Outlook error when sending/receiving

Outlook error when sending/receiving

When I do a send/receive in Outlook I get the following error message:
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...
Send test e-mail message: Your server does not support the connection encryption type you have specified. Try changing the encryption method. Contact your...

This was working and then suddenly stopped.

I have Outlook configured as per your specs:
Incoming server: pop.zoho.com, Port: 995, SSL
Outgoing server: smtp.zoho.com, Port: 465, SSL

In the Zoho Mail Settings, I have POP enabled.

Any suggestions?
