"Could not connect to server mail.atmc.net; the connection was refused" message after the installation of version 149.0. I've verified my server settings & turned off the firewall setting & it still won't connect. It worked find before 149.0 installation.

I have been using Thunderbird for ages now with no problem, but I suddenly realised that no recent emails were appearing from my Gmail account. I have tried everything suggested on line to resolve the problem, including uninstalling and reinstalling Thunderbird, and deleting and re-entering my acccount details but neither the IMAP or SMTP servers will connect to Gmail. I have reset all of the server settings on Thunderbird, and have checked that Gmail is IMAP compliant (which, apparently, is is now automatically). I have spent hours trying to sort this out and am just at the point of abandoning Thunderbird completely, but I am loathe to do so if there is a solution. The latest error message i have received is "Unable to log in at server. Probably wrong configuration, username or password" but I don't know what else I can check or change.

Bonjour, Les mails n'arrivent plus automatiquement dans ma boite mils et quand ils arrivent ils ne s'ouvrent pas (ou alors 2 jours après...). Message : le certificat pour imap.gmail.com.993 ne provient pas d'une source sûre ! La fenêtre "Ajout d'une exception de sécurité" s'ouvre et rien ne fonctionne si je clique sur "obtenir le certificat" ou "confirmer l'exception de sécurité"....J'ai tout testé sur cette fenêtre... Je ne suis pas du tout informaticien... Pouvez-vous m'aider rapidement ? Merci. TAMINIAU Yvan yvan.taminiau@gmail.com

Hi,

I have three outlook.com email accounts configured. Two accounts open to show all subscribed folders. One account shows the account name only, but no folders.

Activity manager shows: "The current operation on 'Outbox' did not succeed. The mail server for account wasaga72@outlook.com responded: Command Error. 12"

Sometimes all folders show. Sometimes all folders show after a delay.

Tried: 1 deleting all .msf files. 2 removing and re-adding the account

My wife and I both have identical Laptops with the same three outlook.com accounts. Mine using version 148.0.1 (64-bit), hers using 140.8.0 esr (64-bit) both have the same problem.

Any help would be appreciated,

John

I am currently unable to login into my Thunderbird account. My email provider (Internet Lightspeed) told me to go into Tools>Settings > Privacy & Security > Certificates > Manage Certificates. In the Certificate Manager, go to the Servers tab, click Add Exception, enter the server address which is imap.lightspeed.ca. I did that and got the following response: This site provides valid, verified identification. There is no need to add an exception.

The Certificate Manager/Servers window now shows imap.lightspeed.ca:443 as the Server. Lightspeed says that is correct and need to contact Mozilla Thunderbird. Thunderbird updates are current. Any suggestions? Patrick

Hi there, it seems I'm suffering from the same problems as others in several countries. I have also not been able to access my gmx.com account via Thunderbird for about a week now. I live in Belgium and use a Proton VPN, in case this is relevant. I can't find how to delete cookies in history, nor any other potential solutions to the problem. Any help offered is greatly appreciated! Best, Doreen
