Thunderbird Support Forum

I changed the password for one of my gmail accounts and now Thunderbird can't access it. It kept asking for verification. When I realized the problem I changed out the '@' but I can't change the password in Thunderbird. New emails are accessible in Gmail and Outlook but Thunderbird doesn't show then and nothing happens when I use 'get messages'. I need to delete the problem account to re-enter it, when I try to add the email address as a new account Thunderbird just says it already exists and does nothing.

Since yesterday, Thunderbird will not connect to my TalkTalk IMAP mail server unless I switch on a VPN. This is inconvenient. I have no problems accessing my emails through TalkTalk's online mail service, which doesn't happen when the server is down.

using 115.10.1 for emails... each day there are plenty so i pile them up into one place until the folder reaches a size or a date and then we start over. yesterday, the pc updated and almost immediately the search was gone. i would type abc on the search bar and it would take for ever to scan through the messages. then i would click on the email i wanted but something else would open up in the message pane... https://support.microsoft.com/en-us/topic/may-14-2024-kb5037768-os-builds-19044-4412-and-19045-4412-cb676101-1641-4a6c-b512-8b277606c6e3 https://support.microsoft.com/en-us/topic/kb5034441-windows-recovery-environment-update-for-windows-10-version-21h2-and-22h2-january-9-2024-62c04204-aaa5-4fee-a02a-2fdea17075a8

today, i guess, it crashed completely . it started by firing of a warning that not enough space is provided which was not true, then it downloaded 10 messages at once... after a while, the message pane was lost. you click on an email and nothing. it selects it but nothing shows up. blank screen. double click, also opens a new blank tab. fearing a totally corrupt database or even a re-install i pressed repair on the folder. took ages. now, though, i have the profile folder in my PC intact, but TB refuses to load it. i only see the 20 emails i got lately. like starting a new profile all over again...

Whenever i use quick filter to look for email. Thunderbird would tank and massively slow down. Is this common problem or is it just me. Sometimes the performance hit also bleed outside the app and slow the entire system.

Hi, Since 4 days all emails messages ending by ".... @akeonet.com" (SFR company) can't be sent or received via THUNDERBIRD. When opening THUNDERBIRD a password is asked for address email "lalevee.claude@akeonet.com". But the current password doesn't work. I'am getting then a demand to "try again" or "enter a new password" or "cancel" but again without any success. However when trying "Configure your existing address email", I'am getting the message: the email address ("lalevee.claude@akeonet.com") is found in the FAI data base MOZILLA ! Using AKEO webmail, I can find new messages received or can send new ones. Please notice, adresses ending by "...@gmail.com" are not concerned by this problem, and still working !??? Stopping firewalls doesn't solve the issue.

Thank's for your help. Claude

I've had Thunderbird running for a few years now without any issue. Last week I upgraded from Ubuntu 22.04 to 24.04 and ever since that I've been having problems on Thunderbird sending email.

I can receive mails fine but if I try to send emails from any account I get "Sending of the message failed"

I've for 2 Outlook.com accounts and one gmail.com account and all give issues.

GMail I'm using: smtp.gmail.com Port 465 SSL/TLS OAuth2

Outlook: smtp-mail.outlook.com Port: 587 StartTLS Auth: Normal Password.

These settings have worked fine before the upgrade so think there is something broken my TB.

Reaching my end with defects in thunderbird. I select items in the inbox/index of the UI and it isn't updating the email view pane.

Sometimes I select in the index, it highlights the message, doesn't update and then 10-15 seconds later, the UI does a big update like it had hung on something, and it just ignores my selection completely and selects whatever it wants. This is crazy.

I'll add I have a "unified folder" and despite the 3 accounts inboxes included from accounts configured to never auto update, IT ALWAYS does updates whenever it wishes. Again, this is crazy. Like it can't be supposed to work like this ?

So: Is this thing single threaded ? Is the "unified" folder functionality mature and does it work properly ? Suggestions or pointers to fix or research/test what I see is just flat out poor performance when clicking stuff in the UI ?

I really can't believe I'm questioning the basics of thunderbird.

Version is Win 10, 115.8.1 (64-bit), udpating now but I'd say I have found the basic performance to have tanked since the bug UI change to "modernize" it. Seems to me, without exact data to support that I have been degrading ever since. No updates I've made in last few months have improved anything.

Really don't want to leave but I'm about to try using it on Mac and Linux to compare and at same time I just configured all this in apple mail for the first time in maybe 10 years. This is something I never ever thought I'd do.

Last thought, I use same accounts, on iPhone (Boxer) and many iPads. I don't see any performance problems there so I'm pretty confident this isn't the mail servers.

Using Thunderbird Linux for years on my laptop, it sometimes happens that an error message from Thunderbird pops up (mostly because connection problem when I'm in a train or outside, maybe draft can not be saved or whatever).

I just so happens, that when I'm writing an email exactly at this moment and press space, the error message is gone before I had a chance to read it. I could even accidentally answer (y)es or (n)o to a specific question if I happen to press y or n at that moment when the message pops up.

So, not an everyday problem. For me it's happening like a 2 or 3 times during one year. Not quite sure how it could be solved.

Thunderbird 125.0 (64 bit)

This is what the message says. It got hung up after the DONATE message posted. i donated, but it didn't free it up.

"Unable to open the folder Inbox on robert@perless.com because it is in use by some other operation. Please wait for that operation to finish and then select the folder again."

Apple says it is a TB problem, not an Apple problem. Somebody please help.

I am running this computer for my late husband who left us in September after he fell off a 25' ladder at the age of 85. It still has all the information from his art. He was a sculptor who made large kinetic pieces.

Good day Mozilla vols! Has anyone else heard of, or developed an issue recently where TB will not delete multiple emails when selected? Previously, when I selected multiple emails for deletion and clicked "delete selected messages", TB would hang for a bit (while processing), but then all my selected messages would be deleted from both TB and my mail provider.

With timing conspicuously aligning to the 115.10.2 update, the multiple email delete functionality has broken. Now, when I highlight multiple emails to delete, instead of deleting them, TB marks them all as read, and only deletes a single email (the oldest email in the group I selected).

I saw one other question about this, but it was marked "archived" without an answer. Any thoughts/suggestions would be greatly appreciated.

Mail provider: gmail OS: Win 11 Security: Windows Security (old Windows Defender) TB client (now) 115.10.2 Troubleshooting mode (with controls reset and add-ons disabled) did not resolve the problem

My Thunderbird 115.10.2 (64 bit) is lately running very slowly. Message content takes forever to show. Sometimes don't show at all. Sent messages take 20s to save.

I was thinking that my files were simply too large, so I erase everything before 2022-01-01. Where we are now:

  Inbox            13,662 messages 3.0 gb
  All Mail         22,722 messages 5.8 gb
  Sent mail       5,175 messages  1.2 gb
  Important    13,093 messages  3.1 gb
  Other             4,700 messages (approx)

Questions: 1. Can I delete the "Important" messages, thereby perhaps freeing up 3.1 gb? In which case how do I do that?

2. Does this look like too many messages for TB? It's two and a half years worth. Like to keep it, but not at the expense of making the system so slow.

I have removed the databases twice and started with a new instance of TB, which is where we are now.

Thanks for any suggestions!

There is an email app provided by xiaomi on my phone.What in the email sent by this app contains a special format of `Date` fields.It looks like that: `Date: Thu, 2 May 2024 05:55:12 UTC` It doesn't look like others' `Date: Thu, 2 May 2024 06:05:15 +0000` or `Date: Thu, 2 May 2024 10:35:14 +0800 (CST)`

but it is still conforming to standards (or is it only parsable by the JavaScript Date method?)

After I modified windows time zone and restarted thunderbird. all emails changed time so this is not a time zone problem.

But this email shown two different times in the preview and detailed pages at this moment.

So can anyone tell me if this is a bug? Thank you.

Since upgrading to version 115.8.1 I get unable to write email to mailbox . I have three email addresses in my profile. All are POP. One (from yahoo) always hangs and the other two fail intermittently. OS is Windows 10 64-bit at 22H2 level It doesn't matter if Zonealarm is turned on or off. I have over 300GB of free space on disk.

Full error message: Unable to write the email to the mailbox. Make sure the file system allows you write privileges, and you have enough disk space to copy the mailbox.
