Thunderbird Community Forum

I am trying to set up a new email address with Thunderbird. I have copied all the imap and smtp settings from my old address in to the new one. It is now asking for a password but I have not been asked to set up a new password for the new address. Where do I go from here?

I am not able to receive or send emails using my wifi, but can using data (same provider). I have queried this with my email host and wifi provider and both have said there is no issue on their end that would block these actions. The email host suggested I change port 465 to 587 for outgoing to see if that made a difference. It did not.

This issue is occurring on the web platform as well as the android app.

The error message in account setting is: an error occurred connecting to gsyd1001.siteground.net:993."

I recently got a notification that a Thunderbird update was available, so the update was downloaded and installed.

Next I went to my inbox to tidy it up, by deleting some items and archiving some that I wanted to keep. On looking at the 2026 archive none of the items where found.

Why has this happened and is there any FIX ?

Hello,

I am struggling to set up calendar and contacts sync between Thunderbird (v155@ubuntu26.04) and my google account. I use a university account to access google services, so my google account is not some.name@gmail.com but some.name@myuniversity.cz. I understand that Thunderbird somehow needs to invoke OAuth2 process with google, but I do not know, what to fill in the "Hostname" or "Location" fields for Contacts and Calendar, respectively. Any help? Thank you.

I wish to have a non American email client, but most free ones have a 1GB limit. Can I set Thunderbird to save all emails to my home PC so that if I delete the email in the email client, it is still saved on my home PC? So far I have not downloaded or installed Thunderbird, so just asking if it is posible, if so I will install Thunderbird.

I am using Thunderbird 140.12.0esr 64 bit under Linux. I was obliged to change my Gmail password. I deleted my Gmail account from Thunderbird. I than proceeded to Add a new account and entered my Gmail account and new password. A blank window popped up: 'https://accounts.google.com/o/oauth2/auth?response_type=code&client_id=406964657835-aq8lmia8j95dhl1a2bvharmfk3t1hgqj.apps.googleusercontent.com&redirect_uri=http%3A%2F%2Flocalhost&scope=https%3A%2F%2Fmail.google.com%2F+https%3A%2F%2Fwww.googleapis.com%2Fauth%2Fcarddav+https%3A%2F%2Fwww.googleapis.com%2Fauth%2Fcalendar&login_hint=gizzenbriggs%40gmail.com' I suspect that this is from Google asking me to confirm my password. Unfortunately the window is blank and I cannot enter anything. Consequently I cannot add a new email account to Thunderbird.

I bought a new computer and want to transfer my emails, calendar and anything else to start using Thunderbird and lightning. I don't want to lose any information. I hope it will be seamless as I use it for business. Both Computers are Dell Laptop with Ubuntu . I am just really old and not too savvy with tech stuff. Will you help me make the necessary transfers? Ever grateful...Thanks, Frances

Prelude:

1. I have several email addresses in Thunderbird.

ISSUE:

1. One address, the first on the list, Draft folder shows "1"
2. View email Shows "No message found"

QUESTION: I like to keep a tidy Thunderbird - how might I fix this issue?

Thanks for the read, ~r BTW - this seems to be the last of the gremlins since my migrating - - Thunderbird - - Yea! :)

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

Most other email clients I've used have had a way to manually "expunge" a mailbox, i.e. delete the messages which are marked for deletion. This includes Thunderbird on a machine at home (I'm traveling right now).

On this laptop I'm using Thunderbird 102.12.0 on macOS 26.6.2. All of my mailboxes use IMAP. Thunderbird is using Maildir for local storage on this laptop, and I believe the same is true on the machine at home (also macOS 26.6.x, not sure of the exact Thunderbird version), but I won't be able to verify this until I get home tomorrow evening.

On both machines, when I delete a message, the message list shows that message with a line through it, corresponding to the IMAP "marked for deletion" flag. The same is true on the other email clients I've used over the years.

On the machine at home , when I right-click on an account's "Inbox" folder, there is a "Compress folder" option which expunges the deleted messages from the mailbox. This option is not present in Thunderbird on this laptop.

So my questions are ...

• Is the menu item I'm talking about, only present when the account uses MBOX for local storage, and maybe I missed a step when I created the account on the machine at home? (If so, I know how to fix that when I get home.)
• Every email client I remember using, all the way back to the original `pine` in the mid-1990's, has had an "expunge" command of some kind. Does Thunderbird really not have a way to manually expunge a mailbox? If so, this seems like a fundamental oversight on the part of the Mozilla developers.
• Or is there a way to do it, and my old eyes just aren't seeing it on the menus? (which is entirely possible)

Thanks.

(Side question, totally unrelated) ... why does the text entry control I'm typing this message into, have its own markup language instead of using standard Markdown? (And yes I am, at least in part, being old and gumbly here ... you kids get off my lawn!)

As above, is there any EASY way to edit the Subject line on a received email. These days, most accounts are via email, and currently if I receive a bill for payment, I have to add an XNote or something similar, to note that I have paid, which means that you then have to open that email, to see it... Would be SO much easier, if I could just add a note to the subject line. Realise that you can (laboriously) go through the actual mail files and edit/create a script to do this, but before I go through the process, was thinking there must be an easier way??

Thanks,

After a long explanation, I tried to add a file and lost everything. Starting over! After using TB for over 30 years, I accumulated a large number of personal folders to archive files to. Due to confusion on my part about pass words in Proton Mail and their Bridge, I had to reinstall my ProtonMail account into Thunderbird. Because all my personal folders were connected with the old "account" name, I didn't remove it, and the new addition seemed to be working fine.

After doing some house cleaning to remove duplicate and obsolete files, I wanted to move the folders attached to the old account name, under the new name. I thought I could carefully move my personal folders from the old account, back under the new Protonmail account. Sadly, that doesn't work like that. What I did find was that the original folders which come under the original "account", were created with an older version of TB, which put them in a folder on my HD. But the new default folders ("inbox", "draft", "sent" etc.) are mirrors of the Protonmail Bridge, which is NOT what I want.

So I need someone that knows how to either place the old folders back under the NEW "account", or how to create new folders that ARE on the HD, and then move the files from one place to the other.

Just to help clarify, here's the location of the old folders as per the "properties" info.

mailbox:///E:/thunderbird data/thunderbird/yetudx3p.default/Mail/Local Folders/Friends & family

You can see the address for this folder is on my Drive E: I can go directly to that address on my drive E and see each of the files.

imap://gshantz%40protonmail.com@127.0.0.1/Folders/2009

This folder is from the NEW account of Protonmail - bridge, and is obviously the web address of Protonmail. It is NOT editable, unlike the above location on my HD E:.

Any help or suggestion would be greatly appreciated, gshantz

I have been using the INBOX that is under my email address. This worked for years except one time before when the same thing happened where the messages are from years ago. I have to go further down to use ALLMAIL to get the current messages. The INBOX shows "3" while the ALLMAIL shows 5,626.

So, the INPUT is not current as before but old messages. How do I fix this?

Thanks,

Eddie
