Hi, my environment running Exchange 2010 SP2 with POP3 enabled. After I restarted server two days ago, then the POP3S users are unable to receive email with error below:
Log onto incoming mail server (POP3): Your server does not support the connection encryption type you have specified. Try changing the encryption method. Contact your mail server administrator or Internet service provider (ISP) for additional assistance.
I have verified TLS is checked on Receive Connector and port 995 is configured on CAS POP3 setting as per working condition before restart the machine.
Please advise any resolutions. Thanks!
Sean
