Every five minutes Mozilla sends me a page asking for access to my Google account. I click "deny" and it goes away for a few minutes, but comes right back. And while it is on, I can neither send nor receive email. Is there some way to get it to go away and stay away? Thanks, Larry Wright

All was well until about six months ago. When I try to connect to my provider TB won't connect. BUT. At other times it will connect then every few minutes will try to connect again - then again .... I get this message "Connection to the server mail.comcast.net timed out". Then I get this message each time it fails "Login to server mail.comcast.net with username 170834000 failed". It keeps asking me to input my password even though everything is working appropriately. Then at other times it says it doesn't connect but it has connected and it still continues to ask me for a password.

I have uninstalled TB and reinstalled it thinking that would fix it - it didn't. I have changed my password - again to no avail. I let TB choose where to put things and configure each item appropriately. I don't try to get in the way of what works.

Comcast is apparently getting out of the email business and asking everyone to move over to their chosen substitute (Yahoo.mail) and I have not chosen to migrate at this point. Maybe that's the problem. This is the message I get each time I log into Comcast.net:

"A better email experience is now available for you

You're invited to upgrade your email account to Yahoo Mail, so you can enjoy a more user-friendly experience. Your email address, messages, folders, and contacts will not change.

With Yahoo Mail, you'll enjoy enhanced security, a built-in calendar that's easy to use, AI-powered inbox organization, and a top-rated mobile app for easy access on the go."

I am not aware of any changes in the settings from before when it was working well and now when it seems to be erratic.

I am not terribly computer savvy, but I'm usually able to trouble shoot and fix the issues that confront me. This time I'm out of my league! I need help.

Thank you for helping me.

There was an earlier Case with the exact same name as what I named this case which was archived back in 2025. I have been living with this same problem since last year also. In the previous case there was reference to "downgrading" to an earlier version of TB, but there have been a bunch of updates since then so I doubt that would fix my problem because that earlier version is now over a year old.

I have one Gmail folder that correctly has one folder label "Junk." However, I have 4 folders that are AT&T related (2 from the domain "sbcglobal.net" and 2 from the "att.net.") For some reason when I set these folders up years ago they started out as labeled "Spam" instead of "Junk." Of those 4 folders 2 of them have the duplicated "Spam" folders, one from each domain."

When I go to Folder Properties I see "imap://XXXXX%40sbcglobal.net@imap.mail.att.net/Junk" on one of these Spam folders and "imap://XXXXX%40sbcglobal.net@imap.mail.att.net/Bulk" in the other. And the same "Bulk" vs "Junk" issue is in the other domain as well. All are named "Spam."

Can I simply delete one of these folders that are named "Spam" in each domain? Does it matter whether I delete the one ending in "Junk" or the one ending in "Bulk?"

Thanks.

just got Thunderbird, i added my outlook email then got to the "connect your email setting" then i clicked continue cause i wanted to use imap and got a "Authentication error". I got Thunderbird on a different device and used my gmail on that device and it worked fine. Only get the error when i try to use my outlook email and i don't know what to do.

Hello Thunderbird Support, I am experiencing a severe IMAP folder synchronization loop with my Yahoo Mail account (paulpersonne519@yahoo.fr) inside Thunderbird. Yahoo Support claims the issue is caused by Thunderbird's folder mapping, so I am reaching out to you for a solution.

1. 1. The Problem:

The system-protected folder "Bulk" (Spam) has somehow been moved or mapped as a subfolder inside the "Trash" folder.

• In the Yahoo Mail Web UI (Chrome), the subfolder is invisible, but the Trash directory shows an arrow (^) indicating a child folder exists.
• In Thunderbird, the Bulk folder is clearly visible inside the Trash folder, marked with the flame (Junk) icon.

1. 1. What goes wrong:

When I delete spam messages via Thunderbird, they get trapped inside this nested Trash/Bulk directory. If I try to delete or empty it, the emails disappear but the folder itself cannot be removed.

1. 1. Steps tried so far that failed:

  1. Attempting to delete or rename the Bulk folder inside Trash gives the server error: [CANNOT] DELETE failed - Mailbox is reserved.
  2. Using Shift + Delete on the folder is rejected by the Yahoo server.
  3. Unsubscribing from the folder via "Advanced IMAP settings" -> "Show only subscribed folders" fails; Thunderbird re-downloads the structure on the next sync.
  4. I have completely deleted my old Thunderbird profile folder and created a brand new one using thunderbird.exe -P. Upon adding the Yahoo account via OAuth2, Thunderbird immediately pulled the same broken Trash/Bulk structure from the server again.

Since Yahoo refuses to help and claims Thunderbird caused this mapping loop, is there a hidden config setting (about:config) or a database override in Thunderbird that can force the server to release or move this reserved folder back to the root directory? Thank you for your assistance.

Hi.

Just had a not requested update to 153 esr, which in itself is generally fine, with a small exception.

The windows min, max and close buttons all come up with a code.

Probably just some weird setup I have but any ideas will be welcome.

I use userChrome.css to give a background colour, so maybe the ID of each has changes for any css

1. titlebar-min{height:1.66em; background:#00b !important}
2. titlebar-max{height:1.66em; background:#090 !important}
3. titlebar-close{height:1.66em; background:#d00 !important}

but I don't see how that would effect the actual bare icon

Thank you

I am in the midst of the long process of moving most (not all!) of my gmail from the gmail server to TBird, using filters as discussed in this thread.

I've started by first using filters on less important emails (ie so that no true disaster occurs if something goes horribly wrong). As I do so, I have questions!

For example, let's say I use a filter to: copy all the emails from @someone.org to a local folder then delete those emails (from the server)

What happens if one of those emails happens to be within a thread, including emails from people who don't match the filter (ie are not @someone.org). Have I broken the thread forever, ie, has something gone horribly wrong? If so, how do I prevent this behavior/have the entire thread move along with the targeted value? If not, I don't see how I can move email without breaking threads, which is a bit of a problem.

(Also - whoops, I see I should update, but the question remains.)

Thunderbird just updated and the next time I opened it all of the folders I created and the emails I'm storing within them are missing. I found my profile as directed. I'm not sure if I have a backup of it. I've included the screenshot as you ask for. I know that those folders and emails are there as I was playing around with the the 3 lines > View and when I moved between the different choices I saw my folders/emails are all in there.

Any assistance you can provide is appreciated!

I have an email address and I want to migrate those emails to a gmail address. The problem is that I have around 2300 emails. I'm copying about 200 emails to the gmail address. The problem is that is taking too long and it's not copying all of them.

What if I copy all of emails wait to sycronize it and then copy it again? It will work? Or is there another way to do that?

I have tried reinstalling the account automatically and manually no matter which way I do it it just comes up awaiting authorization then just hangs there? I have doubled checked all the settings, imap.mail.yahoo.com 993 OAuth. smtp.mail.yahoo.com OAuth 465 SSL/TLS I have done everything that I can find so am I missing something? Chris

bonjour à vous utilisateur de thunderbird depuis des années, il fonctionne très bien (j'ai la dernière version : Version 153.0.2esr | Publiée le 4 août 2026

- par contre, il me demande les mots de passe à chaque connexion depuis deux jours - j'ai supprimer le fichier key4 mais lorsque je relance rien ne change ; il demande les mots de passe de tous les comptes.

Auriez vous une solution ? merci beaucoup

I have several Yahoo email accounts. I collect all email from them using pop. A few days ago on one of those accounts, when it's polled, the message "downloading 1 of x appears. However, nothing is downloaded and eventually the server timeout message appears.

I tried the repair inbox function, it didn't work. So I deleted the account and tried to add it again. I get the error message "Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) [nsIMsgAccountManager.createIncomingServer]"

However, if I select manual config and test the server it tests ok, then produces the above error after continue.

None of my other accounts are affected.

Any ideas gratefully accepted

I changed my password for Greenby/Plusnet today. Now Thunderbird is unable to connect to them. The password is correct as I can enter website directly. No problems before change. Grateful for help.

Should I reinstall?

Thunderbird has stopped downloading mail from the outlook account for my prime account, but my secondary account also outlook is OK. It kept asking to sign into my account then directed me to a web page to sign in for outlook, but it would only let sign into the 2nd account. I have tried uninstalling Thunderbird and re-installed it but still have the same problem.

Greetings,

I just downloaded Thunderbird onto my new laptop. I use AOL as my mail server (not voluntarily; they own the verizon.net email domain). This is also my 1st foray into IMAP.

On Thunderbird, there are two "Drafts" folders (identical spelling). My draft emails go to one of the two. I cannot unsubscribe from either by using the any of the methods I found on here (including: uncheck, close Subsribe, close the program, wait a few mins, then open the program). The result is that both "Drafts" folder remain on the LH panel and both remain checked in the Subscribe window.

An interesting note is that the properties of the "Drafts" folder that does not receive draft emails is: "imap://w5mt%40verizon.net@imap.aol.com/Draft" with the Name in the Folder Properties window as "Drafts" (this cannot be changed in the Folder Properties window). The properties of the "Drafts" folder that does receive draft emails is: "imap://w5mt%40verizon.net@imap.aol.com/Drafts" with the same Name, "Drafts".

Just to make things more entertaining, AOL Mail also has two "Drafts" folders; one is in the list of folders below Inbox and does not receive draft emails, the other is in the Hidden Folder List and that is where draft emails go. The "Draft" in the main folder list can't be manipulated (e.g. moved). The one in the Hidden Folder List can't be moved to anywhere outside the Hiden Folder List.

In Thunderbird, I would just like the "unused, undesired" "Drafts" folder to either be deleted or hidden. At present, neither option seems possible.

Thoughts appreciated.

Thanks Matt T

I have thunderbird installed on my PC, and my main email account is a gmail account. I download from gmail using POP protocol (SSL/TLS connection security, OAuth2 authentication). I have been using these settings for a long time (15 years?).

This afternoon, thunderbird stopped downloading my messages. No error messages : just "no new messages to download".

I can see (by logging directly into my gmail account using my browser) that there are new messages on the server. They're not spam or junk, and they're not getting downloaded into my (local) spam folder. They're not getting downloaded at all.

I still have room on the google server (it's about 87% full), and room on the hard drive on my computer (about 3 GB).

Seems like soon as a batch of emails download they all open up immediately or at least as soon as I open or delete one they all open. Never had this happening until just late this week.

thunderbird is not able to access mail.twc.com for 2 days now. Spectrum webmail didn't work yesterday, but is now functional. Thunderbird may need a fix to deal with whatever changes Spectrum made to its mail server,
