Thunderbird Community Forum

Starting on 10/01/2024 Thunderbird no longer allows me to send or receive email.

When I try to read messages using Thunderbird, I get the following: Sending of password for user XX@msn.com did not succeed. Mail server outlook.office365.com responded: Logon failure: unknown user name or bad password.

When I try to send messages using Thunderbird, I get the following: Enter your password for XX on smtp.office365.com:

I have tried redoing the password and it does not help.

This is on a WIN/10 system. I updated to the latest version of Thunderbird and it did not help.

I checked out Thunderbird on my WIN/XP and get the same results as with WIN/10.

When I use Firefox and login to https://outlook.live.com/mail/0/, I can send and receive email as before. The same is also true with my Mobile Phone.

I have several POP Mail Server accounts from which I download emails to Thunderbird, including two accounts with Gmail and two with Zoho. I have them configured the same way on both a desktop and a laptop computer.

Up until Sept. 26 all were working fine. After that date, however, I've been unable to download mail from Zoho on either computer, even though I still can download from Gmail. Strangely, I get an error message when I try to download using the desktop computer, but don't get one with the laptop. In neither case, though, will the Zoho email download. The error message, titled "Error with account Zoho_cof", says:

"Unable to write the email to the mailbox. Make sure the file system allows you write privileges, and you have enough disk space to copy the mailbox."

I have plenty of disk space on both computers and have not changed write privileges.

Since the problem is restricted to Zoho and occurred simultaneously on both computers, I thought the problem lay with Zoho. They, however, claim that the problem lies with Thunderbird.

I've attached screenshots of the configuration page for one Zoho account (which stopped working) and for comparison one Gmail account (which continues to work).

I've run Thunderbird in Troubleshoot mode and still get the problem. Can anyone offer a suggestion as to what to do? Thanks!

When I select multiple Inbox messages and right-click, there is no choice shown to delete all of them. Please see the uploaded images.

Thanks for your help, SweetTasha

This is what most of my received e-mail messages now look like:

<td align=3D"left" bgcolor=3D"#ED3B30">

Some e-mails can still be read but the message is from a previously deleted e-mail and is not what the current e-mail is about. (A message from a previous e-mail has been inserted into the body of the new e-mail and the info. in the new e-mail has vanished.)

Can someone help me? Thank you.

I tried to update my email password and when Thunderbird prompted me for the new password, I entered it but now I get a message stating that Thunderbird could not connect to the server. I have looked at several other posts describing a similar problem but so far have been unable to solve my issue.

My Thunderbird goes through periods where it can receive but not send emails. I am presented with the following message, see attachment. The number may vary but the message is always the same, I am being blacklisted. Can anyone tell me way this is happening, and what to do to fix it, Please? As far as I can remember, it sorts it self out, but it hasn't for over a week now and it is really frustrating. Thank you for reading this plea. Regards Ilio Pieroni

Forum says you need a screenshot to help diagnose but Thunderbird doesn't allow screenshot of settings... So, Server Settings:

 Server Type:  IMAP Mail Server
 Server Name: imap-mail.outlook.com  Port: 993

Security Settings

 Connection security:  SSL/TLS
 Authentication method:  Normal Password

Running Thunderbird 115.10.1 (32 bit) Outgoing Server (SMTP) Settings Microsoft Live Hotmail - smtp-mail.outlook.com (Default) Windows 11 Home V 23H2

I've tried everything I can think of and read/tried lots of suggestions including turning off firewall, password changes, etc. I don't recall any updates or changes to anything when the problem started several days ago. Exasperated. Thanks for any help.

(PS - I do, on occasion, send a few $ to Mozilla. ;-) Thanks for your time.

Hi there

I created a new folder in Thunderbird. It asked me where I want to put the folder. I accidentally chose my email address folder instead of the local folder. Now under inbox I have drafts, sent, archives, spambucket and the new folder. I tried to delete the folder. I get the message " are you sure you want to delete the folder. "I click on delete folder. Nothing happens.

Over the past couple of years, I will receive one or two emails that displays as a scrambled mess of characters, and sometimes one email is combined with another (the header of one mixed with the body of another). However, this morning, I received several scrambled, combined emails that I can only read if I log into my email provider/hosting company. What is going on and what can I do to stop this? I have no technical skills for going in and coding anything.

I am using Thunderbird 115.15.0 (64-bit) on openSUSE Thundebird. This is the KDE version. I have verified that it fails with both the Wayland and X11 versions.

Why I try to print an email, the Print Dialog appears with the circular animation and the message "Preparing Preview." It then hangs in a loop. The only way to stop it is to use the System Monitor to Kill Thunderbird.

This is a serious problem as there are emails that need to be printed and there is no convenient way to print them otherwise.

I have quite a few email accounts coming into Thunderbird. I'm about to add another but want it to be the third account down, instead of 8th. How do I move whole accounts up or down the list?

Just a couple days ago I started having issues with some emails from trusted senders that I never had before. When I open the emails, I get this message that I took a picture of. It's related to Apple messages & someone's iphone. I don't own an iphone & have no clue why this started happening recently. Like I said, it doesn't happen to all my emails, just certain ones. Looking at my picture posted, does anyone have an idea what's going on with this?

Best Buy installed a new hard drive with additional storage capacity on my computer. A lot of stuff got wiped out and had to be re-installed, including Thunderbird. Now, Thunderbird is slow to respond to the server and even simple reply messages can take a minute or longer to send. It takes a long time to get messages, send, etc. What can I do to increase speed? My ISP tells me I have 45 MB of speed [soon to be 300mb] and that something is slowing down the email process, not them. Also, when I forward a message Thunderbird sends all the coded info with the messages that confuses the receipient. For example, if I send a political cartoon, some will delete the message because the cartoon is on the very bottom of the message and all the sending material is first and he thinks the message is a gag of some sort. Messages used to just show the sender and receipient(s) names and topic, not all the unnecessary detail involved in the message itself.

Can you please me with these issues, as I am so frustrated that I am exploring using Gmail or Outlook instead.

Thanks. Jim Maciej jvm1@windstream.net

I know how to add a new contact to address list so don't need that again - that is the advice I'm given every time I try and find an answer on line - from your web site also. My problem is, that after entering new contact name and other details, the entry box for the email address(bottom of the list) is hidden (or the panel which holds those details is too narrow to allow for the email entry box to show.??). With the occasional problems I have, and the time spent sorting them out, I'm starting to think of installing another mail program. I will appreciate any advice you can give. Thanks and Kind Regards, Colin Churchill

Hello,

Even though [replied in another similar thread] that I have the same issue, I'm making another one 'cause it seems pretty dead.

Since ver 128 Nebula, some mails (sorted in a labeled folder) appear totally white / blank and I don't know why. They appear perfectly fine when viewed from my provider's webmail service (Gandi SOGo), but not in Thunderbird. But here's the thing: they appear fine from the sent folder after I replied to them (via the webmail).

I've already tried restarting in safe mode with all modules disabled, to no success.

Hello,

In Thunderbird I created many filters too get my incoming mails organized. The majority of my incoming mails are re-directed to sub-maps within 'Local Folders.

I sometimes want to know to which map I re-directed incoming mails, and open the related filter definition. As path indication I unfortunately I can only find the word 'Local Folders' (which is right), but not the full path to which messages are re-directed. Can somebody please provide me a solution, thanks?

I have an email account ...@outlook.de. I haven't been able to send emails for a few days. Email reception works. SMTP-Server: smtp.office365.com Port: 587 STARTTLS OAuth2 Errormessage: Failed to send message. The message could not be sent because the connection to the SMTP server smtp-mail.outlook.com failed. The server is either unavailable or refusing SMTP connections. Please check the SMTP server settings and try again.

I attached a file which TB correctly showed to be 23.3MB in size. (FileLink's not an option.) But when I clicked on Send, it asked me if I'm sure I want to send an attachment of file size 31.9MB! The initial size would have gone through. Gmail would not accept the latter size. How did the size grow by nearly 8MB?!

My Thunderbird version is 128.2.3esr (64-bit) running on Windows 10.

My Thunderbird shows the following folder tree Local Folders / MailStore Export / Outlook gmail / Organizations / _Service Providers / Health Providers / Cleveland Clinic (Sports Medicine Specialists) - Shelagh Baker - Mailstore says the folder contains 913 email messages - the folder shows as empty in Thunderbird

Windows Explorer has the following folder tree: C:\Users\Sam\AppData\Roaming\Thunderbird\Profiles\ardwce2w.default-esr\Mail\Local Folders\MailStore Export.sbd\Outlook gmail.sbd\Organizations.sbd\_Service Providers.sbd\Health Providers.sbd - this folder includes a 38 files that seems to represent the 19 email folders in the Health providers Thunderbird directory (two files per folder) - the two files representing the email folder "Cleveland Clinic (Sports Medicine Specialists) - Shelagh Baker" are "Cleveland Clinic (Sports Medicine Specialists) - Shelagh Baker" and "Cleveland Clinic (Sports Medicine Specialists) - Shelagh Baker.msf" - The Windows Explorer size of the first file (with no extension) is 213,019 KB; when I open this file, I can see text that matches the content of emails that I see in this same folder in Mailstore

My Conclusions: 1) The email "raw data" exists in the file system 2) For some reason, the Thunderbird client is not "seeing" these emails and thinks there are no emails in this folder.

Other Information: 1) I have stopped and restarted Thunderbird several times, but still no emails 2) At one time Thunderbird showed two folders named "Cleveland Clinic (Sports Medicine Specialists) - Shelagh Baker". Neither of these folders showed any emails. I deleted one of the folders from within Thunderbird. Later I noticed there were also two folders in the corresponding Windows Explorer directory. One was empty, so I deleted it (it is now in Windows Trash folder). The name is "Cleveland Clinic (Sports Medicine Specialists) 0554d8b9"

I'm hoping somebody can provide suggestions on what I can try so that the emails are visible within this folder. Thanks in advance!

Good day, Thank you for your time, its much appreciated So My primary email account provider only permits me to receive but not send emails. Consequently I had to load Gmail in order to send mail. However in spite of all the correct settings gmail also refuses to send. Can you please resque me from this frustration.
