Hi, our company is using a program called Visma Administration 1000 as economy system. Since we have macbook computers we thus have a Microsoft Remote Desktop downloaded, since the economy system only works through Windows! Anyhow, we then use Thunderbird as a local e-mail which is connected to the economy system, and through which we can send our orders, invoices etc to our email. However, ever since a few weeks back a troubleshooting messege has occured making us unable to send the emails; referring to a problem with the outgoing SMTP server. However, after speaking with an IT Support guy who looked it thorugh he said that everything looked like it should. BUT I am wondering if it might have anything to do with the server/thunderbird being blocked by the program, which I don't know how to check... Does anyone know how to fix it? The error message is in swedish but translates to: "The message could not be sent. The message could not be sent because the connection to the outgoing server (smtp01.binero.se) failed. The server may be unavailable or is denying connection to the outgoing server (SMTP). Please check that your outgoing server (SMTP) settings are correct and try again." I really appreciate any help I can get!! Thank you in advance, kind regards Ella
