Thunderbird Support Forum

As of Sunday, Thunderbird can no longer reach my ATT server to download email. It has behaved for ten to fifteen years. Last time someone at ATT fixed it. I have been on the phone or on screen with ATT most of my waking hours since Sunday. (In the process I lost my internet, my landline, my cell connection, etc.) Everything is restored except the connection between Thunderbird and ATT. Everyone thinks changing my password will do it. Done it four times. It gets me into the ATT mail. I have replaced the password in Thunderbird settings with it to no avail. Is there anything you can think of? Not only is Thunderbird more attractive than ATT, I have thirty years of mail boxes there, a continuation from Eudora. I will appreciate your wisdom.

I am using Thunderbird 115.12.1 (64 bit) on Windows 10 with the email account set up as POP3 for the Gmail account

I have a subfolder under an Inbox (Gmail account) that is no longer showing up. If I search for an email address from a sender that was in the folder, I get a list of emails showing the dates and subject, but if I click on the email, the tab that opens is blank.

My PC crashed, but I can't say for sure when the folder disappeared, other than I know it was there 4 days ago. It the the only subfolder that is missing.

Any help is appreciated. Thanks

Hi All my emails from before February 2023 have disappeared. I live in Australia my server is Telstra who informed me that it isn’t their fault and that I should contact you. Many thanks Bee

This just started recently, and I have no clue yet how it started or how to fix it. I have tried several "fixes" listed on the internet, but no luck so far. I'm running Thunderbird V 102.5.0 (64 bit) on Windows 11. This does not happen to any other programs that I may be running, only TB and only after I delete the 2nd or 3rd email in my sbcglobal account. It doesn't happen with my gmail account that I have running in TB also. The freeze lasts a couple of minutes, and then reoccurs after I delete 2 or 3 more emails. It seems to only affect my "inbox" and not "sent" or "trash". Sorry if this has been asked and answered before, but I was unable to find it here. Would appreciate any assistance to point me in the direction of a solution. Thanks

I was finally forced to upgrade from win7 (which worked) to win 10 (me no likey) because of a required program which would not even install on win7. After the upgrade, which obliterated my hard drive of several important things, I am reinstalling TB. I always used an NAS directory for Thunderbird, and have email records going back nearly twenty years. I installed TB 115 and have tried several ways to get it to recognize my profile directory on the NAS to no avail. I tried copying data into the default directory the 115 install is looking at. The about:profiles shows it is looking in the correct directory, it produces a parent.lock file in that directory when I run the program. It does not give me my email, or contacts. I do not use the calendar or to-do lists.

My system is an AMD K6-6400K with 16 GB and a 500 GB drive. Though programs are loaded on the drive ALL data is stored in an NAS. There is about 375 GB available on the C drive.

I have used the cmd line to pull up profile manager, added a profile, pointed it to the data that is on the NAS, a parent lock file is created there too but it shows me no mail.

I have edited the profiles.ini file manually to have the program look at the directories, both the NAS and a local directory which has had the old files entered. Neither worked.

I tried opening TB and creating a new profile and pre-loading the info there, nothing. I've been at this for days now. I have uninstalled and removed manually all TB folders and reinstalled older versions to give that a go but without effect. I am no Luddite (Many years ago I owned a system integration, assembly and install company doing networking for the military as a civilian contractor.) but someone has to explain this to me like I am a five year old. There is no reason having my email back should be this difficult!

PLEASE give me a hand?

My TB directory appears in C:\Users\owner\AppData\Roaming\Thunderbird My old data folder was on a network drive at M:\Users\owner\AppData\Roaming\Thunderbird\profiles\k5zbs5az.default When I manually enter the M: address in the profiles.ini file, it "corrects" it to C:\Users\owner\AppData\Roaming\Thunderbird\ even though the switch 'relative' is off.

[Profile1] Name=default IsRelative=1 Path=Profiles/zpfeu8eu.default Default=1

[Profile0] Name=default-beta IsRelative=0 Path=C:\Users\owner\AppData\Roaming\Thunderbird

[General] StartWithLastProfile=0 Version=2

[Install5D388C1349709B37] Default=C:\Users\owner\AppData\Roaming\Thunderbird Locked=1

Running the Mozilla application with a specific profile using command line arguments brings up the program but no mail. It creates a lock file in the correct directory, but no joy.

I get no pop up error messages.

From the article "Microsoft OAuth Authentication and Thunderbird in 2024" there is a screenshot showing a OAuth2 option for the SMTP server setting with STARTTLS connection security. It does not appear for me. There are only the five options, as shown in the screenshot. How do enable the option to be available in the drop-down list or set it?

The available options are:

No Authentication Normal Password Encrypted Password Kerberos / GSSAPI NTLM

I am on Thunderbird version 115.12.1 (64-bit), Windows 11, version 23H2, build 22631.3737

I can not send emails to anyone. I have checked everything listed on the email help support list. I have cox.net and went to them to get answers with no results.

I set up a new Windows 11 PC (64-bit) about 2 months ago, and installed Thunderbird Supernova. I allowed MTS to choose all the settings and everything was working fine until about 3 weeks ago I am now running version 115.11.1 (64-bit). I noticed that many messages I recieve at scheduled times every day were not appearing in my MTS message list until sevveral hours (a few actually took 3 days) after their normal delivery times. Checking with the senders revealed no change to the time they were sent. Looking at the messages when they appeared showed that they WERE received on time. Logging into the web interfaces for Gmail and Comcast/XFINITY email revealed that the messages were arriving on time. The only logical conclusion is that MTS has a problem in its IMAP protocol implementation that does not recognize new/unread messages as such, and therefore does not retrieve them. I am legally blind, and up to this point, mTS is the only fully accessible, easy-to-keyboard-navigate email program.

I have had a client for whom I use an outlook.office365.com "thing" and get/send e-mails through their domain.

In prior Tbird releases it just accepted whatever credentials Tbird presents

Recent release - I still authenticate just fine - can receive and transmit e-mails without issue. But every couple of minutes I get a nag screen asking me to login to login.live.com. I dismiss the nag screen, and can still transmit and receive e-mails. This screen is initiated by a Thunderbird process (I know this because if I kill a Thunderbird process in task manager, the screen goes away and everything works as expected. )

I really want no part of the Windows "Live" thing, and have no idea of what "helpful" changes it wants to make, and so I do not login.

"Settings" are set up with cookies set to yes. OAuth2 seems to be selected.

I see no settings that I could use to suppress the nag ... is there anything I can do???

Thanks in advance.

Device: Desktop computer - Win 7 Pro Email client: Thunderbird Version 102.13 Server: POP settings

I am a Cox email user and was recently migrated to Yahoo. After I input the correct server settings on the Thunderbird app,each time I click on the Get Message button, It starts downloading all (100K+) the email messages in my Yahoo inbox, including the ones that were already downloaded on my computer from the Cox server. Are there certain settings in Thunderbird that will stop this issue and just let me download new messages? TIA -Craig

Im trying to put my email (prkirby@sky.com) on to thunderbird (version 115.12.1 64Bit) running on a windows 11 computer I have 2 other emails which run perfectly All my settings are correct, pop 3 incoming pop.tools.sky.com port 995 outgoing smpt.tools.sky.com port 465 both my username and password are correct, all these settings work when using outlook 2013 pro plus on a computer running windows 7 username and password also work when signing in to emails on different computers When I create the account the message I get is password/usename incorrect Any help will be gratefully received Phil

Hi This morning when I tried to send an email I got a message there was no disk space & so couldn't save copy to sent (I have 848 GB free on HD)

I tried to copy some old sent emails to a folder I've used in the past (old sent) & TB crashed. When I restarted it, many of my subfolders were missing. They are all still showing in Local folders in profile. I deleted all msf files & restarted TB. Nothing.

How can I restore these folders? Hopefully that's possible! Thanks

To the Mozilla Community:

I have a Posteo account and set it up successfully in Thunderbird. Emails and Calendar are both working without any issues.

However, Posteo contacts are not syncing. I used the TbSync / Provider for CalDAV and CardDAV without success. And using the Add CardDAV Address Book in Thunderbird is not working either.

Posteo Support confirmed my settings are correct. (Enter https://posteo.de:8843/addressbooks/johnexample/default in the URL field and replace johnexample with the local part of your email address. )

Any assistance that can be provided to troubleshoot and resolve this issue is appreciated.

Thank you.

A while ago my long-time hotmail account stopped working on two computer with windows 10 and one with windows 11. Last night, I looked up an article that said I have to use Oauth2 instead of normal pw. I made that change on the windows 11 machine and a popup occurred that wanted the number from the google authenticator on my phone. I gave it that and it checks mail now just fine.

This morning I went to one of the Windows 10 machines and did exactly the same. I tried some different server names online and tried some, but after a while I started getting a little window that asked my email address and pw. I put my hotmail address in and got this message:

Microsoft Accounts or personal email addresses don’t work here. Make sure you enter your work or school account (e.g. user@contoso.com). If you want to reset a Microsoft Account password, click here.

Now this is the very same hotmail email that worked on windows 11 with the same server settings last night. It still works.

Now, on the windows 10 machine with those same settings, I get the blank extra window. The extra window appears, does not populate, and disappeared.

It is: https://login.microsoftonline.com/common/oauth2/v2.0/authorize?response_type=code&client_id=9e5f94bc-e8a4-4e73-b8be-63364c29d753&redirect_uri=https%3A%2F%2Flocalhost&scope=https%3A%2F%2Foutlook.office365.com%2FIMAP.AccessAsUser.All+https%3A%2F%2Foutlook.office365.com%2FPOP.AccessAsUser.All+https%3A%2F%2Foutlook.office365.com%2FSMTP.Send+offline_access&login_hint=redacted@hotmail.com

I had no opportunity to do what worked on the windows 11 machine just last night. I cannot check mail on hotmail on this windows 10 pc. I took all the updates available to Thunderbird and firefox. TB is 115.11.1

I'm stopped. Why would it work on one pc and not another? Oauth2 on the windows 11 asked for authenticator. On the windows 10 it never asks.

We've just started having an issue with Thunderbird continually prompting for Calendar passwords, but not remembering them. IMAP and SMTP seem to be retained ok. Additionally, if we just skip past the prompts (we are using around 5 different calendars), and just go and click the "Enable" button....they open just fine and we don't get any prompts, until we close and re-open Thunderbird. We're running 115.12.1 on Windows 10, 11 and Server 2022 Datacenter. It's not a devastating problem, but a little tedious for some of our users that open and close their Thunderbird a lot during the day. We are running "Smartermail" V8909 from Smarter Tools as our mail server. Thanks in advance!

Can't use Gmail account anymore have cleared cookie's and caches removed permissions and account from Google and TB uninstalled then reinstalled then add TB account worked for 2 minutes then got the same error also some emails load while others are just a blank screen all windows 10 and TB updates are current Have attached error we are receiving anything else please just ask Any help appreciated

Hello,

I updated to 115.11.1 (32-bit) and unified folders will not appear and the option will not stay checked. I have exhausted my options. I previously had 64-bit with same issue so I deleted and installed 32-bit as some said this would help the issue ( I'm on 64-bit windows 10 OS).

I've tried deleting smart mailboxes, virtualfolder and jsontreefolder

nothing is working, I am at wits end. Please help!

I'm connecting to an MS Exchange server via smtp.office365.com and mostly this works OK by now. I do have a stupid problem, however: After deleting several folders, they always "come back" as "ghost folders" (grayed out and without messages) and it's impossible for me to get rid of them. Very annoying. I've tried a couple of steps:

• of course, I tried deleting the folders through the Thunderbird interface, also from Trash, where they first move to
• I also tried to delete msf-files associated with the deleted folders -- to no avail
• I also tried to unsubscribe from these folders using the "Subscribe" interface -- this is not possible: I can tick off the folders, save my choices, but as soon as I open "Subscribe" again, these folders are back
• I also tried to use Outlook, but the deleted folders are not shown in Outlook -- it seems to me that Thunderbird has difficulties letting them go

I'd be very thankful for any constructive help!

When I receive junk email, Thunderbird shows mail received (for example 10 emails) there are ...again for example 3 in my inbox and the other 7 are nowhere to be found. Not in junk and not in trash. I am concerned that there might be some emails that are not junk that I am not able to get. I would like to be able to review the junk folder prior to deletion. What setting options do I need to change to make this happen? I am using pop email... Thanks!!

Hello! I have linked my smartphone with the add-on: Provider for Google Calendar. How can I now transfer my existing appointments to the Google Calendar? I tried to export the existing appointments and then to import it into Google Calendar. Unfortunately, this was not possible because not a single appointment from the existing calendar is exported. I just get an empty .ics file. Any help? Please! Martin
