5 STEPS
1. The first step is to navigate to the Sharepoint site that you want to Link to Onedrive
2. Select the document Library that you wish to Link to Onedrive. Typically this will be named Documents but not always.
3. Select "Add Shortcut to Onedrive"
DO NOT USE SYNC, the sync feature can cause issues with onedrive syncing on your local machine.
4. Now when you navigate to your onedrive, whether it be in the web or file explorer you should see the shortcut to your sharepoint documents.
5. That's it. You're done.
