For some reason or another, THUNDERBIRD doesn't recognize the settings for OUTLOOK (HOTMAIL). I have tried every setting suggested for Imap and for Pop3 and Thunderbird still says:
And it doesn't matter which settings, I use, because this is the ERROR, I get
UNABLE TO LOG IN AT SERVER. PROBABLY WORNG CONFIGURATION, USERNAME OR PASSWORD !!!!
So what is the problem?
When using Oauth2 for example to connect an existing IMAP account at Google Mail, Thunderbird uses the local http(s) tcp-ports as a call-back-URL. If you run a local web-server this call-back will not work. I'd say this is bad behaviour. It it is really needed to use a http-callback, it should check which ports are available. Or at least give some feedback to the user that the ports are needed. So my proposals are in this order:
1) use a different method than a local http-port if possible
2) check for free ports and use one of them
3) give a warning that the ports are needed
Yep - I'm beginning to concur. I've been with this for many years, and made donations, but every 18/24 months, it won't give access to my accounts, saying "try another password". It was ok till yesterday, now several accounts are effected - yet again.
For many years, Mozilla used to says it's the fault of Google/hotmail/outlook etc - nothing to do with us. But if you look into it, it's a common fault, that they can't/won't fix.
I'm desperate to use my laptop at present, but can't put up with this yet again, and again.
There is nothing wrong with the addresses or passwords when used on the phone,,,,,,, it's down to mozilla/thunderbird.
I'm also looking around for an alternative..
Good luck out there.
After a lot of reading around, and trial and error, this is what I found out, and what finally got my outlook and gmail accounts working again in Thunderbird 115:
Outlook, gmail, yahoo have deprecated basic username/password authentification, and are now requiring OAuth2 authentication. SMTP authentication has been restricted or in some cases, completely disabled. These providers require permission to place cookies for OAuth2 to work smoothly. Here's what worked for me:
1. In Thunderbird, Settings, Privacy and Security, tick "Accept cookies from sites", including "Accept third party cookies". Outlook and gmail require this.
2. In Thunderbird, Tools, Account Settings, set the Authentification method to OAuth2.
3. Next, follow exactly the instructions given on the Mozilla support site, at the link here: https://support.mozilla.org/en-US/kb/microsoft-oauth-authentication-and-thunderbird-202 . The relevant part is number (2) on the list: "use the config editor to filter for "oauth2", find the appropriate server(s), and delete the entries for "oauth2.issuer" and "auth2.scope".
More info about the Config Editor can be found here: Config Editor (explicit path: https://support.mozilla.org/en-US/kb/config-editor)
3. Restart Thunderbird and provide the passwords for your accounts in the pop-up windows as prompted.
Outlook and gmail accounts throw out big, white pop up windows, where you need to log in then click YES to allow Thunderbird to access them. They look like this: https://answers.microsoft.com/en-us/outlook_com/forum/all/managing-apps-and-services-connected-to-ou...
Do this for each account to make it compatible with the new authentication protocol of outlook or gmail. It will then send and receive mails through Thunderbird again.
This worked for me. I hope it helps someone else out there too!
