We are using Outlook for Mac version 16.34 (20011502) and OneNote for Mac version 16.34 (20011502) and we first make sure that within the OneNote for Mac is logged into work account and has the desired OneNote notebook open (on the same work account). When we try to send an email to this desired OneNote notebook it does not first show up in the side window but it does seem that after a period of time (hours) it does eventually appear in the list of available OneNote Notebooks. Our only solutions so far is to either: 1. Flag or move the Email to a Outlook folder (we named _1 OneNote to be Saved) and wait for the notebook to appear in the SendToOneNote side window or; 2. Print the email to a PDF (saving it to our Mac) and then dragging the PDF to a new OneNote page (which of course does not include any email attachments). Please help! And would love to see a search field in the Send to OneNote side window as in our case we have a large number of OneNote Notebooks as we utilize the Office Planner
