ever since last update... can't send emails

Send Message Error Sending of the message failed. An error occurred while sending mail. The mail server responded: E5rTxqhwZYbiPE5rUxBTZm DMARC Policy Enforcement: https://postmaster.comcast.net/smtp-error-codes.php#ODM00001. Please check the message and try again.

Hi there I have been using Thunderbird for many years to manage the same many mail accounts on diverse PCs. I prefer using a portable version from portableapps.com, partly because when it comes to transferring to another gadget, it suffices just moving the portable folder, and I do not have to create dozens of accounts in a fresh install. Of late, I have been getting frequent irritating error messages for 2 Yahoo accounts. It connects to them & I can receive mail, but for automatic connections to the server in between, I keep getting error messages like: The current operation on 'inbox' did not succeed.' The mail account to abc@yahoo.com responded: p.', ... etc The other day, after reading about possible solutions from some forums, I decided to just delete both accounts and used the recommended Thunderbird connection settings for Yahoo to create the 2 accounts anew. I thought the problem was solved, only to have the same alerts every now & then reappearing, which amounts to a lot, if you have Thunderbird on many hours a day. I consistently update Thunderbird, the moment I'm alerted to a new version. I also have Gmail, Outlook, AOL(AIM) & other accounts, but not get similar issues. How do I permanently solve this problem? Thank you in advance.

I changed POP3 email password to an app password and Thunderbird would not recognize it even though I updated in Security. I was told to delete the Thunderbird account then set it back up which I did--I did not check the box to delete files. Finally the new account was able to bring in new emails (POP3) but the old folders/emails are not there.

I read that I should go to %appdata%, roaming, Thunderbird but the dates are from years ago--do I go further to find my data or is there another path or something else I should do?

Unless they were backed up somewhere within Thunderbird, I don't think I have any backup.

Can you please help? Thank you.

Please help! Suddenly I can't attach anything to my emails on Thunderbird. Click on Attach, and try all the other methods to attach something, and absolutely nothing happens! Have been using Thinderbird for decades and this is a first. Have gone into Settings, Composition, Attachments and the option Check for Missing Attachments is ticked. Is there another Setting somewhere that could be stopping me from attaching anything? Thank you for your time

Dear Support Team,

Since yesterday afternoon, it has not been possible to attach files to emails using the paperclip icon. Files can only be attached by dragging and dropping them into the email.

Best regards,

I am having constant problems for months now with Thunderbird freezing and message not responding. It appears to happen mostly when trying to empty deleted folder in block like 20 or more. If I deleted in blocks of four all is ok. As soon as I try to delete a larger amount at once it freezes and displays the message Thunderbird Not Responding. I have followed u tube videos to the letter to attempt repair with no success any ideas please?

Hello, I hope you are doing well.

I have asked a number of questions since starting with Thunderbird for Windows 11 a few months ago.

Is there a user manual somewhere? If not, it appears many of us would need one.

Please let us know where to find it or, if there isn't one yet, please create it.

Thank you in advance!

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?

Good day. Can you tell me where to get admx thunderbird management templates and a description of each policy? Is there any Russian language support in admx? There is more information in the official documentation on the use of the polices.json configuration file than admx. Thank you.

Hello, I am having an issue that Emails which are displayed in the reading area disapper for appr. 2 minutes. Afterwards they appear again. I have not been able to find out if this is a problem in Thunderbird, or if another application is causing this. I have read an article that Avast Antivirus is temporarily locking folders during scan. Maybe someone has had the same topic and can give me a hint where to search for the root cause. Thank you.

Thunderbird (157.0.1 (64-bit)) write toolbar missing.

All things are correctly configured, as mentioned in this article, and nothing is working in making the Write (Compose) Formatting toolbar appear again.

Everything is set to compose in HTML format and the keyboard commands mentioned in other articles and so forth do nothing.

Is is perhaps a corrupted profile setting file somewhere? Is there a Config Editor setting that needs to/can be changed ?

Please advise, soonest, thank you in advance.

I have been using Thunderbird for my email for more than 15 years. About once ever few years a corrupted email file prevents me from downloading any more email. In the past I was able to use ftp to list email files on the pop server, find the corrupted file and delete it restoring my ability to download again.. It happened again on Oct 2 but I can no longer use ftp to access the files to fix the problem. IT appears that yahoo has fixed that problem in their email software but Thunderbird does not contain that fix. The bad file is somewhere in the first 4 to 10 files on Oct 2. It follows a file from American cruise lines.in my [redacted]@yahoo.com account using Thunderbird. I now have over 900 email files I cannot download using Thunderbird but can see those files using yahoo email software. Please fix Thunderbird.

Here we go again,I was unable to send email from my yahoo,ca account. I managed to get a password form yahoo and when I re-logged in, all my folders have disappeared. They are still on the webmail version on yahoo.ca, I can now send email though How can I get them back as the folder that the email has: C:\Users\John\AppData\Roaming\Thunderbird\Profiles\a51cb43e.default-release\ImapMail\imap.mail.yahoo-4.com Does not work

I also have Gmail issues for another time

Thunderbird flatpak -1.0 I recently lost the ability to attach files of any kind to messages. when I click the button to attach, no option to choose messages from files are available. I cannot go to the file and share with Thunderbird. I cannot copy a file and attach it. I have tried restarting Thunderbird, and my system (Po_OS Linux) with no result. thanks for the assistance!

Hello,

Is there a method to export my emails in EML format instead of Mbox without using third-party software? Are there any settings in the configuration editor that could change the default Mbox format?

Thank you
