Somehow my account folder has duplicated itself, complete with Inbox, Drafts, Sent and Trash. Going to Settings, I can't see any difference. Both continue to be updated with new mail. How can I delete the duplicate? I see nothing in 'Account Settings' that would let me delete it.

“My Spectrum email address is crewbot@charter.net. Spectrum webmail can send and Thunderbird can't receive or send. The outgoing server is mobile.charter.net and the connection times out. I tested the connection from my computer and ports 587 and 465 both respond successfully. Thunderbird is set to No Proxy. when i tried to send today, it gave me this message, "Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) mobile.charter.net timed out. Try again." i contacted spectrum about this and now when i try to send, it says nothing and the message never arrives.

Hello Thunderbird Support, I am experiencing a severe IMAP folder synchronization loop with my Yahoo Mail account ([redacted]@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.

Dell Desktop - Windows 10 to Lenovo Laptop Windows 11 I followed the Alternative Manual Transfer between Windows 10/11 Roaming Profile and Local Profile Now on Lenova - Mozilla will not open - Profile Missing - Your Thunderbird profile cannot be loaded. It may be missing or inaccessible. I do not know how to uninstall it or how to start over.

T-Bird's pop-up window requesting password keeps popping-up on my screen every 15 to 30 minutes or so ALL DAY, regardless of whether or not I fill-in the password or cancel the po-up. No idea how to make the sun-on-da-beach stop! PLEASE, anyone that has experience w/this... HELP!!!

I've encountered a stange issue: By default, a quoted reply is indented to the right with a vertical line on the left side. Since some time, this vertical line disappears when composing a reply - i.e., when clicking "reply", the compose window opens where the vertical reply bar shows up on the left for a split second but then disappears, leaving just the quoted text without indentation or reply bar. Compose in HTML is on, but it shouldn't matter for the reply bar display anyway. Reply quoting is also enabled, of course.

I know the reply bar can be toggled in the config by mail.quoted_graphical and mail.quoteasblock, but both values are already set to true. Setting them to false should completely disable the reply bar, but it shows up for a split second and is "auto-removed" in the compose editor. It's also not just a display issue in the editor because a recipient doesn't see the reply bar either.

Is there anything else I can check? Most likely it can be resolved with a clean profile, but I want to save the pain of setting up everything again if possible. The issue occured over the span of multiple recent TB versions on Windows 10.

Hallo,

ich benutze Thunderbird 154.0 unter Windows 11 Pro, aktuelle Updates. Seit geraumer Zeit bekam ich die Meldung, dass Ordner Posteingang nicht komprimiert werden kann, weil er ungültige Daten enthält. Das habe ich heute abgeklemmt, indem ich die automatische Komprimierung abgeschaltet habe. Danach war eigentlich alles gut und ich hätte besser nichts mehr machen sollen. Aber dann entdeckte ich den Button "Ordner reparieren". Nachdem ich den geklickt habe, werden mir im Posteingang keine Mails mehr angezeigt, Anzahl = 0, Größe auf Datenträger jedoch 2,3 GB. Die Daten scheinen noch vorhanden zu sein, nur die Anzeige scheitert. Im Papierkorb sind die vermissten Mails auch nicht zu finden. Alle anderen Ordner sind inhaltlich ok. Ich habe eine 5 Tage alte Sicherung, die ich auf einem anderen Windows-11-Rechner mit frischer Thunderbird-Installation eingespielt habe. Leider zeigt sich dort nun das identische Problem. Hat jemand eine Idee?

Viele Grüße Peter

This is simple. Getting here is not. The issue is the zoom feature which many years ago I could not find. Now it is available and that is great, except: The CTRL + and CTRL - do not work until you first use the function in the menu. Once I use it in the menu I can use the key stroke several times to get it where I can read it. Every time though I have to go to the View function in the menu first. Simple fix.

Hello, T-bird gurus! Hoping someone, or a collective of someones, can help me out, as I just started using T-bird again after an intermission of over a decade, and I'm experiencing several progress-stifling and highly frustrating issues that unless easily overcome, will soon have me doubting my choice and abandoning the attempt (although I'd love not to have to). Whenever a new message is received, T-bird's pop-up notification lets me know that it has arrived, and the new message counter in the taskbar also displays an updated count, yet, more times than not, the inbox simply refuses to display the new message/s. When this happens, even if I switch out of the inbox into another folder and then back to the inbox, the new message/s are displayed (but the counter in the taskbar icon DOES reduce the count, as if read). If I was lucky enough to be looking at my monitor at the same time that the notification popped-up, and I was able to read who it's from before it vanished, and then performed a search for that specific sender, the search itself displays the new message, and I am even able to reply to or forward it from there, but STILL... no new message in the inbox once I return to it! Seems the ONLY way to get it to display in the inbox as it should is to close T-bird and re-open it... Then, there it is, sitting in the inbox, taunting me like a child that knows he's got your number when it comes to playing hide-and-seek (lil' booger!). Between this and my other T-bird issue (which I will put in a separate help request), it's got me ready to just pull the plug on TB and add my account to my company's Outlook... which I'd HATE to have to do, especially because it's setup through an enterprise account along with the rest of Microsoft's now full-subscription suite of programs that command a lifetime of automatic monthly payments in order to use them, so if I ever cut ties with that company, I might run the risk of losing access to my other email accounts. Not to mention the uneasiness that loading my passwords into that type of shared system has me feeling, in general. HELP!!!

Can't sign in or change password. can't get mail or send. I have email through Yahoo. (Comcast.com) The below message pops up all the time.

My computer had corrupt files on it, so my computer guy had to reinstall windows 11 & all my other folders to my computer. I re-installed Thunderbird with the new version 154.0 & all of my old emails are there but NO email addresses or contact addresses I had saved in there. Please help! Can I download an older version of Thunderbird 139.0.2 from June 17, 2025 for all of my email addresses to be there & contact addresses?

In a prior version of Thunderbird all the folders with new e-mails were grouped together in a separate pane that appeared at the top of the folders list. In the latest version of thunderbird, this feature appears to have disappeared. Is there a way to restore this feature?

Hello. I regularly sign up for online conferences, then when I get the confirmation email with the details I can't transfer it to the calendar. I even tried saving the ical event separately but when I try opening it using Thunderbird I get an error message. The only way I found is to transfer the contents manually and create an event on calendar, which is time consuming. Anyone knows how to fix this? Thank you in advance

I changed my password in my Juno account and have logged in via a browser with the new password several time. But Thunderbird attempts to connect continue to fail. I deleted the old password in Thunderbird in the Privacy & Security section thinking it would update when the new password works - unfortunately, it never works. I reviewed all the Juno settings in Thunderbird and they are all consistent with the Juno Support recommendations. Now what?

First, thank you for your work with Thunderbird. I am on Thunderbird portable esr update channel. I connect to work email outlook. How do I manage a transition given that Microsoft will stop ews on October 1? Is there a new version of Thurderbird that will be released through the esr update channel to allow connectivity to Outlook? With thanks.

This is the message I get when it does not go. I contacted Spectrum and they told me to check Thunderbird.

Sending of the message failed. An error occurred while sending mail: Outgoing server (SMTP) error. The server responded: p-impout004.msg.pkvw.co.charter.net cmsmtp 73.238.167.193 blocked.
