Unable to log in at server. Told: Probably wrong confid, username, Password. Can't proceed, don't know what to do! Perhaps nearly there? Need your help. Thank you. I rarely do any detail adjustments, if any, to Thunderbird so I am completely at sea on it! I have not been able to identify my Thunderbird version but must be recent. I think I have managed to get almost there but need your help. I have so much to do but can't proceed with the work that desperately needs doing. Your help would be much appreciated. I am not a natural PC worker, I have managed to extract myself from MS Windows because I don't need all their diverse complicated bits of software. I just want to get on and do the things that really matter. Linux, Thunderbird have been doing all I need. Using Linux and Thunderbird is a breath of fresh air Malcolm Sanderson.
