Thunderbird Community Forum

Yesterday I opened Thunderbird to find that it was trying to download 8205 emails. 15 emails actually downloaded, there were no messages in SPAM folder. The notification at the lower right showed 300 more had 'downloaded' before I shut off the internet, went into Safe Mode, ran a virus check to find no threats found. No SPAM was recorded in Thunderbird when I went back online. There were, however, several files with large attachments so I don't know if this is a glitch regarding data vs. actual number emails because when I checked for updates (see attachment)

I discovered that since Version 115.4.2 I HAVE NEVER BEEN NOTIFIED OF UPDATES OR *FAILURE* TO UPDATE. AUTOMATIC UPDATES have been turned off and will remain turned off due to nearly dialup speed lack of bandwidth. I will abandon Thunderbird for having a fatal programming defect before turning on automatic updates.

My actual email provider did not show 8205 additional emails so I am concerned about a possible malware backdoor. Today 15 emails downloaded while the little notice at lower right said it was trying to download 113 ghost emails. I shut off Thunderbird and came here to post the problem. I will update Thunderbird, but need to know if there is a temporary file cache or some other hideyhole that the ghosts (or some attacker) might be storing godnosewhat so that I can either quarantine or delete them?

Multiple people use this pc and Tunderbird. When I open Tunderbird it show the mails I had last time I openend it. I would like it to be hidden until I enter my password so only I can see the emails. Can anyone please help?

I cannot send emails and always get the same error message, no matter what steps I have taken. This has been the situation for nearly 48 hours. During this time I have undertaken the following steps, as advised by Thunderbird (TB)/ Optus and Google (not in order).

Checked SMTP server settings (many times), Re-booted the Router, Uninstalled and reinstalled TB, Changed the number of Server Connections to Cache from 5, down to 1 (as suggested by the TB Notification), Tried sending a test message to my other email address on several occasions, but got the same error message. I have checked my Webmail account and can send and receive from and to my email accounts from within webmail.

As required in the TB help file, The following information is provided: SMTP settings (attached). Mail Provider is Optusnet. ISP is Firefox. Antivirus is Trend Micro Maximum Security Version 17.9. OS (details attached).

If I have neglected any required info please ask. Any assistance would be greatly appreciated.

Thank you. Flin

I have set up my address book as CardDAV connecting to my Google Contacts. When I update a contact in my Google Contacts online (such as changing the address or phone number), the change doesn't get synced to my Thunderbird contacts unless I go into my TB address book and do a synchronization.

Can my Thunderbird address book be made to automatically sync with Google Contacts every so often?

So I have a self hosted Exchange and I have no problems using it from apps like Google Mail, Outlook and such, plus I can login directly to its .../EWS/Exchange.asmx through a browser. However, when trying with Thunderbird 145/Linux, I always get that username or password are incorrect, but it doesn't tell me exactly what went wrong and how it tried, so I'm in the dark why it is happening. Note: exchange's url is on a different domain than my account.

Basically it's either this message: Authentication error.

Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) [nsIMsgAccountManager.createIncomingServer]

Or similar if I try to get message from inbox.

Also weird things happen during configuration, like attached image (note that I've tried different URL permutations)

TLDR; how do I diagnose the issue, or ever better, how to connect? TIA

I have been using Thunderbird for months on my new computer. Last night when I brought it up, a new screen said "Unable to Connect" followed by good information like check the network connection, firewall, etc., make sure Thunderbird is permitted to access the web. Plus, the PC bubble communicated "Authentication failure when trying to connect to server imap.comcast.net".

I have checked everything (looked around) and all seems fine. However, I am a "senior" and maybe I missed some communication along the way. I am getting emails on my iPhone and on the Xfinity website, but Thunderbird is not connecting to the server now. Do I need to change any settings?

Why are some emails unreadable when the dark theme is enabled, but completely legible when the light theme is enabled? 1st picture is the email with the dark theme enabled, 2nd picture is the same email with the light theme enabled.

I have a web-camera which send a picture to me every 15 minutes. When you start the computer all the new emails are downloaded to Thunderbird. All emails get the same hh:mm and are sorted (I think!) in the order they were downloaded, i.e. the first one is on top and the last one at the bottom of the list.

What I would like is to order them by the subject when time of download is the same. In my emails subject I have date and time which would get them in the correct order.

I would by this get the newest first and the oldest last despite the fact that they are downloaded oldest first och newest last.

Would this be possible for you to do?

Hi. Ubuntu Unity 24.04 Thunderbird 140.5

When creating a New Message, the top 5 lines are missing - i.e the “End: (U)” (end time) line is displayed at the top of the screen. The only way to enter the Title of the Event is to drag the window down. Also, the Event window CANNOT be resized. This has been happening for more than a year now. Can you help? Thanks, M...

This is a new Fedora-42 desktop, upgraded (dnf upgrade) today. I installed Thunderbird today (dnf install thunderbird), after doing the operating system upgrade. I tried to add my yahoo e-mail account. Settings are as follows:

• create accounts in the new Account Hub is unchecked (off).
• accept cookies from sites is checked (on).
• remember password is checked (on).
• I'm using "IMAP".

When I click "Done", a separate window pops up in which yahoo asks for my password. After entering it, yahoo says "Something went wrong", and gives no other indication of what the problem is.

If I instead "Configure manually"... I tried both the default hostnames and "export.imap.mail.yahoo.com" for the outgoing server. I tried both "Normal Password" and "OAuth2" authentication methods.

In all the above cases, I get "Unable to log in at server. Probably wrong configuration , username or password." with a yellow background.

I see nothing of "Edge Too many requests" as was happening to several people recently.

How do I add my yahoo account to this new Thunderbird on Fedora-42?

I'm not able to log into yahoo e-mail via Linux Firefox (145.0 (64-Bit)): The error message is "We were unable to log you in. Please try again from another device." I can log in with Chrome (Linux and Windows) and Firefox (Windows). My issue is to switch from POP3 to IMAP in Thunderbird. There the same error message occurs.

I'm just learning how to use TB. I am looking at my "sent" box, in table view. The messages are, sort of, in date order but it's all a bit jumbled. I've clicked the arrow at the top of the list of messages but all this does is to reverse the jumble! I've tried switching to card view and back but it doesn't solve the issue.

Can anyone help, please?

I have version 145.0 of TB and my OS is Windows 11 version 25H2.

Can the order of the sub folders in email account folders be re ordered. Is the add on "manually sort folders" still available? I there another method of doing this.

I have been using thunderbird since the 90's and have rarely had problems like this. Myself and my provider have spent much time verifying the settings. The messages are thunderbird is rejecting imap and I need to sign in every time I send an email or receive. I never had to do this and never go these messages before beginning about a year ago. After time with question on "ask", no answer resolved the question. I still have to email and the provider states to call thunderbird which has been imposible. This is a first in at attempt of customer service. Thanks for your kindness, my provider says they cannot make the email work and that it is thunderbirds program to contact them. I have contributed in the past and today but it is a dead end. Rich

My Thunderbird has behaved very well for a decade or more. No issues and still the same. My question relates to the delete function. When I press delete I get a warning of a delete email with a chance to go back. I changed this to see what happens and now I cannot find how to return to second chance as this works best for me. Possibly simple but how? regards Replytree

Hello,

I just switched to Thunderbird from Outlook and so far it seems nice but one problem when I click on the get messages cloud icon on the top left of the screen I receive no incoming messages. Now if I go to one particular email account (I have 8 email accounts) and right click and left click on get messages, new messages come in.

So my questions is, why doesn't all my mail come in when I click on the get messages icon? Am i misinterpreting this?

Thank you!
