Thunderbird Support Forum

I use the global search a lot (when it works!) I don't like the way the results are displayed so I always click 'show results as list'. Is there a way to make that the default way search results are displayed? thanks

I have not been receiving replies to adds I have on Gumtree, to my primary email address, denisj51@msn.com. Gumtree has advised me that my email client, which is Thunderbird, is identifying them as Spam, and is deleting them! I check the junk folder of that account regularly, and they are not sent to that folder. I would like to stop them being deleted. How do I do that ? Thanks for your help. Denis.

I like to keep a few email 'open' tabs available so I can remind myself of important tasks. It seems that the tabs all get discarded when there is an update. How can I keep them from being deleted by an update?

Hello! Since I couldn't find help in the forums, I will create a new question. For about a year now the PC at my work will not open mailto-links correctly. There is no account to select from, the subject has a lock-symbol. The receiver's address is correct though (I replaced it with "address" for the screenshot). This PC is the only one I know with that problem and only with external mailto-links. If I click on an email address inside a mail, it opens it correctly. Thunderbird version 115.11.1 (32-Bit), Win 10

It's pretty impractical, so I am hoping for help. Thank you!

When I launch Thunderbird I get the following message:

Secure connection failed

live.mozillamessaging.com uses an invalid security certificate. The certificate is not trusted because the issuer certificate has expired. Error code: <a id="errorCode" title="SEC_ERROR_EXPIRED_ISSUER_CERTIFICATE">SEC_ERROR_EXPIRED_ISSUER_CERTIFICATE</a>

This could be a problem with the server's configuration, or it could be someone trying to impersonate the server. If you have connected to this server successfully in the past, the error may be temporary, and you can try again later.

Or you can add an exception…

AND Thunderbird then automatically downloads emails without asking me for a password. I have just migrated to a new desktop computer (MSI CUBI 5) and this started immediately.

When I try to send email I get a message telling me my outgoing server does not have a certificate, but this doesn't appear to be Thunderbird's problem?

I'm not happy about any of this? Can you advise me please where I should be directing my request for help? It doesn't seem like it should be a Thunderbird issue, but the address includes the word mozilla so I am sending it to you...

Thanks for any help you can offer, I really like (and support) your software. Margaret

Hello, I have been using TB for a long time wiht no mayor problem. I recently had a problem with the hosting services of 2-3 of the email addresses I use in TB and when I now open TB I can click once on the pop up (say on cancel), but when the next pop up message appears (with the same message but for another email address) TB freezes.

I am using Thunderbird to connect to a personal POP & SMTP server. I have recently migrated to a new desktop and moved the old profile folder to the new computer (so I would keep all the emails). Everything was transferred successfully, including the profile settings.

When I open Thunderbird, I am asked for my password and it all goes well if I enter it manually. If I check the "Use Password Manager to remember this password" box, I am met with a "User to server X with username and password failed" - error and a "Sending of password for user did not succeed" - error. I am entering the exact same password in both cases, yet it only fails when I try to save it.

Hi,

I have been configured my Gmail account in Mozilla thunderbird client version 115.12.0 in Windows 11 system. Have been receiving an error message frequently as below "Unable to write email to the mailbox. Make sure the file system allows you write Privileges, and you have enough disk space to copy the mailbox."

System has enough space and memory and please advise.

I did search for solution before posting this. Couldn't find any recent fixes. Using Version 115.10.1 I have used Thunderbird for years to get various emails. Including 2 different att.net emails. Until about 2 days ago, this has been working well. All of a sudden I keep getting the popup to login with my password. I looked at the password file to see what was being used. Hasn't been updated for years. I used web browser to login to att.net account, confirmed that the pw listed in Thunderbird was correct. I looked at my att account and found that I setup a secure key in 5/21. Not sure what has changed that I can no longer use thunderbird for att emails. Note: I deleted the account from thunderbird and attempted to re-establish the connection.. I used the automated process that TB had for the settings. got an error using the regular password AND using the secure key. I tried setup manually, making sure that the inbound/outbound settings matched. Still won't let me login. Something has had to have changed.

This page did not help. https://www.att.com/support/article/email-support/KM1086159 System config and results screen prints are attached.

Cancelled setup and started over This time I entered the secure id as the password,

I invited someone to an appointment, but screwed up the repetition parameters. I then cancelled that appointment.

The person I invited accepted the original (screwed up) appointment but did not process any emails to cancel the meetings. How can they edit / delete appointments that they did not themselves set up? You can see how messed up the calendar is with the erroneous entries...

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

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

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.
