Hi there - been using Thunderbird for donkeys (since it was Eudora!). A few weeks back I started to get messages from Microsoft that I needed to change security settings as they were no longer supported on 3rd party email handlers like Thunderbird. So I re-created the three accounts I had there and it seemed to be OK, though SMTP did not have the OAUTH2 option available ... and when I tried to use the new SMTPs they wouldn't work. So I reverted to the old settings there and it worked again.

But this morning, with the big update to Thunderbird Nebula, I can no longer send emails from the MS accounts. My Gmail one is still OK ... but whatever I try, I cannot get the MS ones to send emails - I get a failure connecting.

Login to server smtp-mail.outlook.com with username xxxxx@hotmail.com failed.

I checked on MS and the details shown there:

SMTP server name smtp-mail.outlook.com SMTP port 587 SMTP encryption STARTTLS Authentication Method OAuth2/Modern Auth

Are what I have (I did have a different SMTP Server name came up - smtp.office365.com - but that doesn't work either)

So ... where is the issue? Is this a bug in the new Thunderbird setup? Something else? I don't know where to go ...

A few weeks ago after an automatic update I ended up having Thunderbird version 131.0.1 installed, I have no idea how this happened. On opening I get a message telling me I shouldn't be using a beta version and that I should revert to the latest general release version (128.4)

Today when I had some free time I downloaded 128.4 and installed it. On opening it it says that I can't use a profile file from a later version with the earlier version. Is there a way to recover from this WITHOUT having to set up the whole profile again from scratch.

Meanwhile I have done a system restore so I am back with 131.0.1 It has not given me any problems so far. Is there a new general release version imminent that will get me back on track?

I would appreciate any help I am not a computer expert, just a user, and find Thunderbird a very good email client.

The Reply command no longer shows when I want to send an email back to the person that sent it. There is a note at the bottom of the email that says: A unique identity matching the From address was not found. The message will be sent using the current From field and setting from identity Vince Hunter < omni232@telus.net> Can you give me instructions in laymans terms to fix this bug and return it back to the way it was?

As you can see in the screenshot, the umlauts are missing in many emails. Unfortunately, the corresponding fonts can no longer be set in Thunderbird; I use version 140.6.0esr (32-bit). Where can I set that ä, ö, ü, ß (...) are displayed normally? Greetings from Berlin, Markus

Hi I was using TB 142 without problems. When upgrading to 143 ou 144.B4 I have problems sending mails to all users after some times. Usually the first mails are sent immediatly but after around 10 mails, I have very slow response (varies from 5 sec to more than 1 minute and sometimes timeout). Usually quitting TB solves the problem but this is very annoying. I went back to 140LTS and sems to have no longer this problem. This was tested on many diffrent networks. I am running under Fedora release 42

Thanks

Hi. I donate 20 bucks a month to Thunderbird. Love it.

Was wondering if there is a way to disable the "support thunderbird" pop ups that always occur upon launch.

Much obliged.

About a month ago I began the process of upgrading from W10 to W11. In the process, several problems happened. One of the problems was with Firefox. After reading and trying many suggestions from the Mozilla site, as well as several other sites, and having no success, I posted my problem on this Mozilla support site and hope that there was someone who could help. There was. After several days of exchanging messages (suggestions, instructions and results - mostly about Profile), Firefox returned.

The other major problem is Thunderbird. I have downloaded a current version (128.5.2esr). I have run it twice and, each time, email was downloaded. So that part seems to be working. What doesn’t appear are the settings I have used and message folders I have created over several years. I suspect that the problems are Profile related.

Starting from Help in the Thunderbird menu, then Troubleshooting Information, then Application Basics, I see Profile Folder. On that line is a button labeled Open Folder followed by (Local Drive). I click Open Folder and File Explorer opens to a folder named ab3xaztm.default-esr. It shows that the folder contains 59 items, including 10 subfolders. All files and folders show a December date.

Following the path C:\Users\rsuth\AppData\Roaming\Thunderbird\Profiles\, in addition to ab3x…, there is another folder nlys3gkl.default that contains only 1 file, times.json.

Because of my earlier struggle – and eventual win – with the Firefox problem, I think that the Thunderbird problem might also be fixed in a similar way: Profile.

Slightly before the upgrading from W10 to W11, I made a copy of my Thunderbird folder. I think if I replace the currently active Thunderbird folder with the one I have saved, my Thunderbird problem may be over. However, I’m not certain that will happen and I’m not certain about the specific steps to take to make the replacement. (With my Firefox issue, there were a couple of small important steps I had to take to make it work, and those steps were explained to me by the person who helped me with my Firefox problem. So, after all these words, can someone point me in the direction to solve my Thunderbird problem?

Thanks for reading.

I use an AOL email account and Thunderbird on my Mac. In Thunderbird, the junk mail folder - which AOL call "Bulk Mail" for some reason - has moved to the Trash folder and I can't get it out. It's a Thunderbird problem - if I go onto my account at AOL.com, everything is normal. How do I get it out? I've tried cutting and pasting it, creating a new folder...nothing seems to work. I don't want to empty the trash in case I no longer have a junk folder at all

Mon compte thunderbird a été supprimé En réinstallant Thunderbird, j'ai récupéré la réception des mails récents et le carnet d'adresses mais perdu les messages envoyés, en instance , les brouilons, les archives. Je les vois toujours dans C/Utilisateurs/nom/Appadata/roaming/Thunderbird/Mail/pop.sfr.fr et ensuite dans archives.sbd et inbox.sbd . Comment les importer dans thunderbird. J'ai essayé l'importation du profil sans succès. Merci de votre aide

I am trying to upgrade from 128 esr version to the new 139 version. I tried several ways to transfer data from the old version to the new version - I tried to export and import a the Thunderbird zip file. I also tried to open profile manager and creating a new profile that refers to a copy from my old version. Nothing has worked. In the old Thunderbird 128 version, if I select Help and Troubleshooting Information and then Open Folder next to the Profile Folder I get an error in Thunderbird that it can’t find my profile. I get the same error message when I go to Tools, export and select "open profile folder." This in spite of the fact that the old version continues to correctly display my contacts, tasks and events

After several hours of this, I finally decided to download version 139 using the standard Mozilla set up even though my Thunderbird 128 version is located someplace else. So, at this time I have two working versions of thunderbird on my computer – the old 128 version with all my data and the new 139 version with no data.

I think I need help figuring out which Profile has my contact, calendar and task data. Then I need help getting it to the new version.

Thanks

I use SMTP settings

Description: smtp.office365.com Server Name: smtp.office365.com Port: 587 User Name: mypersonalaccout@hotmail.com Authentication method: OAuth2 Connection Security: STARTTLS

but TB is incapable of sending email. Either I got dialog https://software9119.technology/__other/tb/dialog.png or error https://software9119.technology/__other/tb/timed-out.png.

I tried cleaning cache and made some re+/search with no avail. There seems to exist some Authenticated SMTP but this is only available on Exchange 365 while this is my personal Outlook.com account.

Same question had Bill Swartout at 1/9/24, 2:30 PM with no answer, https://support.mozilla.org/en-US/questions/1423404#answer-1629472.

I've always experience occasional TB crashes. According to my log history there was 1 in July, 3 in Aug, 2 in Sep, 2 in Oct, and 6 in Nov. I never really paid attention since the reboot was quick. But now in December I am losing work and it is a major problem. I've had 30 crashes in Dec and 21 in the past week. I have only 3 add ons and they have not changed, and a Copernic connector. I disable the Copernic connector and it didn't help. I have the same 140.6 on my Surface Go with the same add ons, except for Copernic and it runs fine. On both PCs I use Malewarebytes and WinDef. I have put exclusions for them in their setups. Even with MBAM completely disabled I've still had crashes.

I cleared the Cache and no help. I've even had occasional crashes in Troubleshooting mode. Here are my last 5 crash IDs

bp-070bf941-4e8b-41a3-8b84-3e3440251224 bp-a936f7c2-9ee3-4c38-b304-dab830251224 bp-8be9cf9e-8f2f-49bb-95cf-47e780251224 bp-12f8fc2c-c505-40f0-8c67-44b730251224 bp-9013fb78-086c-4327-9de8-62db30251223

Interestingly I’m also experiencing crashes with Firefox, especially ChatGPT. I cleared the ChatGPT history and that helped but did not solve the problem. I cleared the Firefox cache and in troubleshoot mode still have issues.

Otherwise my win11 PC seems to be working fine. I’ve run chkdsk and all is ok. Also scannow is ok.

Is my next step a profile rebuild?

One minute I'm able to send emails. The next -- not. Spectrum SMTP server: mail.twc.com port 25 SSL/TLS normal PW "Sender rejected AUP#Out-1500"

Spectrum support is completely useless as usual.

I changed my gmail account password, and Mozilla Thunderbird is losing its mind. I did the Oauth, logged in, but Thunderbird keeps popping up "Mozilla Thunderbird Email wants to access your Google Account" over and over again, even though I keep clicking on "Allow"!

I had an TB account with Spectrum but lost it when I didn't have Spectrum anymore. I got Sprectrum as my internet provider and am trying to create a new TB email account but have not been successful. Can you help me
