Are you using selfsigned certificate ? Run the command Get-Exchangecertificate on all CAS servers see the certificate status is showing as valid or invalid.

Try this:

Exch server Receive connector, Authentication tab

Transport Layer Security (TLS) --> enabled

Basic Authentication --> enabled with "Offer Basic auth only after TLS" enabled

Integrated Windows authentication --> enabled

OL client, POP3 profile

Incoming POP3 server --> port 995, SSL required

Outgoing SMTP server --> port 25, TLS encryption enabled

Outgoing mail server (SMTP) requires authentication enabled

SPA enabled

 function, operable program, or script file. Verify the term and try again.

Did u paste the certificate thunmbprint?  See the attached screen shot to find out the thumbprint, while pasting it you will need to remove all the sapce.  Also make sure that you are running the command on CAS server.
