As of mid-August 2021 Glow users will no longer be able to use Internet Explore and the Edge legacy browsers to access some services in Glow, such as Office 365. We recommend using Chrome to access Glow when in school to have access to all your applications. Using your Windows devices at home you can chose between Chrome or an up to date version of the Edge browser, if you have them available, as both will work with with your Glow account.
