The SSL connection request has failed


I am getting an error from our Exchange Server 2007 on Windows 2008 once everyday and time seems to be random.

ID= 36874; Src= Schannel; User= ; Catg= ; D/T= 03/12/2015 02:06:38; EventDesc= An SSL 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.

No users are having any connection problems but I am not sure about why the server is constantly reporting the error message. A few users are using their mobile to connect to Exchange via SSL VPN, would this be the cause?

SSL has been vulnerable to many exploits so it has been replaced by TLS some clients are trying SSL and getting rejected by the server but they are continuing down the security suites until they find one that both the client and server have

Does Exchange 2007 support TLS?
David Johnson, CD, MVPOwnerCommented:
yes exchange supports TLS indirectly since cypher suites are configured for the operating system.
Maybe someone is scanning your system, or a legitimate user is trying to connect and is having problems. If your system is publicly accessible I suggest running a report from SSL Labs to see what your configuration is. You can then adjust the settings on the server to make sure that the server is as secure as possible while still providing compatible connections to your clients.

Any change you make will require that you restart the server. :( If you have any other SSL/TLS severs, I suggest fixing those first so you have the cipher suite and TLS and SSL registry settings correct before you have to do a bunch of reboots on the Exchange server,
