Thunderbird Support Forum

I have one message filter (for the Spam folder) with 50 rules to delete known repeat offenders from the Spam folder. The filter doesn't seem to work at all, even if I try to run the filter manually. Why won't this filter work?

I'm only seeing the first email in a conversation if I look in the email inbox. I can see the conversation in the search results if I search for a string contained within the email. But if I just look at my emails in the inbox it looks like I never replied to the email and that she never replied to my reply.

The use of a separate filter set for each Thunderbird account can be a major pain for some users. I have 32 email accounts (some of them disposable) in a number of domains for a large number of purposes. Sometimes several accounts need the same filter, so when I add a filter I add it to the dominant account, and then have to copy that filter set to the other 31 accounts. I suggest adding an option that would use the same filter set (the one for the dominant account makes the most sense) to be used for every account, eliminating the need to copy filters.

When I tried to open my email this morning everything was gone!! No folders, no inbox, no contacts NOTHING. Then it started down loading messages from six years ago. What is going on? As of right now I HAVE LOST EVERYTHING! HELP!!!!!

Every time I use TB now it asks me to compact (delete) my trash. I want to keep my trash. I don't want to move it but I do want to keep it. How can I turn off this super-annoying continual pop-up?

I am trying to create a subfolder in one of my existing email subfolders; whatever name I try to give it, it doesn't work. If I name the subfolder "test" it works. If I try to then rename the subfolder to the name I want to give it ("accelerator program"), it gives an error message that it cannot be renamed ... I find this all very weird. I have many folders and sub folders already to organize my mails, and this has worked for many years and now it suddenly doesn't work to make a new one ... any suggestions ? Is there a limit on the total number of (sub) folders one can create in Thunderbird ? Many thanks for your suggestions or advice.

Hi there! I recently added 2FA on my Google account using security keys and I had to re-add my Gmail account on Thunderbird after invalidating all existing sessions. Adding my Gmail account works well up to a certain point; I can authenticate in the Google pop-up window and use the security key fine, but then when I click the "allow" button of the permissions step, it seems to accept the mouse-click as buttons turn grey, then it doesn't go any further. I've tried this several times over the past few months and the issue still persists. I am using version 91.7.0 (64-bit) on macOS 12.3.

As of a couple of days ago, Thunderbird will no longer allow me to send emails to more than one recipient. The email just stalls out on "sending" if there is more than one name/address. Doesn't matter if the additional names are in "to," "cc," or "bcc" fields. I've tried finding other reports of this online but no luck. I've rebooted Thunderbird several times. Version is 97.1.0. Please help - thank you!

I'm new to thunderbird and, when I first added my aol mail account as IMAP, I deleted (thru thunderbird) what I thought were random, extra folders that appeared under all the other standard thunderbird folders - these were not folders I created, but rather ones I assume aol added for every account. All were removed from the aol mail site save an "Archive" folder which does not allow me to delete it even though it is under the folders section.

I didn't think anything of it at the time, but now, a "Draft" and an "Archive" folder are spawning in the trash section for my aol mail account on thunderbird and I cannot for the life of me get it to stop/move them/etc. These are not the standard "Drafts" and "Archives" folders of thunderbird fyi, but aol's Drafts section (the one on the server has an s even though the folder in thunderbird does not) and Archive folder (which I mentioned above). If I save anything to the standard thunderbird folders, a "Drafts" and "Archives" folder appear in the folder section in aol mail.

I have my settings set to use the standard thunderbird folders, but the ones from aol keep spawning in the trash every restart no matter what I try. I know it's just copying things over or whatever and I don't mind the folders appearing, but how the hell do I get them out of the trash?? I've gone so far as to completely uninstall (including the appdata folder) and reinstall thunderbird, but that didn't change anything. Are there some other settings or something somewhere that I missed? They're not appearing in the trash on the aol mail site, so I'm assuming this is something wrong on thunderbird's end and is messed up because I deleting those original folders. Is there any way to fix this?

I get this message: Secure connection failed

         start.thunderbird.net uses an invalid security certificate.

The certificate is not trusted because the issuer certificate has expired.

(Error code: sec_error_expired_issuer_certificate)

How do I fix it? Thanks, Susie

I searched the help and F&A section and tried to google for an answer – but found nothing. So hopefully someone here can answer my (may be too obvious) question.

With an IMAP account set up – WHERE will folders be compressed if the command is executed In the SERVER, on my LOCAL hard drive or BOTH?

I do not want to (actually must not) change anything on the server – I only want to compress my local hard disk.

Version 78.2.2 (64 bit) automatically installed today. Other than the changed interface (which I can do without), it now asks me when I delete an email message: "The messages you have deleted can be purged from disk. This operation will save about 1.1 GB of disk space. Select the option below to let Thunderbird do this automatically without asking you."

I do not want to purge my deleted messages. If I want to purge an email, I hold down the shift and delete keys and the email message is not saved to my Trash folder. However, I save my old Trash messages in a separate archive. I do not want to be constantly asked whether I want to purge these messages because I do not want to do so. This is becoming a nuisance

How do I stop this?

Thanks for your help.

recently and without other changes that I am aware of my thunderbird pull down menus do not populate with text, or sporadically do so after delay of 15 - 30 seconds.

After update to Thunderbird 91.7.0, I cannot send emails, receive error

The message could not be sent using Outgoing server (SMTP) smtp.windstream.net for an unknown reason.

And, I had other Outgoing server setups and they are now gone.

Is there a bug intoduced with this update?

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 am using Thunderbird 91.4.0 on Windows 10. Since this upgrade any email in my inbox when opened has the "A unique identity matching the From address not found" message across the bottom, red 'table indicator' boxes in various places around the message. The links in the email do not link, they bring up a box with various information including the link address. Reply-to shows the sender's address and To field shows my address. Reply, forward, delete buttons are missing. If I move the arriving email to another folder it looks normal, but if I hit 'reply' it gets all weird as above again. I saw that this was a bug a couple of years ago with a version about 20 versions back. What's going on? And more to the point, how can I fix it?

Thank you for any help that you can offer.

Google has announced that after May 30, 2022 third-party apps that log into google with account name and password (which I assume includes Thunderbird) will no longer be able to do so, as they will enable 2-step verification. I currently and for years have used Thunderbird to pick up my mail from 5 accounts, 3 of which are gmail accounts. Will I be able to continue using Thunderbird after May 30, 2022? I have been unsuccessful getting any helpful information from google itself. They don't have a list of "trusted" third party apps that will continue to work with them. Anything people know about this will be helpful to me and appreciated. Thanks.
