Thunderbird Community Forum

Having established a new Outlook account I cannot sign into it properly with Thunderbird - I get authentication failures each time despite all settings apparently being correct, IMAP enabled in the web browser view of the outlook account and so on. Oauth2 set and all server settings good. I have been over and over things. Tried various suggestions of the web to no avail.

I have tried unsuccessfully with three separate machines - two Microsoft 11 laptops and an iMac. All fail.

I can access the account and send/receive emails from a web browser and I have got it working okay with an iPhone, an Android tablet and a Microsoft email client - but not with Thunderbird. I even get a browser popup on the iMac when I open Thunderbird asking if I am trying to sign in - I say yes and it says I am all signed in - but the email doesn't authenticate. I have passcodes all set up etc.

A separate Hotmail account does work with the same Thunderbird client and has the same server settings (apart from the username obviously).

I am at a loss how to resolve this other than move to a different email application.

Any ideas?

I have two Yahoo accounts in Thunderbird. One uses normal password and works great. For the second one, Thunderbird forced me into OAuth2 and it constantly returns all kinds of connectivity errors. I've tried to re-add the account with normal password, but Thunderbird returns that the password is not correct. What is pCENT? Is there a way to force Thunderbird into using normal password?

Hello Due to a massive cluster**k this morning, I changed my password by accident I think I've now got everything working again, except that Thunderbird cannot sign in to my Google Account What I don't understand is that I have a password with normal and special characters and numbers, but the Oauth2 password is very different of course How do I know what to change my Oauth2 password too? Or perhaps the question should be how do I now generate a new one that goes with my new "normal" password Thanks in advance for any help

Xfinity email service required me to change my password (security issue?). I went through the process but when I attempted to change my password in TB, it required me to change both the imap and smtp servers separately.

Apparently this is normal for TB. But this is radically different from other email systems. Most allow me to change the password once and it propagates to both the imap and smtp servers.

Am I missing something. If not, why does TB do it this way? This is extremely frustrating and unexpected for many people, I would think.

Oh, this is especially frustrating because I'm in a situation where two of my three Xfinity email accounts are repeatedly requiring a password change. I'm still trying to get to the bottom of that with Comcast.
