So far I used MS Outlook for Calendar and Contacts as well beside to mail. How can I import Those data from Outlook and synchronise with my Samsung A53 mobile (Samsung calendar and contacts) without using MS cloud?

I was editing a contact synced by TBSync from a gmail account.

I created a new note section and added some information that included ":" and newlines.

After saving, only the first line was saved. I tried to edit again to add the information a few times without success, then the entire contact was wiped of information, but still existed.

The blank contact can still be searched by the original name, so something still existed there.

After a restart, the contact is completely gone.

I created a new contact and tried to reproduce the problem by entering similar information, but had no further problem.

Mostly, I just wanted to log this event in case others have the problem.

Hi I was using TB 142 without problems. When upgrading to 143 ou 144.B4 I have problems sending mails to all users after some times. Usually the first mails are sent immediatly but after around 10 mails, I have very slow response (varies from 5 sec to more than 1 minute and sometimes timeout). Usually quitting TB solves the problem but this is very annoying. I went back to 140LTS and sems to have no longer this problem. This was tested on many diffrent networks. I am running under Fedora release 42

Thanks

Since the most recent update, Thunderbird doesn't load the email when clicking on the entry in the inbox, and then when double clicking to open in a new tab, the main window is blank with a Loading... text on the top left, and the URL shown above starts with chrome://

Running Thunderbird 146.0

Since the last update to version 146.00, under the folder Archives, both the sub folders for 2024 and 2025 have changed to Drafts and I cannot change them back to show the year folder (2024 & 2025). None of my other yearly Archived sub-folders are affected from 2016 - 2023.

Under Properties, both show their respective year correctly - i.e. imap://wbriggs1%40sky.com@imap.mail.yahoo.com/Archive/2024 and; imap://wbriggs1%40sky.com@imap.mail.yahoo.com/Archive/2025

I attach screenshots showing the issue and any help would be appreciated.

In essence, after trying various ways of trying to sort the above out, it would be helpfull Mozilla if under the Folder Properties box, I could just change the name back from Drafts to the appropriate year. However, in the folder box when selecting the Name line, it won't allow you to alter the folder name. This would seem the simple solution to any alteration of Folders by being allowed to rename them back to the original name.

I had two emails on my Thunderbird. I deleted one by mistake. The G Mail account still works. I tried to reenter my Spectrum Account and I keep getting that my configuration user name or password are wrong. I checked all settings and they appear to be correct. I also deleted the account and tried reinstalling it and got the same result. I also tried to enter a new email account that I just got. I had the same result. Keeps asking me to reenter the password. (would be helpful if it would say why it is wrong (password, setting, etc.) I spent hours on this today. I worked with the Spectrum agent and we couldn't fix it. Bur it seems to be a general problem because I get the same result with both accounts.

Sending of the message failed. The message could not be sent because connecting to Outgoing server (SMTP) smtp-mail.outlook.com failed. The server may be unavailable or is refusing SMTP connections. Please verify that your Outgoing server (SMTP) settings are correct and try again.

Seem to get this (or similar) error frequently. It's like the things I set randomly revert or change. Have sent images of settings. I certainly don't know what to do.

I am using Version 146.0, released December 9, 2025, on a Win 11 Pro, v. 25H2 pc. No problems until today. Messages won't download from two AT&T (ameritech.net) accounts. T-bird is not asking for mail key. No change after restarting T-bird; same result after rebooting pc. How do I restore email access? Thanks.

since last update my *All Mail* folder is empty but at the top it says there are 138,944 messages. I can use some filters and SOME messages appear but by far not all that should match that filter. any clues? thanks,

I had a scammer in my email. I've since taken the computer to a 'fixer' guy --and they got the intruder out. BUT my read emails are disappearing after a short time. Is there some setting that automatically deletes them? how can I find it and change it??

I want Thunderbird to stop marking everything I delete as having been read. The way it works now, if I accidentally delete mail that I haven't read yet it's much more difficult to find it when everything is marked read even when it wasn't. I searched everywhere and haven't come up with a solution for this. It was reported as a bug years ago and was never fixed.

I use Thunderbird as my email client for my remote machine setup through Parallels Client desktop software for PC. After the recent update, every time I want to send an email, the compose window opens along with another browser window that displays my email account page home screen. Before only the email compose window used to open and after sending the email it would close. Now with the browser window that opens every time, i can't send another email until i close the browser. The attachment that i am including in my email also opens in the same browser window in a new tap and i have to manually close them.

How can i go back to just the email compose window to open and not the browser for every email?

Thanks, Yashar

Hello,

I would like to report a possible issue with the QR code used on the desktop version of Thunderbird to set up or transfer an email account to a mobile phone.

When I scan the QR code from my PC with my phone, the process fails for one specific account. This email address is quite long (36 characters), and I suspect the issue may be related to the address length.

For your information, all my other email accounts (9 in total) were transferred successfully using the QR code, and they all have shorter email addresses.

Could you please confirm whether there is a limitation on email address length for this QR code-based setup? If this is a known issue, is there a workaround or a fix planned?

Thank you for your help.

Best regards, Steve

Hi,

Longtime Thunderbird user. Was online last night, emailing (sending and receiving) perfectly fine. Got online this morning - no changes to my computer or Thunderbird, and suddenly am getting this message:

'Thunderbird could not connect to server inbound.att.net. The connection was refused."

I am able to read mail fine from AT&T Mail via webmail or the Yahoo Mail app. This is strictly an issue with Thunderbird and AT&T.

Any other AT&T users having an issue? Any helpful suggestions? If it matters, I have a bellsouth.net email address.

Thanks!
