Hello,
Is there a way to force TLSv1.2 with Java 7?

My code is simply connect and read some calendar items. The code has always work with on-premise Microsoft Exchange Server 2010. Now I try to connect to outlook.office365.com and I get "Conenction reset" error. If I use jdk-13.0.1 the code run fine.

The environment that I'm in forced me to stick to jdk1.7.0_55. In my search for answers Java 7 by default is set to TLSv1 and it is proven by the trace. TLSv1.2 is the default in Java 8 onward and it looks like outlook.office365.com require TLSv1.2.

Error:

`
