Thunderbird Support Forum

Every few days, the index pane of some folder gets corrupted. Repair (right-click, Properties, Repair Folder) fixes it. Then a few days later this repeats, with a different folder. I have three IMAP accounts and this occurs on more than one of them.

Any suggestion for finding and fixing the underlying problem?

I have not had access to my email since the April 18 Thunderbird update, receiving this error message: "After changing password on an IMAP account, the account could become locked due to too many failed login attempts" How do I fix it? Please email me at jjhpor@gmail.com because my primary email, using Thunderbird, does not work (See above) Thank you Jim Housman

Hello, I am trying to send emails from my iCloud account and it always fails due to the SMTP server timing out. I've tried making a new app-specific password, deleting and re-adding the account in Thunderbird, and made sure the authentication settings are right, but it still doesn't work. I can connect to the IMAP server just fine.

I have been struggling with slowness in Thunderbird in recent months (Windows 11, mid-range Lenovo laptop). There is often a distinct lag during even the smallest operations.

Examples are: selecting an email, closing a tab, typing, calendar events editing.

TB process in Windows usually uses 1000MB RAM. RAM is around 60-70% usage usually. I never have the same slowness issues with other applications.

I tried quite a bit: safe mode testing, removing extensions, compacting folders and more tips. I ended up removing Thunderbird and my profile entirely, and reinstalled the latest version with an empty profile. I just set up my Gmail and other email account. No extensions installed, yet still the same issue.

Could it be that something is still there from a previous install, if I removed my profile?

I've been using Thunderbird in Linux and Windows for years with moderate issues that I was able to resolve, but am now really puzzled. Please help.

So running thunderbird 115.10.1 (64-bit) and more and more issues:

• the app keeps getting non-responsive for long period of time, to fix this I have to force quit the app.
• at times when composing an email the app freezes where no typing occurs for seconds or typing is very slow or after typing awhile the text suddenly appears.

Seems to be happening more and more trying to figure out how it can return back to it's rockstar state when it was <99 version.

any help would be appreciated.

Just switching between inboxes can cause up to a 10 second delay with Thundebird "not responding" with the spinning wheel. It has been like this for the last few laptops I've had and through all the updates and I am getting ready to call it quits. I did a performance recording of me just clicking through the different folders and then it locks up on one. You can see it here https://share.firefox.dev/3WlrRi9

I am using a primary gmail imap account, an office 365 imap account, and another imap account from an ISP.

On Win 10 LTSC, CPU: 16 x 11th Gen Intel(R) Core(TM) i7-11800H @ 2.30GHz @ 2304 MHz 10240 KB Cache, MEM: 65277 MB, 60% (39120 MB) free, GFX: NVIDIA GeForce RTX 3080 Laptop GPU 16192 MB

Today, most of messages have suddenly disappeared from my TB inbox, leaving only the most recent 105 out of approx. 18,000. I have not performed any operations (compacting, archiving...) that could have caused this.

I immediately invoked the 'Repair Folder' command, which did not resolve the problem. Further investigation revealed that the 'Inbox' file ('Profiles' folder) actually contains only 105 messages - seems like the 'Repair Folder' truncated the file!

Fortunately, all the messages are still on the server. My question: Is there a method to 'force' reloading of the missing messages?

Thanks, Ray

I get this Error message when I try to send emails from my outlook email address in Thunderbird. Basically asking me to enter a Password to login to office365 server ! My Password is correct, and has not been changed recently.

Any ideas please ?

Using 115.10.1 and POP on Windows 10 Pro (v. 22H2) with just the Windows built-in virus protection enabled (but App or Browser Control is disabled). Platform seems stable, no evidence of nefarious services noted in task manager.

Realized the emails in InBox from a couple of days ago (and going back decades) were blank or had mismatched headers to content. Figured an index problem. Ran the Repair under 'InBox' folder Properties, and only a few of the most recent emails remain - all duplicates of which I had sorted into other folders.

All the other folders are fine - just my InBox got wiped! Looked in the Thunderbird folder under profiles and saw the above captioned with a time-stamp that captures the approximate time this went down - occum's razor. I did not initiate any update to Thunderbird.

Walking on eggshells and very nervous, we're talking thousands of emails, what is the recommended recovery of the InBox (after I attempt to backup what I have left). Thanks!

Hello

Yesterday there was update in Thunderbird and went well. But today, Thunderbird suddenly asking for credentials and then it went totally blank as in screenshot. There is nothing at all. But incoming mails are still showing up in windows notification and it can be opened as new tab of Thunderbird. I have been searching the possible cause and solution from forum and internet, but no luck. Can someone please help me about this ?

how can i stop thunderbird from interacting with windows defender anti virus scan? when ever i download or delete emails i get a few seconds of "not responding " and the whole computer is non responsive. i used to be able to turn off real time scan in security and it would work for a day and then windows would enable it again. now since the last upgrade windows isnt allowing me that option any more. solutions?

Hi. When replying to an e-mail, Thunderbird has started to place to input cursor in the TO field instead of the message text field (in this case it should be before the answered text).

Any ideas? BR Johnny

I'm trying to use Thunderbird to access my work emails directly. They use Outlook Office 365, which I can use the webmail version of just fine, but a year ago they upgraded to Oauth2 and MFA and for the life of me I cannot get any version of Thunderbord to work with it anymore. I can send an email, but I can access any email on the server. Weirder still is the error console message suggest the program thinks I cancelled my password entry;

"Loading failed for the <script> with source “chrome://global/content/netError.js”. neterror:128:4

NS_ERROR_ABORT: User canceled primary password entry"

Thunderbird on my top of the range Win11 laptop was working perfectly until it self-updated to 115.10.1 a couple of days ago. Accessing messages already in the various folder is fast as usual. Unfortunately anything like deleting, downloading a new message is excruciatingly slow : several seconds to click and delete in the inbox. Several seconds to access a message just downloaded. The first time it happened I had a whole bunch of messages deleted because the I kept clicking when I saw no action. It seems to me like it has problem updating the messages in the inbox. Very painful for something that was working so well.

I am asked to get a new password from my mail server (AOL) every day when trying to send messages. Have to log on to AOL, ask for app password, enter at Thunderbird. DAILY!

Yesterday my Thunderbird was sending but NOT saving sent messages. I was receiving all messages. Today, however, I CANNOT RECEIVE or SEND messages. I have used Thunderbird on this computer for years . . . what has happened?

I would appreciate your help. Win Dawson
