No longer a Spectrum cable user. Been using Firefox/Tbird for years. Will I still be able to use existing (charter.net/Spectrum) email address via Tbird?

Dear Support Team,

I am experiencing problems logging in to my Onet email account. The issue occurs when I try to access my mailbox, particularly through Mozilla Thunderbird.

Could you please let me know what might be causing this issue? Is there any specific configuration required in my Onet account settings before logging in?

Additionally, do I need to reconfigure any settings in Thunderbird (such as incoming/outgoing server settings, ports, SSL/TLS, or authentication method) to ensure successful login?

I would also like to mention that I do not experience any login issues when using email accounts from Wirtualna Polska (WP/O2) or Gmail in Thunderbird. The problem seems to occur only with my Onet account.

Please let me know if you need any additional details from my side. I would appreciate your guidance on how to resolve this issue as soon as possible.

Kind regards, Konrad

Is the feature supposed to behave this way? I find this rather tedious. Am I missing something here?

Current behavior:

My installation does not seem to automatically execute spam filtering for unified folders or saved searches. As soon as I manually select one of the included folders within - e.g. an individual mail acccount's inbox - the algorithm triggers and everything works as expected, but only for the one folder I clicked. This leaves me with having to click through all my mail accounts manually to make use of the adaptive junk mail controls function.

Expected behavior:

Selecting a unified folder triggers junk mail controls for all the included folders and moves messages to the respective junk folders automatically.

I am a system administrator. My task is to set up corporate email for employees. I tried using the admx template, but I couldn't find the right syntax. With the policies.json is the same, I can't find any documentation that contains examples of these settings. Please guide me.

Cut the cable a couple months ago. Have been using Firefox/Tbird many years. Stopped being able to access old email address of 25 years a couple days ago. When opened Tbird would always got to old email and say "couldn't log in" or something. Would cancel out of that twice, click on new address and collect new address email. Old email was always there, used it as reference during transition. At settings chose new as default and deleted old address. Looks like the boxes checked would not have deleted old email but it's gone. 3500+ of them. No warning, message, choice, nothing. took zero time. Cannot change in Mozilla login to new email address. Tried Tbird import tool, could seem to figure it out. Also need to update email in Mozilla. Help. Tks. x@yahoo.com

I recently lost incoming emails to my inbox. I am in the process of setting up a website and had to change the DNS settings to proceed with the website. Since then I have lost incoming emails to my Firefox email. Which also references the domain name. I'm not technical at all so I'm wondering what I need to try to get back to access. I'm wondering if it's something to do with the outgoing server settings ? Any help much appreciated, thanks.

I have a backup file from another thunderbird installation. The profile in this backup contains a file named abook.mab. I suppose this is the address book. I would like to copy the addresses from this installation to my current thunderbird 147.0.1 (64-bit). Tools > import > address book does not work. Can you please advise me?

every email is being archived and I don't want any incoming out outgoing archive. I have no reason to archive thousands of emails forever. I manage them my self. How can I disable that feature?

Dear Thunderbird Developers,

I am writing to express my frustration regarding the recent UI changes. After the latest update, the standard toolbar icons (Get Messages, Write, Address Book, reply, etc.) completely disappeared for me, leaving behind nothing but a search bar. Even using the "Restore Default Set" option fails to bring the essential navigation buttons back. While I can eventually fix these issues as a power user, these constant, breaking UI changes are a major problem for average users. For instance, my 65-year-old mother relies on a stable interface. Every time a rollout breaks the visual layout or hides basic functions, she is unable to use her email until I step in to fix what the update messed up.

Forcing users to manually rebuild their primary navigation toolbar after an update is not a "feature"—it’s a regression that alienates long-time especially elderly users who need reliability over constant redesigns. Please prioritize UI stability and ensure that "Reset to Default" actually restores a functional set of icons.

If you need further information I'll be glad to hear and hope you can give me an easy fix for this problem.

Windows 11 machine. I have 2 email addresses in my TB set-up, from different domains/servers, one is a Rackspace for my business and the other is Fastmail. I am repeatedly asked for the server password for every single incoming email, and occasionally asked for the SMTP outgoing password when sending. I have put Windows into safe mode and it still happens there. I just don't know what to try next. Thanks in advance, Laurel

For many years I have had a Thunderbird Calendar, and have a large number of Tasks set up in it. I have now decided it would be convenient to link it to my Google calendar, so that it also shows on my new Windows 11 machine and on my laptop. I've gone through the process described in the "Create new calendars" article, to link the calendars, and the Google calendar is now appearing in the Thunderbird calendar, but not vice versa. How do I get the Tasks in the Thunderbird calendar to appear in the Google calendar?

I am running Thunderbird 140.7.1esr and Firefox 147.03 on my Windows 10 machine, which I used to set up the link. My Windows 11 machine has the same Firefox build, but Thunderbird 147.0.1, and the Google calendar display is the same, but I haven't yet set up the Thunderbird calendar on the new machine.

Dear Sir / Madam, I am still running a perfectly good Win 7 computer. My Mail Inbox & Sent Box have a huge number of Emails i have been trying to delete in batches. They initially go to my Deleted folder which shows the number of emails collected. I then empty the deleted folder. so far so good, except the huge file size in my inbox or sent box hasn’t changed! But the deleted folder is now showing empty! The emails i selected to delete seem to have disappeared, but i have not recovered any disk space! I am running out of disk space in C drive because i cannot seem to remove these emails. I have tried shutting down my computer & rebooting (i shut it down every night) this has no effect.

If i had a tool to open the sent / inbox file i could manually delete emails in old date order? Hope someone out there can help.

Kind regards Nick

Hi there,

I currently have three email accounts set up in my Thunderbird client. I’d like to disable the automatic marking of messages as read—but only for one specific account (mainly for my colleagues’ convenience, as it’s a shared inbox).

In Settings > General, I see the option to turn off "Automatically mark messages as read", but this would apply to all my accounts, which isn’t what I want. I’ve checked the Account Settings for the relevant account and couldn’t find a per-account option. I also looked for an add-on that might help, but so far, no luck.

Has anyone found a workaround or solution for this? Any advice would be greatly appreciated !

Thanks in advance, Cheers.
