Hello Team,

Please be aware that we are encountering issues configuring POP for Office 365 using Thunderbird, as it is generating an error stating the username and password are incorrect. Our Multi-factor Authentication (MFA) is enabled, and we are attempting to utilize OAuth2.

Hi All, I've been running TB on my home desktop since ancient times. Present config has been working for quite a long time. TB manages more mail accounts, of which two connect to my remote server (and two others to gmail and freemail). The day before yesterday evening there was a power blackout while I was using TB. Since then I have the following problem:

1. First mail account says: "Could not connect mail server <remote server>; the connection was refused". Now I cannot even see the sub-folders of this account in TB while the folder files themselves exist. 2. Second mail account (to the same mail server, to another mailbox) works partially, it says after sending an email: "Your message was sent but a copy was not placed in your sent folder (Sent) due to network or file access errors."

Connection to mail server is via ssh portforwarding (for TB smtp is localhost:2525, imap is localhost:1143, ssh tunnels work as I can telnet to them and imap/smtp services respond). What is more, from the home desktop my wife (different local desktop user) can normally access her mailbox (different email address on the same mail server) with the same ssh tunnelling method. She was not logged in and was not using TB when the power crashed. After power had come back I ran fsck, filesystem is clean.

So I think that some setting(s) must have gone wrong under my TB profile and it is emphasized more by the fact that in the first case error msg the name of the remote server appears instead of "localhost". Account settings in TB seems to contain the original server settings (e.g. locahost, 2525, normal password, no connection security, etc.)

Only strange thing I could find in Troubleshooting list is that under "Mail and news accounts" it lists account2 (imap) localhost:1143 None Normal password while in the outgoing server column it contains _two_ times the locahost:2525 setting.

In config editor the mail.server.server2.hostname points to the original name of the remote mail server (instead of localhost???).

So what can I do if I wanted to avoid deleting the two mail accounts and re-configure them, especially considering the fact that the mailbox size is about 80 GB.

Any ideas are welcome and appreciated.

Thanks in advance, KEA.

When I download messages, it often says there are say '6 new messages', but only 3 appear on the screen. I'm wondering whether the others are going to Junk, but I am unable to access it. So my question is, how do I access Junk Thanks David White

I am trying to set up a new account so that I can send email through a mailroute server instead of my provider, comcast. I set up the account without a problem but I get an error when trying to send a message. I was never asked for an SMTP password and none is visible in the Saved Password window.

Debugging message filters and want to see the log. From message filters window I click box "Filter Log". It brings up the small config box of which a pic is attached. I can't find anyway to actually see or access the log. It must be hiding here somewhere ? ?

I have tried to clear the log so it is small in case it is large and takes long to load as I've seen elsewhere. No change.

I try to look this the "Activity Manage" which has some log like error messages but it is a mess of unordered seemingly random successes and some failures. This is another topic.

So, any guidance on how to use the filter log would be greatly appreciated.

Hello,

I was using the latest version of Thunderbird 115.11.0. It stinks. It's slow and very buggy. It's the same on all my Windows 10 PCs. I have uninstalled it and went back to V78.13.0 (64-bit). It is MUCH better. And it retains features that were annoyingly removed in later versions.

Why do you keep "improving" Thunderbird when the older versions were perfectly good? Is this because you needed it to look "modern"? That's BS because it will look outdated by next year anyway.

Why did you change the configuration files? I had to re-enter my accounts and address book.

Are these "improvements" because you needed it to look "modern"? That's BS because it will look outdated by next year anyway.

Thunderbird is awesome two years ago. Now it's basically useless.

I have found several on the internet, but none of them work.

At this point I am beginning to get desperate.

Thank you to one and all for assisting me. Ask me if you have any questions or info you need.

I am configured as follows for outgoing messages for Comcast: Details of selected server: Description: Comcast Server Name: smtp.comcast.net Port: 465 User Name: ellary@comcast.net Authentication method: No authentication Connection Security: SSL/TLS

This was the setting recommended by Tbird. Incoming messages are fine. What is wrong.

Login to account “xxxxxxxx@sbcglobal.net” failed ? Login to server inbound.att.net with username xxxxxxxx@sbcglobal.net failed. Retry Enter New Password Cancel then I get this: "Error with account sonomabridge@sbcglobal.net Sending of password for user xxxxxxx@sbcglobal.net did not suceed. Mail server inbound.att.net responded: [SYS/TEMP] Server error - Please try again later.

I was running MacOS Catalina 10.5.6 and upgraded to Sonoma 14.5. I know it was stupid to wait so long, but that's where I am.

After many years of using Thunderbird, I stopped using Thunderbird for my email years ago because my old provider gave up the ghost, and I switched to gmail even though I loved Thunderbird. I still had many documents in Thunderbird which I didn't transfer to other applications or locations.

Today, I finally gave up and did a massive update on my MacOS. Now Thunderbird won't run, and I desperately need many of the documents that I could only access through Thunderbird. When I went to the site for updating Thunderbird, the first thing I needed to know was what version I had, and the instructions assume you can access that info as you are running Thunderbird, which I can't do now. Please help!

Thank you, Sara

Still sorry for asking K-9 Mail questions on this forum. Can't find anywhere else. Every day, get an email on my phone that says: Failed to send some messages IllegalArgumentException: boundary can't be null

Does anyone know what it means and how I can fix it? If you know any specific site for K-9 Mail, please let me know.

dzień dobry, od jakiegoś czasu na jednym z moich adresów po kliku dniach znika poczta, kasowana jest też z serwera, jaka może być tego przyczyna? podstawowe ustawienia są takie same dziękuję za pomoc

I permanently deleted all messages in a folder (call it "Unwanted"), then moved Unwanted to Trash, then deleted it permanently. It appeared to be gone. However the next time I opened Thunderbird, Unwanted was back. I tried this several times with the same result. I tried renaming it to "DeleteMe" but then I got the message "The folder could not be renamed. Perhaps the folder is being reparsed, or the new name is not a valid folder name."

Once again, I "permanently" deleted Unwanted and closed Thunderbird. Using a file manager, I found and deleted all relevant folders and files matching "Trash.*" and "Unwanted*.*" and rebooted the computer. However when I opened Thunderbird, an empty "Trash" folder was regenerated as expected, but the "Unwanted" folder was back.

How can I get rid of Unwanted? Thanks!

Hello,

I am trying to sign in to my Yahoo email account in Thunderbird. I enter my email address, and my password (double checking it's correct), then I click Continue, then it finds a POP3 configuration for my email address. Then I click Done, and it stays stuck on "Checking Password", until ultimately it tells me "Unable to log in at server. Probably wrong configuration, username, or password."

Aside from this, I would like to store all my emails on the server (using IMAP?) and not on my computer using POP3. So when I go to configure IMAP manually and try to type in the values on this page ( https://help.yahoo.com/kb/SLN4075.html ) (although the fields don't exactly match), I type everything in and the "Done" button is greyed out so I can't even continue.

I found one other topic but they got farther than I did and they got to the Yahoo sign in screen which I did not, and they are using OAuth2 which I don't think I am, but I'm not sure.

Does anyone know how I can fix this and set up my Yahoo account with Thunderbird?

Thank you,

Michael Murrin

Got a new computer. Loaded Thunderbird and set up. Received a few emails. Then realized need to move Profile from old computer. Forwarded the few emails I got to another rarely used email account. Thought uninstalled (?) Thunderbird from new computer. Transferred Profile and ini to new computer. Thunderbird started on its own (?) but with about a month older version of my local files, and older emails. Mozilla Thunderbird did not appear in Windows start directory. Loaded Thunderbird again on new computer, and got back in the Windows start directory. Eventually got all my old emails were sent to me automatically in the (correct) Inbox, and I retrieved the few emails I forwarded to my other rarely used email account. Long story short, I got everything straightened out, but with one big exception. A second Inbox, the one that now receives my email, is now in my Drafts folder. How do I get my correct Inbox to receive my mail instead of the second Inbox in the Drafts folder? Thank you in advance to whomever has the expertise to straighten this out.

I use a Google Workspace account in Thunderbird. I have six main folders and each has sub-folders. I create search folders for each and favorite them so they’re across the top in TB. The individual emails then show up in each and I can chose to only show the unread ones. As far as I know TB is the only email program to allow this and it’s great. Recently I’ll be working away, pleased that I’m not getting inundated with emails, only to find out that I’m missing bunches of emails because the folders aren’t updating. I can open the individual folders and they’ll download new emails, which will then populate the search folders, but not getting to emails in a timely fashion is a problem. Anyone know what’s going on? TIA.

Dzień Dobry Chciałbym poprosić o pomoc w poniższej sprawie: Posiadam Macbook Pro i zainstalowałem Thunderbirda. Niestety przy każdorazowym uruchomieniu programu wiesza się on na 1-2 minuty. Podczas tego zawieszenia u dołu ekranu Thunderbird jest napis: "Nawiązano połączenie z serwerem, wysyłanie identyfikatora użytkownika". Czy jest możliwość wyeliminowania tego problemu? Z poważaniem Krzysztof Stoltmann
