Thunderbird Support Forum

I have used thunderbird now for about 6 years, for all my website accounts. During that time I have had very few problems, about 9 months ago I started using Windows 8, I transferred all my accounts from my old machines running on XP pro to new machines running Win 8 and thunderbird ran ok. I have auto updates running so I am assuming both thunderbird and windows are updating whenever! About 4 weeks ago I started experiencing major problems with Thunderbird, it would start then freeze, then it would start again then freeze, if I ran it in safe mode it would work for a while. Now it opens and freezes, the message at the top just says ' Thunderbird is not responding'. Even in safe mode now it will not work! I have tried uninstalling and re-installing, I have even tried installing an earlier version of Thunderbird, I Have deleted the profile and forced it to produce a new one, I have spent hours trawling different sites trying to find an answer, and you know what, the only conclusion I could come to was, nobody seems to care whether this problem is solved or not, so reluctantly I have had to give up and I moved all my accounts to Outlook, which works perfectly with Windows 8.1. I think that should have been the answer, right from the start of the problem!

Occasionally Thunderbird email service installed on my desktop is very slow opening an email and loading emails. I have multiple email addresses and it does not happen with all of them. It happens with the two (out of 10) addresses that receive the most emails. What can I do. I thought it might be my anti-virus program but since it only happens on two of the 10 emails that receive messages on my Thunderbird I do not believe that it can be he anti-virus or that would effect all the emails I receive and not just some.

I'm currently running the latest version of Thunderbird with Lightning to utilise my google calendar, since last night, I've been receiving this error message:

"Failed to read 'quotaExceeded' from chrome://gdata-provider/locale/gdata.properties"

What is this error, what causes it and how do I fix it?

For the last few days, Thunderbird stops moving messages to the trash or junk. Also when I send a message, it can't move the message to the Sent box.

If I quit and reopen Thunderbird, it will work again for a while.

I tried "Repair Folder" on the Inbox, Trash, and Junk folders.

Using Thunderbird 24.3.0 on Mac OS X 10.7.5.

Hi,

My Thunderbird is running very slow. I think it is partly because I have too many emails in folders. I would like to back up my emails and addresses and start 2015 with a clean thunderbird.

How can I backup my emails and addresses onto an external hard drive? How can I access them later if I need to read any of them?

many thanks for your help.

Windows 7, Thunderbird 24.4.0

I have been having some issues with Thunderbird not downloading emails. It does not do it even though it is scheduled to do it every 15 minutes, nor will it download email when I click the GET MAIL button. Nothing happens! It does not even make an attempt to download. I know this because the progress bar does not appear and nothing is downloaded even though I know that there are emails in my Yahoo email inbox.

Does anyone know how to fix this? And yes I have already tried reinstalling Thunderbird.

I cannot send or receive emails through my Thunderbird account. It is asking me for a password, which it has never done before. I have looked to make sure that the Master Password has not been activated. How can I reset or remove whatever password is preventing me from accessing my email?

All my emails that were stored in Thunderbird in IMAP don't not load into my Thunderbird Account anymore.

Although I do not use IMAP anymore, and have not used IMAP for the past 7 months (only use POP), all of my old IMAP Emails would automatically load in my Thunderbird Email Software. Several days ago all the IMAP emails not longer are there. I only get a message saying: "

"Alert from account harrison@---------com: full IMAP support is NOT enabled for this account"

My question is ... I haven't been using IMAP for the past 7 months, and everyday all my previously old emails from IMAP was stored in Thunderbird. Now they are gone. Can you help me retrieve my emails. Perhaps they're still saved in my Thunderbird IMAP Profile on my hard drive? ??? I need help retrieving them!! Please help,

Best Regards,

Harrison

When composing an e-mail, in the text area I start typing and the size and font is what I desire. If I stop, click anywhere else in the body of the message, it automatically switches to "Fixed width". I have to backspace or select all text to the beginning of the message and select "courier" again to re-select. Sometimes I just need to backspace over properly composed text and resume typing, but if I start typing in a blank area it switches again. Quite annoying.

Yes, I use "courier" because of fixed spacing which allows me to properly space tables. And no, the tables in Thunderbird are horrible. I'm now running 24.5.0

Yesterday, several other files were bundled with a file I downloaded. I may have uninstalled or deleted something necessary to access my snet email account. Internet access (www. sites) is still mostly intact.

I get my Office 365 account set up and working in Thunderbird. I can download and send mail just fine using the auto-detect or manual account settings recommended by Microsoft/Outlook/Office 365. Everything appears to be working as it should as long as the client stays open. When I shut the Thunderbird client down and restart it, it can no longer access the Office 365 mail account. I get a popup error message:

The current operation on 'Inbox' did not succeed. The mail server for account (my Office 365 account) responded: User is authenticated but not connected.

It has no problem connecting to Hotmail, Gmail and other email services, and I can access Office 365 through the web client, but Thunderbird refuses to connect. If I remove the account and re-add it, I can have full access to my email again, but only as long as Thunderbird stays open. If the client gets restarted, it's gone again.

How do I fix this?

Had a message not load when clicked so I decided to repair the folder, which I might do once or twice a year. Did the repair and when it was done in a second, all my messages in my inbox disappeared. I had around 190 in the inbox and now nothing. I do have a POP3 account and was able to see the messages online, but I need them in Thunderbird. Is there anyway to recover them or maybe re-start my computer to a previous day?

I created an IMAP account last week and I did this with support from my provider. Emails were sending and receiving fine. 3 days ago a message started popping up that the connection was timing out and I couldn't send or receive emails. I went onto my webmail to test the server, but my emails were sending, so it is not the server but my account settings on Thunderbird. I checked the Password, I removed saved passwords, and when I restarted Thunderbird, the same thing happened but now there isn't a saved password nor does it ask me to re-enter the password.

Please advise. Thank you!

The folder Inbox is full, and can't hold any more messages. To make room for more messages, delete any old or unwanted mail and compact the folder.

I get this message when i hit the get mail button dont know how to fix this and am not able to receive my mails.

Hi,

I keep on getting this error: "Sending of message failed. The message could not be sent because the connection to SMTP server mail.domain timed out. "

I uninstall my antivirus program but still I get this message.

Thank you very much for your assistance.

Hello,

I got my organization up and running with Thunderbird several months ago and we've been very happily using it until about a week ago--

We're now encountering an issue in which messages will no longer copy to the sent folder -- the "Copying message to sent folder" progress bar hangs forever, until closed, and then it says there was "An error copying message to sent folder". I have read multiple bug reports but most say the issue lies with the server settings. We several imap (server- media temple) accounts linked to thunderbird, and all are experiencing this problem. On my personal computer, however, I am not experiencing this issue, although the server settings are identical.

This problem began about a week ago. At the same time, thunderbird seems to have stopped allowing us to move messages from our inboxes to our imap folders -- neither click and drag, nor Message-->Move To will allow us to move messages. It will also not allow us to delete messages.

I am running Thunderbird 24.4.0, on mac os 10.6.8.

In the interim, I'm having Thunderbird BCC copies of sent messages rather than storing in the sent folder, but this won't work as a long term solution.

Any help would be very very much appreciated!

Thanks in advance, Jesse and Pistils Nursery

I've used Thunderbird for years. After the most recent update in late July 2020 (78.0.1), Thunderbird no longer works. It will not download new mail. It does connect to the IMAP server but then gets to "checking mail server capabilities" and hangs with the spinning circle indefinitely.

I have not done anything to Thunderbird, I just let it install the update. I did not install updates to any other program on my PC. I'm running Windows 10 on a laptop that is about 4 months old. Thunderbird worked absolutely fine before the 78 update.

I am not experiencing any connection issues or problems with any other running programs.

I have tried the following fixes already: 1. Checking my account configuration and confirming it is correct with my email provider. I have the correct ports listed and correct server names. 2. Changing the timeout setting from 100 to 2000. 3. I am able to access my email on my provider's Web interface so this isn't a password issue. There is no CAPTCHA required either. 4. I checked my anti-virus/anti-malware program (Kapersky). Thunderbird and Mozilla are both listed in the "allowed apps" list. I tried removing them both and re-adding, as well as searching for other variations of Mozilla/Thunderbird to add. I also tried Kapersky's "refresh" function. 5. I tried restarting my computer. 6. I tried rebooting my wireless Internet connection. 7. I tried using Thunderbird's "start in safe mode with apps disabled" function. 8. I tried re-installing 78. 9. I tried clearing caches and cleaning with CC Cleaner.

Nothing has worked. Something in the 78.0.1 update has messed things up. Thank you for looking into this.

Running a new iMac pro here and Thunderbird has been a disaster. I've been using it for years on my PC, and other Mac's in the past. The iMac has tons of ram and plenty of disk space. The system is otherwise idle when using Thunderbird.

The Race condition is repeatable. When it happens, I get the spinning beach ball as the program is completely hung. The only way out is to terminate the process.

Steps to repeat the condition:

1. Open an existing email 2. Hit Reply 3. Compose message 4. Hit Send, and then, quickly, 5. Choose another message to read 6. Application hang

What's happening here is that when a message is being sent, opening a new message before the sending has completed causes a race/hang condition. It is highly repeatable.

Workaround: after hitting Send, wait until it's been sent before moving on to another message.
