hello,

we have debian9 64 bit with iredmail opensource

we were testing activesync connectivity using a windows 7 machines with outlook connecting to our debian server

during our tests we found that outlook activsync would not connect to the debian server on which iredmail was installed
the error that we received in the nginx log file was that tls version was lower
to fix this we had change the nginx configuration on debian to support tls version tls1.0 and 1.1 by modifying nginx ssl conf file as follows

ssl_protocols TLSv1.2;
to
ssl_protocols TLSv1.2 TLSv1.1 TLSv1.0;

anybody else on this forum experience similar issues ?

i would prefer not to allow nginx to accept connections less than tls1.2.

how to resolve this ?

thanks,
rajesh
