Thunderbird: форум сообщества

I have been trying to find an help email address for Thunderbird, as my copy has changed the layout of my screen and dropped the email display window that normally displays the email I select BELOW the email list in a SPLIT SCREEN mode.

Thunderbird will not download mail. It sends this: "The certificate for inbound.att.net does not come from a trusted source." "Location: inbound.att.net:995" Then it sends the data with the certificate information. I am not a programmer, I do not understand what I am supposed to do to get it going again.

Mozilla Account works normally directly inside Firefox, but logging into Mozilla Accounts through Thunderbird's Add-ons manager fails during the Firefox handoff.

Steps to reproduce: 1. In Thunderbird Add-ons, click Log in. 2. Thunderbird redirects to Firefox, showing "Continue with Mozilla account". 3. Click Continue -> Firefox displays "You could not be logged in. Please try again."

Troubleshooting already tried:

• Created a brand-new Thunderbird profile (thunderbird -P) — same failure occurs.
• Cleared cookies/site data in Thunderbird and cleared Firefox cache.
• Disconnected existing Thunderbird/Add-ons connections from Mozilla Account dashboard.
• Extensions and add-ons themselves install and download normally.

Just checked email this morning and my sbcglobal.net account is not connecting in Thunderbird. I hit get messages and it only connects to my gmail account. It connected just fine yesterday, and I did not change anything on my PC or in Thunderbird, so I ruled that out. I have since tried several suggestions from the internet, google, and Mozilla websites. I do not have a VPN and no changes to firewall settings either. I tried setting it up with IMAP settings and with POP3 settings and always get the same error. (attached pic) Also used my saved password for the account which did not work, and then tried the ATT secure key code which did not work. I deleted the entire account and tried to set it up from scratch but that did not work either. Looking for any other suggestions to get this solved. Thanks!

Suddenly, the comments in the descriptions of calendaring are showing up black writing in a black area, so I can hardly read them. Why? Was this changed in a recent update. If so, how can I fix it?

I recently set up Thunderbird for Windows as a troubleshooting step for my Yahoo Mail account which has been generating an incessant number of authentication pop-ups in Microsoft Outlook (Classic) for Windows. I had been using New Outlook for many months before switching to Classic Outlook a couple of weeks ago. With New Outlook, there had been no authentication issues nor pop-ups appearing. I have been using the OAuth authentication, not app passwords, in all cases.

Setup within Thunderbird was relatively easy and the OAuth authentication went through without issues. The account has synchronized and seems to be continuing to do so as I read, delete, and send messages.

However, when I went in to the Activity Manager, I'm seeing a number of errors, appearing every 10-15 minutes or so. They read as follows:

• Alert from account xxx@yahoo.com: AUTHENTICATE Server error - Please try again later

• The current operation on 'Inbox' did not succeed. The mail server for account xxx@yahoo.com responded: UID FETCH completed.

• The current operation on 'Inbox' did not succeed. The mail server for account xxx@yahoo.com responded: p.

Can anyone help me understand what they mean? It would help me stabilize Thunderbird and might give some clues as to what is happening in Outlook Classic for me. It would seem some have authentication issues with Yahoo on different platforms while the service works perfectly fine for others. I would like to move away from Yahoo as I find it finicky with a number of its features, but I'm a long-term user (25+ years) and don't see that being a practical solution at the moment.

Thanks!

I use Thunderbird for email. Suddenly I can neither attach nor insert files/photos into an outgoing email. Also, keyboard shortcut ctrl+shift+A doesn't work and is greyed out. I have no extensions and troubleshooting mode doesn't work either. What's wrong?

I have lost mt SEND button when I want to send emails to others. This has resulted some time ago and is most inconvenient when replying to email's. How do I get it back?

Have been receiving alert notification that my hawaiiantel..net account is temporarily unavailable. My email messages to that account are not being received and I'm unable to move email messages to the inbox of that account. Have been receiving these alerts for the past 3-4 days. is there a way to resolve this problem?

I have had messages about EWS support being ended from 1st October from the Beonex ExQuilla Add-On which I have been using for many years.

So I installed Beonex's new Owl Add-On which supports Microsoft Graph Protocol and migrated my Email accounts. However, this just renamed my existing account with "Old" at the end and created new ones which cannot connect!

The IT provider for the Email Domain will not allow the Owl Beonex App to connect, despite the ExQuilla one being used for many years!

They have now pointed out that Thunderbird natively supports the Microsoft Graph Protocol from Release 154. BUT I am on the ESR channel (as I need stable Email handling) and the latest ESR Release is 153.4.0esr!

So when will an ESR be released with Graph Support, as Microsoft could stop me being able to receive and send Emails any day as it is now past 1st October???? - Please let me know your timeline for the next ESR with Graph support A.S.A.P.

I do not want to install a non-ESR as I see that the latest Release 157.0.1 fixed a bug with the Graph protocol and 155.0 streamlined the manual account configuration. So I want stick with stable releases!

Also, do I have to add new accounts to use Microsoft Graph, or can I just change the configuration of my existing ones?

If the former, then I guess once I am happy I have all old Emails available (as I rely on Emails going back many years!), I can delete the original Accounts from Thunderbird, including the non-working " Old" ones created by the ExQuilla to Owl migration????

Thanks

My inbox appears empty. On the inbox setting it is only giving instruction to set up another account. My normal emails have disappeared. I can still see the emails on my phone however.

Greetings,

I've lost the ability to receive e-mail, Suddenly Thunderbird just quits on me with no warning. Apparently I can still send mail but cannot receive. This is the second time this has happened to me in as many months. How do I fix it? How do I prevent it?

Thanx

Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) mail.twc.com timed out. Try again.

AVG sends message: "We've identified a site certificate problem" "Trust for this certificate has been revoked."

Looking at certificate page that AVG provides is Greek to me. General tab displays:

"This certificate has been revoked by its certification authority"

issued to : inbound.att.net

issued by: Digicert Global G2 TLS RSA SHA256 20250 CA1

Valid from: 4/12/26 to 10/28/26

Details tab:

lists a bunch of things that I don't comprehend and offers an option to "copy to file" and lists a number of formats to copy the file to.  Have no idea which would be the one to use. 

Trying to access email directly from browser has not been successful because it wants verify my identity by sending message to my phone, but it does not send anything.

Hi All,

I am on the latest release 156.0 on Windows 10. I have 3 email accounts, 2 gmail and 1 yahoo. The Yahoo account has been giving me problems since the last 2 weeks. Mind that yesterday I have a completely new Windows 10 installation so also TB installation is new.

I have renewed the Oath login, all messages were downloaded without a problem, but once in a while I get different notifications about server errors such as the ones below. There's also a third type of message error but haven't been able to get a screenshot of it.

Could someone please help me to solve this issue? I really don't understand why the problem is intermittent. Thanks in advance!

New mail keeps going to either the Inbox, Notifications, or the Newsletter folders by default. No filters have been added to change the initial settings. How can the settings be modified so that all incoming mail goes to the inbox, eliminating every future instance of it being directed elsewhere?

I have no interest in the Notifications or Newsletter folders. I'm happy with getting rid of them completely, if that is a possibility that can solve the problem.

I tried turning off the add-on and turned off dark mode. I have been successfully using it this way, having to change the font color using font/bkgrnd color control. I have not updated win10 or TB since the last time I used this function. I send out daily emails with findings to a group bcc list. Not complex nor variating.

I went to light mode, turned off JonathanKamen's "Send Later" add-on (which is designed and executes well). Process successfully concluded.

Turned back on "Send Later". Still works.

I prefer dark mode. Documenting for advice and to see proactively if some gap is there in code say for error handling.
