Thunderbird Community Forum

Hello,

All my outgoing messages are bouncing back to me, no matter who I send or reply to, just from one of my email addresses: heidi@benvenutotravel.com

So I cannot reply to anyone nor send, although it shows copies in my sent folder???

I have reviewed the previous forums on what changes to make to the outgoing stmp for outlook and have implemented them however, I am still unable to send emails. Please see attached for the edit smtp settings I am using. According to the forums these are the correct settings. The only difference is that I don't seem to have the ability to set authentication method to login as that is not an option for me.

What am I missing?

On Linux, closing Thunderbird also closes Firefox if Firefox was initially opened via clicking a link in Thunderbird. I don't know if this would qualify as a bug, but is there a way to have the Firefox process start independent of Thunderbird when, for example, clicking a link in an email? I'm running 115.12.0 (64-bit) at the moment, but it happens on previous versions as well.

For some reason now, every time I go to type a response to an e-mail, the program loads hundreds of lines of text below my earlier sent message. Need help as to how to fix this problem ?

Received an encrypted message but the content appears to be only my public key. Message not visible. Copy of same message was displayed in the clear in gmail on a computer that not set up to encrypt. Any suggestions gratefully received.

Hi, I am trying to login to my emails and after entering my password the following message comes up message comes up. 'Login to server mail.optusnet.com.au with username dianne.hill failed' Can you please help me?

Thunderbird has for the past few days begun giving me this error message every time I lick into your program. "Login to server imap.gmail.com with username rg.mccormick43@gmail.com failed". I am also recieving this message for aol.com.

Interestingly, gmail messages continue to come into the program but I cannot send any messages. Unless this is fixed quickly I will drop your program and go back to using google, which I hate, for my email program.

I have 2 windows 10 computers both with Thunderbird. One computer never has trouble with getting emails. The other shows every day "Login to server mail.hoster905.com with username cnc@lcgnm.com failed" I have reset this one password at the server, entered the new password in Thunderbird and can the get mail. That day only. Next day same problem.

For the last 2 or 3 days I have been receiving the above message when accessing emails. I have experienced this problem occasionally in the past and for a day at most, the problem usually associated with virginmedia. However this is now proving to be disruptive and I don't where the problem lies, with Thunderbird or Virgin. None of my settings etc. have been changed and I can access everything if I go directly to the virginmedia website but the handling of the emails is cumbersome. Any ideas?

It seems as the interface thinks the window containing Thunderbird is longer than it actually is. The bottom part of the interface is missing and there's no scroll bar. This is most apparent to me in the Address book, where part of the fields is invisible, as are the Cancel/Save buttons. When I start Thunderbird, that bottom part of the interface would appear for about a second and then disappear. Resizing the window doesn't help.

When I start Thunderbird in Troubleshooting mode, the interface works fine, but "Reset toolbars and controls" and "Disable all add-ons" doesn't fixt the issue.

It might have started when I connected a secondary monitor, positioned above the primary. I thought disconnecting that monitor fixed it, but I since reconnected it and the issue now won't go away except when in Troubleshoot Mode.

using 115.10.1 for emails... each day there are plenty so i pile them up into one place until the folder reaches a size or a date and then we start over. yesterday, the pc updated and almost immediately the search was gone. i would type abc on the search bar and it would take for ever to scan through the messages. then i would click on the email i wanted but something else would open up in the message pane... https://support.microsoft.com/en-us/topic/may-14-2024-kb5037768-os-builds-19044-4412-and-19045-4412-cb676101-1641-4a6c-b512-8b277606c6e3 https://support.microsoft.com/en-us/topic/kb5034441-windows-recovery-environment-update-for-windows-10-version-21h2-and-22h2-january-9-2024-62c04204-aaa5-4fee-a02a-2fdea17075a8

today, i guess, it crashed completely . it started by firing of a warning that not enough space is provided which was not true, then it downloaded 10 messages at once... after a while, the message pane was lost. you click on an email and nothing. it selects it but nothing shows up. blank screen. double click, also opens a new blank tab. fearing a totally corrupt database or even a re-install i pressed repair on the folder. took ages. now, though, i have the profile folder in my PC intact, but TB refuses to load it. i only see the 20 emails i got lately. like starting a new profile all over again...

I ran into an error on my Windows 11 PC. If I add an attachment via the system menu called up by the right mouse button, the size of the attachment is displayed in terabits and cannot be sent :-)

Hi. I have used Thunderbird for a long time. I have never had a problem accessing my hotmail account for emails. Overnight Thunderbird now posts error message boxes when trying to login to the hotmail server. It reports incorrect username or password. Neither has been changed by me and comparison with Eset Password Manager shows them to be correct. I can login to Outlook online using the same login credentials an get my emails that way. I have also changed my Outlook hotmail password while logged in in my browser and updated everything on the PC to match of course.

I have massaged the server Settings for hotmail and have had the system working again, for a while. Twice I have reset the settings to a different server and back again and that seems to clear the problem for a while. Then the error messages switch on again consistently. At this moment using "File" -> "Get New Messages For:" -> "Hotmail" works without any problem and the automatic scheduled checking reports "No messages to download" so it appears to be working. But that is after just coming back to my PC to find a string of failed attempts, each with its own error box, which have appeared since I last "fixed" the problem and assumed it was now fine.

My server settings are Type: POP; Name: pop-mail.outlook.com; Port: 995; Username: same as for browser access (which works); Password: As in Thunderbird's stored passwords matching Password Manager and working browser access.

In my paranoia I have even wondered if I am being locked out by Microsoft somehow. Can anyone suggest what is going on here?

1 of my customers are experiencing ThunderBird not responding, very random when it does not respond, Windows 10 Pro 64 Bit I checked that Mozilla ThunderBird is running latest version (x64 en-US) Version 102.3.3 The fixes I have tried are running the setup exe file I have checked email settings are correct Check task manager to see if anything is overloaded such as RAM Memory Check AVG Firewall and allowed ThunderBird Adjusted Windows power management settings to high power plan

Recently (~January 25, 2023) in Thunderbird (102.7.0) my outlook.com email (SMTP) stopped working with the error message, "Login to server outlook.office365.com with username xxxxxxxxxx failed."

• I see some have suggested changing Authentication method to "OAuth" from "Normal Password" but this has not helped. (Not sure if OAuth is different than OAuth2, but only OAuth2 is an option in Thunderbird)
• I have tried setting the Authentication to OAuth2 in the outlook.com account => account settings => Edit SMTP server
• I have tried setting the Authentication to OAuth2 in the outlook.com account => Server Settings
• In the outlook.com account => Server Settings - Connection security is set to SSL/TLS; Port is 993
• In the outlook.com account => account settings => Edit SMTP server Connection security is set to SSL/TLS; Port is 465

For months I was experiencing the problem of "Thunderbird not responding" occasionally. It was a short duration issue (a few seconds to a minute). I reinstalled Thunderbird several times without success. I read almost every comment available online about this problem and I tried many ideas and recommendations I found without success. Most recently the problem became so serious that it was not a nuisance any longer. It was nearly impossble to work waiting for minutes to open an email or to continue typing while preparing a message and being interrupted by the problem I am describing. I ran Thunderbird in safe mode and determined that none of the add-ons is causing the problem. I turned the firewall OFF and determined that firewall was not causing the problem. I then decided to run Thunderbird in Offline mode and found that the program works normally. Then while in Offline mode I decided to download more messages and the program asked me if I wanted to switch to the Online mode. I said yes. New emails were downloaded and without going back to the Offline mode I was able to work normally without any occurrence of the "Thunderbird not responding" problem. I have been using this workaround for several days now. I download a number of eamails. I try working in Online mode and I cannot do it. I switch to Offline and work fine. I switch back to Online mode and I don't see the problem any longer for the whole day. Do you have any idea as to the origin of my proble? I am running Thunderbird 115.10.2 64 bit on Windows 11. I had the problem originally using Lenovo T490s and more recenlt Lenovo X1 Yoga

Thunderbird 102.15.1 had been working perfectly for years until today. Popup message "login to server imap-mail.outlook.com with username XXXXXX@hotmail.com failed". Hit Retry, no good, selected "Enter New Password" and entered the original password but that also failed with same message. Login to Outlook on web with original password still works. I don't want to change the password, as it is also for my Microsoft Account. Settings follow: Server Type: IMAP Mail Server Server Name: imap-mail.outlook.com, Port 993 Outgoing Server (SMTP): Microsoft Live Hotmail - smtp-mail.outlook.com The other email account, xxxxx@charter.net works properly I have been monitoring problem reports and dissatisfaction with formatting on new version 115, and do not want to upgrade from 102.15.1 until users seem happier with 115. Please advise how to get Thunderbird to accept/use my Hotmail password.

I just noticed that if I check the SENT folder, some of the emails I sent have this text in the body part.

"This is a multi-part message in MIME format.

Content-Type: text/plain; charset=UTF-8; format=flowed Content-Transfer-Encoding: 8bit

[HERE THE CONTENT OF THE EMAIL I SENT]"

I'm wondering if they are sent like that, what the receiver will see and if there is a way to prevent it.

The email account is using IMAP and as far as I know it happen just to that specific email account. The emails are sent using Thunderbird. I'm using the latest version of Windows on a laptop. I'm using the following Thunderbird extensions (latest versions): - Compact Headers - Send Later - Mailmindr - Quicktext

Thanks.

When Thunderbird updated to 102.6.1 the other day, my address book disappeared. No more personal address book or contact lists. Gone. (My 'Personal Address Book" went from 2,000 names to 24. Yikes!)

Plus, I can't even type people's names into the emails and expect it to populate like before. I have to search for their emails and rewrite it.

Is there a way to fix this? Or to roll the program back to the previous version?

Since I backed my email list up last month, I've made lots of changes. But if I have to, I'll just re-import and try to recreate what I've done. (Reminder to self to back up more often).

Thanks for any help or guidance. PS - I'm on Windows 10.
