Thunderbird version 78.4.1 pour windows 10 - pb avec pièces jointes volumineuses
Bonjour, Je rencontre un soucis particulièrement gênant depuis quelques temps. Je ne peux pas envoyer de mails avec des pièces jointes volumineuses (+ de 3 MO environ). A chaque fois le msg d'erreur " L’envoi du message a échoué. Le message n’a pas pu être envoyé car la connexion au serveur sortant (SMTP) « smtp.orange.fr » a expiré. Veuillez essayer à nouveau" apparaît au bout de quelques minutes. Je ne sais pas si le problème vient de mon fournisseur d'accès Orange ou de votre logiciel ? Mais pour votre information, j'ai essayé avec Outlook et je n'ai pas ce problème ! Mais comme j'utilise votre logiciel depuis des années et que je ne désire pas en changer car il est convivial et simple d'utilisation comparé à d'autres, j'aimerais bien trouver une solution à mon problème . Je vous remercie Cdlt, Grégory76

I've been having a particularly embarrassing problem for some time now. I can't send e-mails with large attachments (over 3 MB). Each time the error msg "Sending the message failed. The message could not be sent because the connection to the outgoing server (SMTP) "smtp.orange.fr" has expired. Please try again". appears after a few minutes. I don't know if the problem comes from my Orange access provider or from your software? But for your information, I tried with Outlook and I don't have this problem! But as I have been using your software for years and I don't want to change it because it is user-friendly and easy to use compared to others, I would like to find a solution to my problem . Thank you very much for your help. Grégory76
As long as you have the correct settings for the outgoing server, smtp.orange.fr on 465, SSL/TLS, the most likely cause of timeouts is an antivirus program scanning outgoing mail. What is the antivirus and its settings? The TB profile folder should be excluded from AV scanning. The message size limit for Orange is 25 MB, so that is not an issue.
Hello, Thank you for your reply, I am using Bitdefender Total security. I checked the firewall and it clearly indicates that thunderbird is excluded from the scan. So I don't think it's from the anti-virus. Especially since when I use Outlook, it works with large attachments! What do you think ? Thank you. cordially Gregory76
The most reliable way to see if an antivirus is affecting TB is to run Windows in safe mode, which bypasses startup apps such as AV. Even then, you may have to adjust Bitdefender's startup options so it doesn't launch in Windows safe mode. Bitdefender has been the source of numerous complaints on this forum.
