Microsoft 365 Copilot: Quick Start Guide

Key insights

• Microsoft 365 Copilot: The video presents Copilot as an AI assistant built into Microsoft 365 that helps create, summarize, analyze, and automate work inside Word, Excel, PowerPoint, Outlook and Teams.
  It requires appropriate licensing for full features (agent building, enterprise data access) and is aimed at business users and IT leaders wanting strategic adoption.
  
• Work IQ and Grounding: Copilot uses your organizational data (emails, files, Teams chats, SharePoint) to give context-aware answers while keeping enterprise security and data protection central.
  The tutorial explains the difference between the Work mode (your company data) and the Web mode (broader internet research) and how each affects results and trustworthiness.
  
• GCSE prompt framework: The instructor recommends a structured prompt style (clear goal, context, constraints and examples) to get reliable, concise outputs from Copilot.
  The video also covers refining prompts, saving them to a gallery, and scheduling recurring prompts to automate routine tasks.
  
• Pages and Notebooks: Use Pages to copy and collaborate on Copilot-generated content and Notebooks to organize ongoing work and research in a shared space.
  These features help teams track iterations, keep sources grounded, and maintain a single place for task handoffs and notes.
  
• Agents and Agent Store: You can build no-code Copilot agents that connect to web sources or your work data for specialized tasks like research or data analysis, then share them with permission controls.
  The Agent Store offers ready-made agents (for example, Researcher and Analyst) to speed deployment and extend Copilot’s capabilities without starting from scratch.
  
• Copilot Chat vs In‑app Copilot: Copilot Chat serves as a central conversational entry point with mode switching and broad tool access, while in-app Copilot embeds AI features directly into Teams, Outlook, Word, Excel and PowerPoint for contextual actions like summarizing meetings, drafting emails, generating slides, and analyzing data.
  The tutorial highlights practical workflows and upcoming agent mode rollouts for Excel and Word to bring automation deeper into everyday apps.
  

Overview: A practical Copilot tutorial for business users

Lisa Crosbie [MVP] published a detailed YouTube tutorial that walks viewers through Microsoft 365 Copilot from basics to advanced features. The video aims to help business users, IT pros, and leaders move beyond experimentation and capture measurable value. Moreover, it balances technical guidance with everyday scenarios, showing how Copilot can assist in email triage, document creation, and data analysis. Consequently, the tutorial serves both beginners and teams planning a rollout.

How Copilot works and licensing essentials

First, Crosbie explains the architecture behind Microsoft 365 Copilot, emphasizing the role of Work IQ and grounding in securing enterprise data. She clarifies that Copilot uses two main modes: Web for open web search and Work for querying an organization’s own files and communications, and that these modes affect the source and trustworthiness of answers. In addition, the video outlines licensing differences, noting that some advanced capabilities, such as building agents that access work data, require paid plans. Therefore, organizations must weigh cost against the value of automation and data-aware assistance.

Writing effective prompts with the GCSE framework

Crosbie introduces the GCSE framework to help users craft clear, repeatable prompts that produce reliable outputs. She advises combining context, desired layout, expected tone, and reference points so Copilot can generate usable drafts and summaries on the first try. Furthermore, the tutorial shows how to save, schedule, and refine prompts, which helps teams standardize outputs and reduce variation. As a result, teams can scale consistent guidance, though they should still validate sensitive results manually.

Agents and new 2026 capabilities

One of the video’s major themes is the rise of agent-building tools in 2026, which let users create custom assistants without writing code through the Agent Builder. Crosbie demonstrates how to connect agents to SharePoint, OneDrive, and selected websites so they can perform research, extract insights, or generate documents automatically. She also highlights out-of-the-box agents such as Researcher and Analyst, showing practical workflows for both web-based research and data-heavy analysis. However, she flags tradeoffs: while agents speed routine work, they increase the need for governance, access controls, and ongoing monitoring to avoid stale or incorrect outputs.

Using Copilot across apps: Teams, Outlook, Word, Excel, PowerPoint

The tutorial walks through how Copilot functions inside core apps, demonstrating different interaction styles and outcomes in Teams, Outlook, Word, Excel, and PowerPoint. For example, inside Outlook Copilot can summarize threads and draft responses, while in Excel it can generate formulas and analyze trends from tables. In PowerPoint and Word, Copilot accelerates creation and editing, but Crosbie stresses that human review remains essential for accuracy and alignment with brand voice. Thus, organizations must balance the speed gains with quality control and role-based review processes.

Practical tradeoffs and adoption challenges

Crosbie does not shy away from the challenges of adoption, such as managing licensing costs, ensuring enterprise security, and reducing hallucinations through careful grounding of prompts. She also discusses the balance between enabling broad user access for productivity gains and restricting capabilities to reduce risk, recommending staged rollouts and clear policies. Moreover, the ease of building agents brings governance challenges, since a misconfigured agent could access sensitive content or return misleading results. Therefore, IT and business leaders must coordinate on permissions, monitoring, and training.

Collaboration features and workflow recommendations

The video showcases collaboration features like Pages and Notebooks for shared work and explains how scheduled prompts and saved templates can create repeatable business processes. Crosbie encourages teams to start with high-impact, low-risk scenarios—such as meeting summarization and routine reporting—before moving to more sensitive uses. Additionally, she suggests defining success metrics early, like time saved or reduction in manual edits, so stakeholders can measure value and justify further investment. Consequently, this approach aligns adoption with measurable outcomes and continuous improvement.

Conclusion: Measured experimentation with governance

Overall, Lisa Crosbie’s tutorial offers a structured roadmap to adopting Microsoft 365 Copilot with practical tips on prompting, agent building, and app-specific uses. While the technology promises substantial productivity gains, the video emphasizes the need for governance, licensing planning, and human oversight to manage risks. In summary, organizations that pair careful piloting with clear policies and training can unlock value more safely and sustainably.
