Four accounts: Rogers Yahoo, Office365, GMX, and a second Yahoo account

When Thunderbird recently asked to access to my provider's server, I gave my Rogers Yahoo account and password; everything looked fine. But when I tried to use my second Yahoo email account, all the folders contained the same data as the Rogers Yahoo account, even though the email addresses were different; my original emails were gone from the Inbox and other folders.

So I began to follow the instructions in Mozilla's page "OAuth2 Authentication for Yahoo, AOL and ATT". 1) with Config Editor, changed "mailnews.oauth.usePrivateBrowser" to TRUE 2) checked for "Accept cookies from sites" in Privacy & Security settings 3) checked authentication settings: All Outgoing servers were set to "OAuth2", as well as Yahoo and Office365 incoming servers. The GMX incoming server was set at "Normal Password" with no option for "OAuth2". 4) I am in Canada and do not use VPN. 5) Finally, I deleted the second Yahoo account (tc2002ca) and all its data from Thunderbird. I logged into Yahoo! Mail online to make sure I had the correct password. I then added tc2002ca as a new account using manual configuration. I entered all the settings to match the Rogers Yahoo account, except (of course) the password which was associated with the tc2002ca account. The result: same as before - all the folders of this account were identical to the Rogers Yahoo account.

To summarize, all the settings in the two Yahoo accounts were the same (imap.mail.yahoo.com and smtp.mail.yahoo.com) except the passwords. When I "tested connection to server" in each case it came back "Successful". Please help me get back to having two Yahoo accounts in Thunderbird, as I have had for years. By the way, I have had no problem using SeaMonkey in a similar way. Thanks!

Hi,

I configured my account using the server's IMAP service. Every time I open Thunderbird, it asks me for the password of the calendar service of that IMAP service. But it doesn't have a calendar service. Even if it has, I don't want to use it.

I looked everywhere in the settings page, but could not find a way to disable it.

Why the app keeps asking me for the calendar service's password and how to disable it?


Thanks.

I just updated from TB 142.0 to 148.0.1. After the update, my Yahoo and AOL accounts display a login window and prompted to re-enter the login credentials. After I enter the email address and click 'Next' an error is displayed:

Edge: Too Many Requests

This appears to be a browser error. What is needed to fix this? I am unable to re-enable my email addresses.

When I tried to copy the link to a 'real' browser window I was able to get the verification code from the sites, but then got the error Can't reach this page at 127.0.0.1, connection refused which, of course, is the loopback address.

TB on Windows

Prior to TB 148, OAUTH worked for POP3 access to: Gmail, MS Outlook, and Yahoo.

After TB 148 upgrade: OAUTH to Yahoo fails, subsequent log-in page also fails. Both OAUTH to Gmail and OAUTH to MS Outlook still work fine.

Rolled-back/Reverted to TB 147.0.2 -- OAUTH to all works fine, as it did previously.

Note: YahooMail seems to have other problems. But I was able to confirm successful OAUTH and POP3 to YahooMail after reversion to 147.0.2.

I've always experience occasional TB crashes. According to my log history there was 1 in July, 3 in Aug, 2 in Sep, 2 in Oct, and 6 in Nov. I never really paid attention since the reboot was quick. But now in December I am losing work and it is a major problem. I've had 30 crashes in Dec and 21 in the past week. I have only 3 add ons and they have not changed, and a Copernic connector. I disable the Copernic connector and it didn't help. I have the same 140.6 on my Surface Go with the same add ons, except for Copernic and it runs fine. On both PCs I use Malewarebytes and WinDef. I have put exclusions for them in their setups. Even with MBAM completely disabled I've still had crashes.

I cleared the Cache and no help. I've even had occasional crashes in Troubleshooting mode. Here are my last 5 crash IDs

bp-070bf941-4e8b-41a3-8b84-3e3440251224 bp-a936f7c2-9ee3-4c38-b304-dab830251224 bp-8be9cf9e-8f2f-49bb-95cf-47e780251224 bp-12f8fc2c-c505-40f0-8c67-44b730251224 bp-9013fb78-086c-4327-9de8-62db30251223

Interestingly I’m also experiencing crashes with Firefox, especially ChatGPT. I cleared the ChatGPT history and that helped but did not solve the problem. I cleared the Firefox cache and in troubleshoot mode still have issues.

Otherwise my win11 PC seems to be working fine. I’ve run chkdsk and all is ok. Also scannow is ok.

Is my next step a profile rebuild?

This is true for two different user accounts on the same computer.

Thunderbird can't be exited without killing from the task manager or shutting down.
