The following errors are regularly found in "System" log on Exchange server:

An TLS 1.2 connection request was received from a remote client application, but none of the cipher suites supported by the client application are supported by the server. The SSL connection request has failed.

It is clear they are coming from Active Sync or OWA.

How can I determine who device is causing that?

I checked all logs in TransportRoles\Logs but was not able to find.

Thank you.
