Hello,

Everything working just fine last night. Wake up and Thunderbird will not retrieve emails.

Remembered this old message I got so I went through and deleted my second email address, didn't help.

https://support.mozilla.org/en-US/kb/thunderbird-and-yahoo

Checked all settings compared to Yahoo, still won't download messages. I can even send a message with my current settings no problem, and it does login, just won't retrieve emails. Gives me a connection timeout.

Anyone have any ideas?

I have a filter setup to forward certain emails to another account. It has been working fine for years. Suddenly today I am getting an error message about not being able to contact the smtp server. If I manually forward the email to that same address it goes fine.

Guten Tag, wie kann ich Einträge in "Täglicher Spambericht Mailbox....", wieder herstellen. Es wird immer nur die Mailadresse des Absenders angezeigt, nicht die Nachricht. Danke für eine Rückmeldung. MfG. K. Artschwager

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.

I'm trying to upload less than a gigabyte of images to my send storage but am getting the following error: "you don't have the key to decrypt this container"

This is my own storage space.. I've already generated my own key. Why would it be saying this? I see there is also supposedly an option to upload/share files via send natively in thunderbird via a dropdown menu from the "attach" menu, as show here in the list of features. However, this option doesn't appear in my thundermail. Yes, I've installed the Thunderbird pro addon.

What is happening...

Hello, I'm a user who's blind, of course as per the accessability topic I selected here. I need help with thunderbyrd and reaching back to the messages list from either a message body and/or now currently, from the settings pane. I've tried the following: 1. Hitting F6 to figure out where the message list lies within the cycle of panes, but all I get are the search pane and the reading pane main region. 2. Tried hitting tab from the spaces menu when I find the mail as alt 1. 3. Just going back into that tab, the mail, and nothing works. I still end up back in the settings currently but was in a message body before. No matter how I turn off thunderbyrd and reopen it, this is still happening. I use NVDA only for games/current screen reader in use, but I mainly use JAWS for Windows, which is on its latest updates. NVDA is as well. Is there anything you can suggest or should I just use the outlook new from Microsoft, which I still have but it's a pain to use with screen readers. Thanks soo much, Ashleigh P

I apologize for the subject line, but there is no better way to describe the problem....

I've been using Thunderbird for a few months now and it has mostly worked well. Then this afternoon I was reading my mail in the Unified Inbox and I noticed something very odd. I had a number of emails showing in the header list with the same "From" and various subject lines. On the face of it, that wouldn't describe any weird behavior except that I noticed the subject lines absolutely didn't match the "From" information.

As I would go to read these emails, the email itself would be correct in the preview pane -- including showing the correct sender name and email -- but the "From" information in the header list pane would still be wrong.

I'm sorry that I can't post a screenshot to make this more clear because there is just too much personal information on screen. But these emails are from several different senders, received by several different email accounts. Everything is correct except that the "From" shown in the header pane is wrong. This is very obvious to me because I normally run entirely in the Unified Inbox with the emails sorted by the "From" information

One example is an email that is actually from "U.S. Department of Veterans Affairs <do-not-reply@notifications.va.gov>" which Thunderbird displays correctly in the preview pane (where I usually read my emails) and if I open the email itself, but the header pane says this email is From "Prepper-co <joshua@prepper-co.com>"

Another example is an email that is actually from "USPS Customer Support <uspscustomersupport@usps.gov>" but the header pane says it is from "Rainier Arms <sales@rainierarms.com" < p></sales@rainierarms.com">

These two examples were received in different email accounts that aren't even on the same server. I have other emails from these same senders that are shown correctly

I found this problem while using 150.0 (64-bit), which said 150.0.1 was available, so I restarted Thunderbird and it updated to 150.0.1 (64-bit) but the problem is the same.

It's very odd. Normally moving an email, say from the Inbox to the relevant year's archive, takes "no time at all".

Which is true for all the mailboxes shown on the attached screenshot, EXCEPT for the four at the bottom. Moving even one message from Inbox to Yiddish can take ten seconds or longer (with the dreaded "Not Responding" occasionally). Moving something in the opposite direction is also screwy, only from those four.

I had thought that it was because they're rather large. This first started when there were just Yiddish and MSW, and I split off most of the earlier years into the archives shown. To no avail.

It's only an annoyance, but I'm puzzled about how such a thing could happen.

Also very slow tagging or untagging a message just in those mailboxes.

When I try to send a email from my secondary account I get the following error: A unique identity matching the from address was not found. Message will be sent using the current From field and settings Identity. In other words my main account sends a message to my secondary account. When I try to use secondary account I get the error message. The secondary account does not work now.

For the past 30 years I have had an e-mail account with FreeNetName in the UK, which during that time moved to Madasafish and then PlusNet.

I have always run the account on Thunderbird as POP3.

I've just moved the account to GoDaddy and set up an Outlook e-mail account with them.

I'm unable to set up Thunderbird on POP3 or IMAP to be able to access my e-mails, despite having followed numerous articles.

When trying to complete set-up, I get the error: "Configuration could not be verified. If your username and password are correct, it’s likely that the server administrator has disabled the selected configuration for your account. Try selecting another protocol."

Within the Outlook settings, the "Let devices and apps use POP" slider is greyed out.

Has anyone else had this issue?

I have a POP3 account which will not download new emails. The indication is there are no new emails. I can access the email account through gmail and there are many new emails. I have checked password. I have gone through the re-indexing procedure and all other possible solutions I could find. I did find some information about Java and incidentally, there was a Java update on the day my emails began to fail, 8-16-2026. I found this error message, but I don't know how or if I can fix this: module is not a constructor ExtensionCommon.sys.mjs:1679:15

   asyncGetAPI resource://gre/modules/ExtensionCommon.sys.mjs:1679

Thank you for any help you might provide. Please email to [redacted email from community support forum]

A few days ago someone sent me an email with a .png file attached. Normally .png files open in something called Microsoft Photos but I accidentally selected to view it in PhotoPad, rather than in Photos. Now, every time someone sends me a .png attachment, Thunderbird always opens it in PhotoPad.

Is there somewhere where I can correct this so that in future, they'll go back to opening in Photos?
