Hello,

We are using a Windows Server 2016 as an internal SMTP relay server to forward messages from local servers and software to our Office365 Exchange environment. Since Microsoft has announced that TLS 1.2 will come in the next months, we are looking for a setting in the Windows based SMTP Server (local IIS) for TLS 1.2. Does anybody know how to setup the windows SMTP server to use the new TLS standard?

Thanks for your answers, Regards, Chris

Hi @Chris2364 

 

My understanding is that for Server 2016, TLS 1.2 is enabled by default

 

https://docs.microsoft.com/en-us/windows/win32/secauthn/protocols-in-tls-ssl--schannel-ssp-

I've used https://www.nartac.com/Products/IISCrypto in the past to confirm/change settings.

 

Hope this helps,

Mark
