Hello, This morning I did try to ad my iCloud email address account to Thunderbird. I already got an email account in Thunderbird but that will stop within a few months. I did find the needed information on my iPhone: My name for the use off capital and lowercase letters; my iCloud email address; my password which is my Apple ID, I presume. The result is: 'It is not possible to log in to the server. Probably an incorrect configuration, username or password'. The username and password are correct (got it from my iPhone, and the mailserver iCloud does work perfect on my iCloud mailprogram (iPhone, iPad, PC). So maybe the configuration, see appendix, isn't ok but I did get that from Thunderbird. Do I overlook something? Thanks for helping.
