Beyond "Summarise This Email": 5 Advanced Microsoft 365 Copilot Habits of High-Performing Teams

Most UK organisations we work with rolled out Microsoft 365 Copilot somewhere in the last eighteen months, and most employees settled into the same three habits within a week:

• Summarising this email.
• Drafting a reply.
• Generating a quick first pass of this document.

While these quick wins are no doubt helpful, they only represent a fraction of what Microsoft’s AI suite can actually achieve. With the steep cost of licences, relying on basic prompts leads to massive underutilisation and poor IT budget ROI.

The teams getting genuine value out of their Microsoft 365 Copilot Business Plan have moved well past that. Here are five advanced habits we consistently see among high performers, all grounded in how Copilot operates in mid-2026.

1. Reaching for the Researcher agent instead of a quick chat prompt

There is a massive functional difference between asking Copilot Chat a quick question and handing a task to the M365 Copilot Researcher agent.

The standard chat interface is optimised for speed and short tasks, whereas Researcher is built for the kind of work that would normally eat an afternoon. This includes:

• Pulling together everything your organisation knows about a specific client or topic
• Cross-referencing it with live web data
• Delivering a beautifully structured, source-cited report.

High-performing teams can now recognise when a question is actually a deep research task. Prompts like “What is our company’s current position on X?” or “Pull together everything we know about this account” are handed to the Researcher agent. It securely scans your internal emails, OneDrive files, Teams meetings, and chats, alongside the open web. This is all while respecting your internal data boundaries, saving hours of manual sorting.

2. Scoping long-term projects inside a Microsoft Copilot Notebook

A common frustration with the standard AI chats is that they “lose the thread” over long, complex projects. High-performing teams solve this by working inside Microsoft Copilot Notebooks.

A Copilot Notebook acts as a dedicated, persistent project workspace. Instead of prompting the AI across your entire company network, you can hand-select a specific bucket of reference files, like:

• Word documents
• PowerPoint decks
• Spreadsheets
• Meeting transcriptions

You can lock these into the notebook. Copilot then answers questions and drafts content using only that defined context.

Whether you are managing a quarterly report, compiling massive client proposal, or doing competitive analysis, setting up a notebook at the start keeps your AI outputs grounded and free of hallucinations.

3. Letting Microsoft Outlook pull thread context in automatically

A small but highly impactful habit shift: rather than copying and pasting raw text out of an email thread to feed into your prompt, advanced users let Copilot pull the thread’s context automatically within Outlook.

By utilising Outlook’s native Copilot integration, you can draft complex replies that reference several previous messages or summarise a massive back-and-forth email chain before forwarding it to a colleague. It completely removes the manual effort of assembling the prompt context yourself, turning Copilot into teammate rather than an external tool.

4. Asking Microsoft Excel's Copilot to explain its logical reasoning

In Excel, Copilot can now automatically scan your wider Microsoft 365 context from related emails, meetings, and files without you having to point to them. However, the habit that separates advanced Excel users from beginners is forcing Copilot to explain its working.

Instead of simply asking Excel’s Copilot to generate a formula or edit a table, high performers ask “Show me the step-by-step logic behind this formula.” This serves two critical purposes:

1. It allows you to audit the output, catching errors before they reach a client-facing slide deck
2. It acts as an active learning tool, upskilling the employee so they understand how to manage and scale the spreadsheet long after the AI has closed

5. Treating the first prompt as a draft, not a final instruction

This is the fundamental habit that underpins all other advanced workflows. High performing teams understand that the first output from Copilot is just a baseline, not a finished product.

They treat AI like an intern. They specify their needs. If an output isn’t quite right, they don’t give up. They instruct Copilot to:

• “Make the tone more direct and commercial”
• “Highlight the financial impact in the executive summary”
• “Reorganise this timeline into a clear table”

Bridging the Copilot Adoption Gap

None of these habits require expensive licence upgrades. They're available to anyone with a Microsoft 365 Copilot seat. The reason most employees never move past the basic email summaries is simply a lack of structured exposure. They don’t know where the Researcher agent lives, what a Notebook is designed to do, or how to properly prompt Excel.

That is the exact gap structured training closes. If your organisation rolled out Copilot, but has yet to see a meaningful shift in productivity, book a Microsoft 365 Copilot training consultation with our team today and let’s unlock the true ROI of your software investment.
