Something else I noticed is that the Start Menu entry for OneNote says 'OneNote 2016', and the others don't have a year. The build number in the screenshot below is the same as the build number in Word 2019 version 1809. This may be due to minor changes that didn't exist when I updated to OneNote 2016 version 1809. Update 10-19-2018: I've reinstalled Office 2019, and the OneNote build number in Office 2019 version 1809 is larger than the build number for the stand-alone OneNote 2016 version 1809. In your Calendar, double-click to open the meeting that you want to send to OneNote. Update: I've installed OneNote from, alongside a trial of Project 2016, and this is the result: In Outlook for Mac, do the following: Open the item that you want to send to OneNote by doing either of the following: In your Inbox (or any other mailbox folder), double-click to open the email message that you want to send to OneNote. After installing Office 2019, I forgot to make a snapshot, so I can't compare the version numbers of OneNote 2019 and from the website. It's probably just OneNote 2016 with security updates and an updated 'year version'. Microsoft said that OneNote 2016 would be the last version to have a regular desktop version, but this is interesting. OneNote was still called 'OneNote 2019' even after installing the updates (to 1809) Office wanted me to install in the screenshot. Something that may be important is that I installed from Microsoft's website using the offline install media, not from the Windows/Microsoft Store app. The other day, I installed Office 2019 to see where it installs to (I work on a program that requires knowing where Office gets installed to) and was surprised to see that OneNote was included.
