Probleme mit Thunderbird (Win) und icloud-Mail-account

Hallo,

ich bekomme es nicht hin, auf einem Win10-Rechner mit Thunderbird meinen icloud-Mail-Account einzurichten.
Gibt es hier irgendetwas besonderes zu beachten?
Ich verwende folgende Einstellungen (von https://support.apple.com/en-us/HT202304 [apple.com]) :
IMAP information for the incoming mail server
Server name: imap.mail.me.com
SSL Required: Yes
If you see an error message when using SSL, try using TLS instead.
Port: 993
Username: This is usually the name part of your iCloud email address (for example, emilyparker, not ). If your email client can't connect to iCloud using just the name part of your iCloud email address, try using the full address.
Password: Generate an app-specific password.
SMTP information for the outgoing mail server
Server name: smtp.mail.me.com
SSL Required: Yes
If you see an error message when using SSL, try using TLS or STARTTLS instead.
Port: 587
SMTP Authentication Required: Yes
Username: Your full iCloud email address (for example, , not emilyparker)
Password: Use the app-specific password that you generated when you set up the incoming mail server.


Was mache ich falsch???
