There must have been an update for Thunderbird that screwed up the way I have been using Thunderbird for years now. I had sub folders under inbox. For example, I had an investment newsletter go into a sub folder under inbox labelled "inv". I had a filter set up to move emails that had the name of the newsletter in the title to go to that "inv" folder. In this new version of Thunderbird, those separate sub folders are gone. The filters are still there but the folders are gone. Now all emails just go into the inbox. Is there a way to roll back to a previous version?

TIA Eric

It started this morning that outgoing emails wouldn't send. Now I'm not getting incoming emails either. I called my ISP and they had me doublecheck my settings and they are all correct. What's going on?

Thunderbird stopped working on my old Mac Mini (2014). I bought another used Mac Mini (2018), running on Sequoia 15.3, and hoped to install Thunderbird on it, but so far I can't. When I try to set it up, it says my account is recognized, but when I click done, I get the message "Unable to log in at server. Probably wrong configuration, username or password." I suspect it's the configuration. I tried my old Mozilla password, when that didn't work, I created a new one, but that didn't work for Thunderbird either.

My email comes from my ISP — AT&T — whose email service is powered by Yahoo. When Thunderbird stopped working on my old computer. I started using MyYahoo email (same email address), but I'd prefer going back to Thunderbird, which is much better for archiving and directing incoming email to folders I create.

Please help.

Dear filter specialists,

On a Windows 10 computer with TB Portable 128.6 and .7, folders can no longer be selected in the filters as ‘Run filter on’ or ‘perform these Actions’: the menu is greyed out. The phenomenon occurs with all accounts: POP and local. Various email providers, ESET virus scanner, Windows firewall, FritzBox cable router. The local account contains almost 30 GB of emails. The existing filters work as long as they do not affect the accounts or folders: for example, tagging e-mails works. Existing filters with folder-actions cannot be re-configured and no folder actions are possible when creating a new filter.

I have performed an update check and restarted Windows, changed the compression limit from 500 to 5 MB and changed a few minor settings so that the config is rewritten.

What could this be? How do I solve the problem? A workaround if necessary.

Thank you very much for your help.

I’ve got a minor but annoying Quick Filter button issue which just cropped up today out of nowhere, and haven’t been able to find an exact match for all these symptoms in any other problem reports.

Toggling my Quick Filter button works as expected, picking up the individual active filter buttons. However, in some instances of launching TB its on/off status indicator always displays as active regardless of individual filter button status. Weirder still, in other cases it always displays as inactive. It’s an intermittent problem, which always persists in one way or the other.

Further details:

- Problem is also present in safe mode, with the single plugin I use (CardBook) disabled.

- General display settings are “Theme Simple” and “Variant Normal” (not “Dark”).

- There are no automatic filters configured in “Tools > Message Filters”.

- Individual filter buttons are all working properly, including correct status indicators.

- Running current TB version (128.7.0esr 64-bit) on Windows 10 with all OS patches up to date.

An example:

Image 1: “Show only unread messages” button is active, and the Quick Filter button also displays as such (both indicators are correct).

Image 2: All individual filter buttons are inactive, yet the Quick Filter button still indicates a filter is active.

I’m stumped, thanks in advance for any help!

Hi,

I've been using Thunderbird for a few days now. I'm slowly learning the ropes. Between my wife and I we use 2 computers and two phones. I have set up the computers to use POP3. My logic being that I want a copy of all email activities on at least one of my computers at home. (I noticed that only my inbox is has been imported to my Thunderbird files on my computers, no other folders have been imported.) However, I've just discovered that when I create and send an email from Thunderbird on my home computer, a copy is not saved on my service provider's sent folder (@bell.net). I'm assuming that is because I'm using POP3. If I understand correctly, if I use IMAP all my folders will be synched (including my sent etc) between my service provider and my computers. Is that correct? If so, then I guess I should be using IMAP instead of POP3. If that's true then is my only option to occasionally archive my Thunderbird files before cleaning up my service provider folders? Thanks for your insights.

Greetings, i have been using thunderbird for years and registered and donated some time back. I recently spoke with my hosting company about updating my billing and while on the line with them the rep said that i wasnt behind a firewall on both my website and email. I said go ahead and do what was necessary. Anyhow, after that point i am unable to receive emails on my main account, butttt, i can compose and send emails 🤷🏻‍♂️. I experienced a similar issue about a year ago and for the life of me, cannot remember exactly what i did to correct it 😳. There was an update somewhere along the lines and resulted in the problem. I did at one time deleted the account and reinstalled and didnt lose anything but cant remember that procedure either. I have all of the correct settings for both incoming and outgoing servers and all sign ons and passwords pass the verification process. Hosting company doesn’t know why it is not working so I thought this would be the next step in troubleshooting. Thanks for any help my thunderbirders can provide. Bob

I have two profiles in my Thunderbird account. I want to create desktop shortcut for each profile. That way I can use the shortcut to get my email. On on profile I just want it to go straight to that account without asking for a password. On the other one I want it to ask me for a password. Is that possible and if so how can I do that?

I have T-bird version 128.7.0esr (64-bit) on both my desktop Dell and my laptop Dell. On the Desktop I have a message filter for removing common sources of spam/junkmail to the Trash. I tried to make that filter available by copying the msgFilterRules.dat file in the Imapmail folder of my desktop's T-bird profile under AppData/Thunderbird (I have a Windows 11 Enterprise OS...the laptop is Windows 10 Enterprise OS) to the Imapmail folder on my laptop's T-bird profile. After this copying process was done (with T-bird not running on the laptop) I loaded T-bird on the laptop, but the filter on the desktop did not appear under filters on the laptop. Note: while the email account for both T-bird installations is the same, the *profile name* is different. Perhaps that is the source of my problem. I *could* backup the T-bird installation on my desktop and then use that backup to install T-bird again on my laptop. But I wonder if there is a simpler solution that preserves the bulk of what is on each of these two T-bird installations?

I bought a new computer and had to download Thunderbird again. I tried the most recent one, didn't like it, so randomly picked a previous release from 2023 (don't remember when I installed the previous one) and hoped for the best. In the past, I would keep some emails in my inbox and tend to them as needed and then keep or delete when I had done what was required. I would also need to go to my ISP email's page, to get spam email, because Thunderbird didn't provide me with those. When there, I would delete what was in the inbox, so I could easily keep letters there to a minimum. Now, however, when I delete something in my ISP's inbox, it deletes in my Thunderbird portal too. I can't find settings in my ISP's page to stop it from downloading automatically (so it won't duplicate what I've already received via Thunderbird), and I can't find any settings in Thunderbird, to ask it to keep what I have in my inbox, instead of deleting everything I delete with my ISP. Do I need to go further back and find an earlier release in order to be able to use Thunderbird as I used to do? Or can I tweak the one I have?

I am having an issue with converting my Yahoo email to Thunderbird. I see I have 6500 emails in my Yahoo email account, but do not see my emails in Thunderbird Inbox.

I have a default view of 10,000 messages but cannot see my first email.

I have used Thunderbird for many years and currently with 4 hotmail and 3 gmail accounts AND...randomly some accounts I have to the enter the Inbox ONLY when i check another link on the account such as "draft" "sent" or other before i am let into INBOX ?? WHY? I have not noticed whether its gmail or hotmail accounts at fault ??

When I create a calendar event, it will not show up in the calendar view (Month), even after trying several times. What I found is, it will only show up on the calendar if I uncheck the Notify Attendees box at the bottom, which is by default always checked. After I uncheck the Notify attendees box on an event, that event, and each successive event will then show up on the calendar, regardless if I have the Notify attendees box checked or unchecked. I looked to see if I can uncheck this box in Settings, but do not see where this can be done.

Is there a way to have the Notify attendees box unchecked by default when I create a new calendar event?

Hi I am having an issue with getting new contacts to add to a email group. It was working just fine and then, I couldn't add anymore new contacts. What is going on and how do I fix it? Sue

Hi,

I'm searching for a possiblity to assign a task to a user, like it is possible for an event. According to RFC 5545 this should be possible for VTODO however in the GUI the "Attendee" field is missing. Is this an intended situation?

Regards

Program keeps crashing on startup. This has been happening for a week or so but it would load second time. Now won't load up at all. I have reinstalled but to no avail

ThunderBird for Linux crashes down automatically every 5 minutes since the last update. Every time I log into my account, about 5 minutes later, I see from the monitoring terminal that ThunderBird's temporary memory usage suddenly soars to over 90%, and then the entire program becomes unresponsive and must be closed and logged in again. But after that, this situation keeps repeating, and it is impossible to use it. Can anyone help? Thanks!
