24 Jul Encryption changes on 31st October 2018
12 months ago, Microsoft announced that they were changing their Transport Layer Encryption requirements for connections to Office 365.
Initially, they planned to stop the use of TLS 1.0 and 1.1 in March 2018, however they extended this to 31st October 2018 which is fast approaching.
So how will this affect you?
As of October 31, 2018, Microsoft Office 365 will no longer support TLS 1.0 and 1.1.
All Office 365 Services as of 31st October 2018 will have to use Transport Layer Security (TLS) 1.2 or later to be able to connect without issues to the Office 365 Services, this may require updates to browsers and client-server software.
If you connect to Office 365 via a Browser and are using any of these browser versions then you should upgrade to a later version:
- Android 4.3 and earlier versions
- Firefox version 5.0 and earlier versions
- Internet Explorer 8-10 on Windows 7 and earlier versions
- Internet Explorer 10 on Win Phone 8.0
- Safari 6.0.4 / OS X10.8.4 and earlier versions
If you are using Windows 7, then you need to check that TLS1.2 is the default secure protocol for WinHTTP, This Link can help you with this.
