In summary, as of July 2015, Exchange currently supports TLS 1.0, but can also support TLS 1.1 & 1.2 with the following minimum requirements met:

Protocol	TLS v1.1/1.2 Minimum Requirements
SMTP	Exchange 2013 CU8 or Exchange 2010 SP3 RU9
POP/IMAP	Exchange 2016 Preview
HTTP (server)	Windows 2008 R2; MAPI clients must run Windows 8.1 or later
HTTP (proxy to MBX)	Exchange 2016 Preview

You enable or disable per server in the registry:

Hi Anil,

Thank you for your question.

In addition above suggestion, enabling support for TLS v1.1 and v1.2 are highly recommended. But leaving TLS 1.0 enabled is a good thing for now. Clients and applications should always prefer the most secure option, provided that Windows, the application, and the client all support it.

If there are any questions regarding this issue, please be free to let me know.

Best Regard,

Jim
