Thunderbird-Hilfeforum

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)

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.

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

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.

I have never needed to see every single email in my inbox when I first open Thunderbird but I'd assume it trying to load everything is why it freezes for a few minutes every time I open it.

When composing an email and attempting to select an address from the 3 email accounts I use in Thunderbird, I am having difficulty selecting the email address I want to use. I'm clicking on an email address that opens Thunderbird in a compose window when this happens. It is a new issue but has been present a couple of weeks at least.

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

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??

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?

After loading the latest update, I can't send emails. Spamhaus is blocking them. this is an example of the error message... this is a business I have emailed before and they are in my address book, it is doing the same with other addresses

Sending of the message failed. An error occurred while sending mail. The mail server responded: Service unavailable; Client host [68.105.172.193] blocked using an77miiefpoizgkgitohtqs2qa.zen.dq.spamhaus.net; https://www.spamhaus.org/query/ip/68.105.172.193. Please check the message recipient "service@renaissance-printing.com" and try again.

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?

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///

I'm using Thunderbird with my hotmail account and have never had a problem before yesterday. Now I get this error message. "Unable to write the email to the mailbox. Make sure the file system allows you write priviledges." Can anyone advise on this? Temporary email is accounts@gardendesignernorthdevon.co.uk

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?

Hello. Currently receiving the following error pop-up with Thunderbird 115.4.1 on Win 10 22H2:

"Unable to write the email to the mailbox. Make sure the file system allows you write privileges, and you have enough disk space to copy the mailbox."

This occurs when fetching new email from an sbcglobal.net POP3 account. Settings: inbound.att.net, port: 995, SSL/TLS, OAuth2. These settings have worked successfully for years until yesterday NOV 6 2023.

I have several other POP3 accounts all using the same settings shown above but none of them are triggering the pop-up error.

Can an expert please advise the specific conditions that trigger this error so I can determine where the fault lies? Example: Is this Thunderbird's interpretation of an error condition being transmitted by the email server requiring interaction with service provider? Is this Thunderbird's response to an internal problem like not enough disk space? (even though there is plenty)

A solution would be nice, but an explanation re: the triggering mechanism is absolutely required. Thanks.

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.
