It really has nothing to do with the block SSL 2.0 communication setting per se. Eset sees the client will only except SSL. During the connection handshake, e-mail server says it is using TLS. It is starting to appear that Eset is now keying off of the type of encryption used from the e-mail client. However, it appears to only manifest if the e-mail client is using the SSL versus SSL/TLS setting. When Eset has the block obsolete enabled, it blocks this traffic which is incorrect as its not using SSL 2.0 or lower at this time. The external ip address is clarified to represent what resolved to at the time of testing. In the attached you can see I have Outlook set to SSL, connecting to imap and smtp gmail servers, the wireshark packets showing the TLSv1.2 Server Hello message with the Cipher Suite used AES 128 with SHA 256.

Just did some testing, as I suspected when Outlook 2013 or higher is set to "SSL" (2016 or higher actually labels it as SSL/TLS) it tries to negotiate TLS first. G Suite supports TLS versions 1.0, 1.1, 1.2, and 1.3. TLS is an industry-wide standard based on Secure Sockets Layer (SSL) technology that encrypts mail for secure delivery. When using G Suite, be aware that all settings that mention SSL now use TLS. Transport Layer Security (TLS) has replaced SSL.

I'm going to run Wireshark and try to get the exact version SSL or TLS a pc negotiates for our email clients that didn't work. I suspect they are negotiating TLS instead, in which case if the version is high enough it would fall back to being an Eset issue - where they are incorrectly identifying which traffic to block via that obsolete setting. Its possible GSuite and Outlook are doing the same dance. It would be more accurate to label "SSL" as "SSL/TLS" in Outlook GUI. I can verify that Office 365 works the same way in the background. That even if Outlook 2013 or higher is set to just Imap with "SSL" in the GUI, that in the background Microsoft will actually try to negotiate the highest encryption possible (TLS 1.3) and then work its way backwards until client and server agree. From Gsuite website it looks like even if you set for SSL it just uses TLS instead.

Windows 10 claims no SSL 2.0 support out of the box (and we didn't use registry to enable). I'm not sure what to think at this point.

with Windows 10%2C version,and is no longer supported.&text=Because of the similarities between,where they differ from TLS. Because of the similarities between these two protocols, SSL details are not included in this documentation, except where they differ from TLS. Beginning with Windows 10, version 1607 and Windows Server 2016, SSL 2.0 has been removed and is no longer supported.Īpplications that require a high level of interoperability should support SSL 3.0 and TLS. TLS supersedes SSL 2.0 and should be used in new development. TLS is a standard closely related to SSL 3.0, and is sometimes referred to as "SSL 3.1". *Note: We have made no registry changes to force enabling SSL 2.0 or lower, it is very much the out of the box Windows 10 setup with regards to SSL / TLS It should only have SSL 3.0 as an option for SSL:

Also I've been researching and Microsoft Outlook 2013 as of July 2015 patch while running on Windor later should have SSL 2.0 disabled by default.
