Unable to add personal Hotmail/Outlook.com account via IMAP with OAuth2 Hi, I'm unable to add my personal Microsoft account (@hotmail.com) to Thunderbird via IMAP despite trying every solution I could find. My setup:

Thunderbird (latest version), macOS Sequoia 15.6.1 Account: personal @hotmail.com

What I have tried:

Manual IMAP configuration with both smtp-mail.outlook.com and smtp.outlook.com as outgoing server OAuth2 authentication — the Microsoft login window opens, I successfully log in, but Thunderbird still throws "Unable to log in at server" Enabled cookies for all Microsoft domains (outlook.com, login.live.com, login.microsoftonline.com) in Privacy & Security settings Enabled 2FA on my Microsoft account and generated an App Password, then tried with Normal password authentication — same error Toggled the experimental Account Hub off and on, tried both the new and old account creation flows Restarted Thunderbird multiple times between attempts

What works: My institutional Microsoft 365 account (@hnu.de) connects and syncs perfectly with identical IMAP/OAuth2 settings. The issue appears to be specific to personal Hotmail/Outlook.com accounts. Has anyone successfully connected a personal Hotmail account recently? Any help is appreciated.

Manual IMAP configuration with both smtp-mail.outlook.com and smtp.outlook.com as outgoing server OAuth2 authentication

Why manual? Why don't you let Thunderbird automatically pick the correct server names? Follow the instructions in this support article, and use the correct outgoing server name. https://support.mozilla.org/kb/microsoft-oauth-authentication-and-thunderbird-202

Enabled 2FA on my Microsoft account and generated an App Password

With OAuth2 authentication you cannot use an app password. Use your main account password.
