My old provider has stopped supporting my old email address and I have changed to a gmail address. How do I remove the IMAP and smtp settings etc for my old email address? Also remove all trace of that unwanted old address please?

Using Thunderbird with Spectrum email (an old roadrunner address). Changed the outgoing server to the following: Server Name: mobile.charter.net Port: 587 Username: Reefside@cfl.rr.com Authentication: Normal Password Connection Security: SSL/TLS Testing connection fails. I have tried different combinations and once in a while I get that the connection is successful, but email sending hangs and never completes.

Thunderbird aggregates in the same threads e-mails from my employer that are completely unrelated. They are sent in different months, with a different subject, etc. and they end up in the same thread. Clearly, there is something in the header pushing Thunderbird to aggregate them, but this results in a very annoying ordering of the emails.

In my case, e-mail messages are sorted on date with descending order. However, the first message I see in my list dates back to months ago because another message sent few days ago has been merged with the previous one in a thread.

This would not be a problem if the message displayed in the list were the last one added to the thread and not the first one starting the thread.

I have done several searches and read several help pages and discussions here, but I cannot find a way to display threads in the same way the rest of the messages is shown, i.e. latest first. For some obscure reasons, Thunderbird keeps displaying in the message list and in the threaded view (when I expand the thread), the messages in reverse order wrt my selection.

How can I fix this?

I've been a Thunderbird user for years without problem. However, since May 22, three specific messages continually reappear after deleting them from my Inbox.

I keep my Inbox empty and it stays that way, except for these 3 messages. Removing them from the Trash folder has not solved the problem.

My email provider is netaddress.com via POP3 account. I signed on to look at my inbox on their site via a browser, and the messages aren't there.

I have tried repairing and compacting the inbox, but the messages continue t reappear.

Do you have any other suggestions?

TIA.

I recently moved from Microsoft Outlook email to Apple icloud email. icloud allows you to create an application-specific password, which I did for email. It works; I can login to email on Thunderbird using my (impossible to remember long) password automatically generated by Apple. I switched the Thunderbird server settings to OAuth, but unlike with Outlook, there was no popup saying a restart of Tbird is required. When I quit Tbird and restarted, it did not prompt for a pw, but neither did it get any new messages. (I sent new messages from another email service to verify.)

I also noticed that OAuth2 was not an available option for the outgoing server, as it was with Outlook.

Does OAuth2 not work with icloud email?

There appears to be no way to change the app-specific icloud pw in Apple, but I will take that up with Apple.

Perhaps the workaround is to use the Tbird saved pw feature?

Subject: Persistent Column and Folder Layout Issues — Not Being Saved Between Sessions

This is a follow-up to my previous support requests regarding two ongoing problems that significantly impact daily usability.

Column Settings I manage multiple accounts, and my preferred column layout is: Starred, Read Status, Attachment, Subject, From, and Date/Time. I do not use Threads, Correspondents, or Spam Status columns. Despite setting these preferences repeatedly, Thunderbird fails to retain them. Every day I must spend time reconfiguring columns across some or all of my accounts — the state varies unpredictably from one session to the next. This is a persistent, daily frustration that costs meaningful time. Most other major email clients save and reliably maintain column preferences. I'd expect Thunderbird to do the same.

Folder Panel Layout Two problems occur regularly when Thunderbird loads:

Folder order — Standard system folders (Inbox, Sent, Drafts, All Mail, Trash, Spam) should appear at the top of each account. Instead, Sent, All Mail, Trash, and/or Spam are frequently scattered among custom folders, with no apparent consistency.

Folder expansion — Most or all folders load in an expanded state, exposing every nested sub-folder regardless of whether they contain unread mail. This creates unnecessary visual clutter and requires manual collapsing each session.

Again, this behavior is uncommon in other widely-used email clients. Summary These are not one-time glitches — they recur daily and represent a significant usability gap. I'd appreciate confirmation that these are known issues being tracked, or guidance on a reliable fix. Reformatting the interface every morning is not a reasonable expectation for users.

Can't get email from Comcast server any more & a lot of existing emails disappeared. Was on the phone with them & reset ports & checked other things but it didn't work. I can read them at Comcast's site & also send & get them there. Also can you help me forward my email to another email program?

Dear all,

For aprox. 3 weeks now Thunderbird asks me a short time after startup for a login.

It shows up a dialog with the text : "https://caldav.gmx.net verlangt einen Benutzernamen und ein Passwort."

The problem is, that I maintain several GMX - accounts and I've no idea, which credentials I have to enter :/

How can I find out ( without inspecting or debugging the source code ;-) )

THX in advance and best regards!

Today I created a subfolder and moved many precious e-mails there. That move was successful. Thereupon I shut down my Thunderbird and my computer. When I restarted my computer and my Thunderbird the folder which I created was empty. Please let me know how I can recover the e-mails. Thank you.

I have been using Thunderbird for years with no problems. However recently, Thunderbird very often simply stops responding. Sometimes it just hangs up and sometimes the program bar at the top displays "Mozilla Thunderbird (Not Responding)". If I try to wait for it to respond, it literally hangs for several minutes before it begins to respond again, and often, it simply never starts responding again. It has simply gotten to the point where Thunderbird is practically unusable. All my other application software continues to work with no problems. It's just Thumderbird.

The version number in this submission may not be correct. I can't provide the real version number because of the hangups.

Any suggestions?

Hi all,

I've been using Thunderbird for eons but yesterday morning it started freezing up constantly.

It freezes up ("Thunderbird is not responding") every time new emails are received or any time I take any action while the Inbox folder is open. So, if I delete an email it freezes for a few minutes. If I do anything pretty much, it freezes up for a few minutes. Then it comes back and I can do another action, and it freezes again. This only seems to be happening when I have the Inbox open - if I go to other folders it seems to function normally.

Things I've tried without success: - Troubleshooting mode - Adding exceptions for my profile folders to Windows Defender - Compressing Inbox (and Trash and Junk) - Repairing the Inbox index

This doesn't appear to be a memory issue - right now, memory use for my entire system seems to be hovering at just over 50%. But Thunderbird is still freezing.

My Inbox folder is very large, but it's never been an issue before and nothing significant was added yesterday when it started failing.

Any suggestions appreciated!

Thanks

I've been seeing a doubling of *some* incoming messages, where a duplicate message comes very soon after the first one. For example, two incoming messages were received at:

Sun, 07 Jun 2026 14:03:10 +0000

Sun, 07 Jun 2026 14:04:31 +0000

So the second message came in about 1 minute and 21 seconds after the first, and not because of anything I did (as far as I know). But then that was it, no third message came in.

This isn't really a bug, as nothing is harmed, just a repeated message. Any thoughts would be appreciated.

Thunderbird forces me to use the new amount hub. And I get authentication error when trying to setup outlook.com email

I transferred my Win 11 T-bird system to a new Win 11 computer using the T-Bird instructions re Profiles etc. The system transferred and operates on the new computer, BUT the last six years of e-mails and my current address book and calendar did not. The calendar that transferred was from 2014 to 2020 and the addresses were also from 2020. The current email addresses and up-to-date calendar didn't transfer. How can I make sure my current data transfers. I still have my old computer with T-Bird installed?

I would like a view by Year option in the Thunderbird Calendar. Since Microsoft Calendar tries to launch Outlook and setup a new email address when you try to use just the Calendar it has become not useful to someone who does not use Outlook. You can get the Calendar app to launch into the Calendar on the 4th try but it's inconsistent and a pain. I was trying to check a date/month by displaying the Year view with the 12 small monthly calendars like the Microsoft Calendar has and found you cannot do this. I'd prefer it as a feature rather than a plug-in. Thanks

Mozzilla fonctionne mais je ne peux plus faire "envoyer" mes mails. C'est terrible d'autant que n'y comprends rien . Je rédige-sur la page "Rédaction" et après il n'y a plus de case "Envoyer." par contre je reçois les mails J'ai glané les infos au bout de 2 jours  : IMAP Je sui "Orange" Sortant SMTP/SSL/TLS port 459 Entrant SMTP/SSL/TLS port 995 et quelque part  : version 140.II.Iesr  ? Vous pensez que c'est grave ? ça fait 10 ans que ça fonctionnait

I'm using gmail/outlook/hotmail email addresses on a new win11 laptop with Surfshark VPN and getting email up & running is the last major set up issue. I am having issues with both send & receive emails across all addresses. I get some functionality if I pause the VPN (not ideal!) but not total. I have tried the Surfshark bypass function for Thunderbird but without success.

I have had no issues with this setup for many years on win10.

Using Outlook (one email address) on the web with the Surfshark Chrome extension I can both send & receive.

1. what should the IMAP & SMTP server settings be for gmail/outlook/hotmail? 2. are there any known issues with Thunderbird/Surfshark? 3. are you aware of any issues with gmail/outlook/hotmail blocking Surfsahrk?
