I have been fighting this for a while but I do not receive emails from people with gmail accounts. My email service is from gmx.com that I access from thunderbird. Several months ago I suddenly stopped getting my wife's emails. She now texts me if she needs to send me something. Now the same problem with my daughter's gmail account. I have not received emails from some others that are probably also gmail accounts. I don't seem to have a problem getting emails from accounts other than gmail.

If I go to the gmx site, the emails are there but they are not being downloaded by thunderbird. Thunderbird does download all the other emails, just not the ones from gmail accounts. I have checked my message filters and there are no filters that reference gmail. How can I fix this?

If anyone can help me with this, I'd appreciate it:

Any anyone ever had Thunderbird Email Filter REALLY work? I never have.

- Some emails do get sent to my Junk Folder (where I have it assigned to go to). - Some emails are noted as Junk, but not filtered to the Junk Folder (please see Image). - Some emails are still coming thru as normal emails, with no notification.

I've added an Image of how I set the Email Filter for every SPAM email.

Thank you in advance.

I got an email from Microsoft saying my Live.com or Outlook.com email accounts won't be supported in Thunderbird UNLESS I change the settings to OAuth2 in incoming and outgoing server settings.

I even REMOVED the email account and re-added it making sure it was OAuth2.

But for my live.com & outlook.com email accounts I continually get prompts for passwords from Thunderbird. Sometimes I can't even click the RED X at the upper right to shut the prompt down. I just happens over and over until I give it what it wants.

I am tempted to shut down all Microsoft email accounts and switch to Gmail.

I have Thunderbird version 115.12.2 (64-bit) I used Windows 11 23H2 build 22631.3810 Windows Feature Experience Pack 1000.22700.1020.0

Any idea how to stop these prompts?

I like Thunderbird much more than any other email program I have ever used, and would like to keep it

I downloaded Thunderbird 120 and installed. All I get is error message saying windows is searching for thunderbird.exe and nothing else. Old version has disappeared and I can not uninstall - get same searching for uninstall.exe. I have tried re-downloading it and re-installing it 4 or 5 times, still nothing. help please.

Tried installing v115 latest on Ubuntu. Hangs when I try to set up email acc and it tries to log into the Gmail server. "Danger ahead" displayed on page with no option to force it to proceed.

Thus please dispense with any solutions for this and just inform how I can install v91.1.2 using apt-get

I see you list the versions but I see no where on how to specify which version to install.

Does "mailnews.localizedRe" still work? If yes, how?

The (preinstalled) default value is "AW,Aw,aw". But when I reply to a message whose subject line begins with "AW:", Thunderbird prepends it with "Re:", so that after a few back and forths we have silly subjects like "Re: AW: Re: AW: Re: AW: .............. ".

Has "mailnews.localizedRe" stopped working? Or how can I get it to work? Thank you!

I am running Thunderbird Flatpak from Flathub on Linux Fedora.

I just checked for updates in Software app. I noticed a few, plus system updates so ran them. I remember seeing Thunderbird reported something weird like ‘v128 [arrowright] v115’. I am making that up but I remember two numbers and the left hand one was a higher number than right hand one.

I thought it was odd but carried on, assuming Software updates never go backwards so it must be some weird anomaly. After rebooting, after updates done, I now get an error/warning when I open Thunderbird…

I’m now confused and worried I screwed up my Thunderbird, in which is 20 years of email. Hoping someone can allay my fears and perhaps advise what I should do? thanks

Hello I have a ntlworld.com email as my main email, I recently added a second email address on gmail.com When I try to send an email on ntlworld I am unable, yet I can send emails on gmail. Before I added the gmail.com I had no problems sending emails on ntlworld.com I am able to recieve emails on both ntlworld and gmail.

sorry for the trouble but I am an anologue in a digital world.

I have been using thunderbird without any problems for many years, but recently it stopped downloading emails from my two (IMAP) accounts (different domains, but both using the same host server). And sending emails fails as well with the following message: "Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) send.one.com timed out. Try again."

I can still access my emails through the web but since my entire office procedure is designed around Thunderbird, I'm keen to get this sorted.

One.com - my hosting service - say that there is nothing at their end causing the problem. So I guess its some setting in thunderbird somehow stopping communications with both the incoming server and the outgoing one. I have gone through the obvious steps - checked numerous times the server settings (including changing these to alternatives suggested by One.com tech support) - they are all as they should be. Also I stopped my antivirus for a few minutes, just in case it was that.

All of this happened without any obvious update or change to the Thunderbird version, or any action of mine that could possibly have changed any of the settings.

Any ideas? And if no positive suggestions, does Thunderbird have logs which might give me more information as to why the contact be me and the servers are failing?

How to set message background color besides white? I'm having issue with the white background visually. I'm a Vet and legally blind in my right eye. Solid white backgrounds gives me very bad headaches. So, I would like to change this. Please see the attached image. The white area is what I'm talking about. system: windows 11 23h2 dark theme enabled. thunderbird 128

Hi! Our email server recently migrated from Media Temple to Microsoft and, like many people, we are able to receive messages but not send them. I have gone through the process and updated both the SMTP and IMAP settings to no avail.

One support article says, "Per Microsoft documentation, administrators should visit https://login.microsoftonline.com/{tenant-id}/adminconsent?client_id=9e5f94bc-e8a4-4e73-b8be-63364c29d753 and grant the following permissions in order to authorize Mozilla Thunderbird: IMAP.AccessAsUser.All, POP.AccessAsUser.Al, SMTP.Send and offline_access."

I have followed those instructions and am still unable to send emails from our accounts. The only account able to both send and receive is our admin account. Does anyone know if there are additional settings that we need to configure in Thunderbird or does this need to be done in Microsoft Entra admin center?

I got a new computer (still a Mac like my old one) but evertime I try to import any OpenPGP keys, I just get an error that says “Error! Failed to import key.” and nothing else. I’ve directly exported my onw personla key from my thunderbird on my old laptop, put it on a thumb drive, tranfered it over to this one, and still I can’t open it.

Hi, I am running TB 115.12.1 without any extensions. I have configured caldav accounts, on Forwardemail servers, on TB as well as on Android with DAV5x. Everything syncs without errors and most calendar entries are visible on TB, but not all!!! I have installed OneCalendar app along side TB and OneCalendar shows all calendar entries (as far as I can tell)!

Has anyone experienced similar issues? Any ideas how I can procede would be v welcome. What are the known issues with calendars on TB115.12.1?

Thx everyone.

Cheers, Adrian

Currently using Windows 10, 22H2, Thunderbird 115.12.2. This PC has been working fine since it was built approximately January of this year, 2024. I have not installed any new software or made any major changes for several months. I'm using Bitdefender Total Security. Recently I started noticing this issue with Thunderbird (I've been using as long as it's been out.)

When composing a message, I now see on a regular basis at the lower left of the message window "Assembling message......." or "Assembling message......... Done". Thunderbird does not crash. If I continue to compose and send, the message always sends. So I'm not having the error some others have had in the past. But it does look like the message I'm typing may be having issues being put into the Drafts folder while it's being composed. That seems to be the only operation happening when the message appears.

I have seen this past week the messages sending and being placed into the Sent folder but there have been at least two messages identical to the ones sent that are still in Drafts and are not deleted after being sent. So whatever is going on seems to be a bug with the saving of the draft and then cleaning out Drafts after the message is sent. Note these are text only messages and I did not change any settings in Thunderbird after updating last week.

While Bitdefender updates on a regular basis and Thunderbird notifies me of updates when they are available (same with Firefox), those are the only items being updated so it seems something is going on. I am going to assume this is an issue with Thunderbird for the time being since nothing else has changed. I've gone through tips noted for those having errors sending messages when they get the Assembling message notification but I don't get any errors. Just a weirdness with the Drafts folder.

In the interest of safety, I don't want to turn off AV to test anything. I've also compacted folders to no avail. Seems that notification keeps coming back.

Any additional help would be appreciated.

About 3 weeks ago, I stopped getting email from ATT in Thunderbird. I am able to go online to the ATT mail and see my email, so it is something with Thunderbird. I've looked online for other suggestions and have tried several. Between everything, I've really messed things up and not sure where to start now. Last thing I tried was to delete the certificate and now I can't seem to add a certificate. Not sure if I'm suppose to create a new one or if there is one on my computer.

This morning I found some steps on how to create one. It had me go to the End-to-End Encryption to generate a new one. I didn't see that option, so I created a new OpenPGP key (not sure why I thought that would help).

Maybe the best thing is to try and reinstall Thunderbird.

I'm open to any suggestions.

Thank you.
