All,
My understanding is that TLS 1.2 will be required on all connections as of yesterday. However, our exchange server does not support TLS 1.2 (Exchange 2010 sp2) yet I am still able to send emails out through our server side synched email boxes. Does anyone know if the TLS 1.2 has not gone into effect or if it does not apply to the exchange server side synch?
Any ideas?
Hi Johnny - thanks for your Feedback. I have still a little question about this.
Our Customer is using Exchange Online and he ask, if and how he can strictly activate TLS1.2.
Thanks a bunch for your help!

Hi Partner ,
You could follow the following configuration guideline to enable TLS 1.2 in your Exchange environment.
For Exchange Server versions:
Exchange Server 2016
Install Cumulative Update (CU) 8 in production for TLS 1.2 support and be ready to upgrade to CU9 after its release if you need to disable TLS 1.0 and TLS 1.1.
Install the newest version of .NET and associated patches supported by your CU (currently 4.7.1).
Exchange Server 2013
Install CU19 in production for TLS 1.2 support and be ready to upgrade to CU20 after its release if you need to disable TLS 1.0 and TLS 1.1.
Install the newest version of .NET and associated patches supported by your CU (currently 4.7.1).
Exchange Server 2010
Install SP3 RU19 in production today for TLS 1.2 support and be ready to upgrade to SP3 RU20 in production after its release if you need to disable TLS 1.0 and TLS 1.1.
Install the latest version of .NET 3.5.1 and patches.
Exchange Server versions older than 2010
Out of support. There is no path forward and you should be planning a migration to Exchange Online or a modern version of Exchange Server on-premises.
For more environments' configuration like windows server could be referred to the following article:
Hope the above info would help.
Have a nice day.
Regards
Johnny
