Following installation of the 32 bit version of Thunderbird 128.0b on 12 June 2024 the content of all emails in the Inbox which existed at that date - and back to 28th September 2021 - would not display at all.

Emails in the Drafts and Sent areas were unaffected.

Emails received since 12th June are displaying normally - as are e-mails dated prior to 28th September 2021.

I have re-indexed the Inbox with no improvement.

The INBOX e-mails show quite normally in Windows Mail -which I only use on my laptop.

The newest incoming email is hidden behind the tool bar at the top of the main mail window. I have to scroll UP to see it. My apologies in advance. I am not tech-savvy. Thank you, A Really Old Fa*t

cannot log in to 'Host'. at bottom of page it reads : "email adress: Host contacted, sending login information..." thunderbird connects through a bt account and i think some difference has arisen preventing one connecting with the other. there has also been a notice saying the 'bt account settings are out of date' which may be preventing Thunderbird loging in. since the notice gives no further information i have no idea what means or what to do about it. have tried uninstalling and reinstaling Thunderbird but that made no difference. hope you can help, i have no idea what to do and am emailess - which is a terrible thing to be!! thank you steve

Hello, ive been using T'Bird as my business email client.

Whenever I hit send it requires me to type the password in. How can i get it to remember it? Ive been through the settings and there is no option to save.

Ive tried deleting my account and adding a new one but its no different.

Currently my emails are sorted by conversation. I want this stopped and all messages simply sorted only by date and time. The reason is that some conversations now have 30 odd messages and I have a terrible time finding the exact message I want. This would be much easier if all emails were sorted by date and time only as I can see the title of each. How do I stop sorting by conversation and replace it with standard date and time?

I am using Thunderbird 115 with mostly default settings. When I compose a brand new message, pressing the Enter key inserts a new paragraph, with extra line spacing, and pressing Shift+Enter inserts a line break with single line spacing. This is how I want things.

I am experiencing a problem when replying to emails from a particular sender. Their emails HTML code contains a "<style>" element that removes the extra spacing for paragraphs:

<style type="text/css" style="display:none;">P {margin-top:0;margin-bottom:0;}</style>

When replying to their emails, their HTML is inserted as quoted text, and the "<style>" element affects the whole email, including my response as I compose it. As a result, when I press Enter, I no longer see the extra line spacing, and Enter or Shift+Enter results look the same in the HTML version of my email. Yet they insert different content, and in fact the plain text version of the email still adds two line jumps for paragraphs vs a single jump for line breaks, and I cannot tell while composing.

Then, when I send my email, the recipient email reader (e.g. GMail or Office) appears to somehow pick up the difference again, so my paragraphs are displayed again with extra line spacing. This is an issue, because I cannot tell the difference between paragraphs and line breaks, they look the same to me, and I end up using both interchangeably. But they don't look the same to the recipient, and the resulting response looks messed up.

How can I prevent the quoted email from overriding styles in my own response?

I tried installing the CustomCSS addon to add my own "<style>" element, but unfortunately it gets added at the top of the document, and the quoted response's "<style>" element comes afterwards, thus overriding anything I set.

Perhaps the sender's configuration is at fault (they should not use a global "<style>" like this), but they are a customer, and it would not be appropriate for me to ask them to fix their email configuration.

The only "solution" I can think of is to switch to "Body text" as default style, such that paragraph blocks are never used. I think it is a shame to loose this feature, but at least there is no surprises.

Been using Thunderbird for 20 years but never had this issue. I might have pressed some keyboard shortcut wrongly?

My inbox does not show any message, even though there are two of them (and more incoming, there was one when the issue started). As far as I can see, I have no filters of any kind activated.

Any idea how to see the invisible messages again?

Thanks!

Last night I used my Computer and checked for New Emails, before Powering Down. This morning I Powered Up and went to see if an Email I am waiting for has arrived - but Thunderbird is treating me like a Brand New User and asking me to Create Passwords etc. When I finally get to something that looks a TINY BIT like my normal screen, ALL of my Messages and Folders have DISAPPEARED. The last time I used THUNDERBIRD (about 9 hours ago) I just looked for New Messages, and didn't try to make Any Changes, Updates, Archives, Migrations or Imports. Why is Thunderbird treating me like a Brand New User and asking me to Set Up an Account ? How do I retrieve my Emails (both Sent and Received).

Hello.

I read that thunderbird works with Microsoft 365 and modern authentication. I tested with Microsoft 365 accounts and it worked fine. The problems come with an accounting of Microsoft 365 operated by 21vianet service.

I configured according to https://support.mozilla.org/en-US/kb/microsoft-oauth-authentication-and-thunderbird-202 with the IMAP and SMTP settings from https://support.microsoft.com/en-us/office/settings-for-pop-and-imap-access-for-microsoft-365-operated-by-21vianet-ca51235d-afc5-4d7d-843c-3616a37d5771

It complaints "The IMAP server partner.outlook.cn does not support the selected authentication method. Please change the 'Authentication method' in the 'Account Settings | Server settings.'"

In SMTP settings there is no option to configure OAuth2

After updating to the latest Thunderbird I checked my emails and closed the program - but not from the inbox. Now, T'bird insists on opening into that same screen and there is no link to to show my inbox. I have removed and re-installed T'bird with no result. I have tried approximately 15 'sure' fixes from the internet and Mozilla but without success. Finally I read that the new version will open the screen which you were last using at shutdown, but there is no link to open the inbox. There is no link to the inbox on the left side of screen nor a down caret on the right hand side of screen. I have no folders showing, such as "Inbox", "Drafts", "Sent" or 'Local Folder'. I have referred to the Mozilla list of shortcuts without success. My inbox is not empty F5 and Shift + F5 do nothing. The email address for my PC is: albanv@netspace.net.au How can I show my inbox?

Hello, I am using : 115.11.1 (64-bit) The last mail I have received was on 14/06. I have check the POP mail server, I have tried to open at the same time my mail box on the yahoo platform and on Thunderbird. I haven't changed anything and do not understand why suddenly i cannot see my new mails. I can send mails without issue though. Can someone help ? Thank you Sand

All of the sudden my subfolders under Sent disappeared and even the Sent folder disappeared. Plus TB keeps asking me for my password which is a long series of letters, ie. security key. Please help. There was very important info in those folders and I'm feeling kind of desparate. I uninstalled TB and reinstalled. Not fixed at all. Thank you.

While managing my Thunderbird Inbox, I inadvertantly transferred a chunk of Inbox messages received from my MS Office365 Outlook account into the trash. I went into Outlook on the WebApp and discovered that all of the inadvertantly deleted emails were found under recover deleted emails. So within Outlook I recovered all mails into the Inbox. So far, so good.

Now I have all the mails listed in the Inbox on Outlook. But when I open Thunderbird again, the recovered mails do not show up. It seems that Thunderbird does not fully synchronize the folder and the recovered emails are not downloaded. Instead, all mails are once again removed from the Outlook Inbox. The previously recovered mails disappear again from the inbox of OWA and I have to recover them all again.

I have already tried several fixes. Within Outlook, I created a new folder and moved the recovered Inbox mails to that folder. This was done in the hope that this folder will then sync properly with Thunderbird. Unfortunately no. The folder does not sync and as soon as Thunderbird is closed again, all mails are deleted again from the new folder on OWA.

I also deleted the Outlook account (including all stored data) and recreated the account in Thunderbird. Unfortunately, the same thing happens again. The recovered mails are not displayed in Thunderbird and after closing the program, the mails are deleted again in OWA and I have to recover them again. Finally I went so far as to uninstall Thunderbird completely from my computer and reinstalled the software. That did not fix the problem either.

I will also provide another observation: in the past when I have recovered individual emails the same behavior has occurred. Seems that when Outlook or Exchange places a deleted email into the recovery queue, there is a change in its identify such that TB now views it as a deleted message.

Any suggestions on how this can be fixed?

Best regards

Upgraded to the newest version of Thunderbird, 115.11.1 (64-bit) and now I can not get into my emails on bellsouth.net. . Error message "Sending of password for user xyz123@bellsouth.net did not succeed. Mail server inbound.att.net responded: [SYS/TEMP] Server error - Please try again later." I keep trying but same error for two days now. I can get my email on the web (Yahoo mail) ok. I double checked the setting and everything is good and migrated to the new version ok.

I see a preview of new emails that fades after a minute or so. I just saw such a preview, it faded, but when I opened Thunderbird, there is no new email in inbox.

How can I find it?

Also, is there a way to change frequency of retrieving new emails? To create an account for this, I had to get a 6 digit code...it took 4 minutes to appear.

I used the same password I have been using for a long time with my Verizon account and now I get this message: Sending of password for user k.machv@verizon.net did not succeed. Mail server pop.verizon.net responded: [SYS/TEMP] Server error - Please try again later. I can open and download my email messages via AOL but it will not recognize my password to allow me to download my messages to Thunderbird.

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.
