Thunderbird Support Forum

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.

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!

So I've had Thunderbird for a few years. I've always had my (multiple) email accounts set to both check for new messages at startup, and check for new messages every 2 minutes (I keep it open in the background so I can be alerted ASAP). However since the last 2 updates, I can no longer fetch messages either every x minutes, or manually (Get Messages does nothing), and the only way to get new messages is closing and restarting TB completely, defeating the point of having it open in the background.

I've tried: 1) unchecking both 'Check for new messages at startup' and 'Check for new messages every x minutes' = still can't manually pull in mail with Get Messages (the status bar says it's checking, but nothing gets pulled in unless I restart TB)

2) leaving ONLY 'Check for new messages at startup' OR 'Check for new messages every x minutes' selected = nope

3) starting and restarting both TB and my PC = nope

4) checking my antivirus isn't blocking anything = it isn't

5) checking all my email account server settings/passwords are correct = they are

6) testing out Betterbird with the same accounts and seeing if it's still an issue = this also affects Betterbird

7) checking my email accounts are working in other software like Outlook/webmail = they're fine, I can get email there normally

Any ideas as to how to fix this?

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

Name Thunderbird Version 115.12.1 Build ID 20240618125055

IMAP account on HostGator.

In the last 9 months or so, every once in a while (sometimes several times in a row!) when replying to a message, Thunderbird does not set the \Answered flag on the IMAP server.

I enabled IMAP logging and finally caught this happening. The reply is sent and copied to the Sent folder, as it should, but the original email is never flagged as \Answered.

I can't seem to see a pattern why Thunderbird skips this step, occasionally.

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.

Starting a few months ago Tbird suddenly became noticeably slower, and it's only continued/possibly gotten worse, despite several version updates (which I was hoping would fix it). Currently I'm on version is 115.12.1 (64-bit)

I do have several accounts (all pop) and many folders, but nothing different than before the issue began.

I only have 2 add-ons enabled; Remove Duplicate Messages & SmartTemplates. I've of course disabled them and restarted TBird but it didn't help at all.

I've compacted and repaired all folders.

I've created additional folders to reduce the size of larger folders.

The only thing that helped a bit was troubleshoot mode, which definitely made it a bit better going from email to email and folder to folder, and especially with moving emails from one folder to another (which is usually very, very slow and I see it on the bottom saying "moving email 1 of 10 to folder xyz...moving email 2 of 10 to folder xyz...", even if they are simple/small emails). However, sending emails still took over 5 seconds (see screenshot attached), so that might be a separate issue.

In terms of sending emails, whenever I try to send any email it sits on the sending screen for several seconds or more. My internet is fine (2gb fiber, previously 1gb cable), speed tests max out at the 1gb my laptop can handle. Laptop is 2-3 years old high-end Eluktronics, with no other issues.

Given the above, and that troubleshoot mode did seem to help a bit (but straight out turning off add-ons didn't help), what can I try to adjust (while not in troubleshoot mode)?

Thank you very much!

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.

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

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.

On startup TB pops an error box up saying ' There is no email program associated to perform this action'. When dismissed TB continues to open normally. No other errors seen during operation.

I have checked my Win 10 Control Panel Apps options. TB is the email default. MailTo, file type .eml and all other settings I can see are set to TB as well.

I have been using Thunderbird for years with ATT POP3 email. For some reason, it stopped receiving and sending emails yesterday. I keep receiving the error message, "Sending of password for user XXX@swbell.net did not succeed. Mail Server inbound.att.net responded: [SYS/TEMP] Server error - Please try again later." My email is still working when I login to the website. I have tried changing the password and that did not work. Please help.

On Linux, closing Thunderbird also closes Firefox if Firefox was initially opened via clicking a link in Thunderbird. I don't know if this would qualify as a bug, but is there a way to have the Firefox process start independent of Thunderbird when, for example, clicking a link in an email? I'm running 115.12.0 (64-bit) at the moment, but it happens on previous versions as well.
