This may be stupid, but I'm new to OneNote and am not sure of the best way to
work with it...

I had a notebook, with a section, with a page that contained a copy of an
Outlook task. Within that task was an embedded message.

Yesterday, I was EDITING the contents of that message. It was a
work-in-progress, so I had the message open most of the afternoon.

At the end of the day, I started getting synch errors in my OneNote notebook.

I thought I handled them correctly but, today, when I open that message in
that task in that page in that notebook -- all of my edits from yesterday are
gone.

Do I have any hope of recovering that work?

The task in Outlook also has lost the edits (is that the same task, or a
disconnected copy?).

Any advice?
