SharePoint Knowledge Bases Close Copilot's Context Gap

Diesen Beitrag auf Deutsch lesen

SharePoint knowledge bases combine team knowledge with accessible content so Copilot and agents can use better grounding.

TL;DR

SharePoint knowledge bases let teams combine email, messages, meetings, and existing site content into interlinked Markdown pages that Copilot and agents can use as grounding. Any SharePoint site can host one, but team curation remains necessary because permissions and sensitivity labels control access, not whether Copilot has enough context.

This is our own summary, not a republication or full translation.

Governance takeaway

  • Makers: Add tacit team knowledge to a knowledge base because Copilot may not have the full organizational context from accessible data alone.
  • Admins/CoE: Assess how teams will create and curate knowledge bases across SharePoint sites, Teams channels, and Microsoft 365 Groups.
  • Security/Compliance: Maintain permissions and sensitivity labels because they control what Copilot may see, but do not guarantee sufficient context.
  • Leadership/Business: Evaluate usage-based billing during the Frontier preview before treating knowledge bases as a standard capability.
