Note: After switching the license it also switches your linked OneDrive/SharePoint Sites to your Western account as well. To switch these back to your Ivey files, choose the 'Switch account' link shown below on the Account tab and choose your Ivey account. The licensed area will still show your Western account. If you want both account files to show you can add the other using 'Add a service' below the Connected Services.
