Thunderbird Support Forum

I've been running Thunderbird for years on Gentoo which has version 115.10.1 as the most recent. I don't send much mail so I'm not exactly sure when this problem occurred, but I'm unable to authenticate with my SMTP server. I have not changed any configuration. Some weeks ago a changed my password on the server, but I made the appropriate changes to Thunderbird password manager. All settings, username and passwords are 100% correct as I copy pasted all of them. IMAP on the same server (uses same credentials) works.

I have tried deleting and re-adding my accounts which did not help. I have also tried deleting my profile folder. All other mail clients (e.g. claws-mail, kmail, mailspring) with the same SMTP server don't have any problems sending mail. This problem seems to only affect Thunderbird and Thunderbird forks such as Betterbird.

I have no firewall and am using SSL authentication with cleartext password on the SMTP server.

I get the following output to console on attempted sending of message:

console.error: (new Error("Server error 503 Service Unavailable", "resource://services-settings/Utils.sys.mjs", 390)) console.error: mailnews.smtp: "Command failed: 535 Incorrect authentication data; currentAction=_actionAUTHComplete" console.error: mailnews.smtp: "Authentication failed: Incorrect authentication data" console.error: mailnews.smtp: "Authentication failed: Incorrect authentication data" console.error: mailnews.send: "Sending failed; Unable to authenticate to Outgoing server (SMTP) mail.kapsi.fi. Please check the password and verify the 'Authentication method' in 'Account Settings | Outgoing server (SMTP)'., exitCode=2153066805, originalMsgURI="

My environment - I am running Thunderbird 115.10.2 (64-bit), and Windows 10. - I have had NO Windows updates for at least two weeks.

The problem - About five days ago, outgoing messages (messages I was trying to send) started taking about 15 to 30 seconds before they were sent successfully.

- Today, I am unable to send messages. I can receive messages.

Actions I have taken 1. I re-installed Thunderbird after using Revo Uninstaller to uninstall it. 2. I contacted my ISP. They checked their settings, and have been unable to detect any error.

Please help!

I just installed Thunderbird on a computer, current version, and it didn't update my address book or contact list off the server. How do I do this manually as I could not find something saying to "download contacts" or anything like that. There is the "Directory Server:" option but I don't know what that is or how to use it. I didn't do that on my other Thunderbird installation (Work Computer). My email server is Mail.com if that matters. Thanks

I recently moved to a new Windows machine and can not send mail from either hotmail or gmail accounts. I am able to send and receive from my account at outlook.office.com, but hotmail uses outlook.office365.com as the mail server.

Thunderbird Version: 115.10.0 Windows 11 Version: 23H2

The message I receive when trying to send is: Sending of the message failed peer's certificate has an invalid signature the configuration related to smtp.gmail.com must be corrected (also for smtp.office365.com)

I did try all of the fixes advised here, as the error message certainly matched what I was seeing: https://support.mozilla.org/en-US/questions/1295861 so my settings in TB are currently: security.tls.version.min = 1 security.tls.version.enable-deprecated = true

The final suggestion in the above thread was to move back to Thunderbird version 68.11.0, which I will try if nothing comes of this thread by the weekend.

When I'm searching Community Discussions, it would help a lot to be able to sort the discussions by date or at least see when a discussion was started without having to open each discussion individually. Is there a way to do this? The answers in older discussions, pertaining to older versions of Thunderbird/Firefox, may no longer apply and it is frustrating to try and find pertinent discussions when you have to open and close each discussion looking for answers.

In my attempt to help my wife with her email problems I have managed to totally screw up her profile. There now duplicate inboxes, duplicate local folders, duplicate Outlook Express Import files, etc.

Is it feasible to export/backup the inbox, address book, files&folders, Outlook Express Import files (but not the profile), then uninstall Thunderbird in order to start over? If so, how is the best way to do this?

She only has one email account on Thunderbird and is running Windows 10.

Thanks in advance for any help.

Somebody thought that it is a GREAT idea to make drag-n-drop cursor a GIANT rectanglular thumbnail of the emails being dragged.

No, this is a horrible idea because that thumbnail covers the target of the drag-and-drop.

Either REVERT this IMMEDIATELY or let us know how to disable and revert to the simple drag-n-drop mouse cursor that does not obstruct the target of the drag.

And in the future AVOID any GUI changes that are not ABSOLUTELY NECESSARY. With these poorly thought through, extremely annoying changes you are only causing damage and aggravation.

Over the last few weeks, emails have vanished from my inbox, as well as trash, templates and other mail boxes. In may cases, no emails are being displayed, when "total message count" shows messages are present. In other cases, several days of recent messages have disappeared.

I have tried "repair folders," deleting "smart mailboxes' and even deleting the .mlf file of one inbox without success.

I have 6 email accounts including 2 GMail. The problem is in all of them. As the screenshot shows, there is a disparity between total messages and displayed messages in all boxes (partial view of accounts).

V 115.9.0 (32-bit) Good day, I have K9 as my mail client on my Android phone. In K9 there is the possibility to display all incoming mails of my different IMAP accounts in one folder (Common inbox). Is it possible to set up such a folder in Supernova? Thanks for detailed instructions Stefan

Hi, I am running Thunderbird v. 115.9.0 on Windows 10 on my desktop. I have been forced by Rogers in Canada to migrate my internet service from their legacy internet service to Rogers Ignite with its Ignite (Comcast) gateway. My email accounts were supposed to be migrated automatically, but, for reasons unknown, were not, and a tech support representative had to migrate them from the old legacy service to Ignite. After that was done, I opened Thunderbird, and was asked to authenticate my 2 Rogers/Yahoo email accounts, one of which is my primary account, the other a secondary account. I was asked to authenticate the secondary account first, which went well. I then clicked on my primary account in the left-hand pane and was again asked to authenticate, but the dialogue box showed it was for the secondary account. Thinking that this secondary account authentication was just being repeated for no particular reason, and not thinking that the email address in the authentication request box could be changed, I clicked Agree. My primary account is now showing the exact same emails as are listed in the secondary account, and I'm extremely concerned that I will not be able to recover all of the thousands of emails in my primary account, many of which are business-related. When I log into my primary account on the Rogers/Yahoo mail website, the emails in the primary account are still showing, so I know they are still on the Rogers IMAP server. However, I really want to continue to use my primary account on Thunderbird. I'm not sure if I should delete the primary account and recreate it - the Rogers support tech said that deleting the account may result in an issue where my current password for a re-created primary account may not be recognized, so I'm leaving things as they are until I hear back. It the advice is to not delete and recreate the account, what steps can I take to recover the emails on my primary account in Thunderbird. Thanks in advance for any help and advice that can be provided. LES.

Please find attached screenshot. I have added 10 email accounts for 5 domains. Most of them are unified since I used the "unified [folders]" option. Unfortunately, Thunderbird ignores several email accounts. This seems like a bug to me.

from today I cannot download my gmail to Thunderbird, I'm getting always here below error code:

“400 invalid_request” or “Access blocked: App sent an invalid request,” it means the app uses an authorization method that Google doesn't allow. Google has safe ways for you to sign in and share your Google Account data with third-party apps and sites.

Please let me know how to proceed.

Thank you

115.05 when I started.

I typically open Thunderbird about once a month, download my emails from a hosted website, do some clean up, write some emails, close Thunderbird, and do the same about a month later.

Today I opened Thunderbird, saw that it was downloading around 400 emails in the lower left corner, and waited patiently, as per usual. When "done", however, none of them showed up in the main window. The latest email did not change, was still from around a month ago. When I ask Thunderbird to Get Messages it says there are no new emails to download.

I restarted Thunderbird several times, no change.

I then upgraded to 115.10, hoping this might fix the issue, but it has not.

Since restarting Thunderbird, 2 new emails have come in and are showing correctly, but none of the initial 400 emails "downloaded" today are showing anywhere.

I repaired the Inbox folder (right click > Properties > Repair Folder), no help. I renamed the "Inbox.msf" file and had Thunderbird rebuild it, no help. I renamed the "global-messages-db.sqlite" file and had Thunderbird rebuild it, no help. View Ignored Threads does not help. View > Threads > All is selected. Emails are not in the Trash folder, or any other folder.

All of the initial batch of 400 emails - and the emails I had previously opened - just disappeared.

Opening up the Inbox MBOX file directly, I can see that these 400 emails were never actually downloaded into this file. Not sure what happened.

Opening up my remote email host, I can see that those 400 emails are still there, to the exact point when I last closed Thunderbird.

Asking Thunderbird to download new messages does not download these remote emails.

How do I reset Thunderbird to start the process over and re-download these emails again? Part of TB seems to think it's already downloaded these emails, while another part of TB never actually did.

Does anyone have any idea what to do here?

Hi,

I have both gmail and btinternet accounts feeding in to Thunderbird. I can send emails from my bt account but not from my gmail account. When I try to send a gmail message a pop up informs me that the out going server for gmail has timed out. I have checked the server settings for gmail's out going server and it is set up as Thunderbird states but the problem persists.

Can anyone help to solve this problem please?

I have many email accounts I pickup with Thunderbird and I used to be able to sort them in order of importance but not so with v125.0.

The add-in is disabled and I tried sorting the accounts in account setting but the minute you leave account settings the sort is gone.

I saved a draft of a long email.

I now wish to open the draft to proof read it and send it.

With the latest version of Thunderbird I cannot find any way to access and open the save draft.

Any assistance gratefully received.

Thanks in advance

Peter

when I try to start Thunderbird, I get a window that says "Your computer must be restarted to complete a previous upgrade Thunderbird. Do you want to reboot now?. I've rebooted several times now, scanned with PC Matic, rebooted again, tried to uninstall in Control Panel, and get the same window. How do I fix this?

I removed an account (membershipsec.KLcommunitychoir@gmail.com) from Thunderbird but I am still being asked to validate my ID for that account every time I look at my email. It's a Google page that is displayed but it seems to be Thunderbird that is triggering it. How do I stop it?
