re :Thunderbird keeps going offline

If offline then Thunderbird is not using the internet, so cannot connect.

Do you have internet connection up and running? Are you talking about pop or imap or both types of mail account ?

Is Thunderbird offline? In bottom far left of 'Status Bar' - Do you see a 'two blue screen icon' or a 'two black screen icon' ?

If 'two blue screen icon' then you are in 'online' mode. If 'two black screen icon' then you are in 'offline' mode.

Is Thunderbird setup to start in offline mode ? 'Menu icon' > 'Options' > 'Options' > 'Advanced' > 'Network & Disc Space' tab click on 'Offline...' button select 'Automatically follow detected online state' click all 'OK's

@bbonne, you have asked the same question three times in less than 24 hours. Please refrain from duplicate requests. It is not only confusing but wastes the time of volunteers trying to assist you. You now have responses from three individuals that probable help you little because they are all looking at the problem from slightly different angles.

I am so sorry I kept posting. This whole support system is new to me. I didn't see the question coming up which is why I repeated it. In the end, nothing I tried worked so my MAC is going back to my server tomorrow for him to try to figure out. The problem was new to him and he's been in the business for years . Thanks so much for your time.

Thank you for the answers, as I had this question also.
