I now get the message "Certificate for the mailbox is not valid for that server. Someone could be trying to impersonate the server and you should not continue". My provider tells me that the certificate is used for a number of emails. Any suggestions please?

Thunderbird only shows the message once and it is not there long enough for a screen shot, regrettably. I have forgotten to mention that I am running Ubuntu.

Can you provide the more specific error code shown in the error pop-up?

Are you running any kind of anti-virus software?
