Office 365 Services moving to TLS 1.2

By | December 21, 2017

Starting on March 1, 2018, all client-server and browser-server combinations must use TLS 1.2 or later protocol versions to be able to connect without issues to Office 365 services. This may require certain client-server and browser-server combinations to be updated.

Although current analysis of connections to Microsoft Online services shows that very few customers still use TLS 1.0 and 1.1, we are providing notice of this change so that you can update any affected clients or servers as necessary before support for TLS 1.0 and 1.1 is disabled. If you are using any on-premises infrastructure for hybrid scenarios or Active Directory Federation Services, make sure that these infrastructures can support both inbound and outbound connections that use TLS 1.2

    Howdy! I could have sworn I’ve been to this blog before but after going through a few of the articles I realized it’s new to me. Anyhow, I’m definitely happy I found it and I’ll be bookmarking it and checking back often!
