Thunderbird: форум сообщества

The Inbox on my Thunderbird emails shows 224 messages but do not open. I have tried opening and deleting but to no avail.

IMPORTANTLY I am still receiving new emails.

I successfully linked / synced the thunderbird calendar with the iCloud calendar. Calendar entries manually entered in iCloud or iPhone calendar are successfully synced and are visible in the thunderbird mail. The other way round, syncing the existing entries in the Thunderbird calendar does not work. They do not appear in the iCloud or iPhone calendar. Searching the internet, the specific Thunderbird or Apple help-sites did not provide an obvious solution for this problem. I went through all (or nearly all) recommendations given by Apple, no success to sync from Thunderbird to iCloud.

Any suggestion what to modify or adjust

I have been using Thunderbird for many years. I just got a new computer and installed Thunderbird onto it. I have several email accounts for personal, business and clubs so this makes it easy to keep track of. I have some gmail accounts and 3 different yahoo accounts. Now when I get an email to one yahoo account it prorogates to the other two. This never happened on the old computer do you have any idea how this happened, and more importantly, how do I stop it?

I have changed Thunderbird E-mail account from IMAP to POP3. My question is, How do I get all my E-mail folders from the IMAP into the new POP3 account. Nothing followed the changed accounts formats.

I have an Thunderbird email account both my wife and I use on phones, tablets and PCs. We use imap on phones and tablets, and pop3 on PCs. Occasionally when downloading the email to the PCs the download stops on a specific email and will go no further. All 3 PCs stop at the same email. IMAP can see the email that haven't downloaded, and if I delete with IMAP the email after the successful downloaded email, the pop3 Clients can download the remaining email on the server. This has happened several times and I don't see anything especially weird about the offending email. Usually some small graphics but no large attachment or anything odd? Any ideas as to what is going on?Version 140.12.1esr

Home Mozilla Thunderbird (Not Responding) is all I see on the screen.

I have rebooted, reinstalled and still cannot get Thunderbird to start. I have not touched the C:/Users/.../AppData/Roaming/Thunderbird data (where I assume the problem is).

A while back I complained about this exact thing here: https://support.mozilla.org/en-US/questions/1401708 — thread's archived now so I couldn't reply there.

Ended up building a small add-on myself since nothing else out there worked anymore. It makes every global search open directly as a list, no more clicking "Show results as list" every time.

[https://amaru7.github.io/search-results-as-list|search-result...]

Free, open source, no data collection. Can't be listed on addons.thunderbird.net right now (Mozilla's paused reviewing new add-ons that use Experiment APIs), so it's a manual install for now. Apparently this is getting built into Thunderbird natively from version 154 (bug 580252), so this is really just a bridge until then.

Posting here in case anyone else still lands on the old thread like I did.

It was working fine on the new computer until yesterday. Now I get a pop-up box that says: ' Unable to connect The connection was refused when attempting to contact localhost.

The site could be temporarily unavailable or too busy. Try again in a few moments.

If you are unable to load any pages, check your computer's network connection. If your computer or network is protected by a firewall or proxy, make sure Thunderbird is permitted to access the web.

I set up a new email and must have done something wrong. I'm getting this message: he STAT command did not succeed. Error getting message number and sizes. Mail server pop.gmail.com responded: [AUTH] Username and password not accepted.

What do I do?

I reinstalled Thunderbird and now it tries to access my gmail account even though I didn't add it. I only use gmail when I log into it from a web site. I don't want thunderbird to have access.

On Saturday morning 27 June 2026 I tried to login my Orcon email account via Thunderbird (which I have been using for a long time). But my login didn't work, I got a message saying "login to POP3.orcon.net.nz with username habitation failed." On 30th June 2026 I reported the problem to Orcon.

Orcon gave me the following settings for Thunderbird. I have done that and even made a new account: Incoming Server Type: IMAP Mail Server: imap.orcon.net.nz Port: 143 SSL: Off Authentication: On (username and password required)

Outgoing SMTP Server: Mail Server: smtp.orcon.net.nz Port: 25 SSL: Off Authentication: Off

Since then I have spent many hours and going around in circles with Orcon's Technical Support to resolve this, but no luck. They blame Thunderbird. I used Thunderbird Troubleshoot Mode. The message that comes up reads: login to server mail orcon.net.nz with username habitation failed. Please can you check that your server settings above are correct? And if there is a bug? Irma

Title: POP3 mail delivering into Archives/Inbox instead of real Inbox — folder appears mis-flagged as special Inbox

Thunderbird version: 152.0.1 (Windows 11)

Problem: After migrating my profile to a new computer (copying the profile folder and profiles.ini, both with relative paths), new mail for a POP3 account (server1, account1) is being delivered into a nested folder "Archives/Inbox" instead of the account's real top-level "Inbox".

Evidence gathered so far: - Real Inbox: mailbox://ABC@savba.savba.sk/Inbox — only 1 message, effectively untouched for weeks - Archives/Inbox: mailbox://ABC@savba.savba.sk/Archives/Inbox — 31,186 messages, 10.9 GB, actively receiving new mail (confirmed with a test send) - Both folders display the same "special Inbox" folder icon in the folder pane - Neither folder can be renamed (rename option greyed out on both) — normally only true special folders are rename-locked - Account Settings shows only 3 legitimate accounts (POP3 savba.sk, IMAP Yahoo, Local Folders) — no hidden/orphaned account pointing at Archives - No message filter is causing this (only active filter is an unrelated SpamAssassin rule) - Identity's archive_folder pref is set to .../Archives (not .../Archives/Inbox), so this isn't the manual-archive-target setting either - Checked prefs.js directly: no mail.server.server1.* pref names an explicit "Inbox" folder path, so the special-folder designation doesn't appear to live in prefs.js - Renamed folderCache.json to force a rebuild — did not fix delivery, and also temporarily broke the Send button in compose windows (fixed by restoring the original file) - Ran "Repair Folder" on Archives/Inbox — only rebuilt the message index (.msf); did not change where new mail is delivered

Current hypothesis: The special-folder (Inbox) flag seems to be stored per-folder (likely inside each folder's own .msf index or an internal DB row) rather than in prefs.js or folderCache.json — which would explain why neither cache rebuild nor folder repair touched it. Two folders under the same account appear to carry this flag simultaneously.

Questions: 1. Where exactly is the special-folder (Inbox) designation stored, if not in prefs.js or folderCache.json? 2. Is there a supported way to clear/reassign this flag from a specific folder via the UI or Config Editor? 3. Could deleting just that one folder's .msf file (Thunderbird closed) force it to regenerate without the incorrect flag, without affecting the 31,186 messages in the mbox file itself? Is this safe?

Happy to provide further logs or additional prefs.js excerpts (redacted) if useful.

Thanks in advance.

When I login into Thunderbird, I continue getting the following error message "Login to server imap.comcast.net with username kfn.appraiser@comcast.net failed". I put in correct password and happens again. Mail server is Comcast. Running Windows 11

I am using Thunderbird 152 on a Windows 11 desktop computer. I want to be able to include a hyperlink in the text of an email message. Please advise. Thank you.
