Thunderbird Support Forum

Hello, I'm using Thunderbird (and before Netscape Messenger) already 30 years. With this new version 115.4.1 (32-Bit) I'm now experiencing the symptom, that, when I reopen one of the mailboxes the focus is not in this mailbox on the last read mail as it was always in earlier versions, it now focusses somewhere so that you always have to scroll to the point where you have been last time.

The page layout and functionality has changed. I keep getting a message about imap! I have not made any changes to anything. It's just not working, i am very lost with it. Help please. John K-D

Since updating to 115.4.1 under Windows 11 (fully updated), Thunderbird regularly (about every 24-48 hours) freezes up and needs to be shut down with Task Manager. What's up??

Hello, as soon as TB Thunderbird was auto updated to the new version 115.4.1 (64-bit) 2 weeks ago, it keeps freezing randomly but often for several seconds when you click inbox folders from Any Emails I have: Private, Outlook, Yahoo, or Google.

It does also freeze randomly while I write emails or I check other folders. It take so much longer to deal with emails all together.

It tends to do it if the program has been opened recently but also in the midle of the day or while writing emails, for no reasons.

The previous version was also slower but was at least manageable.

What is going on? Any hints or different solutions are appreciated. Best Regards, Chris

I may have had this answered, but my email issues prevented me from seeing any answer.

I use Thunderbird with my gmail account. When I run Thunderbird on my computer, I don't load any emails (I do get emails on my iPhone). I get this error message: "Authentication failure while connecting to server imap.gmail.com." What does this mean and what should I do?

Cannot send or reply to emails. Can receive them fine. Alert message says "An error occurred while sending mail. The mail server responded >jlheiman@charter.net< sender rejected. Check account address settings and try again." Account settings are correct. What do I do?

When I create an email and attempt to insert a link, the message pane will freeze up. Been ongoing for several weeks now. It has forced me to use another client as we can not create any emails with links and that is critical. Version 120.ob1 32 bit Windows 10 PC (no changes made to anything prior to issue.

I need a button to get immediate check of my email inbox from my provider. The old button has been replaced b y a NON-FUNCTIONING button which offers the key alternative alt-1, which also DOES NOT WORK

New installation of Thunderbird on WIndows11 - cannot send mail - get the follwoing error message: "outgoing server smptgo.lanlime.com failed. The server may be unavailable or is refusing connections. Please verify that your outgoing server SMTP setttings are correct." WHERE DO I LOOK TO FIND THESE SETTINGS///

Thunderbird was working great until today... you "offered" me an upgrade to SuperNova 115 after which I am no longer receiving any incoming email. Does not even ask me for the password on startup as the old version did. I have checked the Windows Firewall and added Thunderbird.exe. I need help getting this to work or reverting back to previous version. Also, I recently lost a great deal of pop mail from the inbox and would like to know why - it was telling me I could not Compact the Inbox due to not enough space or not having permissions - neither of which should have been a problem. Please don't make me switch to Gmail!! Help......

Get red error when i write email adresses manually in the To field. Only way to put in adresses is first create an entry in the adressbook and then from the adressbook add the emailadress to the email To fields. Thunderbird version 115.4.1 (64-bit)

I have used Thunderbird for years and I use it for work. For the last two days, it has started to go slow, and it will freeze and I have to close out of it. This JUST started, and this morning it is almost not functional.

I have looked everywhere I could find to see what I can do and I cannot find anything. I even tried re-installing it.

What can I do?

Recent update switched all folder to show messages grouped into threads. This makes it harder to find new messages. As a result I did not see an email inviting me to a job interview for 2 months. Far too late to act on it.

Updates should NOT change any configuration settings. This is NOT acceptable.

Also, I have a lot of folders. There seems to be no way to set them all to unthreaded all at once. So now, I have to go through them one by one changing them back to the way it was.

I needed that job desperately and now I'm screwed. If I don't find a job in the next couple of weeks, I could be homeless.

The irony is that I have over 35 years of experience writing software but I can't find a job because of age discrimination.

Thanks for ending my life.

Hi, I use a old Thunderbird version (38) for Windows Serveur 2003 and I can't connect a Microsoft 365 account. He indicate " A error with login or password" (screenshot in attachment). My password is correct, because it is OK with an other computer with recent Windows and Thunderbird version. I think the problem is with OAuth. Do you have a solution ? Thank you for your support.

I work with my tabs a lot. When I open an attachment, Thunderbird opens a new tab and buts the content of the attachment (pdf) into a new tab. Often I need to save my work and stop working that day, and just let my computer go into sleep mode with Thunderbird still open in windows. In the previous versions, I could just start working the next day, and all my tabs are populated with the attachments and information I left open the day before. With this new update 115.4.2 (32-bit) it does not retain any of the information in any of the tabs that were previously left open. It only happens when the computer has been sleeping overnight or for an extended period of time. If I put the computer to sleep and then wake it up pretty quickly it keeps the tabs just fine. Very frustrating

Hello, Since the update to Thunderbird Supernova from version 102 upwards, emails in several email folders are automatically deleted or hidden. The properties in the respective folders are listed under Retention rules: Do not delete messages.

The emails displayed in the folders no longer correspond to the contents in the folders. Example: A folder displays: 7, properties in the same folder displays: 1226 with 447 MB. It looks similar in the other folders.

How can I ensure that all available emails are displayed in Thunderbird again?

A repair with *.msf does not help.

Many thanks for your support. Erwin
