TLS 1.2 mandatory on Office 365 by june 2020

New Contributor



According to TLS 1.2 will be mandatory by june 2020 to access Office 365 services.


A lot of Microsoft announcements were postponed due to COVID 19. This one will be subject to postpone or not ?

Because a lot of environments always use TLS 1.0/1.1 (including medical environments) and it will be very difficult to perform any modification on the production systems.

If postponement happens, it will certainly be announced on the blog spaces here, so keep an eye on those. But COVID in general should not be an excuse to overlook the best security practices, including disabling older SSL/TLS versions, basic authentication and so on.

Totally agree! It is for that I opened this post.
I keep an eye on Microsoft blogs.
