Unable to setup incoming email (POP3s)(Port 995) using Dynamic CRM Email Router

Posted on by

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

Any suggestions? Appreciate your help.
