Hi Jason,
You can find your OneDrive CID in several ways. First, try sharing a file with yourself and opening the shared link in a browser the CID is often included in the URL. Another option is to visit Microsoft’s account summary page, view the page source (Ctrl+U), and search for CID= in the code. Lastly, you can open OneDrive in a browser, press F12 to launch Developer Tools, go to the Network tab, refresh the page, and look for any requests that contain CID=in the URL.
Please let us know if these steps help resolve the issue, or if you need further assistance. We're here to help!
