As communicated in MC220490 (August ’20), Microsoft 365 apps and services have been focusing their efforts on modern browser support over the last year. Beginning August 17, 2021, Microsoft 365 apps and services will no longer support Internet Explorer 11 (IE11) and users may have a degraded experience, or be unable to connect to, those apps and services. These apps and services will phase out over weeks and months to ensure a smooth end of support with each app and service phasing out on independent schedules.
