Thunderbird Support Forum

Hello-

  I recently updated Thunderbird and now I am getting the error message, "Unable to write email to mailbox...". On top of that, when I click the OK button the error window doesn't go away and will not let me use any part of Thunderbird. I have to use Task Manager to close down TB.
 I suspect it is the new update 102.0.1. How can I go back to the last one, 91.10.0 where everything worked?

Thanks, Bob

Hello folks !

I've long time having issues to start mozilla thunderbird on my notebook. It's win10 home single language + norton security ultra. I tried to run "thunderbird -safe-mode" and disable extensions and themes but it didn't worked.

Any light at and of this tunnel ? I'll try to follow here and fix it. Thanks for all attention guys.

Last fail until this message : Crash ID: bp-011d857a-7815-466b-b93e-2a10f0220731

Many of the older messages still in my inbox seem to be corrupted somehow.

When I double click to open the message, it opens a different email showing on the html/jscript body of the other email. For example, links in the html/jscript are for different websites.

1. Could I have set an option or configured this incorrectly? 2. Is there a way to just recreate my inbox without downloading the whole mail userid content?

I'm running on Windows 11 and using the Thunderbird 103.0b1 (64-bit) release.

Any other ideas? Happy 4th to all the American users and developers! ++Mark. https://ctproduced.com

I AM WITHDRAWING THIS QUESTION, AS I THINK I DISCOVERED THAT THE PROBLEM WAS RELATED TO NEW MONITORING FEATURES I ACTIVATED IN MALWAREBYTES. I TURNED THEM OFF AND EVERYTHING IS WORKING FINE NOW.

I believe there was an automatic update to Thunderbird a few days ago, and it looked like an error message popped up, but the message disappeared before I could read it. Ever since then, it's been taking forever to launch. Then when it finally does launch, I initially have a lot of lagging, delays, not responding messages, and even message windows closing while I'm in the middle of typing. It seems to "warm up" after a while and work as before.

Any ideas what might be causing this and how to fix it? I'm on Windows 11.

Thank you!

windows 10 hotspot makes thunderbird and firefox freeze. Other programs continue to work as normal. I can kill firefox and thunderbird via task manager but the apps remain froze when starting back up. Need to reboot the PC and keep mobile hotspot off. Then all is well. Appears to be a bug. Microsoft just says stop using firefox. Have not yet tried that rather draconian option. They would probably advise the same if I reported it with thunderbird Please help if you can. I can use these programs on my pc without turning on mobile hotspot but it would be more convenient not to have to do so. Thanks John Verburg

I am using Thunderbird 102.0.3 (64-bit). I now have vertical lines on the inbox of one of my accounts. When I copy the inbox to the trash folder, the lines follow. The lines look like very small bar codes.

I have attached a screenshot of the issue.

I tried uninstalling and reinstalling, but no joy. I also resetting toolbars & controls, but that did not help either.

Also, I can't customize my toolbars anymore. When I try this, there is only a "hand" mouse cursor, and I can't make any changes.

Does anyone have an idea of what i may try?

Thank you!

I’m having trouble sending mail with my gmail account. Have tried authenticating with Oauth2 but does not seem to work. Incoming mail works fine. Have tried rearranging settings but nothing works. Any help would be appreciated.

Using Thunderbird I upgraded not too long ago (in 2 steps) from Eudora to now version 91.11.0. I no longer see my address books (but see files abook.mab and history.mab (but not the .BAK versions as suggested on the internet)). Both files seem to contain data (when viewed in Notepad). How to get Thunderbird to recognize/use my address books?

I have never disliked an email program as much as I do Thunderbird!!! I thought Outlook was bad, grrr. Sorry for the rant.

Somehow today, my "send" tab in Thunderbird got reset to "send later". Not only will it not let me return to the 'send' default, copying the text of draft messages I created are all set for this too so won't let me copy and paste into a new message in Thunderbird and be able to send that! (I wish I could attach a screenshot of the tab but that function isn't available on the Thunderbird page either!)

So grateful if someone can tell me how to fix this.

(p.s. If Mozilla cares about its users as much as I've always thought it did, surely someone from the company can 'step in' and address the multitude of problems so many of us keep having without resolve? I still cannot open messages properly to read and reply after the last glitch. I'm almost ready to stop using Mozilla altogether ... and that's a BIG crossroads for me because I LOVE the Firefox browser! If anyone from Mozilla is reading this, PLEASE intervene!!! What a supreme waste of time this entire email program is!)

I can not send emails using thunderbird . I have tried to reply to emails, as well as different emails to a variety of recipients I get the following message. Go to https AUP#IPBL1000. I have not gone there, Is this a scam? How do I get back on track?

Login to my Thunderbird account has failed for the second time in less than a month. The first time it happened, the system seems to have fixed itself. This time, it is locked. See the attachment showing the error message. I vaguely remember being advised a few years ago to delete something in my TB and reinstall, that the content of my account is stored elsewhere and would reinstall. Is that correct?

Hi, I have an existing installation of Thunderbird 91.9.1 on my linux system. I have a gmail, outlook and web.de mail each running via this installation (IMAP). My new workmail is hosted by 1&1(ionos). I can log in via web interface. Autoconfig finds the configuration that is (according to their help articles) the correct one to access the Mail via IMAP. Incoming: imap.1und1.de SSL/TLS 993 Outgoing: smtp.1und1.de STARTTLS 587 normal Password Username is my full email address. There have been no typos. I checked 5x, copy pasted, rechecked. Pasted it into the web interface login, and thunderbird before clicking go on each -> tb - no, web - yes domain is talsen.team

I would appreciate some pointers to get this fixed. And yes i did read prior questions regarding this error. It did not help in my case.

Hi,

I have a strange problem with Thunderbird (currently 91.8.1 on Linux, but have this problem for a while). Initially (i.e. after each reboot) Thunderbird works normally but at some point when I start Thunderbird all I can see in the folders list are one entry for each account (see attached screenshot). I can still edit account details. But the only way to make it work again is to reboot my system. Just logging out and in is not sufficient. I tried to start Thunderbird in safe mote or to get some log details but nothing helped or got me a step further.

Today I experienced something new. I worked with Thunderbird and didn't close it (and also didn't suspend or hibernate the system). At some point when I wanted to visit the sent-item-folder I got an error message (unfortunately I didn't make a screenshot) that the folder couldn't be loaded. Then I couldn't open any folder. After restarting Thunderbird I had the problem of above.

Hope someone has an idea how to fix this.

Hello! Using Thunderbird for some years now and very happy normally. Although after trying to send 1 email with a special character "å" in the address, that did NOT succeed, now everytime Thunderbid launches, it pops a dialogbox:

Dialogbox [Unsent Messages] [X Close] Do you want to send your unsent messages now? [Checkbox, Checked] Always ask me when I go online [Send Now] [Later]

Everytime I launch Thunderbird, it now welcomes me with the dialog box!

I have ZERO messages in [Outbox] folder and [Queue] folders. (Is the latter an official Thunderbid folder?) Both are empty. I have repaired ALL folders. I'm always online.

The email was never sent away, probably due to impossible character in email address, and I never saw the unsent email so I have not been able to delete it. Clicking the [Later] button dismisses the windows but then brings the problem back in the future.

Where is the list of log or index of unsent and still to be sent emails? Apparently Thunderbird knows something, despite [Outbox] folder being completely empty!?

I've manually gone offline and back online and sayed online like normally.

PS. read this topic which did not solve my problem! https://support.mozilla.org/en-US/questions/1072963

Any and all help is welcome. Thanks

I have setup my business office mail address with the owl extension. When I try to send an e-mail a error message pops up that Thunderbird couldn't put a copy into the sent folder. So I wanted to place the copy only in the local sent folder, but the settings is grayed out and I can't change anything.

When I look at my personal microsoft mail with @outlook.de I can change everything and the setting is picked correctly out of the box

I have a local folder that has about 950 emails in it and is about 9MB in size. Today, when I choose an email in this folder to view, it just says Loading... at the top and then there is a blank screen below. I have tried Repair Folder. I have tried creating a new folder and moving emails over to it to view them. Same problem happens in the new folder.

The odd thing is... if I choose to view the email in a new tab or in a new window... it displays fine.

Any ideas what I can do to fix this?

Thanks for your assistance

All of a sudden when I try to print my emails from my MacBook Air, they come out all garbled like HTML code. Headers and body copy all come out in code instead of formatted correctly. I've tried everything I can think of to try to correct this issue, but I'm out of ideas. It works perfectly fine from both my other desktop computers. It's just happening with my laptop. I NEED to be able to print my emails from my laptop so I have GOT to get this figured out. Please help!

For several days I get the message "Login to server imap.gmail.com with username alansharp26@gmail.com failed". This seems to be since the following update has been installed: Thunderbird 90.10.0 (20220525135609)iNSTALLED 6 June 2022 , 22..22.43. I can receive emails using Outlook on my laptop, and also on my phone and iPad. I have checked the settings and they seem correct.

Hi!

I often send an email to 140 recipients via SMTP. Until recently it took 2-3 seconds. Now it takes about 2 minutes. My web-hosting company Simply.com is very insistent that their server is not the problem. I use TB 91.7.0 (64-bit) on Ubuntu 20.04.4 LTS. I am not sure whether TB updated itself when the problem started. Any help would be appreciated.
