For a few weeks now we have been unable to send emails through tbaytel server via Thunderbird. We get SMTP error. This happened after recent upgrades to Mozilla. Any idea when a fix will be out?

My inbox is not updating for my personal or work account. I recently reset the password for my company account and since then I have not received new emails on thunderbird.

I moved some emails to a folder and they are not there. Tried to move last email to folder and it jumps back to my inbox. Also how do I access help in thunderbird?

My @googlemail.com account has been working in Thunderbird for years. Two days ago it stopped. No incoming e-mails and attempts to send e-mails from Thunderbird result in the outgoing server timing out. I can access direct at gmail.

Please note that my previous e-mail: alan.rhodes@talktalk.net is no longer available The replacement: alan-rhodes@outlook.com has been blocked by MS-AI (It didn't like a circulation e-mail to 60 members of my local history group) The only working e-mail I have is the current problem one: rhodes.alan1@googlemail.com

I get "connection to server pop.mail.yahoo.com timed out" every few minutes. mail is not usually delivered, and some mail that's delivered is from two-three weeks ago that I've already gotten. It seems that I've stopped receiving mail for account "redacted@frontier.com" after 10/8/26. Mail that's sent to other accounts seem to be delivered OK, but mail that's sent to this account doesn't show up. I've received at least some mail for account "redacted@frontier.com" for 10/9 and 10/10. Not sure if I'm getting everything. Mail seems to be received at the yahoo.com website for both email addresses [redacted@frontier.com and redacted@frontier.com]. At least I hope it is! Mail also seems to be received using the yahoo app for Android [phone] and yahoo app for iPad.

Kan ikke modtage og sende mails. Får følgende besked - Kunne ikke skrive mailen i mailmappen. Sørg for at du har skriverettigheder til filsystemet, og at du har nok diskplads til at kopiere mailmappen.

I haven't had my new email downloaded from my Yahoo mail accounts since 10/8/26. Occasionally, a few emails appear, but they are duplicates from earlier dates, as far back as about 9/27 or 9/28. I have emails from a gmail account that I appear to be getting in T-bird normally. Email seems to be getting through ok on webmail (Firefox, Windows 11). I'm also getting mail on Android (Galaxy S23, Yahoo mail app) and on iPad (also on Yahoo mail app.)

I have 5 Gmail accounts they r all configured the same I automatically let thunderbird install two but none of the other three will not connect i have tried everything i can think of but to no avail

Hi, my mozilla has just stopped dowloading messages to my laptop. Oddly, any messages sent seem to be received, and a test to my phone to myself verifies. Any suggestions please I would be most grateful for!

Hi I have four IMAP email accounts configured in Thunderbird. Three get email from my servers the fourth from Google mail.

I am finding that one of the accounts emails are also ending up in Google mail, the other two are functioning normally.

I have checked for email forwarding etc and cannot find anything.

I removed the account, leaving the Gmail account alone, from my mobile and the phenomenon stops till I fire up the PC.

Anyone got any ideas?

For some strange reason, I have one message in my inbox that does not display in the window below it (just a blank window) and the message subject line can not be deleted at all. Message title has been there for a week now, shows up every time I start Thunderbird but it can not be displayed or deleted. I have received, read and deleted dozens of message since, it just remains as if haunting the app in defiance of any common sense at all. How do I delete it?

The image shows the message selected and the blank window below, once I select another message and then go back to this rouge message, the previous messages window remains, the blank window does not come back up, Indicated to me that there is nothing in this rouge window to be displayed, hence it is blank if the first message selected.

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)

A couple of days ago I was suddenly unable to receive email. I can still "Send." This may be relevant. A week or so ago my ATT email started requiring a verification process that required matching up figures. This continued for several days. Eventually I started receiving a "verification confirmed" message w/o having to match the figures and the log-in proceeded as usual. For the last couple of days I have not received the verification message and the log-in as proceeded in the normal manner. I remember a few years ago there was a problem with ATT and Thunderbird having to have a special pass word. It was called a SafeKey. Don't know if this is the same problem.
