I swap computers about 3 times in year, and not all of mine emails seen to have transfer. I was wondering if there is any way I could potentially recuperate those emails.

Hello everyone. From time to time, the "Attachments" button stops working. It can be clicked, but nothing happens. Occasionally, restarting the PC or the email client helps. More often, the only solution is to reinstall the entire program—which also means losing access to years' worth of emails, as I then have to wait for them to be re-downloaded from the IMAP server. What should I do? I’m using the latest versions.

I'm getting a popup error message saying "Unable to write the email to the mailbox" on one of my gmail accounts. This has happened a few times before and I'm not sure how I managed to get it working again those times, seems hit-or-miss. I've compacted and run a repair on the inbox folder several times as suggested by others. I've updated and restarted Thunderbird and even updated windows and restarted more than once.

Windows 11 Pro Thunderbird 158.0 (64 bit)

I'm attaching a screenshot from the Error Console (Tools -> Developer Tools -> Error Console)

As of Oct 12 2026 I also have this issue. About a week before the 12th I was getting messages that I needed to sign into my RCN account which I would do and it just kept asking me. A few times each night to start then right before it shut me out I had over 50 of these messages just flooding my screen. I never did get a screen shot of that message, but did for the 2 error messages I got later once it shut me out. I shut down my computer the night of the 11th then when I signed back in on the 12th I could not send or recieve any emails. SOmething similar had happened before, but when I shut down again it went away. This time it did not. I then tried to access my emails thru the webmail I can access, but that also had shut me out. I also tried my tablet, a borrowed smart phone, but I could not access anything for my emails. I troubleshooted with my email company and my internet company, but they found nothing. Then I shut off the wi-fi on the smart phone and bin go I could access the webmail. But I still cannot find anything on what to do to fix this. I use RCN for my email, Spectrum for my internet. It is a POP3. Running Thunderbird version 153.5 Oesr (32 bit) Meadow, which says it is up to date. I have norton 360 anti virus & do not use VPN. I disabled my Auto-protect and firewall on the Norton and that did not change anything. I have sent the error messages to RCN and also troubleshot with Microsoft and had some hints, but nothing has come of that yet. Here are the screen shots of the only 2 things I ould capture. The error message was when I was trying to access my email thru Thunderbird. And it came up every time I tried to send messages, not that does not show up anymore and nothing happens when I try and send anything. The second one was when I was trying to access the RCN webmail and it would not let me in on anything I used. Until I shout off the WI-Fi. Then the smart phone could access my webmail account.

Haven't been able to get into Thunderbird since 9/26/26, every time I try it keeps asking me for my password. I key it in and it does the same thing. I have had someone to come up and look at it, but they weren't familiar with thunderbird, I have been having to use Kinetic email, don't like it. hate gmail.

Dear Support

Kindly help me in solving the problem of not being able to attach files in my Thunderbird emails. Thank you Yours sincerely Ana Cristina Figueiredo

I received an email from Thunderbird (my email provider) wanting me to join the Early Bird Beta but their link to pay with PayPal didn't work so they requested I add a new credit card. I use PayPal often so I know my card on file with PayPal is OK. Seemed odd to me for their request. I could forward their email to me if needed. Looks like they are using Paddle.com Market Limited.

I was using Thunderbird 153.4.0esr 64-bit and my send feature on GMail stopped working. It just spun and spun with no connection.

So, I removed the GMail account from my accounts list and then tried re-adding it, but only received the following error (see image attached). This implies what? I have an account at GMail already? I have a remnant of the previous working account in my configuration? It was working fine until today.

I'm using the automatically derived ports (993 inbound and 465 outbound). That error message appears immediately after having clicked the "Continue" button.

Recently I updated Thunderbird. When it rebooted, all my emails in the INBOX and ARCHIVED folders were gone. I have tried the usual solutions, including REPAIR FOLDER buttons. Those archived messages were important. Any chance of finding them?

I keep getting the following (see attached image) when I try to open my Thunderbird. I tried to unsuccessfully open safe mode because it still asks for a password from my very old BlueHost account. I previously worked with AI on this and deleted all BlueHost lines I could find in my account. View the image I have included and see all the messages that include BlueHost. They must be hiding somewhere in Thunderbird. I am not sure what version I have because I cannot open it. Please help! I be happy to send you my phone number is needed.

Hello,

I'm moving to Graph from EWS and have followed the instructions at: https://support.mozilla.org/en-US/kb/microsoft-ews-graph-migration

I get through to screen that offers Graph API as an option, alongside IMAP, POP3 etc, and click on Graph API which directs me to my browser to log in to my email service (via GoDaddy). I log in successfully which takes me to the Thunderbird 'You're All Set' screen saying the account has been securely connected to Thunderbird and therefore ok to close that screen.

Back on Thunderbird it then progresses but returns with "Authentication Error - unable to log in at server. Probably wrong configuration, username or password".

The username and password are correct, and there aren't any other options available when editing/manually configuring the connection...so at a dead end, alas.

Any pointers much appreciated!

When editing a contact in Address Book, after selecting a time zone from the drop down menu and saving the contact, only the first 7 characters of the time zone string are displayed in the contact view. When reopening the contact for editing, the time zone field is shown as empty again.

I have been getting the following error message each time I log into my email today: " The STAT command did not succeed. Error getting message number and sizes. Mail server pop.bluedomino.com responded: [SYS/TEMP] Internal error occurred. Refer to server log for more information. [2026-10-14 12:31:46]" I get a message for each of my email accounts. My spouse also gets the message on hers. The server we use has just been transfered from Blue Domino to Network Solutions.

A week ago my sent emails were being rejected and the error message included something about bluehost (I called them and it was fixed within the day). Now it's happening again and my error message says:

host eig-east.smtp.a.cloudfilter.net [3.228.35.199]

   SMTP error from remote mail server after end of data:
   550 Connection Rejected - see http://www.spamhaus.org/query/ip/162.241.218.139 AUP#BL

I receive emails yo simon@padworks.plus.com, but cannot send them, with a message saying ...

Sending of the message failed. An error occurred while sending mail. The mail server responded: Unknown sender. Please verify that your email address is correct in your account settings and try again.

please also reply to simondowthwaite246@gmail.com

At Thunderbird > Settings > Privacy & Security > under Passwords > "View Saved Password", the dialog box pops up correctly. But the size of the box is so small the columns can't display the complete info i.e. username, password, or date. When I hover on the column divider I get the left/right sizing arrow but nothing happens when I click & drag the arrow. I am on Thunderbird 159. Thanks.

Trying to attach a file to an email, the "attach" button opens but doesn't react choosing "file", where the function worked seamlessly before. What can I do? - Many thanks for hints!!
