Forum zhromadźenstwa Thunderbird

Hi, hoping someone could help as I am struggling to get my information back. I am using Ubuntu Cinnamon.

Thunderbird crashed last night, wouldn't work, tried safe mode. Nothing fixed it. It hung when opening up and after 30 seconds said force quit. So I was forced to reinstall. I did a manual backup but not using the inbuilt tool as I couldn't get into Thunderbird. I just copied the data from username/.thunderbird

After spending a long time uninstalling. Because it reached 78% and then crashed on uninstall. Eventually after reading various pages on the internet I managed to reinstall from the Ubuntu software manager using the latest snap version. (Which I am not sure was what was actually installed previously).

However having used thunderbird for nearly 20 years or so. I have a username/.thunderbird folder. And when I moved to this platform, I have a snap/thunderbird/common/.thunderbird folder.

I installed this new distro 2 years ago, and remember having issues getting my data into the system under Snap. But eventually got it to work somehow back then.

However since reinstalling I cannot see the last 2 years of emails, archives or data. It has launched into a 2 year old profile. I appear to have lost most of the emails from the archive folders (but kept the folders) removed all of the personal folders but then dumped all those emails into my inbox. Giving me 6500 emails that were in various personal folders. (I don't get 6500 emails in a year so don't know what has happened.) It has even changed all of the new dates to the US format, so nothing makes any sense.

I now have 2 Thunderbird profiles, over 12GB in size. And have apparently lost 2 years of my life. But reading support pages, suggests I should be okay because thunderbird doesn't delete data when you reinstall?

I have looked through various other threads which talk about pointing it at the profiles and mail boxes, however nothing works.

Any help much needed.

Continuously receiving an alert that my email address (jnsanborn@hawaiiantel.net) in temporarily unavailable. What's causing that to happen?

This issue has existed for a while now. I keep receiving this message on my screen when I send an email from StartMail ( see attached )

This issue does not occur with other providers when using the same client to send emails.

It happens on different computers that has a newly installed operating system and a fresh installation of Thunderbird. The issue is only with the sent folder and only for this email account.

I taken multiple steps to correct this.

Tried installing Thunderbird on a fresh operating system installation and the issues persit

Account Settings -> Copies & Folders. I have tried both Sent and Other.

IMAP is properly configured to imap.startmail.com port 993. This should not matter because the issue is only to the sent folder.

Sent folder set to Syncronized

Sent messages not going into a different folder by mistakes because of any filter.

Properties Repair Folder done

Inside the profile folder under IMAP imap.startmail.com deleted Sent.msf, Sent messages, Sent messages.msf

Click on get messages

.......If I sent an email from the startMail web interface then the email is saved to the Sent Messages but the counter does not show there is a new email

Again the issue only affects mt Startmail account sent folder. All the other accounts do not have issues.

There is a messages that keep re appearing on my screen. Is this helpful ?

The current command did not succeed. The mail server for account ........@startmail.com responded: [TRYCREATE] Mailbox doesn't exist: Sent (0.001 + 0.000 secs ).

What gives I have both a sent and a sent messages folder but no messages are saved and if I am reading this right is telling me that the folder I have does not exist ?

Also I am using Linux Mint 22.1 Cinnamon

A few hours after my initial post I tried another client. Evolution client was configured and worked out of the box. There was no issues with emails being placed in the sent folder.

Is Thunderbird broken ?

I appreciate any help to correct this please. Thanks

I have Thunderbird on laptop. I make changes to a contact in the address book and they seem to be made. When I close Thunderbird and restart it, all changes are lost and are back to what the contact information was before. This has to be fixed.

Thunderbird is deleting emails in my inbox, it only retains 14 days, this is only happening on 1 computer but not on my other one, it started randomly 6 weeks ago, when it deleted over 1000 emails , i know they are on the server because i can access them from another pc. every other folder is fine just the inbox.

Hi there.

I'm in Alberta, where we have recently changed timezones. Note that the CLOCK has not changed yet, as we are still before the date in November when we would "fall back". We were UTC-6 summer and UTC-7 winter. Windows called this "Mountain Time (USA and Canada), but now the "Mountain Time (Alberta)" timezone is in Windows after the 2026-09 Preview Update (KB5124010) (26300.9550).

When connecting to Shaw.ca's IMAP servers, the certificates that were valid prior to the Windows update are now reported as invalid. This has been confirmed across two separate PCs with different email accounts. The data for the certificate LOOKS valid (see screenshot) and is the same before and after the timezone change.

The failure occurred on the latest ESR release of Thunderbird, as well as 156.0 and 157.0 non-ESR.

Thanks :)

Firefox said to update to 153.4.0 esr to continue to use Google Calendar. I did and was able to recover the calendar. But the upgrade lost all my emails and folders. Previous answers for lost emails have not worked. Please give me a step by step procedure to recover my emails. Thank you

Hi, I have Thunderbird installed and have been using it to do my email on a self hosted server and to connect to a google calendar account. This has been working for years, but now I'm finding when I accept a meeting invitation via email, its not being put through to the Google Calendar. I've reset the google calendar link a few time (deleted and created again from scratch). Its using the caldav interface to Google calendar. I'm also seeing this random message pop up (see uploaded image) - but there is no details on what to do. Anybody have any clues?

This is not a question, but rather the solution I found. Sorry if I'm posting in the wrong place, but I couldn't find a better place.

THE PROBLEM I deleted an account. But every time I start Thunderbird, this message pops up in Firefox browser: "Mozilla Thunderbird Email wants access to your Google Account" -- and it's for the deleted account!

I tried all the suggestions I found on the internet, but none of them solved it:

• Add the account again, then delete again
• In Thunderbird Settings - Privacy and Security - Saved Passwords: delete anything with that name
• In Account Settings - Outgoing Server: delete anything with that name
• Calendar: delete anything with that name

Finally, one more thing did it:

• Address book: delete anything with that name;
• even delete address book with no name. Aha! It was this last step that did it.

Hi I am using TB 156.0 (64-bit) on Linux. I guess there was an update t TB and now when I reply or forward an email, the font size of the text is tiny. I also found that the font size for just viewing the body text of an email was tiny, but I was able to fix that. But for the font size in the body of a reply or forwarded email is tiny and I have gone thru all the settings for hours with no luck. Any help much appreciated.

I keep getting "authentication error" when adding a new email account with Infomaniak, even when I use the app generated password. I am not having this problem with Outlook. I cannot disable Account Hub (1 suggested solution) in Thunderbird 157. what to do?

I'm running the current 157.0.1 release on Windows 11, and specifically am having my emails from the AP be sent to spam even though I have a specific filter set to tag them. I feel as if the filter itself is set up properly because when I manually run it the messages will be moved from the spam folder to the inbox and tagged accordingly.

The one thing sticking out to me is these emails are being forwarded through my relay account. I've tried changing the filter to work based on the relay address, but again it only works when I manually run it. I've also tried setting the filter to run both before "and" after spam classification, but neither option works. Ideally the filter would work without me having to go to my spam and run it, and even then I'm wondering why the spam filter hasn't learned by now that those email belong in my inbox.

I'd appreciate any help or solutions; I'm not an email power user or networking wiz though so please try to keep it as dumbed down for me as possible!
