I am trying to move emails from account "hasche@bigpond.net.au" to account hoedkaas@gmail.com. I was able to do this in a earlier version of Thunderbird. What has changed.

After a reboot and Windows 11 update today, Thunderbird (I believe it was v155) will not open. It asks for the password, then sits at [Not Responding].

I have copied my profiles (there are two, one dated 2023 with only a 1K .json file in it, and one created tonight while I was troubleshooting that's several GB and when copying, appears to contain all my mail folders although I can't access them directly from within the profile) to a separate location (my desktop).

I've tried the following (after checking previous questions here in Mozilla support):

(1) booting Windows into safe mode

(2) opening Thunderbird in Troubleshooting mode (Shift while opening), both in Windows safe mode and normal boot

(3) uninstalled Thunderbird from Control Panel, downloaded and installed a new copy of Thunderbird

All give the same result: "not responding", can't click anything. Can only wait or close.

I was able to disable an extension that I installed yesterday that had been working fine.

I'm also wondering if the problem is mail folders that are too large. I have some candidates for deletion but since I can't see any .msf files for them, I can't delete (because I can't open Thunderbird.

I'm leery of instructions to outright delete any Thunderbird folders/files because (1) I can't see my mail folders directly and (2) I'm self-employed and all my client and business emails are in there. Losing them woud be a disaster.

I'm tempted to try the Windows option of restoring my entire computer to an earlier point, say, this morning. But that seems like possible overkill if it's an issue with just Thunderbird.

I'm freaking out, please help!

When I open Thunderbird it is sending my emails directly to the deleted folder. I have tried all-sorts and cannot find an answer. I transferred Thunderbird to my new PC and all was working okay for a few weeks then all of a sudden there were emails missing from my inboxes and I found them in the deleted folder. I am 76 years old and need an easy step by step solution please ..... John

Thunderbird not connecting to server. It says timds out and an error occurred connecting to mobile.charter.net. I can neither send or receive emails. This started 8/20/2026

bonjour, J'ai installé un nouveau profil, mais j'arrive pas a utiliser l'icone -sélectionner messages à droite au dessus des mails- appliquer ces paramètres/la vue... Ca me serai utile pour simplifier et unifier mes affichages. Actuellement j'observe aucune changement, bug ou erreur de manip.

Since this morning there is no sign of my emails accounts and majority of functions appear disabled, it never happened before. Can somebody explain what happened?

Please check the image attached

Good afternoon

I have been struggling to find some messages specific to specific dates and spend an awful amount of time tryomh yo access the correct one.

The solution proposed is a bit unclear to me, as it refers to "future folders". I need to unthread all my messages. Is this possible?

Thanks

PS The only version number i could find was for Firefox. There does not seem to be one for Thunderbird.

Thunderbird has stopped getting messages and 'get messages' doesn't work & I have to close & restart thunderbird to receive them. Nothing has changed with the email client itself.

I know messages have arrived by checking my providers phone app, but for Thunderbird to download them to my PC I now have to restart Thunderbird to get new messages

Recently purchased a new HP laptop. And installed my ZoneAlarm without issue. Then downloaded Thunderbird and installed it. On opening ZA went berserk constantly alerting every few seconds saying there was a Bot. See attached screenshot from the last instance of this. Deleted Thunderbird and the problem disappeared. Was the problem actually caused by Thunderbird and have you any idea what was trying to access the website in the screenshot and what the website is that it was trying to access?

I don't know if this is the correct topic to select but there is nothing more relevant.I am using windows 11 and When I try to delete e mails (G mail) I click on the e mail and then delete. The e mail then disappears and I then quit out of e mails. However the next time i go into my e mails it is back again. The only way i can get them to delete is to again tick the e mail i want to delete and then click delete. If I then go into something else e.g. drafts or spam and then quit out of the e mails when i go back in the e mail i wanted to delete has gone. I have tried resetting firefox but makes no difference

I am trying to add IdeasDale@zohomail.com to my Thunderbird email. It is set as Incoming – imap -- Port: - 993 Server: - imap.zoho.com Outgoing – smtp –- Port: - 465 Server: - smtp.zoho.com

I have what should be a pretty simple question. 1. I deleted my Tbird POP acct because it stopped working. 2. I reinstalled it. 3. My saved mail folders were gone. 4. Is it possible to get them back? 5. * This question is for someone other than David. 6. I just want to get my old saved folders back into my reinstalled account. 7. It's been about five days since this all took place. 8.The version I deleted was a the previous release.

My email was working then suddenly stopped. I have been connected to AT&T (Currently and Yahoo). I finally got it touch with AT&T mail. They claim that they no longer support or connect with Thunderbird.

Does anyone know if this is this correct?

Thank you for any help!

Or does anyone have any suggestions on what may have happened. This started one or two days ago from 09/09/2026

When are you finally fixing the exponentially raising problems to work with Thunderbird and Gmail? It is getting totally out of hand! Since my upgrade to the latest version NOTHING works anymore!

After stating TB the imap.gmail.com is running forever, freezing TB up. After ending the hung up programs 5 TB processes remain. Even after trying to kill them in the taskmgr, one remains active forever, is NOT kill-able anymore, and PC needs to be rebootet. End of story!

TB become a HORRIBLE Disaster!

I have Win11, Thunderbird Windows MSIX packagethunderbird-MSIX - 1.0, and several accounts (The box below won't take anything past "Thunderbird Window.")

I'm looking for some way to make a different ring either for one of the accounts or for certain domains or for a subfolder -- any way that I'll know when something comes in from specific domains. The special ring(s) can be for each of the two domains or both of them. Can that be done?

154.0 (64-bit) on Windows 11

My filters are broken in Thunderbird. I have deleted and recreated some to no avail.

I moved some folders from Local to under my inbox and it said it would update the filters automatically, but noticed it didn't do this. Looking at the Filter Rules it just left either the first or second column of Perform these actions under the Filter Rules empty rather than updating them. I tried moving the folders back to see if the filters would then work, but it's a mixed bag. Some filter properly and others only go under say Newsletters, but don't filter into Newsletters > Adobe for example. Others just sit in the inbox. I've tried moving some rules to the top of the list hoping that'd give them priority to be run first, but it hasn't helped. I have a lot of filters setup to help me track newsletters, classes, meetings, job applications, etc. I've missed some responses for a couple of days because of this. Any suggestions?

So I don't miss anyone, thanks in advance.

I have many years and email accounts on my old WIN10 workstation running all POP installations.

I have a new workstation with WIN11. Is it possible to install TB on my new workstation with my accounts installed as IMAP and keep the same folder configuration? I have many email folders and filters setup on the old workstation installation.

I would appreciate any installation recommendations. I've been using TB for years and would like to keep as much of the current configuration as possible.

For the first time today I have been unable to send emails from any of my Microsoft accounts - I tried 3 of them.

gmail required me to sign in - but won't accept the UK phone number I entered to verify my account! My TalkTalk email - which I don't normally use - did 'nothing', but I didn't have a pop up message.

I don't think I'm receiving emails for any of my accounts either.

The first message attached has 'popped up' every time I opened Thunderbird Mail for some time, but it did not affect sending or receiving emails.

I saw something new to me under Programs and Features and have attached a screenshot of that, along with full details of my Thunderbird version.

Help, please!

I'm using Thunderbird 115.18.0 and just today it's behaving bizarrely. Crashed twice for no reason, and emails are taking "forever" to delete -- normally they delete immediately (unless they have an enormous attachment), but today I have to wait about 4 seconds for one short text only email to delete. Compacted folders, and made no difference.

Any ideas? Anything I can do to return to my normal I love Thunderbird condition?

Thanks.
