The Notes section of Outlook has the “deprecated” status. The envisioned replacement for this Outlook feature is OneNote.
This is a great alternative but unfortunately, there is no convenient way to get all your Outlook Notes into OneNote.
While you could print all your Outlook Notes to OneNote, they will end up as images and you’ll have to rely on OneNote’s text recognition to search through them or to convert them back to text-based notes.
This guide offers an alternative solution to quickly get all your Outlook Notes into OneNote via the email@example.com service. Each note will then be added as a single OneNote page with all the text fully intact.
