Hello there mareikepirk83. We have read your message. We try to help you. Oké there does Thunderbird continuously ask for a password? your inlog code for Thunderbird just works, oke? It is a problem with the Outlook login? the message about the Smtp part. is it possible to send us a photo of it, or send the entire error text and from pop ups as well. You may be entering the password correctly.you want to do the next step. And it gives you the Smtp (server)message. But further steps cannot be taken because, for example, Smtp entries have not been entered correctly for Outlook and Thunderbird.or being blocked. send us a picture please from the error text. If you can get in to Thunderbird see if your Smtp setting are oke. https://support.mozilla.org/en-US/kb/cannot-send-messages#w_verify-your-smtp-outgoing-email-settings https://support.mozilla.org/en-US/kb/how-do-i-create-screenshot-my-problem https://support.mozilla.org/en-US/kb/manual-account-configuration Greetings Firefox volunteer.
