Fix To Sync this notebook, sign in to OneNote in 5 easy steps

Whenever I opened OneNote 2016 or 2019, the error To sync this notebook, sign in to OneNote popped up. Normally I just click on the notification. Then I see the Sync icon next to the name of the notebook, and then everything works fine. Not very disturbing, but because it is mainly annoying I figured it out and described the solution below.

This worked for me. Thank you.
