Hi all,
I want to make the connections with our Exchange server more secure. Plan is to only allow TLS1.2 connections to the servers and rejected connections with TLS1.0/1.1 or even without TLS.
I know that we have several other servers and applications that are connecting to Exchange to send mail (with and without authentication). And off course the Outlook-clients, which I believe are at the right level of TLS.
Right now I want to determine which clients are connecting to Exchange and with which TLS-version. What is the best way to figure this out? I'm sure that I can find this in the Exchange receive logs files, but to diagnose this logs is a huge job.
Are there others ways to easily find out which TLS-version are used?
Hope you can help me with this.
Kind regards,
Arjan
