Publishing and Sharing Your Agent Across Microsoft Teams: A Complete Step-by-Step Guide
Microsoft Teams has become much more than a communication platform. It is now a central workspace where employees collaborate, manage projects, automate tasks, and interact with AI-powered assistants. With Microsoft Copilot Studio, organizations can build intelligent agents that answer questions, automate repetitive work, and improve productivity across departments. https://dellenny.com/publishing-and-sharing-your-agent-across-microsoft-teams-a-complete-step-by-step-guide/Testing and Debugging Your Microsoft 365 Agent: A Complete Guide for Building Reliable AI Assistants
Artificial intelligence is transforming the way businesses work, and Microsoft 365 Agents are leading this change. These intelligent assistants can automate repetitive tasks, answer employee questions, summarize meetings, retrieve documents, and improve collaboration across Microsoft 365 applications. However, creating an agent is only the first step. The real challenge begins when it’s time to test and debug it. https://dellenny.com/testing-and-debugging-your-microsoft-365-agent-a-complete-guide-for-building-reliable-ai-assistants/What Is Microsoft 365 Agent Builder? A Beginner’s Guide
Artificial intelligence is changing how people work, communicate, and solve problems. Over the past few years, Microsoft has introduced several AI-powered tools to make everyday business tasks easier and more efficient. One of the newest additions to this growing ecosystem is Microsoft 365 Agent Builder, a feature designed to help users create intelligent AI agents without requiring advanced programming skills. https://dellenny.com/what-is-microsoft-365-agent-builder-a-beginners-guide/The Sadly Unfulfilled Promise of the Outlook Calendar Agent
The Outlook calendar agent seemed to be the answer to the difficulties that I sometimes encounter when trying to sort out my schedule. Alas, the agent failed to deliver when it was given guidelines about how I wanted to create appointments. The overall experience makes me consider whether the huge investment Microsoft is making to infuse AI into its products sometimes turns out duds. Like an agent that can’t schedule. https://office365itpros.com/2026/07/07/calendar-agent-disappoints/Two Microsoft 365 Copilot Changes That Just Make Sense
Two recent changes to the Microsoft 365 Copilot Chat app have made the app easier to use. Interaction persistence is better, meaning that chat threads are always created and available to go back to if necessary, and Copilot memory is managed more easily. Copilot memory is an intensely personal capability. If you spend the time to figure out the instructions that Copilot should always remember, the quality of Copilot responses will be much better. https://office365itpros.com/2026/06/29/copilot-memory-updates/Introducing Microsoft Copilot Cowork
For the last couple of years, generative AI has mostly acted like an eager, highly capable research assistant. You give it a prompt, it spits out an email draft, a summary, or a bit of code, and then it waits for you to tell it what to do next. It’s useful, but the operational drag of constantly guiding it step-by-step still falls squarely on your shoulders. That dynamic is officially changing. With the general availability of Microsoft Copilot Cowork, Microsoft is shifting AI from a passive conversational tool into an autonomous execution agent. Instead of prompting an AI to help you build a deck, you can now delegate entire multi-step workflows to Cowork, let it run in the cloud background, and simply review its work at key checkpoints. Here is a breakdown of what Cowork is, how it functions, and why it changes standard team workflows. What is Microsoft Cowork? At its core, Cowork is an automation and execution layer built directly into Microsoft 365. Rather than responding to single prompts, Cowork translates a high-level intent into a multi step project plan, coordinates across multiple M365 apps simultaneously, and delivers a completed result. The technology behind it stems from Microsoft’s partnership with Anthropic, effectively integrating cloud based agentic workflows under your organization's existing enterprise security, compliance, and identity controls. Driven by an organizational context engine called Work IQ, Cowork doesn't just look at a single file, it synthesizes signals across your Outlook emails, Teams chats, SharePoint documents, and calendars to understand how your team operates. How It Works: From Intent to Action Using Cowork feels fundamentally different from standard prompting. You can input an outcome request using natural language (up to 16,000 characters) and attach relevant background files. The Execution Process Deconstructs the Goal: Cowork breaks your request down into an operational roadmap. Background Execution: The agent executes the plan in a protected cloud sandbox. You can close your laptop or switch devices, and the task keeps running. Human-in-the-Loop Approvals: For medium-to-high-risk actions—like firing off a client email or posting a final update to a public Teams channel Cowork pauses and explicitly asks for your permission via a risk level indicator card. The Power of Reusable "Skills" What makes Cowork a true team framework is its underlying Skills architecture. Out of the box, Cowork ships with 13 built-in skills spanning core workplace needs: Skill Group Core Capabilities Content & Files Create and edit Word documents, Excel sheets, PowerPoint presentations, and PDFs. Organization Automated calendar optimization, meeting intelligence, scheduling, and custom daily briefings. Communication Multi-app drafting across Email, Teams channels, and structured Adaptive Cards. Analysis Deep Research capabilities that aggregate broadly across multiple corporate sources. Building Custom Workflows Beyond the defaults, teams can create up to 20 custom skills by simply dropping a formatted markdown file (SKILL.md) into a designated OneDrive folder. Instead of every employee reinventing how they handle a project handover, a weekly status update, or client onboarding, the team can standardize a repeatable workflow. For example, a custom "Weekly Reporting" skill can instruct Cowork to scan team updates, flag blockers, cross-reference an Excel sheet, and format a client-ready summary automatically every Friday morning. Managing the Sandbox: Cost and Controls Because Cowork handles complex, long-running tasks that call multiple models, its runtime is consumption-based rather than a flat monthly fee, tracking via Copilot Credits. Tasks are categorized based on their complexity: Light/Medium Tasks: Applying structured reasoning across a few local sources to generate dual outputs. Heavy Tasks: Deep reasoning that aggregates data across a massive corporate ecosystem and outputs multiple complex documents. To prevent budget overruns, IT administrators have granular control over the ecosystem. Admins can set tenant, group, and user-level spending limits, and users can request additional credits directly from the Cowork interface when tackling particularly heavy computational tasks. Sum up Microsoft Cowork marks a distinct evolution in workplace productivity. The value isn't just about writing a single email faster; it's about reducing the daily operational chaos by automating the manual coordination that slows teams down. By handing off predictable rules-based workflows to an autonomous digital teammate, professionals can shift their energy away from administrative legwork and focus it back onto strategic decision-making.From Draft to Decision: How to Integrate Copilot Studio Agents with Power Automate
Artificial intelligence is changing the way businesses communicate. Today, AI assistants can understand requests, generate content, summarize information, and help employees complete tasks faster.

Playing in the Sandbox (apparently)
Greetings all, I am trying to figure out how to fix my 365 Copilot repeatedly delivering me sandbox links instead of actual file downloads. I have already: 1. Logged out and back in. 2. Closed and opened 3. Gone into system settings, terminated, repair, and reloaded 4. Exhausted all solutions the Chat person/bot was able to tell. I am using the 365 Copilot app on a Windows 11 Laptop. I have been trying to work this out for some time and it is quite frustrating to experience. I have spent hours searching on my own and on with chat. And to think... I PAY for this product... Anyway, rant over. Can someone help to guide me to the solution? Below is the Chat I had with a Microsoft Agent. The more useful context is lower down. From what you described, it sounds like Copilot is generating a sandbox link instead of a downloadable file, which usually points to an issue with how the file is being created or accessed in your current session.

Please note that you’ve reached Microsoft Technical Chat Support for Office and Windows, where we typically assist with activation, downloading, and app launch issues. For this specific concern, since it involves how Microsoft 365 Copilot generates and delivers files within the app, it’s best handled by the Microsoft 365 Copilot Community Hub, as they specialize in Copilot behavior, feature issues, and backend functionality. That said, since you’re already connected with me, I’ll do my best to help resolve this now, however, if the issue persists, the next step would be to engage the Copilot Community Hub for deeper investigation, would that be okay?

Spent hours trying to build an employee feedback workflow with Power Automate
Someone on our leadership team asked if we could set up a system where employees can give each other continuous feedback through Teams. I spent the last two days trying to build this with Power Automate + Forms + SharePoint and honestly its a mess. The form submissions dont tie back to employee profiles cleanly, theres no good way to aggregate feedback per person over time. Is there a more elegant way to handle continuous feedback within the M365 stack?Copilot and DLP policy behaviours
Hi Copilot Brain Trust, Looking for some real-world experiences with Microsoft 365 Copilot DLP enforcement. We've implemented a DLP policy targeting the Microsoft 365 Copilot location with the action to prevent Copilot from processing content that contains our sensitivity label (restricted). The implementation is based on the following Microsoft documentation: DLP for Microsoft 365 Copilot: https://learn.microsoft.com/en-us/purview/dlp-microsoft365-copilot-location-learn-about Create DLP policies for Microsoft 365 Copilot: https://learn.microsoft.com/en-us/purview/dlp-microsoft365-copilot Microsoft documentation states that when a DLP policy blocks Copilot processing, protected content should not be processed or used in Copilot-generated responses (although citations may still appear). However, during testing we're observing scenarios where Copilot appears to access/process provide restricted snippet with file names from content that should be protected by the DLP policy. A few questions for anyone who has implemented this in production: Have you successfully validated DLP policies preventing Copilot from summarising sensitivity-labelled content? Are there any known delays between policy deployment and enforcement? Have you observed differences between Copilot Chat and Copilot experiences within Word, Excel, or PowerPoint? Are there any prerequisites, limitations, or known issues not currently reflected in the public documentation? I'm interested to hear whether others have seen similar behaviour or have successfully validated this scenario end-to-end. Thanks in advance.Best Practices for Copilot Studio Environment Strategy and Application Lifecycle Management (ALM)
As organizations increasingly adopt Microsoft Copilot Studio to build intelligent copilots, virtual assistants, and AI-powered business solutions, establishing a robust environment strategy and Application Lifecycle Management (ALM) framework becomes critical. While creating copilots is relatively straightforward, managing them across development, testing, and production environments requires careful planning to ensure scalability, security, governance, and operational excellence. https://dellenny.com/best-practices-for-copilot-studio-environment-strategy-and-application-lifecycle-management-alm/Learning Agent by Microsoft: The Future of Personalized AI-Powered Employee Upskilling Has Arrived
