Thunderbird: форум сообщества

As of today, Thunderbird will not make contact with my servers and won't download emails. i had been having some issues with Thunderbird not sending emails last week. Plus, Firefox won't connect with my internet provider's website so I cannot access emails thru webmail. Firefox either times out or says connection could not be made. Could there be an issue within account settings?

Why is Thunderbird consatntly coming up with "Authentification failure while trying to connect to server outlook.office365.com"? It never used to and would download my hotmail emails perfectly until about a month ago. This is very frustrating, I have removed my hotmail account from thunderbird and re installed it, works for ocassionally the back to same old message authentification failure. What is going on with thunderbird?153.02

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 receive the following error message: Not enough disk space to download new messages. Try deleting old mail, emptying the Trash, and compacting your mail folders and then try again.

I get the message when I want to download new emails. The suggestions to fix the problem DO NOT WORK. I cannot compact, the Trash is empty and I know there is GB's of space on my C: drive, which contains all Windows software. What to do?

family and friends, communities sending info directions to my Inbox and I'm not receiving these emails. We always compare if I gave them the right email address. I need help to correct the problem.

Desktop Thunderbird no longer downloads mail from Yahoo though it did until 2 weeks ago or so. Now when checking for mail, I only see a "Local Folders: Checking Inbox for new messages" (screenshot) that eventually disappears after a while with no download. I can still send messages out from Thunderbird through Yahoo. I have done the "Please check the following before asking for support" : 1. I can log into my Yahoo account via the web and am using the same password 2. I only have one Yahoo account; all the other accounts work fine 3. I can send mail from Thunderbird through my Yahoo account with no problem 4. OAuth2 is active and can successfully establish a secure connection (screenshot) 5. Cookies are enabled with no exceptions (screen shot) 6. I do not use a VPN 7. Version is 151.0 (screenshot) 8. I checked the Error Console messages when Checking Inbox was active (screenshot) but do not understand it

I blocked out information on non-Yahoo accounts and email subjects on screen shots

After updating to 153.0.1esr(aarch64). the SEND button has disappeared. There's no way to send an email. (I can receive emails.) I am a Mac mini M2 Pro. OS 26.4.1

I cannot find a link to download a previous release of Thuderbird, which was working fine until this update.

I got a message: "Authentication failure while connecting to server outlook.office.com." Please assist in getting this resolved.

Thanks

A "send later" button came up one morning instead of the usual "send" button. When I clicked on the write button to see where the "send" button was, several choices came up but when I clicked on the "write" choice I lost the other choices and now can't get back to the original write button and still no "send" button appears anywhere on the menu. I can save messages to Draft but still can't actually send them. I can still receive emails, just can't send them! Help!

Thunderbird stopped downloading gmail this morning. It worked fine yesterday. I've restarted it 3 times to no avail. It says "Connected to imap.googlemailcom..." and it's been saying that for 2 1/2 hours now. Please help.

And please respond in non-tech terms. I am an old lady and I don't understand any of the stuff in the "help" section of your website. Still running Win10 because I can't handle the learning curve to 11. Please and thank you.

Login to server smtp-mail.outlook.com with username XXXXXX@outlook.com failed.

I am having this error I have tried logging back in, can download mail but not send any. Any ideas? Thank you

I have three separate Yahoo email accounts. I set up Thunderbird to link to each Yahoo email account separately. It worked fine for a year or more. On 5/25/26 one of the three Thunderbird email accounts stopped downloading emails from Yahoo. I could see at the bottom bar Thunderbird indicating that is was downloading 1 of XX emails, but never actually downloads them. There is no error message. I checked the Yahoo email account to verify the number of emails I am missing from Thunderbird and the number is correct. I can see the emails in Yahoo. I'm the only person using Thunderbird, so no changes have been made to previous settings for retrieval. I confirmed Security and server settings for Thunderbird in and out going emails, and Yahoo are correct. I tested the connection in Thunderbird, and the connection is successful. I tried to send an email from the Thunderbird account having issues, and the email was sent and received by the recipient. The recipient replied, and Yahoo received the email, but failed to download it to Thunderbird...along with all the other emails since 5/25/26. I unlinked the account and reestablished the link between Yahoo and Thunderbird, and still not fixed. I tried restarting the computer, with no change. I tried to send an email from Thunderbird to one of the other Thunderbird emails and it was sent and received. I made changes to Thunderbird to force the download of emails, and it still wouldn't do it. I turned off my antivirus, closed Thunderbird, and restarted it, and that didn't change anything. The capacity of emails on the email in question only has 739 emails, so it's not over the limit and I have plenty of storage capacity. Thunderbird is set to save emails, Cookies and cache were cleared, no change. I ran the folder repair feature in Thunderbird, but there was no change. I compared all the settings between the other Thunderbird emails that are working against the one that isn't, and they are all the same. There was a suggestion to close out of Thunderbird and delete the "Global-message-db.sqite" file from the Thunderbird profile in case it was corrupted, and it would recreate this file when Thunderbird was restarted. The file was recreated, but it didn't fix the problem. There was mention that a suspicious email in Yahoo might be blocked by Thunderbird, so I placed various emails in the spam folder, and it didn't work. I did find one email in the Yahoo spam folder that was dated before 5/25/26 and moved it to the Yahoo inbox. Lo and behold, that one email downloaded to Thunderbird. So there is something within Thunderbird preventing emails from downloading after 5/25/26. I've read many people complain about similar download failures with no solid fix. Someone mentioned it fixed itself on a day, but then stopped again days later. Someone else mentioned Yahoo changed its password protocol to transfer emails, but that doesn't make sense since the other two are still downloading based on the "old" password protocol. I'm at wits' end. Thanks for reading all of this. I hope someone has a solution.
