Thunderbird Support Forum

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.

On 5th June I received the following message when I opened up my email.

Warning: Potential Security Risk Ahead. Thunderbird detected a potential security threat and did not continue to live.thunderbird.net If you visit this site attackers could try to steal information like your passwords, emails or credit card details.

I have not received any emails since then. Nor able to send any. I can receive and send my emails through my Mail provider- Telstra Bigpond and also receive and send on my Apple iPad and Phone. I have tried turning the computer on and off but this does not help although I am no longer receiving the warning message. Hope you can help fix this. Regards Dawn Howell

I'm a newbie to Thunderbird. I've added an existing email account to Thunderbird, but it displays the emails with the oldest on top. How do I setup the Thunderbird app to display the most recent emails on top?

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!

My aol.com IMAP is used directly only for travel. The same email address serves my Thunderbird POP email. Currently, ALL incoming mail goes to the AOL server. I cannot see the messages nor answer them on the local system. I store nothing on the AOL server. How can I get the incoming mail to the local email tool?

Any work-arounds?

Good morning. I have been unable to receive e-mails since 30/05/2024. Has the fact that I received an e-mail message from "Mail@voice" <mboudreaux@firmgroupagency.com> on 31/05/2024, got to do with the problem. I would be grateful could help solve the problem. Thank you. Emyr Davies.

Hi

I recently changed my email address from johnbugler@phonecoop.coop to johnbugler03@gmail.com.

I receive Thunderbird 'flyers', and I want to ensure that they're sent to johnbugler03@gmail.com. If it hasn't been done already, please change my email address to johnbugler03@gmail.com.

Thanks and regards

John Bugler

Recently the email display has been changed and not by me. At present I cannot receive emails as previously. Also I wish to revert to the previous display of my emails if possible. I can access email via the email.telstra,com site but I wish to stay with Thunderbird. I also do not get emails to my mobile as before

I would like to customize styling for recurring events in Calendar (115.11.1 on MacOS) without using extensions/add-ons. I enabled userChrome.css (`toolkit.legacyUserProfileCustomizations.stylesheets`) and the “has:” selector (`layout.css.has-selector.enabled`). In my userChrome.css, I added styles:

   li:has([alt*="Recurring"]) { background-color:grey !important; padding:1rem !important; }
   li:has(*[alt*="Recurring"]) { background-color:yellow !important; padding:1rem !important; }

Unfortunately, this seems to have no effect upon restarting Thunderbird. However, when I open Developer Toolbox (`Tools > Developer Toolbox > Developer Toolbox > Inspector` tab) suddenly everything works and the stylesheets are applied, but only until Thunderbird is shut down. Weirdly, other custom styles in userChrome.css work ok.

Is this intended behavior or a bug?

I keep getting this message sporadically: "Sending of the message failed. The message could not be sent because connecting to Outgoing server (SMTP) smtp.hughes.net failed. The server may be unavailable or is refusing SMTP connections. Please verify that your Outgoing server (SMTP) settings are correct and try again."

I sent messages yesterday with no problem!

I can't see any issue with the SMTP settings. I've tried troubleshooting mode.

One of my email accounts (the main one) has stopped downloading to my asus Vivobook 15 laptop. My other two accounts are downloading okay and the account that is not downloading to my laptop is downloading to my Samsung mobile phone okay. Please can you help.

I have a SOGo server that holds my address book. The SOGo web interface allows setting of custom properties, something I have used for a long time without problems. I have accessed the address book with Thunderbird both on Windows and Linux (today Windows 11 and Debian 12).

Lately I have problems with synchronization and now I have tried to understand why. I believe that the problem is connected with the transition to vCard Storage in Thunderbird. (See https://developer.thunderbird.net/thunderbird-development/codebase-overview/address-book)

In the Thunderbird error console (on Debian 12 using Thunderbird 115.11.0(64-bit)) I get for a simple VCARD with one custom property (which I created in SOGo):

09:24:18,136 carddav.sync: Error parsing: BEGIN:VCARD UID:56377-6667FA00-1F-59090880.vcf VERSION:3.0 CLASS:PUBLIC PROFILE:VCARD N:With Custom 1;AAAAAAA FN:AAAAAAA CUSTOM1:My custom value END:VCARD CardDAVDirectory.jsm:595:15

09:24:18,136 NS_ERROR_UNEXPECTED: Unable to set Custom1 as a property, use vCardProperties

   setProperty resource:///modules/AddrBookCard.jsm:394
   vCardToAbCard chrome://sogo-connector/content/messenger/startup-overlay.js:551
   fetchAllFromServer resource:///modules/CardDAVDirectory.jsm:590

CardDAVDirectory.jsm:596:19

It does not matter if the SOGo Connector plugin is activated or not.

Best regards Jan

Hello,

I work in a company and we are using Thunderbird for emails. The way me and my coworkers work is that we solving emails we get. BUT. There are two people always here on emails. One of them is taking ODD emails, the second one EVEN. For example I'm the ODD one, so every email that comes in odd time for example 8:31, 8:43, 8:47 etc., are mine and the other person who is EVEN one have emails like 8:30, 8:40, 8:52 etc. So if I make 2 folders one will be called EVEN and the other one ODD is there some way to filter these emails by time?

Thanks for your help and answers

Hi,

I'm trying to automate / batch set the "When getting messages for this account, always check this folder"-setting for a large number of folders so I'm trying to figure how Thunderbird stores the setting(s) of which folders to always check for new mail.

Checking the `global-messages-db.sqlite` it seems like all folders that have the "always check folder"-setting have a `indexingPriority` value of 30 in the `folderLocations` table, but simply setting it to 30 for other folders does not enable the "always check folder"-setting so I guess that is set elsewhere. Where?

Also what other settings are set for the folder when enabling "When getting messages for this account, always check this folder" ?

Thanks in advance /frax

Dear Support,

we want to intergrade Thunderbird to our Microsoft 365 (Exchange Online), but we have massive problems with the authentication of our users.

I have allready configured an the Enterprise Application for Thunderbird in Entra ID and the Clients, excactly as documented in you article: https://support.mozilla.org/en-US/kb/microsoft-oauth-authentication-and-thunderbird-202

We have conditional access policies in out Entra ID, which allow only comliant devices to acess out Exchange Online.

The Thunderbird clients are running on these compliant devices (Windows ans macOS), but it seems that the client is not passing this information through the Oauth authentication (see screenshots 01 to 04 - I uploaded the configuration and all the steps of authentication).

I searched the internet for more then 3 days, but the only thing that I have found about this problem is this: https://bugzilla.mozilla.org/show_bug.cgi?id=1697805

In our Entra ID, we see in the sign-in logs, what excactly is happening with the conditional access (screenshots 05 to 07)

We use the newest client versions of thunderbird.

Can you please help me on this? We realy want to continue to use Thunderbird!

Kind Regards Ioannis Kyriakidis

I have Thunderbird Bets and want emails when opened to be in a separate window as non Beta does. In Settings I've selected "Open messages in - A new message window, but some emails don't wrap text to fit the window but instead have a width & height slider.

Can the Thunderbird Beta software display open emails in a separate smaller window as a default - and more importantly with wrapped text? Geoff

I think that I need to completely uninstall TB Something went wrong on one of my computers, and it couldn't connect to the server. It works on my other computer.

I decided to uninstall TB that had the problem. I did that, but when I reinstalled it, it had all of the same settings and problems. I used RevoUnstaller. because it said When I reinstalled it, all of the stuff and the problem were back.

What is the best way to fix this?
