M365 Copilot Work IQ APIs are now GA

Microsoft announced that the M365 Copilot Work IQ APIs will become generally available in June 2026. These APIs make it possible for agents built on any platform to access Work IQ and integrate it into their own solutions.

What are the APIs?

1. They improve result quality by going beyond simple prompt-and-response interactions.  Work IQ uses the semantic index with ultra-low latency, personal memory, organizational skills, structured schema, and business-specific knowledge tuning.
2. They are optimized for agent speed, reducing the number of required round trips.
3. They are efficient APIs that reduce the number of tokens needed to retrieve context.
4. They are designed to support agent-scale usage, including continuous, high-frequency, multi-step operations that require high throughput.
5. They operate within Microsoft 365’s security and governance model, helping developers ensure returned data respects customer controls and policies.

The Result?

As a result, developers can safely bring Microsoft 365 data and context into their agents. This goes beyond a basic connector: it is an intelligent, optimized, and secure AI-scale solution that extends the value of M365 Copilot Work IQ to line-of-business agents, regardless of the platform they are built on.

Pricing

To use the Work IQ APIs:

• Customers must have M365 Copilot Credits, which can be purchased in bundles or consumed on a usage basis. They can also use cost management dashboards and policies to monitor and manage credit usage.
• Users also need an active M365 Copilot license, which must be maintained to access Work IQ.

M365 Copilot Cowork is GA

One of this week’s major announcements is that Copilot Cowork, previously in preview for the past few months as a Frontier capability, is now generally available for all tenants.

What is Copilot Cowork

If you are not familiar with Copilot Cowork, it moves users beyond simple prompts and responses by enabling them to delegate long-running, multi-step work that progresses over time. It uses Microsoft Work IQ to understand organizational context across email, meetings, chats, files, and other sources, then creates a plan, reasons across tools, and executes tasks with visible progress. Users remain in control and can review, pause, stop, or redirect actions at any point. Unlike traditional chat-based AI, Cowork is designed for agentic execution, allowing Copilot to coordinate work across multiple applications. Cowork also supports a multi-model design, enabling the best model to be used for the work at hand. Today, Copilot Cowork can leverage Opus 4.8, Sonnet 4.6, and GPT 5.5, with Cowork 1 coming soon.

One important point to note is that Cowork has a different pricing model. Customers must first have a Microsoft 365 Copilot license, and Cowork usage is then billed based on the tasks users run. In other words, Cowork can add costs beyond the per-user monthly Microsoft 365 Copilot license. Billing is usage-based, denominated in Copilot Credits, and task pricing is calculated from four inputs: model use, context retrieval, tool calls, and runtime.

If that seems a little confusing, here are some good examples of how to put that in context.  Below are three of the most common patterns that have been observed.

Copilot Cowork Pricing

Customers can use built-in controls to manage Copilot Credit usage. They can define who has access to Cowork, set spending limits at the tenant, group, or user level, and allocate more credits to users who are expected to use Cowork heavily. Cowork is off by default, and administrators can configure usage alerts, approve requests for additional credits, and use reporting to monitor consumption and adjust policies over time.

There are two payment options for Copilot Credits. Pay-as-you-go pricing is $0.01 per Copilot Credit, while P3 lets customers purchase credits in volume at a discounted rate.

Microsoft 365 Backup Granular Restore

Microsoft 365 Backup has released a new capability called Granular Restore.  M365 Backup has allowed administrators to recover OneDrive accounts and SharePoint Sites.  Up till now, administrators had to restore the entire account or site to get access to specific files of interest.  Now with Granular Restore, admins can perform targeted recovery of specific files by browsing or searching snapshots, selecting specific files or folders, and restoring only what is needed.

New M365 Copilot Critique and Council features

M365 Copilot Researcher agent is adding new capabilities for deep, complex research. There are two new features: Critique and Council.

Critique is a multi-model research workflow that lets you use different models including to research.  This allows you to use both Anthropic and OpenAI to generate and improve an answer.  For instance, one model plans the work, retrieves information, and drafts the response; a second model reviews and refines the draft to produce the final output. Then the second model focuses on review and refinement, acting as an expert reviewer of the final research response. 

Council is designed for side-by-side model comparisons. Council is different approach and is designed for side-by-side comparison across multiple models.  In this case, Councill will run both Anthropic and OpenAI in parallel and will present a report shown at the end as a comparison between both models.  Once this is completed, a dedicated judge model evaluates both reports and then uses a judge model to synthesize the key findings.

New M365 Copilot DLP Capabilities

Microsoft 365 Copilot now includes new data loss prevention (DLP) capabilities customers should be aware of. Until now, I have typically recommended using SharePoint Advanced Management (SAM) to reduce oversharing and Sensitivity Labels to prevent Copilot from processing sensitive documents even when users have access. There are some new M365 Copilot DLP capabilities that customers should know about.  Today, there are some really good things customers can figure with M365 Copilot to protect against data loss.  Up to now, I have usually talked with customers about implementing SharePoint Advanced Management (SAM) to restrict oversharing of data plus I have recommended implementing Sensitivity Label policies to restrict sensitive documents from being processed by M365 Copilot (even if the user has legitimate access to the data).

A new preview feature lets you apply DLP policies to Copilot prompts themselves, blocking prompts that contain configured sensitive information types. This real-There is a new feature that is in preview that enables you to create DLP policy to protect sensitive information types from even being submitted in M365 Copilot Prompts.  This real time control helps reduce data leakage and oversharing. You can also   Users would not be allowed to even allow prompts to continue if there is sensitive information present.  You can also create policy that would allow users to work with sensitive content but restrict where the prompt can be sent for example, limiting it to internal processing only.
