I’ve been watching Microsoft roll out a lot of Copilot changes this year, and this one’s got me genuinely excited. From mid-September, Microsoft 365 Copilot starts using your chat history to personalise its answers. Not just the things you’ve told it to remember on purpose, but patterns and details picked up from your everyday conversations with it.
For a lot of businesses, this is the kind of update that quietly makes everyone’s day a bit easier. Copilot starts feeling less like a tool you have to re-explain yourself to every time, and more like a colleague who actually remembers how you like to work.
What’s Actually Changing
Up until now, Copilot Memory has mostly worked on things you’ve deliberately told it to remember. Things like “I prefer bullet points” or “I’m working on the Meridian project.” You’d see a little “memory updated” note, and that was that.
The update takes this further.
Copilot will start drawing on your broader chat history to personalise responses, even without you asking it to remember anything specific. Microsoft describes this as helping Copilot “learn as it goes,” discarding older details when they’re no longer useful and picking up new context as your conversations shift.
There’s also a redesigned Memory settings page coming with it, giving you clearer visibility into what Copilot has picked up and easy control over managing it.
That’s a nice touch, because it means you get the benefit of a smarter assistant without losing sight of what’s shaping its answers.
Why This Is a Genuinely Good Update
Think about how much time gets lost re-explaining context to a tool. You ask Copilot to draft something, and you end up repeating the same background details you gave it last week, and the week before that.
A memory that actually carries forward means less repetition and faster, more relevant help every time you open a chat.
Microsoft’s been working towards one seamless experience, which we touched on when Copilot moved to a single unified app. Memory is really the next piece of that puzzle.
It’s what turns Copilot from a tool you use into an assistant that actually gets to know how your business operates.
For teams already putting effort into their AI setup, this is one of those changes that rewards the work you’ve already done.
If you’ve been building out a solid knowledge layer, which we’ve talked about as the thing that actually drives value from AI, memory adds another layer of context that makes Copilot sharper still.
Who Gets the Most Out of It
Some teams are going to notice the difference straight away:
- People who use Copilot daily for drafting, summarising or research, since less repeated context means faster results
- Teams working on long-running projects, where Copilot can build a clearer picture over time instead of starting fresh each chat
- Anyone juggling multiple workstreams, since Copilot can pick up on the right context depending on what you’re working on
- Businesses that have already invested in tidying up their knowledge layer, since memory adds to work already done rather than replacing it
If you’re not sure where your team fits, it’s worth a quick look either way.
The best part about this update is that Microsoft’s given everyone clear visibility and control, so you get to shape it around how your business actually works.
Making the Most of It
A good update deserves a bit of setup to get the most out of it. Here’s what’s worth doing as it rolls out:
- Open Copilot’s Memory settings and see what it’s already picked up, it’s a nice way to see the update in action
- Think about which teams would benefit most from richer personalisation, and lean into it there first
- Chat with your IT admin about tenant-wide settings, so the whole business gets the benefit consistently
- Keep an eye on the rollout timeline, since Microsoft’s already refined it once to make sure it lands well
None of this takes long, and it’s the kind of small step that pays off every time someone opens a Copilot chat afterwards.
A Step in the Right Direction
Updates like this are a good reminder that Copilot’s only getting more useful the longer you’re with it. Memory is one of those features that rewards patience, since the more you use it, the better it gets at helping you specifically.
If you’re already thinking about your Copilot setup or want to make sure your team’s set up to get the most from this, that’s exactly the kind of thing we love helping businesses with.
