how to enable TLS 1.2 for exchange 2010 sp3

Hi all,

recently we are encountering certificate error when access OWA from Chrome (your connection is not fully secure , the site uses is outdated security configuration).

in the the SMTP logs i found following:

"TLS protocol SP_PROT_TLS1_0_SERVER negotiation succeeded using bulk encryption algorithm"

Note: we are using exchange 2010 sp3 RU 30 in win 2008 R2 sp1

please advise me to resolve this issue.

 thank you
