OSError: [WinError 10013] An attempt was made to access a socket in a way forbidden by its access permissions

This error occurs because the port 5000 is already in use by another application. Identify what's using the port with netstat -na | findstr "5000" and pslist with whatever process ID netstat reports (right most number). (thank you https://stackoverflow.com/questions/2778840/socket-error-errno-10013-an-attempt-was-made-to-access-a-socket-in-a-way-forb)

(onenote) PS C:\Users\Matt\code\onenote_export> netstat -ano|findstr "5000"
  TCP    0.0.0.0:5000           0.0.0.0:0              LISTENING       9348

(onenote) PS C:\Users\Matt\code\onenote_export> pslist 9348

At this point you can kill the process with pskill {process_id}, if you know you don't want whatever that other program is doing (svchost in my example). Or change the port being used in onenote_exporter.py, and the associated Azure app (from setup portion of Readme).

it's netstat -ano not netstat -an. o adds the owning process-id to the output,
