I have three POP addresses configured but TB will only send through the default account. If I select the "From" address to be different than the default account, I get the following error. Once I change the default account to the one I am sending from, the email sends fine.

Error: Sending of the message failed. An error occurred while sending mail. The mail server responded: SendAsDenied; mail1@outlook.com not allowed to send as mail2@outlook.com; STOREDRV.Submission.Exception:SendAsDeniedException.MapiExceptionSendAsDenied; Failed to process message due to a permanent exception with message [BeginDiagnosticData]Cannot submit message.

I cam getting constant and continuous multiple security exceptions for p53-caldav.icloud.com saying it's the wrong site. I have made not changes to the thunderbird setup except for normal updates. i've confirmed these multiple times but they still keep coming. Any help would be great

Hi there, I use iPrimus. I can Receive emails. I am currently based in Thailand (previously Australia - no issues)

Whenever I attempt to send an email from Thailand, I get the message: "Send Message Error Sending of the message failed. An error occurred while sending mail: Outgoing server (SMTP) error. The server responded: smtp692.syd.oss-core.net."

Outgoing Server Settings: smtp.iprimus.com.au Port 587 (default) - (NB I tried 465 without success) Connection: STARTTLS Authentication: Normal Password

I am viewing my emails, and I can see that some emails are not nesting properly. It doesn't happen all the time. I am expecting all emails in the thread to have the same subject. Please see screenshot.

We cant download emails in thunderbird any version with mailboxes on exchange online O365.

SMTP works fine. Receiving mails is not working and it gives Retr 21 error.

Thunderbird had been working perfectly for years under Mac OSX 10.13.6 (High Sierra) until this morning. Now attempts to start it result in an error message "You can't use this version of the application 'Thunderbird_78_10_0.app' with this version of MacOS. You have MacOS 10.13.6. The application requires MacOS 10.15 or later." The app shows a modified date of July 12, 2024, i.e., this morning and a size of 434.7MB. Perhaps it auto updated itself without checking that the update was compatible with the environment? Any suggestions about how to reverse that update or otherwise fix the problem would be appreciated!!! Garth Fletcher

Cox just transferred all customers' email systems to Yahoo. After my e-mails were transferred to Yahoo, Yahoo tried to help me when I was getting error messages saying that log in to server smtp.mail.yahoo.com with my user name (my e-mail address) failed. The Yahoo rep told me that my problem is that "Whenever the generated app password from Yahoo is entered, sending emails works, but it only stays like that until the computer gets restarted. The app password is not saved." The rep told me that many Thunderbird users who had their email systems transferred to Yahoo are having the same problem. Has anyone had this problem and been able to resolve this problem? Thank you! Cyd

I'm running Thunderbird 115.12.0 64-bit on Ubuntu 22.04. I recently had a hard drive crash. I've had to put together my email data from two separate backups to restore everything. The problem is I reorganized the mailbox folders between the backups, so the metadata thunderbird maintains about the data storage will be wrong in my new setup. I have my imap and pop mailboxes restored correctly now under my profile storage and would like Thunderbird to just leave them alone. The problem is, every time I start thunderbird, it automatically wants to compact my mailboxes and free up 5.7 GB of space, which means it will delete some of the newly copied emails it doesn't recognize.

Is there a way to tell thunderbird to start over and reindex the mailboxes that are there? I've tried deleting the global-messages-db.sqlite file, but that does not fix the problem. This is a common problem as I've had it happen in the past as well when reorganizing the folder structure. It seems there should be a way to tell thunderbird to reset its indexes and leave the mailboxes as-is.

Any help would be appreciated.

Today I changed my Google password, and now I can't login via Thunderbird to get email.

On startup, I am prompted with the Google login screen, which asks for my email or phone. I click Next, and get the message

   400. That’s an error.

   The server cannot process the request because it is malformed. It should not be retried. That’s all we know.

I'm using Thunderbird 115.10.1 (64-bit) on MacOS Sonoma 14.5.

After update Thunderbird to version 128.0esr-3 (Ubuntu, snap) RSS channels that require authentication are not downloaded. There is info about access denying.

In previous versions there was a pop-up asking for login and password (no need to write, just click button) after every restart od Thunderbird. Now there is no pop-up, only info about denied access.

I have contacted you previously and tried all the suggestions to solve my problem. None of them seemed to work. The issue only arose after a recent update to Thunderbird. I was pointed in the direction of my service provider. They confirmed nothing had changed their end. I created an email account in Microsoft Outlook. I can send and receive emails via my service provided. I have to assume the problem I am having is with Thunderbird. Before I leave Thunderbird for pastures new, do you have any suggestions? Bill

My "Write" screen has suddenly become useless. It will not show any toolbars, including the Composition bar. So no Send button, no sending. Even the formatting bar below the subject line is grayed out and inert. Looks like this is a longtime failing. I tried solutions offered in earlier threads and none helped. Pressing Alt on the keyboard does not produce a temporary Menu Bar. Help!

Hi, Recently Kaspersky antivirus (Premium) started picking up potential threats. It points to files in C: users\lther\appdata\roaming\thunderbird\profiles\tzldd93i.default\mail\pop3.iafrica.com\sent....

I have deleted the files in Thunderbird under sent files, but they still get picked up by Kaspersky. There is no option to delete them in Kaspersky, only to exclude or ignore. I do not want to manually delete all sent files, I cannot see the individual files in windows (win 10) anyway.

Is there a way to fix this. Kaspersky support have tried but no success.

My laptop using Windows7, the processor died. The hard drive is ok. I am now using Windows10 in a newer laptop. I don't know how to access all the data from the other. I don't think I did a back up. I've got both personal & business. Is there a way to retrieve my old Thunderbird info? [And just so you know, I learned my lesson about not backing up.] And thank you for any help!

Thunderbird 115.12.1 running on Windows 11 in S mode. Working fine for several months, until today my wife clicked on a particular message, then Thunderbird hung, displaying a tab with "Loading" and the path to the inbox and message, and not responding to any user actions. Killing Thunderbird and restarting results in the same situation. Thunderbird is trying to start up where it was when it was killed. It appears that something in the message causes this problem. I have tried the following:

• Tried to clear the startup cache, which I am able to access by bringing up the "Write new message" window. However this action starts the main Thunderbird window, which immediately hangs. Also tried starting in Troubleshooting mode, with the same result.

• I tried to navigate to the Inbox in Explorer, hoping to delete the offending message. But under AppData/Roaming, I saw only two folders (Adobe and Microsoft), but no Thunderbird folder. I made sure to unhide hidden files in the Roaming folder, but it did not help. I also tried this as the user (me) who set up the system and is presumably more privileged but that did not help. I am not knowledgeable enough about Windows 11 security to know how to overcome this. It seems like some kind of super-hiding that only Thunderbird can get through ??

I can try deinstalling and reinstalling Thunderbird but would like to get some thoughts on this before I go that route.

Thanks

I have used "All mail" option in Search Messages window to search and store in a local folder emails which were: - received recently and are unread - received in the past 7 days - sent in the past 7 days

Since yesterday (2024-07-17), the local folder (and subfolder) for them emails received (both unread and within 7 days) has disappeared. The one for sent is still there.

Most importantly, there is no option "All mail" in the Search Messages windows.

For the steps I have already tried, I have multiple email accounts within I need to search. And Global Search is activated. I have TB 1 profile. I have deleted the global-messages-db.sqlite and re-created it.

Thank you in advance for your help
