I just downloaded thunderbird on my OS Catalina. It won't let me switch to pop. I get a message that thunderbird is not an imap4. The server settings only show it as an imap. When I put in pop and 995 port it won't work. How do I switch?? Email address and password are correct. It works as an imap.

On TB v78 the minimum requirement for SSL has increased and probably your email service provider still use deprecated security for the mail server. Can you try to set a lowest security by following below steps and let us know how it works?

From the menu at the top right, go to Options. Scroll all the way to the bottom and click on Config Editor -> Skip past the warning. Scroll down until you find security.tls.version.min (or paste security.tls.version.min to upper frame) Change the value 3 to 2. Restart TB. If it's still not working then change again same option but this time to 1. Restart TB.
