In Outlook for Windows, go to File > Manage Add-ins (at the bottom of the screen.) This will open the account’s Manage Add-ins dialog. To disable it everywhere, including in Outlook on the web and in Outlook on Mac, you need to disable it in Manage Add-ins in your account online. There are new features compared to OneNote 2016, as well as removals.

However OneNote 2016 will always come on top as the suggested app, so that I manually have to scroll down to OneNote. OneNote 2021 v2103 is actually generated using OneNote v2103 in Microsoft 365 until 2021 march, repackaged, and changed the year number.

Scroll to the bottom and untick Use Send to OneNote with OneNote for Windows 10, if available. Right-click the Office application you want to remove, and then click Uninstall. Evenmore it is even weirder that I can't even remove it from the start menu. To disable the new Send to OneNote command in Outlook desktop, open File > Options > Advanced. If you use local notebooks in OneNote or use it with POP or IMAP accounts, you’ll need to disable the new OneNote function. There is also a OneNote application preloaded with Windows 10. The Office 365 Click-to-Run installer doesn't allow you to select which Office 2016 applications are installed, nor allow you to selectively remove some applications afterwards. However, because the function is tied to the mailbox you are working in, Outlook items will be sent to a notebook in that account, not to a master notebook you use with all email accounts. OneNote 2016 is included with the Office 2016 software suite.

If you use the Send to OneNote function and have the online notebook open in OneNote 2016, the page will sync down to OneNote 2016.
