Microsoft will be phasing out tls 1.0 and tls 1.1 in Office 365 later this year. This will happen from October 2020. The company had previously postponed the phase-out due to the outbreak of the corona virus. A date was already known for Microsoft’s browsers.

Microsoft mentions October 15 in an update to a blog post about Office 365. Versions 1.0 and 1.1 of the transport layer security protocol are no longer supported in Office 365 from that date. Microsoft expects few problems with that, since the vast majority of users successor tls 1.2 is already left. This is also the case in the Office software, for example. In addition, the company emphasizes that TLS 1.0 and 1.1 have no known security vulnerabilities.

Several tech companies have been phasing out outdated TLS for some time. Browser makers Mozilla, Google and Apple, like Microsoft, have been warning against its use for years. At the beginning of this year, the intention was to phase out TLS in the first half of 2020, but in many cases this was postponed. Microsoft also decided to postpone the phase-out. For the browsers Internet Explorer and Edge, the older TLS protocols can no longer be used from 8 September.
