Greetings from Pennsylvania. I am try to set up Thunderbird using a free Outlook email account; with no luck.I am wondering if one can use Thunderbird with a free account? I will/would go to a paid account but I am reluctant to if I can not get it to work. The AI on Microsoft chat replied yes but I am not convinced. I have gone through numerous web pages looking for answers with no luck setting it up. Problems I have: the server outlook.office365.com has disconnected. the server may have gone down or there maybe an network problem. the current operation on inbox could not succeed. the mail server for the account responded user authenticated but not connected. With: network.dns.disableIPv6 = true And: IMAP Mail Server outlook.office365.com [email protected] SS/TLS OAuth2
