A family of Microsoft products that enable users to capture, organize, and reuse notes electronically.
Here is a solution that I found that works for me. It adds an extra step, but at least it's a simple one.
My Surface Pro 4 came with the software Drawboard PDF. If I open the pdf in drawboard and then within that app, print it using the "send to onenote" option, I am able to change it to landscape and it inserts properly.
If your computer doesn't have Drawboard, it looks like it's about $10 in the Windows Store.
Hope this helps!!
