Email account settings work on PC, but not on MAC

Hi,

A few months ago one of my email accounts stopped working (doesn't download any mail, can't send emails) in Thunderbird on my MAC (I had been using it successfully for a few years). I think it corresponded with a change in security certificates from the email provider. And I can't seem to get it to work on Thunderbird again, despite a lot of attempts. It works in webmail on my computer, so I am assuming it is not an issue with the certificate. I know the settings are correct, since I have spoken to someone who provides tech support for the email server and it works on a PC. Both the MAC and PC are running Thunderbird 31.6.0. I have other email accounts with gmail that I use in Thunderbird that are working just fine. For Incoming for the problem account I am using IMAP, Port 993, XXL/TLS with Normal Password authentication. For outgoing I am using SMTP, 465, SSL/TLS, normal password. These settings work on the PC I have (all email downloads, I am able to send). I tried removing Thunderbird and re-installing it on the MAC, but that did not seem to make a difference. Does any have any other idea what I should try?

Thanks!

Can you post your Troubleshooting Information? Help (Alt-H) - Troubleshooting Information

Please indicate which one is the troubled account.

Why should it? The problem is almost certainly in your profile. And that won't be touched when you re-install Thunderbird.

one of my email accounts stopped working

Do you get any certificate error?

Check wether you have this cert in your Thunderbird certificate store: RapidSSL SHA256 CA - G3 Fingerprint: 0e34141846e7423d37f20dc0ab06c9bbd843dc24

If not, talk to your email provider or get it directly from here: https://ssl-tools.net/certificates/nakw2x-rapidssl-sha256-ca-g3

Import it into your Thunderbird certificate store.

Thanks for your assistance. I tried that but it doesn't seem to have fixed the issue. Any other ideas to try?

Hi,

I went to that page (https://ssl-tools.net/certificates/nakw2x-rapidssl-sha256-ca-g3) and clicked on the PEM file to download and it said:

"ALERT: This certificate is already installed as a certificate authority."

So I manually downloaded it (By right clicking and saving as) and went to Certificate Manager in Thunderbird and manually imported it. Looks like I now have two of those certificates (see attached image). I think retried adding the troubled account, but it is doing the same thing as before (not loading).

Should I uninstall both certificates and reinstall? Any other ideas for troubleshooting?

Thanks!
