We tried literally everything, turned out - ISP blocked ports for whatever reason they had. 5 minute phone call solved the problem. Thanks for the input tho.

Hello there

These issues can be dealt with quite simply by deleting these accounts, requesting new ones and the , it works again. But if you show patience for this situation and can contact your provider to ask what situation it is playing now, fill in the similar SMTP configuration that your provider will have to give you if you have contacted it. The situation you prescribe to us is good but not a problem on our part Thunderbird.

try to reach your email provider Gmail – Google ask for a manager there or first line help for your query to the configuration settings of their SMTP settings for your configuration that they might provide you.

Hello there

The reason could be that there are more e-mail accounts in your system of 8 PCs that could not have been properly configured or accepted.

You have already been in contact with them, the situation has been clarified on their part, a block for your Port has caused it, okay. You have clearly been assigned a new port number and/or filled in a new configuration
