I-Thunderbird Isithangami Sokwesekwa

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="

For some reason, whenever I have multiple tabs open in Thunderbird, it will seemingly randomly open a new window, interrupting whatever I'm doing. What seems to happen is that the new window will contain the tab I was working with (address book, settings, etc.) and a tab for my mail, but that mail tab will have switched to a different mailbox. And then the new window that opened behind the other one will have a tab for my mail focusing on whichever mailbox was selected before.

This is driving me absolutely crazy! It keeps interrupting what I'm doing and makes me anxious to do anything in any tabs in Thunderbird. I need to fix it!

Any idea why this is happening and what I can do to stop it?

I have 4 different gmail accounts that I use thunderbird to manage, along with local folders. Starting today, I cannot send messages. I get a dialog box with no error codes, underneath is another dialog box showing send progress with the eternal circle. Have rebooted, made sure each account has a unique SMTP server description. Worked fine until today. No updates that I know of.

I have to manage a number of joint email addresses which are outlook.com addresses, so I have them all installed on Thunderbird.

Up until recently, it worked fine, although every few months Outlook.com would not allow the sync because of some security issue (wanting an alternative email address, wanting an alternative phone number, wanting me to confirm that the last sync was me). I would sign in to the email account on a browser, fix the issue, and then it would work again.

As of a few days ago, Thunderbird is showing the "Login to account XXX failed" and "Login to server outlook.office365.com with username XXX failed" for maybe a dozen of the addresses every time I open Thunderbird. If I login to the email on a browser, and force Thunderbird to "Retry" several times, it will sync the account - but the next day, the same issue arises with the same account. When I check the account activity, it shows successful automatic syncs.

Is there another setting I need to check or change to make Thunderbird work with Outlook.com addresses?

I am using Thunderbird v 115.5.1 on a Windows 10 system. I am using an "@hotmail.com" email address. I seem to be able to receive emails just fine, but face an issue sending out emails. When I press "send", it gets stuck on "sending message" for quite a while, then I see the error message:

=

Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) smtp.office365.com timed out. Try again.

=

My SMTP settings: Server Name: smtp.office365.com Port: 587 Connection Security: STARTTLS Authentication Method: OAuth2

Appreciate any help! :)

Since the latest thunderbird update 115 I have multiple crashes & black screens, before this it was very stable. I have been using this since 2015 I think with little problem until now. If nobody else is having problems with 115 perhaps I should just use windows restore to go back to Dec 10th 2023. The only alteration to settings I made to try and fix it was to untick "use hardware acceleration when available". It made no difference.

Hello, After update Thunderbird quick filter became very very slow.

If you type in quick filter field two words. At the beginning is being shown random results not connected with typed in words. Then in 30 seconds or later are being loaded correct results. Not possible to use like this. It's local search on normal PC (with CPU AMD Ryzen 5 PRO 4650G, 24GB RAM) filtering must to work fast. Could you fix that issue?

Thank you

greetings to the forum. TB 115.7.0 (64 bit) on windows 10, 32 GB RAM, intel i7-6700 CPU@3.40GHz I signed up for an account on the newsserver astraweb.com which has a very high message retention, around 21 years in the groups I subscribed to!!! in two groups I subscribed to, it downloaded 1410000 and 3031000 headers (no messages)... since after this massive download it was slow and unresponsive often, I repaired the folders of those groups and deleted the startup cache... in response the TB re-downloaded everything again, remained not responding for about 20 minutes and during this process used over 20 GB of RAM memory (see attached image). now it's using about 8.5 GB RAM, but every time I click on one group or another of astraweb it freezes with a "not responding" message until some mysterious task finishes... I could try to limit the number of headers downloaded in the account settings but I will only do it if I have to... If I don't find some solution, this way TB is almost unusable...

before posting on bugzilla and before deleting the older headers, do you think there is anything else I can do to avoid freezing TB on that server?

Suddenly today Thunderbird won't access either of our Hotmail accounts. Error message reads "Login to server imap-mail.outlook.com with username my.name@hotmail.com failed." After several prompts to Retry/Enter New Password/Cancel, I even put the correct password in with no success and eventually received another message "Server has disconnected. The server may have gone down or there may be a network problem." Neither of these are true: I can access the server on my browser so I know the password is correct. Both my late husband's and my hotmail accounts are affected this way. Help! I am nearly 80 and not terribly computer literate and somebody else set Thunderbird up for me years ago because I wanted to be able to archive my messages locally (offline) and now it's suddenly stopped working.

Since the dawn of time, the Compact folder command on the folder context menu has compacted just the selected folder. However, I have noticed that in the latest Thunderbird version (I'm using 115.6.1) the Compact folder starts automatically compacting all subfolders under the current one. This is a big problem for me: under the inbox, which I need to compact fairly often because all messages pass through it, I have literally hundreds of subfolders, some of them dating from more than 20 years ago, when I used Netscape Communicator. Those folders are "read only" (I only have them for reference), and I do not want to modify them in any way, to avoid risking their contents. Thus, I DO NEED for Thunderbird to stop compacting subfolders automatically. Is it possible? How can it be done?

Also, after a folder compacting has started, what's the best way of cancelling it, short of closing Thunderbird? I understand that the compaction process is quite safe, as it copies all data to a fresh file, but would rather not risk data loss.

Hi, my mailbox on the server is set to 5Gb. However the size of the IMAP directory of this mailbox on my hard disc is almost 22Gb. Sometimes I occured the situation that the mailbox's size on server lik 500Mb the IMAP catalogue took 80Gb of disk space. What might be the reason. Using 'cleaning' option does not help. Any thoughts? Mirek

I've been through all related articles in this forum to try to resolve this issue, as the popup keeps popping up.

This is what I've checked and did; 1- Checked Outgoing server (SMTP) settings - No trace of account there. 2- Produced a 'Troubleshooting Information" report; Nothing under 'Mail and News Accounts' 3- I've deleted my Calendar and made a new one. 4- Got HostGator on the phone and they confirm that my account is close and files deleted.

And it is still not resolved. Anyone knows how to resolve this issue ? Thanks

I am asked to get a new password from my mail server (AOL) every day when trying to send messages. Have to log on to AOL, ask for app password, enter at Thunderbird. DAILY!

Excuse my basic tech knowledge....

Thunderbird is clogging up my drive with over 200gb of files and now I am getting constant messages about not being able to get emails because of a lack of disk space.

My xul.dll file is 121 GB and my omni.ja file is 80 GB.

I have multiple nstmp folders (x15 at last count) that seem to be the problem.

Every time I try to delete them though, I am getting a blue screen computer crash...... even in safe mode.

How can I delete those files manually?

If I reinstall Thunderbird, won't it just keep all my files/folders which won't solve my problem?

For the last few weeks, I have had a strange problem with Thunderbird. I receive an email that shows in the email list with the subject, from, and date of the real email. However, the body of the email is from some other email, and corrupted at that. I showed one jpg that shows the email listing, and 3 jpgs that capture how the first part of the email appears in Thunderbird. Even though I don't have the headers expanded, I see detailed header-type information. I captured down to where the body of the message starts in case something in all that apparent expanded header provides a clue. When I look at the email on my Google web account, it is fine. It only shows this way in Thunderbird. It has only happened about 3 times in the last 2-3 weeks. The body I see, by the way, seems to be the same every time. I am hoping someone has some ideas.

In most cases, it has been an email I did not really need anyway, so I just deleted it. One was a needed email, so I opened it in the Google web interface and forwarded it to a different account, where it showed fine.

Thanks again for any advice. I am currently using TB 115.6.0 in Windows 10. However, it has happened on the earlier versions I had over those past couple of weeks.

I made a backup of the email, but now when I try to restore the backup, it gives me the error "Unable to open the summary file for Inbox on email@example.com. Perhaps there was an error on disk, or the full path is too long."

I did the repair folder but the error shows up again, I reinstalled thunderbird, the error is the same again.

Can someone tell me how to do a restore backup?

Thanks
