Copilot Cowork Is Now Generally Available: Assign Complex Multi-Tool Work to Copilot and Get a Completed Result Back

What You'll Learn

• What Copilot Cowork is and how it differs from standard Copilot chat
• Which enterprise compliance features are available at GA (audit logs, DLP, sensitivity labels)
• The models powering Cowork at launch: Opus 4.8, Sonnet 4.6, and GPT 5.5
• Which partner plugins are live now (S&P Global, Monday.com, Miro, Harvey, and more)
• Three high-value workflows to run in your first week

Microsoft shipped Copilot Cowork to general availability this week, making it available to all Microsoft 365 Copilot tenants. The core distinction from standard Copilot: you hand Cowork a complex task that spans multiple tools and data sources, and it runs the full workflow end-to-end. You get a completed result, not a draft or a suggested next step.

The difference matters. Standard Copilot answers questions and drafts content inside individual apps. Cowork executes work. The example Microsoft uses internally: "Pull last quarter's sales data, compare it to the same period last year, flag the three biggest variances, and draft an executive summary." In standard Copilot, that is four separate prompts across three apps. In Cowork, it is one task.

Cowork is not free. It runs on Copilot Credits (usage-based billing) on top of your existing M365 Copilot license. But the GA launch includes full enterprise compliance coverage from day one, which is the reason most large organizations held off during preview.

What Cowork Adds That Standard Copilot Does Not

Standard Microsoft 365 Copilot is optimized for single-app interactions: drafting in Word, analyzing in Excel, summarizing in Outlook. It does this well. But any task that requires crossing app boundaries, like pulling a Teams transcript and using it to update a SharePoint project status and draft a stakeholder email, requires manual handoffs between Copilot sessions.

Cowork eliminates those handoffs. You define the work in plain language. Cowork breaks it into steps, executes each step using the tools and data it has access to (within your organization's Microsoft 365 trust boundary), and returns the completed output. The full task log is available in the audit console so you can see what Cowork read, what it wrote, and what decisions it made.

Compliance at GA: What's Live Now

The GA release ships with the following enterprise compliance features, all active by default:

• Audit logs. Every Cowork task generates a log: what was accessed, what was produced, who initiated the task. Accessible via the Microsoft Purview compliance portal.
• Data Security Posture Management and eDiscovery. Cowork respects your organization's existing DLP policies. It will not write to or read from locations that violate your configured policies.
• Insider Risk Management. Unusual access patterns flagged by your IRM policies apply to Cowork tasks, the same way they apply to human user activity.
• Sensitivity label inheritance. Documents produced by Cowork inherit the sensitivity labels of the source data it used. A document built from Confidential source files gets a Confidential label automatically.

Data Loss Prevention support is on the roadmap and not yet live at GA. If DLP is a hard requirement for your organization, factor that in before full deployment.

Models Running Cowork at Launch

Cowork runs on Anthropic's Opus 4.8 and Sonnet 4.6 at GA, with GPT 5.5 available through Microsoft's Frontier tier. Microsoft has confirmed a Cowork 1 model (purpose-built for long-running task execution) in development and expected in the coming weeks.

This is one of the first enterprise products to make the model selection explicit: you are choosing between frontier reasoning (Opus 4.8 for complex, multi-step analysis) and faster throughput (Sonnet 4.6 for high-volume task processing). The credits consumed differ accordingly.

Three Workflows to Start With

1. Weekly Business Review Package

Define the task once: pull sales data from Dynamics, pull project status from Planner, pull customer ticket counts from the support queue, compare to last week, and draft a one-page executive summary. Schedule it to run every Friday afternoon. Walk into Monday with the brief already written.

Cowork task: Pull this week's sales pipeline from Dynamics (deals moved to Proposal or Closed Won), summarize open project milestones from Planner with any items overdue, and combine with a one-paragraph note on the top 3 customer support themes from last week's tickets. Format as a single-page executive brief titled "Weekly Business Review - [DATE]" and save to the Exec Briefings SharePoint folder.

2. Competitive Intelligence Update

Use Cowork with the S&P Global or Morningstar plugin (both live at GA) to pull competitor earnings data, combine it with web research, and produce a formatted competitive landscape update in your SharePoint library once a month. This replaces 3 to 4 hours of manual research per cycle.

3. Contract Review and Summary

With Harvey (a legal-focused AI platform) available as a GA partner plugin, Cowork can process contracts at scale: extract key terms, flag deviations from your standard templates, and produce a risk summary in a format your legal team already uses. If your contracts live in SharePoint, this is now a one-prompt workflow.

Action Steps

• Confirm your M365 Copilot license status. Cowork requires a Microsoft 365 Copilot license. If your org has the license, Cowork is available now at no additional fixed cost (usage billed via Copilot Credits).
• Review the compliance settings with your IT admin. Audit logs and sensitivity labels are on by default, but review the DLP gap (not yet live) before processing highly sensitive data.
• Pick one recurring weekly workflow. The Weekly Business Review Package is the highest ROI starting point. Map out what data sources it would need to touch and confirm Cowork has access.
• Check the partner plugin list. The GA launch includes 10 partner plugins. If your organization uses Monday.com, Miro, or S&P Global, those are ready now. Adobe, Atlassian, and Box are listed as "coming soon."
