| (Updated) Viva Engage: Agents in Viva Engage communities Public PreviewCategory:Microsoft Viva
Microsoft Copilot (Microsoft 365)Nummer:MC1155311Status:planForChange | Updated January 26, 2026: We have updated the content Thank you for your patience. [Introduction]
Agent in Viva Engage communities are now available in Public Preview. Community admins can add agents to communities to help draft answers to questions without best or verified answers based on community content and add context to posts by answering follow up questions using the community’s conversations and SharePoint site and library.
We’re now adding the option for community admins to specify 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 view (Read). We are also adding a new capability: tagging by community members. Tagging by community members enables 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 be disabled by community admins in the agent settings. [When this will happen:]
- Agents in communities Public Preview: available now
- SharePoint Grounding on Community site and library Public Preview (Worldwide): available now
- Grounding on SharePoint sites and libraries outside the community and tagging by community members Public Preview (worldwide): Starting Feb. 16th, expected to complete by mid-March.
- General Availability (Worldwide): Begins late March 2026, expected to complete by late April 2026
[How this affects your organization:]
- Who is affected: Viva Engage community admins and members with Microsoft 365 Copilot licenses; Global and Engage admins managing Viva Engage networks
- What will happen:
- During Public Preview:
- Admins can opt their network into the preview via the Engage admin center: Engage admin center > Tenant Settings > Enable Community Agent Public Preview.
Once enabled, admins can add agents to any community they manage.Figure i. Add agent to community  The agent will proactively draft answers to unanswered questions using past conversations. By default, the agent posts answers automatically. Admins can configure whether the agent posts answers automatically or only after approval and if tagging by community members is enabled. Figure ii. Configure the agent’s capabilities and knowledge sources 
[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. Figure iii. Community admins and experts can review agent suggestions
 If tagging by community members is enabled, then community members can @-mention the agent in messages. Coming soon (General Availability): The agent will only use content that all community members can access. Admins must be owners of the SharePoint sites they wish to configure. Admins can add additional SharePoint sites to expand the agent’s grounding knowledge. The agent will be grounded by default on the community’s SharePoint site. Community members can tag the community agent in community posts. All Microsoft 365 Copilot licensed users will have access to the Community Agent by default. The Community Agent Public Preview toggle will be retired.
[What you can do to prepare:]
- If participating in preview:
- Opt your network into the preview via the Engage admin center
- Communicate this change to helpdesk staff.
- Update internal documentation that references Viva Engage Community Agent behavior or setup.
- No action is required at GA; the feature will be on by default.

| Microsoft 365 Copilot: Customize Copilot for your organization with Copilot Tuning – public previewCategory:Microsoft Copilot (Microsoft 365)Nummer:MC1222551Status:stayInformed | [Introduction] Microsoft 365 Copilot Tuning is introducing new templates in Agent Builder designed for tasks such as drafting complex documents, validating documents against organizational guidelines, and editing to match a distinct writing style. Users with Copilot Tuning enabled can further customize the template-based agents by tuning the context, tools, and underlying models with their organization’s proprietary data, processes, and standards. This empowers your teams with customized agents aligned to how your organization works. [When this will happen] Public preview (Worldwide): We will begin rolling out in mid‑February 2026 and expect to complete by late March 2026. [How this affects your organization] Who is affected: - All Microsoft 365 tenants with Microsoft 365 Copilot licenses.
- Agent tuning is available to organizations with 5,000 or more Microsoft 365 Copilot licenses.
What will happen: - New agent templates will become available in Agent Builder for all users licensed for Microsoft 365 Copilot.
- Users can immediately use these templates to build agents for common Microsoft 365 tasks.
- Organizations with 5,000+ Copilot licenses can tune agents by adjusting:
Data handling, privacy, and residency - Copilot Tuning creates a snapshot of user‑selected SharePoint content solely for tuning the agent.
- Snapshots are stored in a tenant‑isolated Microsoft 365 environment and are used only within the Copilot Tuning service.
- DLP policies applied to the source SharePoint content do not apply to the snapshot.
- During public preview:
- Snapshot data is retained while the tuned agent remains active.
- Snapshot data is deleted when the tuned agent is deleted.
- Data used for tuning may be retained for up to two years unless deleted earlier.
- Copilot Tuning does not change Microsoft 365 data commitments; all data remains within the Microsoft 365 service boundary under existing Microsoft 365 Copilot privacy and security commitments.
- Snapshot metadata may be requested through Microsoft Customer Support.
- Snapshots are not automatically updated; if underlying SharePoint content changes, agents must be retrained.
Regional processing - During public preview:
- EU tenant traffic remains within the EU Data Boundary.
- Global tenant traffic may be processed in other regions for large language model operations.
- Microsoft personnel do not access customer data unless explicitly requested by the customer and approved through Customer Lockbox.
Advanced Data Residency (ADR) - Copilot Tuning is not enabled by default for tenants with ADR during public preview.
- ADR customers may opt in by formally waiving ADR requirements through their Microsoft account team.
- If waived, snapshot data is stored in the nearest macro region in a tenant‑isolated Microsoft 365 environment and governed by existing Microsoft 365 Copilot data protection commitments.
[What you can do to prepare:] No enrollment action is required; organizations are automatically enrolled. Admins can: - Manage and restrict access to Copilot Tuning in the Microsoft Admin Center by navigating to: Copilot > Settings > Copilot Tuning
- Scope tuning access to specific users or groups or disable it entirely.
- Review internal data governance, privacy, and regulatory requirements before enabling tuning.
- Communicate the new capability to internal support teams if needed.
- Update internal documentation as appropriate.

Copilot Tuning stores new snapshot copies of user‑selected SharePoint content in a tenant‑isolated Microsoft 365 environment. Snapshot data is retained while the tuned agent is active and may be retained for up to two years unless deleted earlier. | | Does the change alter how existing customer data is processed, stored, or accessed? | Yes. Copilot Tuning creates snapshot copies of SharePoint content that are not governed by DLP policies applied to the original data. Snapshots are used exclusively within the Copilot Tuning service and must be manually retrained if underlying content changes. | | Does the change introduce or significantly modify AI/ML or agent capabilities that interact with or provide access to customer data? | Yes. The feature introduces new template-based agents in Agent Builder and allows organizations to tune agent context, tools, and models using proprietary data. | | Does the change provide end users any new way of interacting with generative AI? | Yes. Users can build and customize template-based agents in Agent Builder and tune them with organizational data through Copilot Tuning. | | Does the change modify, interrupt, or disable any Purview capabilities (such as DLP, sensitivity labels, retention, or encryption)? | Yes. DLP policies applied to the source SharePoint content do not apply to the snapshot data used for tuning, which is a functional deviation administrators should be aware of. | | Does the change modify how users can access, export, delete, or correct their personal data (GDPR Data Subject Rights)? | Yes. Snapshot metadata may be requested through Microsoft Customer Support, and snapshot data is not automatically updated when underlying content changes, which may require retraining. | | Does the change include an admin control, and can it be controlled through Entra ID group membership? | Yes. Copilot Tuning can be enabled, disabled, or scoped to specific users or groups in the Microsoft admin center, including support for Entra ID group scoping. |
