Thunderbird Support Forum

I have spent the last two days trying to re-establish receiving/sending emails on my Apple MacBook Pro using Thunderbird without success. This problem developed suddenly about 3 or 4 days ago and only affects the MacBook, not any other device (I have an iMac and two iPads). I have gone through the instructions in Thunderbird's support pages and those in Mozilla with no success.

How do I fix this please? Would the easiest way be to simply delete the account xxxxxxx.gmail.com from Thunderbird on my MacBook and re-instate it by adding it back in?

All the setting for IMAP and SMTP are correct and the username/password is identical on all my devices.

I have followed all instructions both thru gmail and Thunderbird. I have tried to use different email/gmail accounts and have triple checked all entries and settings are correct. Am 'normally' reasonably tech savvy but this one had got me. Error message: Unable to log in at server. Probably wrong configuration, username or password.

Please help...at head banging stage :(

Please HELP About a week ago Thunderbird stopped connecting to imap.gmai.com and have authentication failures. I have spent days reading and trying the fixes but still no joy. Please help I'm at my wits end. Reagards

This annoyance started this week. Maybe it is 102? All I know is that messages with several back and forth replies are now ALL opening across the top of the screen. This is EXTREMELY annoying. Please make this stop!

I read about threads. I don't think this is the issue, but it might be. If someone replies to an email from me, I do NOT want to see five messages open across the top.

Thank you for any help in disabling this annoyance.

People I email say, when they reply to my email, they get a non deliverable reply, even though I receive their reply. I have my email linked to my Gmail so I can see my Thunderbird emails on my cell phone. Is there a setting I need to change to get this to stop? Lisa

I'm trying to export my Thunderbird addressbook using the export function. I go to "address book"->"tools"->"export" and I get "Export Export accounts, messages, address books, and settings to a ZIP file. If your current profile is larger than 2GB, we suggest you back it up by yourself." Then it wants to export the whole thing as a Thunderbird Profile with no other choices showing. I can't seem to export the "address book" to the "csv" format which I used to be able to. Any ideas?

Tonight I accidentally mistyped my password upon starting Thunderbird, so I chose "enter new password" and retyped it correctly. But now it won't download my mail, and I can't find any way to try entering the password again. (My password is not saved.) When I click "Get messages" the blue progress bar flickers at the bottom of the screen briefly but the Activity Manager remains blank. No mail is downloaded and there are no progress messages. There is also a small "null" note at bottom left, not sure whether that's related.

I have tried restarting Thunderbird several times, and restarting my computer entirely. No difference. I went into Settings / Privacy and Security and confirmed that there is no password saved. None of the settings have been changed. But I'm not getting an error message when I try to download mail, it's not doing anything at all (aside from the brief flicker of the progress bar).

I tried sending a test message and got the error "Sending of the message failed. The message could not be sent because connecting to Outgoing server (SMTP) smtp.theworld.com failed. The server may be unavailable or is refusing SMTP connections. Please verify that your Outgoing server (SMTP) settings are correct and try again." But none of my settings have changed. I can access my mail via web server so there isn't a problem with the ISP. But answering mail that way is really clumsy and time-consuming. I need my Thunderbird!

I am using Thunderbird 102.12.0 with Windows 10 Pro. I have been a happy Thunderbird user for many years (since 2015 I think) and have never encountered this problem before. I really hope you can tell me how to solve it, I am aware of several time-sensitive messages in my mailbox and I can't download anything. Thanks very much for your time!

I have been using Thunderbird with multiple POP accounts for about 15 years with few problems.

Since upgrading to the latest version, with was about a week ago, emails are downloaded again and again, for as long as they remain on the server, which is for most accounts 7 days.

I can see the emails are marked as read on the server (my host is X-10 Infinity and been using them for 4 years), but every time Thunderbird connects to the server, it downloads all the messages again.

My mailboxes are filling up with duplicate messages, sometimes 10+ copies of each one. I haven't changed any settings on the server or in Thunderbird, so not sure what is causing this.

If I click to Get Messages manually, Thunderbird only downloads 1 or 2 messages, if anything. But for some reason when the scheduled connect runs (for example: every 30 minutes) it seems to pull down all messages in the POP mailbox again and again.

Is there anything I can set or change to fix this please, or is this a bug you are working on?

I really don't want to change so I download messages from the server and delete them immediately rather than in 7 days as this allows me to have a backup in case my computer needs to have a re-install.

Thanks for any help. I'm sure I'm not alone with this problem.

Hi all,

I was looking at emails (local storage, not on an IMAP server) when I accidentally pressed "K". When I did so, the email was still visible, but the left-most column (which for me is the "Thread" column) showed a red-circle with a horizontal white bar on it. At the bottom of the preview pane, there was a message saying:

"Replies to the thread *EMAIL-SUBJECT-HERE* will not be shown".

I've searched and found that the "K" short-cut is: "Newsgroups: Ignore or Unignore Thread" Source: https://support.mozilla.org/en-US/kb/keyboard-shortcuts-thunderbird

...but obviously, I wasn't in a Newgroup... I was in a regular email account!

The result of this is, the email I accidentally pressed K on has now disappeared. It isn't in the Deleted folder (or anywhere else I can find)... it's just gone.

I've done a little testing since. If I press "K" again before switching to a different, then this toggles the red-circle/white-bar in the Thread column, and the email no longer disappears.

But my question is: Can I get back the email I accidentally press "K" on?

Thanks in advance!

Peter.

Changes/updates occurred today to Thunderbird creating problems. Current Thunderbird version is: 115.2.2 (32-bit) However, computer is: 64-bit running Windows 11

Changes observed:

• Icon on desktop changed
• The left pane no longer shows the number of messages in a folder--only the number of unread messages
• When changing a message filter, the window is too big, and I cannot approve any changes--the buttons at the bottom are too far down and are inaccessible. It is not possible to adjust the window size.

The inability to change the message filters is a major problem. I have tried changing:

• Font size
• View
• Density

I have also tried restarting Thunderbird and rebooting. None of these make any difference.

What should I do?

I have Thunderbird set up with four email accounts. Recently, one of them has started saving Sent emails in the Local Sent folder. (Until I found this I thought that they were not being saved at all). Checking the Account Settings shows that the 'Place a copy in' option is correctly set to save in the Sent folder of that account. (see attachment) Can anyone suggest why this has happened and how I can fix the problem? All the other three accounts save in the correct Sent folder.

Installed thunderbird for the first time. Mouse scroll wheel doesn't work in the inbox, in message view, in settings, or in calendar.

The scrollbars are visible, if I click and drag them they work, if I use the up/down arrow keys the window scrolls as expected, it's just the mouse wheel doesn't work. Mouse wheel works in other programs ex firefox.

I disabled smooth scrolling and autoscrolling but the issue persists.

Hi, every now and then, the local folder of my Thunderbird account (C/users/'myuser'/AppData/Roaming/Thunderbird/Profiles) starts growing endlessly. At some point there is no space left in my PC and I have to remove thunderbird and re-configure it from the start. For instance, now it's 43.3 GB large (it can go up to > 150 GB), but the inbox and outbox folders are ca. 14 GB (checked from 'Folder properties' inside Thunderbird). It is apparent that there is something wrong and I am tired of this situation. Could you help me ? Thank you Lorenzo

I have received notices from Google for all of my Gmail accounts that I have on Thunderbird that beginning in May 2022, an id and password will no longer be supported for "certain" apps. I am not sure if this includes Thunderbird - both for email and for calendar? Does it include Thunderbird and what must be done on Thunderbird to continue receiving email and calendar updates?

This is an intermittent problem. Sometimes Thunderbird refuses to send charter.net email. I get this error msg:

Login to server smtp.charter.net with username xxx failed. (xxx is my email address)

Resetting the modem and rebooting the computer don't help. This happens on multiple computers. Changing my Spectrum password doesn't help either. Spectrum support said I need to switch to Gmail or Outlook, which would be a major nuisance.

In a day or two it probably will start working again. Also, it basically never works when I'm traveling. Sending email from the Spectrum website works fine, and I can send from my Android phone no problem. I have Gmail on my android tablet and it can't even search for emails so I have zero confidence in that, plus I have many folders of emails going back 10+ years on Thunderbird which I can't port over to another email program.

I saw the previous conversation blaming the problem on Thunderbird, which isn't helpful.

Good Afternoon

I am trying to add a signature to my outgoing emails. This is the first time I have tried this. I have followed the instructions but my signature is not displaying exactly as I have typed it.

My signature has my name, address, telephone number and email address typed vertically and covering 6 lines with spaces between the lines.

When I go to compose a new email all the details of my signature are there but are being displayed all in one single horizontal line.

How do I get my signature to display vertically covering several lines?

I just installed Mac OS Ventura and now get “Thunderbird.app” is damaged and can’t be opened. You should move it to the Bin when trying to open Thunderbird.

Any isea on how to fix this?

I had problems with thunderbird email text too small. Resolved that but now the title line with subject to and from is too large. How do I change it. Windows 11 latest version of thunderbird.

Hi, I run mail server on Ubuntu 20.04. Since last official Firebird update I can't fetch the emails from it. Fetching from gmail accounts works ok. Also getting emails from this server using other email software works ok. The error I'm getting is: services.settings: Failed to load last_modified.json: TypeError: NetworkError when attempting to fetch resource

Any advice? Thanks, Michal
