Why Microsoft 365 Copilot Works for Some and Not for Others
I Can’t Wait for Agentic Experiences to Make Copilot Useful
We’re all on a journey to understand how to use artificial intelligence effectively to improve systems, lives, and human existence. If you pay for the necessary licenses, Copilot is everywhere within the Microsoft 365 ecosystem, both as helpers deployed in desktop apps like Word, Teams, and PowerPoint, and the possibility of custom agents for tenants to develop and deploy, albeit without the necessary tools to manage potentially thousands of agents created by citizen developers.
According to Microsoft CEO Satya Nadella, Microsoft wants to make it as simple for people to create agents than it is to create an Excel worksheet, which might mean the creation of the “highly customized agentic experiences” referred to in Microsoft 365 center notification MC985480 (January 22). I don’t quite know that phrase means, and the clarifying text that said it “means you can design unique prompts, connect to any LLM, and integrate these custom agents with Microsoft 365 Copilot” wasn’t much help either. When I asked Copilot, it struggled with the concept too (Figure 1). In any case, I’m sure that we’ll all be happy in our highly customized agentic world when it arrives.

Why Today’s AI Falls Short of its Hype
All of which brings me to a thoughtful article in the Tomorrow’s Blueprint blog entitled “Why Others Think AI Is a Miracle But You Think It’s Useless.” The author is Microsoft product manager Abram Jackson, now deeply involved in the development of Microsoft 365 Copilot. The core of the article is an assertion that:
“Today’s AI falls short of its hype for many due to three big reasons:
- It often doesn’t have the data it needs to work with
- Defining tasks precisely is very difficult
- There’s little AI can do other than give you text or images.”
Abram knows much more about AI than I do. I reckon that he has captured the problems faced by many organizations as they consider how to extract value from a potentially massive investment in Copilot licenses.
Without access to data, Copilot can do nothing. The magic of Microsoft 365 Copilot, if some exists, is the Microsoft Graph, or access to the documents, emails, and Teams messages stored within Microsoft 365. Yet the legacy of some older Microsoft decisions around collaboration strategy forced organizations to restrict SharePoint Search to stop Copilot revealing information to anyone who asked. As it turns out, it is hard to stop Copilot using data because even document metadata can reveal secrets.
I like the way Abram discusses the issue of defining tasks. Math works because the answer is either right or wrong. Copilot works very well when given well-defined tasks to do, like summarizing a meeting transcript or extracting tasks for people to consider. The same goes for scanning an email thread or summarizing a Word document. Generating text is less satisfactory unless the user is very precise in their prompt and grounds Copilot with some suitable input, like documents to work from. The promise of early demos where Copilot generated project reports and other material in the blink of an eye is never attained where loose prompting gives the AI free rein to indulge itself.
How People Need to Use AI
The summary is that to extract value from AI (and Microsoft 365 Copilot in particular), users must:
Understand if a task is valuable and not prone to hallucinations. Asking Copilot for Word to scan a document and decide if it is well-structured and how make improvements is valuable for many people who aren’t natural writers. Asking Copilot for Word to generate the initial document introduces the possibility of hallucinations.
Work to define the task precisely: Asking Copilot to do something very precisely with clear boundaries and guidelines will generate much better results than dashing off a quick prompt.
Translate the result generated by the AI into the form you need it to be. For chat, the introduction of Copilot pages has proven useful because it allows users to easily capture the output generated by Copilot for reuse. But will the slides generated by Copilot for PowerPoint be the type you need? Or can Copilot for Excel really perform the computations you want? Of course, they can, but only with practice and perseverance on the part of the human.
As Abram says, this approach “isn’t natural and it is time-consuming.” It comes about because Copilot is essentially an eager assistant that wants to work but will do stupid things unless you tell it precisely what to do and how to do it. Expanding on the example shown in Figure 1, adding context and direction to the prompt gives Copilot the chance to deliver a much better answer. Prompts can now be up to 128,000 characters, so there’s lots of room for comprehensive instructions.

The Bing Conundrum
One last point about data being available for Copilot to work with. I’m not sure about Abram’s statement that “hallucination is largely a solved problem for Microsoft Copilot.” I see odd stuff generated all the time. Abram justifies his claim by saying that “Copilot is trained to only respond with information it has been able to find through search.”
Copilot depends on Bing and Bing isn’t very good at searching. Take this website. Despite the ease in which Google has indexed and searched all my articles for years, Bing stubbornly refused to touch the site. I only discovered this fact when creating some declarative agents that used office365itpros.com as a source. Since then, the best efforts of WordPress support and my own attempts to navigate the online Bing webmaster advice have only just persuaded Bing to start indexing some pages. Some of the blocks are quite silly. One problem that caused Bing to refuse to index pages was the lack of an alt tag for a graphic in a sidebar.
If Copilot had better search facilities, it could generate better answers because it has better data to work with.
So much change, all the time. It’s a challenge to stay abreast of all the updates Microsoft makes across the Microsoft 365 ecosystem.
