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.

Hi, I am running Nebula 128.3.0esr and I am unable to send from hotmail. When I go into the outgoing server settings I do not have an option for OATH2 which it requires the other settings are all as per microsofts instructions: SMTP server name: smtp-mail.outlook.com SMTP port: 587 SMTP encryption: STARTTLS I suspect I am doing something stupid but all my other mailboxes are working fine.

I use Thunderbird Mail, I have two email accounts, a gmail and an icloud. Now a problem has occurred, all subfolders for icloud have disappeared from Thunderbird. I had different folders of saved correspondence, but now I just see Inbox, Archive and thrash. Anyone know what I can do to get those folders back, for gmail account everything is ok

I have received several emails on my laptop Tunderbird account with content like this:

I can read these emails using BlueMail on my phone. Can you assist in resolving this issue please? Thank you

I have Thunderbird 102.15.1. I can receive emails from my Hotmail account (set up as POP3), and up until 22/09/2024 I could also send emails through Hotmail.

At some point after 22/09/2024 I am no longer able to send emails through Hotmail.

I have the following setting for the outgoing server (SMTP) (which worked fine until 22/09/2024):

Description: hotmail server name: smtp.office365.com Port: 587 Connection security: STARTTLS Authentication method: Normal password

When I try to send an email I get the following message:

 "Enter your password for adriharp@hotmail.com on smtp.office365.com:"

with the password dialog box underneath.

If I change the authentication method to OAUTH2 for the outgoing SMTP server, I very briefly see the "enter credentials" screen flash up, then the Sending message box appears and Thunderbird hangs until I hit the Cancel button. If I leave it to run, I get this message:

 "Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) smtp.office365.com timed out. Try again."

If I try to generate a new app password in my Microsoft account and enter this with the outgoing SMTP server authentication set to Normal Password, I get this message:

 "Login to server smtp.office365.com with username adriharp@hotmail.com failed."

I use OAUTH2 authentication for the incoming Hotmail server (SSL/TLS on outlook.office365.com). This works fine.

My questions are: - does anyone know why this change happened in the last few weeks ? - how can I change my settings in Thunderbird (and/or Microsoft Hotmail a/c) to send emails via my Hotmail account ? - do I need to upgrade Thunderbird to send emails via my Hotmail account ?

I am running Windows 7 on this laptop so I think my options to upgrade are limited to 115.10.01.

Thanks for your help.

I have installed T'bird in a new replacement pc and also added my two accounts. However, I now need to include my many Local Folders using Profile Folder information from the old pc.

Should I delete all the account information I have installed in my new pc T'bird prior to installing the Profile Folder copy? Thanks Ron

Once in a while I would like to email a company with a question or comment and I go to their website, click on an email link and thunderbird email pops up an it is useless. I use Gmail and literally half of the business world is out of reach do to the use of thunderbird. I do not want to use thunderbird I have to many "apps" to deal with already. Still it would be nice to be able to contact people at their chosen email.

What is the fix?

I just reviewed the annual report and I'm all smiles. Great Job!

One thing I noted in the report is the cost of Donation Processing Fees. I'm Canadian and always use Paypal for my donations, but wonder if it would be of more benefit to you if I used an alternative.

Is there another service or credit card that would be a lower cost to you?

please see attached msg. annoying distracting symbols by default inside search screen. why? I know command-K bring up some somehow useless search screen but the rest... annoying - it attracts attention as a new item and clutters the view and serves no purpose it's control command K

I'm on version 128.2.2esr on MacOS (M1 Macbook Air) and an email that I've sent today appers wrong in the "sent" folder as show in the attached screenshot.

The email is shown in the sent folder properly in other clients (Apple Mail on iOS/iPhone) and webmail from email.cz which is my email provider. One of the recipients of the email confirmed, that he's received the mail correctly.

Thank you!

Using Tbird 78.14.0 (64 bit) with Windows 10. I can no longer access the Page Setup screen properly. I suspect it's because I accidentally put a very big value in for the top margin. The print preview for even a short email says it's many pages, there's no text visible on any of those pages, the only part of the Page Setup screen visible is OK and Cancel at the bottom, and I can't get to the top of the screen. I've tried closing and re-opening Tbird to no avail. How can I get to the top of the Page Setup screen to fix the problem?

Hello,

I recently reinstalled Windows on my PC and had to upgrade Thunderbird to 128.3.0esr. Now, when I open an event from the Calendar, it opens in a tiny window with an Edit button. When I click on the Edit button, it opens the event in a slightly larger window that has to be manually resized in order to properly edit the description and other details. There is no standard "Maximize" icon on this Event window. In older versions, the Event simply opened as a new tab in the main UI, which was vastly more efficient and user friendly. Is there any way to reenable this functionality? The current functionality is a bit frustrating.

Thank you.

Hello, VER: 128.3.0esr (64-bit)

Since I have updated to the newest version of TB, it is now a continiuous issue with "Not Responding". This is happening on three different computers with my mail accounts. I am using Godaddy (IMAP) as my mail service, and they now use Office 365. I did read in a post to add my profile to my firewall exlusion. This did seem to solve my issue, but I have since removed it as I am not sure it is safe. Is there any safety issue adding the profile to the firewall exclude.

Thank you, JR

I have Thunderbird 128.2.3 (32 bit). I have set Server type IMAP mail server, then Server Name to: outlook.office365.com and Outgoing Server: smtp.office365.com I have OAuth2 on both. When I enter, I get a new Thunderbird input that requires a password. My password does not work, the therefore my email account does not work.

I have confirmed that my Outlook Password is correct. I have cancelled my Outlook passwords. I have installed the 2 step verification option.

What needs to be done so I can use Thunderbird on my PC Win 10? Thank you, Ed

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!

I have been using thunderbird for years and have 2 lightning calendars. These are stored locally in home/.thunderbird on Ubuntu - currently 24.01.1LTS, TB version just updated to 128.3.0esr. About a week ago I stopped being able to save calendar events, getting the message

An error occurred when writing to the calendar Home! Please see below for more information. Error code: MODIFICATION_FAILED. Description: Failed to write to calendar file file:///home/alasdair/.thunderbird/Home.ics: Could not create unique file in `/home/alasdair/.thunderbird' (NS_ERROR_FILE_ACCESS_DENIED)

I have uninstalled and reinstalled thunderbird to no effect. As I am the only user of the machine all prcesses run as me, the .thunderbird directory is owned by me and I have all permissions on it, as I have for all files in the directory. I can create and edit files there no problem. I have no idea how to d=fix this.

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

Hi dear Mozilla-Community,

I have run into the issue that is described here: https://www.reddit.com/r/Thunderbird/comments/1fdwv49/what_is_thunderbird_doing_to_fix_this_outlook_in/ and solved here: https://support.mozilla.org/en-US/kb/microsoft-oauth-authentication-and-thunderbird-202

Now, the issue for me is that i cannot select the OAuth2-password option on my outgoing server option because it simply is not there (see screenshot attached - it's in German but you will get the idea). Ingoing has been changed (automatically, I suppose) to OAuth2 and works just fine but the outgoing is broken.

I am on the newest Nebula 128...esr.

What can I do? Thanks a lot in advance!

Best regards, Konrad

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.
