Deprecating support for 3DES
Since October 31, 2018, Office 365 no longer supports the use of 3DES cipher suites for communication to Office 365. More specifically, Office 365 no longer supports the TLS_RSA_WITH_3DES_EDE_CBC_SHA cipher suite. Since February 28, 2019, this cipher suite has been disabled in Office 365. Clients and servers that communicate with Office 365 must support one or more of the supported ciphers. For a list of supported ciphers, see TLS cipher suites supported by Office 365.
