I want to setup a email router for Dynamic CRM 365 for incoming (POP3s) & outgoing (SMTP) email with IBM Lotus Domino as the mail server .
When I clicked on the "Test Access" in the "Users, Queues & Forward Mailboxes", I get this error message for incoming email setup (POP3s)
"Incoming Status: Failure - A call to SSPI failed, see inner exception. The function requested is not supported "

I have enabled the log and checked the event viewer. Here's the log:
#26090 - An error occurred while opening mailbox HELLOWORLD/Ck/ACC@ACC. System.Security.Authentication.AuthenticationException: A call to SSPI failed, see inner exception. ---> System.ComponentModel.Win32Exception: The function requested is not supported --- End of inner exception stack trace --- at System.Net.Security.SslState.StartSendAuthResetSignal(ProtocolToken message, AsyncProtocolRequest asyncRequest, Exception exception) at System.Net.Security.SslState.ProcessReceivedBlob(Byte[] buffer, Int32 count, AsyncProtocolRequest asyncRequest) at System.Net.Security.SslState.StartReceiveBlob(Byte[] buffer, AsyncProtocolRequest asyncRequest) at System.Net.Security.SslState.ForceAuthentication(Boolean receiveFirst, Byte[] buffer, AsyncProtocolRequest asyncRequest) at System.Net.Security.SslState.ProcessAuthentication(LazyAsyncResult lazyResult) at System.Net.Security.SslStream.AuthenticateAsClient(String targetHost) at Microsoft.Crm.Tools.Email.Providers.Pop3Client.Connect(Boolean useSsl) at Microsoft.Crm.Tools.Email.Providers.Pop3PollingMailboxProvider.OpenMailbox() at Microsoft.Crm.Tools.Email.Providers.CrmPollingMailboxProvider.Run()
