when you ask a question or have an issue, you need to provide as much information as possible, but you have only said 'I would like to join somebody to help me' which does not explain anything about your setup etc. So please provide: What OS are you using ? Windows 10. MAC or Linux ? What version of Thunderbird are you using? Not sure then 'Help > About Thunderbird' has the info. Are you talking about an IMAP or POP mail account ? Post the following information so we know what server you are using so we can check they are correct. In Thunderbird * Help > Troubleshooting Information * Scroll down to 'Mail and News Accounts' section * Copy all info in that section and paste it into this forum question OR post an image showing the data. Do you get an error message when you click on 'Get Messages'? If yes - post an image of that error message OR type the entire error mesasge word for word.
