How do I TURN OFF the "Summary by Copilot" banner that appears on every single email I receive in outlook?

I am also looking to turn this off I would love for Microsoft to add the option to turn this of for outlook.live.com portal.

I have figured out a very, very simple workaround to kill this UI element on Chrome

1 - Install this plugin for Chrome, "Custom CSS by Denis" https://chromewebstore.google.com/detail/custom-css-by-denis/cemphncflepgmgfhcdegkbkekifodacd

2 - While you are on any outlook page (ie, outlook.office.com), click the "CSS" icon in your Extensions list to launch the CSS editor

3 - The first time you open this extension on any particular site, you will see a permissions window first - "Need permission to edit outlook.office.com" - grant those permissions

4 - Click the CSS icon again, which will now show you a text box captioned "Styles for outlook.offfice.com"

5 - Enter this text in the box and press enter

.Yd98x {display:none!important;}

6 - If you are on a message detail window, you should see the Copilot Summary box disappear instantly.

7 - If you use multiple computers - you will have to authorize permissions for the extension on each machine, separately, but - after you grant permissions - if all of your machines are logged into the same Google account - the CSS you had saved on your first machine should already be loaded back up for your on the next machine.

8 - Cautions

• This may not work forever - if Microsoft changes the class name of the Copilot block in their HTML, this code will need to be updated.
• I don't have any way of guaranteeing this is the correct class name for all users but it has been working consistently for me across a few machines today. The class name may be different on other versions of Outlook (such as personal addresses on outlook.live.com, etc.)
• I didn't author this plugin, it does seem safe in my own personal judgement, but security evaluations are up to you.

Please stop forcing copilot on me. It's not at all useful for what I'm doing, plus it wastes A LOT of my time and screen space with all the ways it's shoved in my face. Our office uses Microsoft 365 and outlook exclusively but if we don't get an option to turn off copilot and every related notification, suggestion, ad, banner, etc. we will change everything to get away from this annoyance.

Same problem and frustration. HELP.

SOLVED!!

In the Outlook app:

1. Click the settings gear in the top right of the Outlook window.
2. On the left, click on "General".
3. In the middle, click on "Privacy and data".
4. On the right, scroll all the way to the bottom and click on "Privacy settings".
5. Scroll down to "Connected experiences" and turn off "Turn on experiences that analyze your content".

The Summary by Copilot will not appear on your emails anymore.

Unfortunately, the "Privacy settings" section doesn't appear in the browser version so I don't know how to turn it off there. However, I did find this setting duplicated at https://account.microsoft.com/privacy/data-settings but it doesn't seem to work in the browser version.
