On 14 October 2025, Microsoft will retire the OneNote for Windows 10 app.
From this date you will NOT be able to use the OneNote for Windows 10 app and you must use the OneNote app included with Office 365 installs, or downloaded direct from Microsoft via https://www.onenote.com/Download
Why is this happening?
Enhanced Security – the desktop app for OneNote supports a number of improved security functions including the ability to use sensitivity labels. Whilst this is not currently in use in Imperial, it might be utilised in the future.
New Features and AI power – The OneNote desktop app has a development cycle which will continue Microsoft’s investment in feature and AI development.
Improved Performance and Support – the OneNote for Windows 10 app no longer receives security or feature updates. This can lead to potential performance and security issues. As such we strongly recommend that you update to using the OneNote desktop app and cease using the OneNote for Windows 10 app AS SOON AS POSSIBLE.
Faster Sync and Collaboration – From June 2025, Microsoft have announced that the OneNote for Windows 10 app will have much slower sync and collaboration capabilities when compared with the OneNote desktop app.
Uninterrupted Experience – Users of the OneNote for Windows 10 app will, from July 2025, see banner notifications about the forthcoming retirement. These notifications may interrupt your workflows, so plan ahead and make the move to OneNote desktop NOW.
How do I move to the OneNote desktop app?
Ensure that you have the app installed. Follow the download link (https://www.onenote.com/Download) or go to the Start button, click to see all apps and look for OneNote and NOT the “OneNote for Windows 10” in the start menu.
Open your notebook online from https://portal.office.com (log in with your username@ic.ac.uk). The choose to edit in OneNote and when prompted open the OneNote app and note the one for Windows 10.
