Thunderbird Community Forum

I was able to send emails to all of my contacts until a week ago when two contacts at USCG.mil have been rejected. I have reset the computer, manually loaded the addresses, tested other address and everything appears fine, but not to them. Any suggestions?

I switched to another mailing provider and before this I made an export of the mailbox. The Imap account was deleted at the provide, so my mailbox is lost. Now I tried to import the mailbox again, but the import fails.

I tried the import manager, but every time after import only empty local map are left. After this I tried the different options (profile of files), both gives the same results, showing an empty map. Then I tried the addon ImportExportTools NG 14.1.2. During the import TB shuts down. When TB starts after the import, for about 10 secs it shows the mailbox with the imported mails. Then unfortunaly all the email dissapears. Could anyone help me with this issue?

Thanks!

Email errors started occurring on or about November 25, 2024. Multiple calls and tech support with Spectrum techs and hours of troubleshooting brought about O results. I obtained all necessary protocols for configuring email to Spectrum requirements and for sending and receiving, but I still get outgoing errors. I have been using Thunderbird for 5 years or more now and never had any issues until now. Upon inspection through Thunderbird tools/setting/ looking at "SAVED" passwords, I no longer see "IMAP" or "MAIL" access protocols. It was there previously. I also disabled all my firewall and vpn settings and still cannot send out any emails. I have thoroughly checked out both my personal email setting and my small business email settings and everything as it relates to Spectrum is correct. Spectrum said one thing they found was that the email settings (specifically, would not resolve with the server because of a syncing problem). Spectrum did all they could to resolve on their end, but the issues, as they see it now resides on the Thunderbird side. In an effort to resolve the issues, the Spectrum tech looked and looked for a phone number for Thunderbird and said this is the first time he has never found a number that one can call for some sort of assistance. Emails directly to Thunderbird are very, very slow. And to compound the issue, there are no lists I could find is a repository for error codes and no valuable tech support or specifications could be found that provides any real help for resolution. So now I am making a last ditch effort to contact Thunderbird for a one on one phone conversation that will resolve all the issues I have encountered. Hopefully with your immediate reply, we can resolve these issues and I will be able to help others resolve these same issues. These issues are not just isolated to me. There are literally hundreds maybe even thousands of people out there with the same issues. PLEASE contact me asap. Thank you for your time. (PS. I do receive some messages via email, but sending out is the issue)

Just started using Thunderbird Mobile. On my desktop, I have checked the leave messages on server until I delete them box. However, if I bring in email on the mobile app, it deletes everything from the server. Is there any way around this?

I can go direct to web.com and use password and it works but Thunderbird says it is not correct. This happened after an update installed today.

My thunderbird recently crashed and stopped working (windows version 11 Pro Version 23H2) . The program seemed to freeze and after I got it closed it is not opening back up. I tried closing all of the background processes through the task manager and when I tried to open it again it will open a blank window, list it as not responding, and then close the interface with no ability to do anything beforehand. Tried using the repair option in settings, same response. Tried to reset the app, same result. Tried uninstalling version 128.1 and then installing version 128.5, no errors reported on uninstall or new version install but it still just opens a blank screen, says the program is not responding, and closes the window without anything else appearing. I tried restarting the computer (soft and hard restart) and get the same response. I need to be able to use my inbox manager or I need to move to another program. Thanks.

Hello the team,

Since your last update, sending message by Thunderbird is problematic. When checking, the menu flashes quickly, out of all control. Impossible to cancel, send, correct. You can absolutely do nothing. After a while (2-3 minutes of this flashing and it's long...) The message is sent. Before updating, this problem did not exist. Please do the necessary to remedy this bug. Thank you for your help.

Thunderbird recent Nebula esr updates have failed. So I have downloaded latest updates and reinstalled with same selections. Update history shows no updates installed yet!

Since latest Version 128.4.4esr Build ID 20241118214310 email access does not work after initial open or log on Startup. Get New messages All accounts or each Account show no activity. I now need to quit/reopen again to start receiving messages, then all continues well until another update or log off! It often takes a day before I notice no emails then I get 100+!

Mozilla Thunderbird installed on Win 11. Was working yesterday. Has been working for years. Now get error messages:

"Login to server mail.gmx.com with username macilray@gmx.co.uk failed. Sending of the message failed. Unable to authenticate to Outgoing server (SMTP) . Please check the password and verify the 'Authentication method' in 'Account Settings | Outgoing server (SMTP)"

Incoming messages are OK (I can receive messages). Authentication method is Normal Password. Tried changing password. Tried uninstalling and reinstalling. Same result. Same account works perfectly well on iPad. Online version at https://www.gmx.co.uk/ works perfectly well send/receive.

I have had an update to my hp laptop and now find that my thunderbird email on my laptop and phone are asking for a password. This has not been the case in the past. Would you please help me resolve this issue? Thanks

Hello from Belgium,

I use Thunderbird with my Hotmail mailbox. Sometimes the body of a message is missing. I just have a serial number like this "--0000000000003fb6ca0619db6a84--" When I connect directly to Hotmail via the web. I can see the body. Curious, isn't it ??

Received the following when trying to send an email

Sending of email failed. An error occurred while sending mail. The mail server responded: Too many messages (2.3.2.3) from 2.95.334.23. Please check the message and try again.

Incoming emails show at the bottom of the Inbox instead of the top. If I click on another folder then click on Inbox it shows at the top like it should. It wasn't always like this, how can I fix this?

All mailboxes erroneously show "no messages found"

You can go though the entire list on the left and all come up with the "no messages found" screen. The only solution is to restart/

This occurs after it has been working fine for hours, often after moving one of a few messages out of Inbox.

Performance was already poor in v115, but has gotten much worse since upgrading to 128.5. This is a documented bug: https://bugzilla.mozilla.org/show_bug.cgi?id=1906482 Are there any known workarounds? If not, how can I downgrade with losing all of my settings? I have 7 e-mail accounts and a few calendar accounts set up. This took a lot of time, since several of them require app-specific passwords. Thunderbird complains if I try to open a profile from a newer version in an older version of the software. How can I do this safely?

I use Thunderbird for email, when on MX Linux I use the Flatpack version. I've noticed that the Thunderbird configuration frequently resets itself, from using local folders on an adjacent disk, to a location within the Flatpack.

I know when this happens because I can then no longer send emails; I have to copy any text written, enter setup, re-select the desired folder, and re-start Thunderbird.

Can you please help with a fix for this issue?

Best regards,

Richard Palmer
