remove Copilot Outlook

We see this every week in remote support sessions. Someone opens an email, spots the Copilot chat or summarise button sitting in the ribbon or reading pane, and wants it gone. The fix depends on whether you're on classic Outlook or the new client, and whether you have a Copilot licence attached to your account. This guide covers all of it, from a two-minute toggle to full admin-level removal. To remove Copilot Outlook menus properly, you need to know which version of Outlook you're running first.

What Causes the Copilot Menu to Appear in Outlook?

The short answer: Microsoft has been rolling out Copilot features across Microsoft 365 apps since 2023, and the Outlook client picks them up automatically with updates. If you're on a Microsoft 365 subscription and your build is reasonably current, the Copilot chat and summarise options will show up whether you asked for them or not. That's by design, not a bug.

There are a few specific triggers. The most common one is a Microsoft 365 Copilot licence being assigned to your account, either because your organisation bought Copilot seats or because you're on a personal Microsoft 365 plan that includes it. When the licence is active, Outlook treats Copilot as a fully enabled feature and puts it front and centre in the reading pane and ribbon.

Even without a dedicated Copilot licence, the menu can appear because connected experiences that analyse your content are turned on in Office's privacy settings. These are the same settings that power things like Editor suggestions and Smart Lookup. Copilot is technically one of these connected experiences, so if the setting is on, Copilot shows up. This catches a lot of people out because they never touched any Copilot-specific setting.

The other trigger is simply running the new Outlook for Windows client (the one that looks like Outlook on the web). That version has a dedicated Copilot toggle in its settings panel, and it defaults to on when the feature is available for your account. Classic Outlook (the traditional desktop app, sometimes called Outlook 2016/2019/365 desktop) handles it slightly differently via File > Options. Knowing which client you're on determines which fix to try first.

Worth noting: if you're in a corporate environment, your IT admin may have enabled Copilot at tenant level through the Microsoft 365 Admin Centre. In that case, local settings changes will disable the feature for you, but the icon might persist in the UI. Microsoft is transparent about this limitation in their admin control documentation for Copilot. The full removal options in that scenario require admin action.

Remove Copilot Outlook: Quick Fix (5 to 10 Minutes)

Start here. These options work for most people and don't need admin access. Try Option A if you're on classic Outlook desktop, Option B if you're on the new Outlook for Windows, and Option C if the icon is still cluttering up your ribbon after the first two.

If the quick fixes didn't stick, or if you want to make sure Copilot can't be re-enabled easily, these options go a level deeper. Option A works at the Office privacy layer and affects all Office apps. Options B and C require admin access to the Microsoft 365 Admin Centre.

One thing worth knowing before you go further: Microsoft documents Copilot as one of the 'connected experiences that analyse your content' in Office. You can read the full breakdown on the Microsoft connected experiences documentation. Disabling that category is a legitimate, supported way to stop Copilot working, and it applies across Word, Excel, and Outlook in one go.

If you're managing Outlook settings across a whole organisation, it's also worth looking at how you handle other Microsoft 365 app configurations. Our guide on managing Outlook settings in Microsoft 365 covers broader configuration options that pair well with the steps above.

Advanced Remove Copilot Outlook Fixes (30+ Minutes)

Here's the honest bit: Microsoft explicitly states there is currently no supported method to completely remove all Copilot UI elements from Microsoft 365 desktop apps when using a work or school account. The icon is baked into the app framework. What you can do is make Copilot completely non-functional and largely invisible through a combination of the methods below. For most organisations, that's good enough.

These options are for IT admins and power users. They involve registry edits, tenant-level policies, and combining multiple controls. If you're a home user, the intermediate fixes above are probably all you need. If you're managing a fleet of machines, read on.

Preventing Copilot from Coming Back in Outlook

The most important thing here is licence control. If Copilot keeps reappearing after you disable it, the most likely reason is that a Copilot licence is still assigned to the account or has been reassigned during a licence audit. Check the Microsoft 365 Admin Centre first before assuming the settings are broken.

For organisations, the priority order for prevention looks like this:

1. Licence management first. Only assign Microsoft 365 Copilot licences to accounts that genuinely need AI features. Review licence assignments every quarter. This is the single most effective control.
2. Connected experiences policy second. Push the 'disable experiences that analyse your content' setting via Office Cloud Policy or Group Policy. This acts as a backstop even if a licence accidentally gets assigned.
3. Integrated Apps block third. Block the Copilot app in Settings > Integrated Apps for user groups that should never have it. This adds another layer without requiring per-machine configuration.
4. Ribbon customisation last. Deploy a custom ribbon layout via Intune or GPO to hide the Copilot button visually. This is cosmetic but reduces confusion and support tickets.

One thing that catches IT teams out is major Office updates. Microsoft has a habit of re-enabling Copilot toggles or adding new entry points after significant client updates. Set a reminder to check Copilot settings after any major Microsoft 365 update cycle, especially the semi-annual channel releases. The Microsoft admin control page for Copilot is the best place to check for newly supported controls as they're added.

For home users on a personal Microsoft 365 subscription, the simplest prevention is keeping the Copilot toggle off in Outlook Options (classic) or Settings (new Outlook) and turning off connected experiences in Office Account privacy. Check these settings after any major Outlook update, because they have been known to reset. Annoying, but it's a two-minute check.

If you're also managing other aspects of your Microsoft 365 environment, our guide on Microsoft 365 privacy and connected experience settings covers the broader Office privacy controls in more detail.

Remove Copilot Outlook: Summary

To remove Copilot Outlook chat and summarise menus, start with the quickest option for your client version. Classic Outlook users: File > Options > Copilot > uncheck Enable Copilot. New Outlook users: Settings gear > Copilot > turn off the toggle. If the icon persists after that, hide it via Customize the Ribbon. For a more permanent fix, turn off connected experiences in Office Account privacy settings, which disables Copilot across all Office apps at once. Admins can go further by removing the Copilot licence from the user's account in the Microsoft 365 Admin Centre or blocking the Copilot integrated app for specific users or groups. And if you're managing a whole organisation, combine all four controls and enforce them via Group Policy or Intune so they survive future updates. The one thing you can't do right now is permanently delete every Copilot UI element from the desktop app. But with the right settings in place, users won't see it or be able to use it, which is the practical result most people are after.
