Thunderbird certificate email error


It says wrong certificate and even when I try to add permanent exception, it still won’t let me log in to email.
Cloud account works great, but the odd thing is, email doesn’t…

I would be interested to know if anyone else has had this problem recently.

Mail certificate "not secure" - says Thunderbird

I have exactly the same problem since yesterday. «Voir…» on «État du certificat» shows clearly that the certificate is expired at the 8th of July.


I have exactly the same problem using Thunderbird on PC and K9 Mail on my smartphone. Since the 08/07/2017 as well…



We are working on it. It should be fixed in a few hours. Sorry about that



Sorry for the issue, it has been fixed.



Bonjour, même problème pour moi ce matin sur Thunderbird depuis mon PC et K9 Mail sur mon mobile. Thunderbird m’indique que le certificat a expiré (période de validité du 09/04/2017 au 08/07/2017).
Merci d’avance pour votre aide.


Sorry about that, its now fixed


Everything is ok !
Thanks a lot.
