Microsoft has announced that it will reduce support for Microsoft 365 on Internet Explorer 11, and will kill off its old Edge browser.
From 30 November 2020, Microsoft Teams will no longer be supported on Internet Explorer. From 17 August 2021 all other Microsoft 365 apps and services will no longer be supported.
As well as the reduction of support for those still using Internet Explorer 11, Microsoft will also end support for its older Edge (Legacy) browser on 9 March 2021. Microsoft are encouraging all users to utilise the new Microsoft Edge browser, which is built on Chromium.
This will mean that customers using the Internet Explorer 11 and Edge (Legacy) browsers will have a degraded experience and/or will be unable to connect to Microsoft 365 apps and services. New Microsoft 365 features will not be available and certain features may stop working. No further security updates will be released either.
Please find dates for end of support below, for ease:
- Internet Explorer 11 for Microsoft Teams from 30 November 2020.
- Internet Explorer 11 for all Microsoft 365 apps and services from 17 August 2021.
- Microsoft Edge (Legacy) browser from 9 March 2021. NB. the latest Microsoft Edge will continue to have full support.
To clarify, these are icons that you will see for Microsoft’s three browsers:
 |
Internet Explorer — being deprecated in 2020 | |
 |
Old Edge (Legacy) — being deprecated in 2021 | |

New Edge (Chromium) ‐ current, use this one |
