I upgraded to TB 102.0 today. After I checked my settings and updated my plugins, it seemed to be working fine. However, later in the day I noticed a message that TB was downloading about 880 messages in my main inbox. Of course, there are not nearly that many new messages. I searched and did not notice any new emails in the listing. However, I found that two recent messages had been corrupted in some way. I enclosed an image. When I open the message, there is not even the normal header with the different choices. There is just what appears to be a bunch of information that has been mushed together in place of this email. I found two emails like that. I right clicked on the two, and deleted the corrupted messages. Then I compacted files. For a moment, things seemed OK. Some other emails near those that would not display worked again. However, shortly after I did another compact folders, I got the same message -- downloading the same 880 emails. Now I have two new messages corrupted.

Please help! I have no idea how to stop this corruption. This account is hosted on Google Workspace. I have it set to sync only the last 90 days of messages.

I've been running Tbird on Windows for many years. About 2 weeks ago something changed, either in Tbird or at Microsoft, which stops me from sending to the Office 365 SMTP server. I can send and receive using Outlook on the Office website, but I can't send locally from Tbird. Error message screenshot herewith. I have tried every possible permutation of server settings, which currently are:

Server name: smtp.office365.com Port: 587 Security: START/TLS Authentication: OAuth2

MS support says these are correct, and they are at wits' end to understand what is going on. They asked me to ask Tbird support, so I am.

I should add that at about the same time I started getting SMTP rejections in Gmail on my Android phone, and miraculously that was corrected yesterday, without any action from me. There is something odd going on at Microsoft - does anyone know what it is? My other accounts on Tbird work fine of course.

Everything was working fine in Thunderbird for a LONG time. A few minutes ago I opened it and instead of opening normally it opened to a page called 'account setup'. There was another tab called 'home' that had buttons for email, calendar, address book, etc. Clicking email took me to the account setup page again.

HOW DO I GET IT BACK TO NORMAL?????

Every time I download new version of thunderbird I suddenly cannot send emails, I can receive fine. It's so maddening ughh Once this happens I spend many hours searching support and it takes forever to find the answer. Some times it's a simple server setting change is the fix or adding @.... after the username but now this is not working

Please please help

Sending of the message failed. An error occurred while sending mail: Outgoing server (SMTP) error. The server responded: shw-obgw-4003a.ext.cloudfilter.net cmsmtp 138.199.21.216 is listed on Cloudmark CSI-Global. Please visit:// https AUP#IPBL100

My settings are: SMTP port 587 starttls normal password

Server serrings pop.shaw.ca port 995 ssl/tls normal password

Many thanks in advance

The latest version of Thunderbird (91.1.2 (64-bit)) installed yesterday. Before the installation I was able to send emails on all my accounts. After the installation I cannot send emails on any of the accounts.

When I reply to an email, the send button is greyed out. When I make a new email and click on send nothing happens. I can still receive emails. There are no messages that I am doing anything wrong.

I have four separate accounts, each with their own SMTP server. Send doesn't work on any of them. My OS is Windows 10 and is up to date. My antivirus is McAfee LiveSafe (16.0) and it is up to date.

Hi,

I did an upgrade yesterday from 91 to 102. This morning, I get a few issues. Some email messages are blank. Some have a lot of header and content code displaying that is not related to the email I am opening but from a different email message. Some emails have no HTML content but others are fine.

On my cellular device, I am using the Bluemail app and all messages are there and are fine so it appears to be related to Thunderbird 102 upgrade.

I have used Thunderbird for years and this is an issue I have never seen? I am running an IMAP account.

Thanks,

Mike

How do I correct my serious error (when tired) in allowing a Thunderbird 'Upgrade' 115.2.2 (32 Bit) Supernova to install on my Laptop (Windows 10 Home, 64 Bit). I failed to read the Release Notes by trusting Mozilla wouldn't issue such a drastic change without Warnings as it was not just an 'Upgrade'! It has screwed up my Set up, Folders etc., completely changed layout, can't find 'Write Message' tab etc. etc . etc.

The previous Thunderbird Version had many problems further introduced by 'Upgrades' but was at least still had continuity with earlier Versions with a functional MMI (man machine interface) instead of all the changes introduced with the 115.2.2, which in my opinion should be withdrawn completely. N.B My experience in Systems Control, as an Air Traffic Control Engineer, we would throw this out as not fit for purpose.

Help Please and explain how can I revert back to an Earlier Version?

Hello,

I did a clean install windows 11 21H2, installed Thunderbird 102.1.1 and later 102.1.2 in the wizard i copyed my password and all the other info imap, after pressing ready checking password keeps on checking noting happens.

My password is correct and also all the other setting.

Must be a bug in the program.

Hi all,

Just upgraded to Thunderbird 115(from the last Non beta version).

I have multiple email accounts.

When I click to the inbox off one of my gmail accounts it does not display to the last message received. Thunderbird opens to a message about 1/4 up into my inbox.

I have a second gmail account and this behavior does not occur.

I'm sure its a easy fix, I just can't figure it out .

Getting this message as of today when trying to connect to my Outlook/Microsoft Office 365 e-mail account. No change of password or any security settings were done. Googling for the error reveals plenty of other folks coming across it in Thunderbird but not one working fix. Plenty of TB blaming Microsoft and vice versa. IMAP access is still working on iOS so that does strongly suggest a Thunderbird side problem.

Please no "switch to a different email provider" proposed solutions that isn't helpful.

I am running Thunderbird Daily. I had a problem recently where a number of my mail folders got corrupted; mail messages were missing. So, what I did was to restore from a good backup before the corruption the folder and folder.msf files to a new directory. One corrupt folder is my Sent folder. I then copied the restored Sent and Sent.msf to my TB Local Folders directory as Sent-restored and sent-restored.msf (while TB was not running). I started TB and looked at the sent-restored folder. The messages are there, and they are intact. I then select ~2400 mail messages from Sent-restored and copy into Sent. When I look at the Sent directory, I see that all of these messages have been copied, and the directory seems OK - all the correct dates, recipients, and subjects. But ALL of the messages I copied now have the same text - the text of one (I believe) of the messages.

I have tried this twice, with the same results. What can I do to debug/correct this? Thanks.

I have been using Thunderbird for many years and have previously updated without problem. But upon updating to version 102.1.2 I suddenly couldn't see my folders or emails (see attached image). However, if I search for an email I will get a list containing the relevant emails, but as soon as I click on an email in the list I go back to the blank screen like at login with no folders or emails.

I have trawled through related fixes and have tried deleting all of the .msf files in my profiles but to no avail. I really hope that someone will be able to assist.

I can't send emails out of Thunderbird but can receive them, not sure what to do? Is there a phone number I can call with Thunderbird for help? I'm not that savvy with all this.

I have had the same issues with TB freezing and locking up my PC that many here have had. For me, this has now gone on for almost 3 years. I have done everything I can think of, and everything I have read about online to deal with the constant freezing. I have: --upgraded countless times (now on Ver 102.9.0, 64 bit, Win 10, 32GB RAM, 3TB hard drive) --reinstalled Thunderbird many times --deleted various profiles and created new ones, deleted various config files as suggested. --reinstalled Windows 10, upgraded all associated files, drivers, etc. --started Windows in Safe Mode --disabled all add-ons and extensions in TB --reset all toolbars and controls in TB --started Thunderbird in Troubleshoot Mode --gave an exception to TB in my Windows Defender [and turned off Defender entirely] --ran MANY virus scans --disabled ALL virus software

Thunderbird is the ONLY piece of software on this PC that locks it up. It exhibits the same behavior that many here are seeing: freezes when I try to click on something; freezes when I try to reply to an email; freezes for no apparent reason. I can't MAKE it freeze up... it just seems to do it at random, constantly. Right now, it's open on another screen and has been frozen for about 3 minutes, and just unfroze. Most of the time, it freezes so that I cannot shut TB down. It is completely unresponsive. Sometimes it will freeze the computer so that I cannot do ANYTHING... I cannot open Task Manager and force a shutdown. Eventually, it releases and works again, only to freeze up a few minutes later.

I'm pretty much out of ideas, but I continue to browse online, looking for answers. As I said, three years of this is enough, and I see complaints about this going back even further. I love Thunderbird. I'm a longtime user and have not found any email client that comes close to the way TB works for me, so I'm VERY reluctant to leave. But I'm really tired of being a beta tester. And yes, I have donated many times over the years, and I'm happy to do so. I'm not concerned with the money. I just want it to work like it used to. If you have any fresh ideas, I'm very open to hearing them. But a warning, that I have likely already tried the fixes offered. I appreciate any input, in any event.

So, unless a miracle comes along, I reckon I'll have to cut bait and find a replacement for Thunderbird. Thanks for allowing me to blow off some long-held frustration.

best,

Guys hello! I was using thunderbird for my mails on windows 7 on an old machine..Recently it started crashing on startup..I checked for solution on google then i found out i could start with safe mode only...(i wasnt using any addons so disabling them had zero effect)

Because i didnt want to continue with safe mode only, So i zipped my profile folder and created a backup.. Then i downloaded Thunderbird Setup 91.5.0.exe and tried fresh install with deleting the old profile directory...

Now thunderbird doesnt start even with 0 profile..It doesnt start with safe mode too ! I cannot even go to profile manager (thunderbird.exe -p )

I dont know what to do!

I have found crash id but i cannot understand what the problem is! Can anyone help ?

Hello,

I use Thunderbird for all my email addresses, have for years. Never had an issue until today. I've been offline all weekend and have not received an email to any of my addresses since 04/29, 3 days ago. Is Thunderbird down? If not, how can I fix this?

Thank you

I am at a clomplete loss here and after hours of googling and frustration I just need someone who can help.

- I purged all installation folders and paths, deleted profile and reinstalled Thunderbird 115.1.1 on absolutely (!) clean sheet, it is dead on and I inspected all versions and folders.

- I hoped that the version fixes my login issues, but if anything, they're worse and the logins don't last nearly as long as they used to.

- I am aware of the imap, smtp and tls configuration

- I am aware of the settings in gmail, also tried all combinations of oauth2, less secure apps, app password, I tried all of that

- tried enabling javascript manually, cookies, checking all local browsers, especially firefox browser and legacy IE options for anything that could be wrong

- I can set up and add my gmail accounts, usually once upon install. It will then work with no issue, receives and sends mails, loads all sub folders. It just won't stay.

- I can go to account/privacy and view and edit my passwords. I can enter the correct password there and the account itself works and loads mail. If I close and re-open TB, it's still fine. On the 4-5th time of opening and closing, it locks up and starts promting for sign in.

- I get logged out of one or multiple accounts and get promts to sign back in. These login page windows then cannot be interacted with, at all. They are not displayed correctly, the buttons are just dead and do not react or lead anywhere if I click. Some do the little brightness animation and recognize that I clicked, but nothing continues. I have no ability to enter or submit the gmail credentials in there.

- I tried navigating those with on-screen keyboard, CTRL +, also with scroll wheel etc., it cannot be resized or interacted with. Also changing the window and screen scaling size (100%/150%) does nothing, I also checked all actual browsers like firefox and chrome and they all have normal zoom, cache and cookie settings. Why is the login page not usable?

I know it would probably be fine after reinstall but I just cannot keep doing this. It does not last even a week. I even deleted the profile and re-setup everything several times already, it still comes up with login pages all the time. And if those are not usable then I cannot go forward.

This is all on a fresh Lenovo Thinkbook G15 that is nearly new. I have never seen software not work this vehemently. I have given all info that I have and all that I tried. Can someone please advise, I don't understand it anymore.

For approximately two weeks now I am sometimes able to send email in the early morning, but after several hours I receive the error message attached regarding excessive failed authentications. It seems to reset every 24 hours. Comcast has been no help. I am connecting to the Comcast servers through the Charter/Spectrum network at my second home in North Carolina. Since it works sometimes it seems unlikely this is actually a configuration or Thunderbird issue, but I'd love to hear any ideas. Tried disabling ESET NOD32 15.0.23.0 antivirus, no change Thunderbird version 91.5.1 (64 bit), but it hasn't worked properly for several updates, and as mentioned above I don't think the problem is necessarily in Thunderbird. OS is Windows 10, just updated this morning to build 19041
