Thunderbird Community Forum

I use Thunderbird to store loacally some email from gmail and delete it from the online server.

Until october last year it was working flawless, to day I need to read an old email and I discovered that locally since october of some email is only stored the subject and somtime I only have the ticker that increase in the stored email email, but there is either not title or subject. I didn't change any setting in my computer or in the antivirus,, the only thing is that I perform the update of thunderbird as usual. Is it possible to recover these emails or they are gone forever?

Best regards

I will preface this with no I do not have a backup - which is my fault. However I did not expect my account to be nuked into oblivion with no explanation.

As per the title, all my emails are gone. My local folders are devoid of anything I can use and am hoping that everything may be on a server somewhere. This is years of emails, important correspondence, bank information, business, etc. The ONLY thing I can think of is when I download the TB app for android and sync'd it using the QR on the desktop version of thunderbird. I then checked stuff the next day and everything was gone barring emails from that day, all folders, everything was gone. Is there no way to recover this?

Everything has been fine for several years but this morning I now get error: TB could not connect to server mail.twc.com, the connection was refused. Spectrum says everything is good on their end. What do I have to do to "fix" Thunderbird? I can't send or receive any emails from 5 accounts with Spectrum and the emails are there when I log in at WebmailSpectrum.net..

06 May 2026 USA Just to inform users:

All mailboxes and all mail in profile are catastrophically and irretrievably deleted when I: 1. Change the location of the profile folder. 2. Make appropriate change in profiles.ini reflecting the location change. 3. Launch Thunderbird in Offline Mode (launching in OFFLINE mode is the fatal event). 4. Mailboxes will appear during this one launched session

    but

5. If Thunderbird is closed while still OFFLINE, then a re-launch of Thunderbird in any state will reveal

     that all mailboxes and all mail have been deleted.

All mailboxes, and of course, all mail in the profile are catastrophically and irretrievably deleted. I was lucky that I made a backup before changing profile location.

The deletion of mail and mailboxes occur at the close of Thunderbird's OFFLINE state. An examination of the profile folder indicates the destruction has occurred upon closing of Thunderbird in OFFLINE state.

It is not the re-launch of Thunderbird that causes the catastrophic deletion. The deletion occurred when Thunderbird was closed in its OFFLINE state.

To successfully change the profile location I must: 1. Make the change to profile location. 2. Make the appropriate change to profiles.ini 3. BE SURE to make the FIRST LAUNCH of Thunderbird in ONLINE mode--ONLINE only. 4. Once 1,2,3 are done, then Thunderbird does not corrupt the profile folder.

Conditions that MIGHT make my configuration uniquely affected: 1. I use Proton Mail Bridge in conjunction with Thunderbird. 2. My Profile folder is on a network share that is letter-mapped in Windows. 3. I have about 10 email addresses in Thunderbird that are Outlook IMAP, Gmail IMAP, and of course, Proton Mail.

I've been using Thunderbird a couple of years in this configuration with no problems. I just decided to rename my profile. So, this is my first discovery of the problem.

Перестали отправляться письма с почтового ящика gmail.com. Соединение с сервером исходящей почты не устанавливается. Разные порты и способы шифрования уже пробовал. помогите решить проблему. Спасибо.

I have a lot of emails stored in different local folders. My search now hang. They go so far than just hang. Is there a way to rebuild the complete indexing for my thunderbird install?

I just deleted the folder C:\Users\alan\AppData\Roaming\Thunderbird and replaced it with a backup I made a few days ago. To my surprise, when I opened Thunderbird, I could see messages that I'd downloaded today. What is going on?

Trying to sync my outlook and gmail calendars in Thunderbird 140.10.1 and consistently getting an error I haven't seen before: "status.Settings.138".

Hello! Over the last few years, I was using Owl Exchange to access my school and work email accounts which couldn't be added regularly.

Now that I've upgraded, I'm not able to add these accounts using the EWS method. I run into all kinds of errors, or Thunderbird is unable to detect the kind of account.

Yet, my existing IMAP accounts work great with Owl. How can I easily convert these to work with Thunderbird EWS natively?

I have a Postfix/Dovecot server that hosts 10 of my domains from one IP.

When you open Thunderbird, it checks the domains you have preset. I have two. This happens immediately, especially if there is no new mail on the server. Everything works fine.

If you have other domain mailboxes open, and I have eight more, and you click the inbox on each one, Thunderbird stalls at the fifth mailbox, regardless of the inboxes' selected order.

tail -f /var/log/mail.log - confirms this.

I have reset or modified everything I can think of. My server is not throttling Dovecot.

This must be something internal to Thunderbird, possibly related to only using a specific mail server IP for all domains.

Google AI suggests assigning a unique local IP alias to each domain on my server so Thunderbird thinks it’s talking to 10 different machines. This seems extreme.

Any solutions?

Now in v 150, I can no longer modify the tools in the reading pane. Used to be able to but it seems to have disappeared. Of course layout is modifiable but spacing out the tools (so that I don't hit the wrong button in error) or turning some off is no longer an option. The More|Customize does not do much for what I want. Thoughts?

Can I just copy the entire profile folder and name it as a backup or do I have to copy the contents of the folder?

I just want to create a backup to include all my email messages.

Thanks

I set up a new account last week and need instructions on how to navigate and use this forum. I cannot find the question I posted. I got no email saying it was answered. I also need information about these codes I keep getting in my inbox after I've already logged in. I don't know what to do with them. I'm a newbie and need an instruction pdf if there is one. Thanks.
