: tagging by trusted sources. Agents in communities will only draft answers with content that allcommunity members. Tagging by community members have access to. Youenables Microsoft 365 copilot-licensed users to @-mention the community agent in the comments and replies of threads with follow up questions and requests to add context to posts. When tagged, the community agent will reply in the post. Tagging by community members will be enabled by default, but can set up yourbe disabled by community admins in the agent with before SharePoint grounding is available and add it later.settings.

      Grounding on SharePoint sites outside the community

      • Community admins can add SharePoint sites and libraries outside the community as additional grounding sources (for sites/libraries they administer).
      • When an admin adds a site or library, they’ll be prompted to grant the community’s Microsoft 365 group Read access if it doesn’t already have permission.
      • The agent only drafts answers using content that all community members can view (Read).
      • By default, the agent uses the community’s SharePoint site and library. Any sites outside the community are optional and add to (not replace) the default grounding.

      If Require review is enabled, admins and designated experts will be notified when the agent drafts an answer. They can approve, edit, or dismiss the response.
