Outlook e-mail encryption "security": 3DES and SHA1.
Does anyone know why these very outdated security algorithms are the only available ones in Outlook 365? This does not really seem that secure to me, considering both algorithms are very old and cons...
Cipher support depends on the operating system used and which is agreed upon by both ends. My current connection uses TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384. Support for older versions of TLS (<1.2) will be dropped in October - see https://support.microsoft.com/en-us/help/4057306/preparing-for-tls-1-2-in-office-365
Hello Michel,
Thanks for the reply , So is it means while using the Encryption TLS 1.2 can Change/Support the outlook Encryption Algorithm other than 3DES and RC2 (which is currently using)
Attached SS.
Are you using a moder Outlook version? Outlook 2013/2016 and for O365 supports AES 256.
