Thunderbird Support Forum

My Thunderbird Version: 115.12.2 (32 Bit)

Microsoft is changing the authentication method for outlook mail to OAuth2. I follow the guide here,

https://support.mozilla.org/en-US/kb/microsoft-oauth-authentication-and-thunderbird-202

And I get to this screen - but my version of the program does not have OAuth2 as an option (see attached image).

Thanks for the help.

Hi,

I repaired my inbox yesterday. I had many messages still in that inbox but after the repair I only see 5 messages. I looked in the directory my profile points to for my email and can see a large Inbox file - but I also see a very small Inbox.msf file. It is almost like the process of rebuilding is pointing to another Inbox file. See the picture attached.

I even tried to take a previous copy of the Inbox.msf file from a backup (it was 800 kb). I deleted the old Inbox.msf file and replaced with the larger 800 kb file. When I opened Thunderbird, it started to something: "Building summary file for inbox" and about a minute later those same 5 emails show - instead of the full Inbox I would have expected.

Is there anyway I can re-associate the Inbox.msf file process rebuild/repair to the correct Inbox file (the one that is 737 meg in this case)? I sure would like to get my inbox messages back (and file them away i/o leaving them there vulnerable to this kind of problem in the future).

Thanks in advance,

Patrick

Hello, i try to customise the thunderbird mail colors, but can't find any settings to that. I want to change the colors for "marked as -> unread" messages and the color for new received messages. Can anyone tell me how to adjust this? I tried to add the "userChrome.css" file in the self created folder "chrome" in my profile directory, but nothing changed. Can someone help me? I use Ubuntu 22.04.4 LTS version and the thunderbird version 115.6.0.

Outlook email accounts are duplicating and asking for passwords which are in the password manager. T/B does not accept the entered password. Gmail accounts are also duplicating and adding weird passwords. Just started last week. Probably has something to do with the new Microsoft Authorizarion rules. It is a mess. I have been a lifetimme used if Mozilla and Thunderbird.

Exported address books and lists from 115.12.1 (32 bit) on W8.1, importing to 115.11.1 (64 bit) on W11.

Importing a named list into personal address book works - but the list itself is lost; they all go into one big address book. If I choose Create a new folder they all go into that - but again I've no list name, I can't write a message to the list like I used to be able to.

I can select New Mailing List, give it a name, but now I seem to have to enter each one individually, I see no way to paste in a list.

What am I doing wrong please?

Tell me how I can continue to use thunderbird with the above account and also Denis.Clarke.hotmail.com after September 18. I have 4 individual historic E mail accounts and thunderbird joins them together. What do you need to do? To deal with threat below.

If you are receiving this email, you are currently using an email or calendar app that uses a less secure authentication method to connect to your Outlook.com email account. You will need to upgrade your third-party mail and calendar app to a version which supports modern authentication methods.

When I start a email message search, I am bombarded with bad suggestions for email addresses. These include addresses from everyone I've received email from even though I have deleted these entries in collected email addresses and my personal address book.

The addresses could be from old purchases or ebay responses or anyone I've ever received an email from. I have deleted most of the emails entirely, yet I still get all these bad addresses when I search.

Is there a way to clear the history in search or remove the email addresses where I have deleted the email?

I've attached a Home Depot search as an example.

I converted my Outlook .pst file to an mbox file using SysTools PST converter When I try to import it into Thunderbird, it permits me to import only a .zip file from a previous backup, or a calendar file, or an address file. I need it to import the whole thing, especially the emails. How?

Hallo, durch eine Unachtsamkeit habe ich das Hauptpasswort (Primäres Passwort.) von Thunderbird gelöscht. Ich finde auf den Hilfeseiten keinen Hinweis wie man da Passwort zurücksetzten kann. Dadurch komme ich nicht mehr an meine Mails. Freundliche Grüße

I have a Windows 10 pc, which is current with all Microsoft and manufacturer (Lenovo) updates. Thunderbird won't run since the last update. It just gives a message saying, "Your computer must be restarted to complete a previous upgrade of Thunderbird. Do you want to reboot now?" After several reboots, I have given up. A support forum solution from 4 years ago recommends deleting a file (global-messages-db.sqlite) at a location (C:\Users\user\AppData\Roaming\Thunderbird\Profiles\8charstring.default) that seems not to exist (hidden?) on my pc. What do you suggest? Thanks.

Hello: t-bird 115.12.2 esr dev build. W11p laptop. Drag & drop (also paste) for putting a file inline for a msg do not function "any more," this has functionned in earlier versions. I can only attach the file. I have changed config ed settings mail.inline_attachments & mail.inline_attachments.text to true & restarted t-bird, to no effect (no inline). This is for a simple .rtf of 340 bytes (yes, very small). Please advise. Thank you.

I can't SEND on Thunderbird as of Update to Version 115.12.1 on 6/19. I was able to SEND on June 18th and left town for a week and when I came back could not Send. That could be a coincidence. Have Windows 11, with Defender Firewall and Security virus protection. I have TB version 115.12.2 up to date. I have checked with Spectrum for the correct configuration and currently I have as Description: SMTP Server (on top line); Server Name: Mail.brighthouse.com and Port 465, No Authentication and SSL/TLS. My User Name: e-mail address ends in @tampabay.rr.com and that is the same as shown on incoming server.

My husband just downloaded TB program on his Windows 8.1 which is my old computer that I've been running TB on for 15 years without a hitch!! ''''And he also cannot SEND.'''' It's very frustrating - we've tried changing server settings since Spectrum uses not only Brighthouse (which is the one they say covers the Tampabay.rr.com address) but they also use Mobil.charter.net and also TWC.com. I've tried changing them up but nothing works. I've tried changing Ports and anything I could change I did, but nothing works. I did get a couple of error msgs but they didn't help. Brighthouse timed out and another msg was saying that the email address I was sending as had to match the email address of the authentication and that didn't make sense as I have only had one address & (typed correctly in all places). I have called Spectrum more than once and asked for an upper level, however, they were no help at all saying they have no resp. for 3rd party etc. I HOPE YOU CAN HELP SOLVE THIS MYSTERY. Thank you!

A new problem since July 1, 2024 Thunderbird keeps crashing on start-up when checking for new mail. HELP!! Crash ID: bp-e8be7291-7fe9-41c0-bd21-45d860240702

I have received an email from Microsoft informing me of changes to its authentification procedure. As from Sept, to continue using Thunderbird to access my outlook/hotmail accounts, I have to change the authentification method to Oauth2. The reasons and changes required are detailed here: https://support.mozilla.org/en-US/kb/microsoft-oauth-authentication-and-thunderbird-202 I have 2 problems. 1. imap-mail.outlook.com - I can change my authentification method to Oauth2. However, when I then try to access my mail via TB, I get an error stating that the server imap-mail.outlook.com does not support the authentification method! (see image) 2. Outgoing Server SMTP There is no Oauth2 option available to choose!

Can anyone help? I am using the most up to date version of Thunderbird 115.12.2 (64-bit).

Microsoft is changing the authentication method for outlook mail to OAuth2. I follow the guide provided to update Thunderbird, but my version of the program does not have OAuth2 as an option. My outgoing server is smtp-mail.outlook.com, but OAuth2 is not an option in the dropdown for authentication method.

Error message:

"Sending of the message failed. An error occurred while sending mail. The mail server responded: <ec2-54-219-72-248.us-west-1.compute.amazonaws.com[54.219.72.248]>: Client host rejected: NO THANKS. Please check the message recipient "patrick.gilroy@harmonydesigninc.com" and try again"

Occurs regardless of recipient, whether replying to an incoming email, or composing a new email.

Not always, but frequently when I delete an email from an inbox, the other emails are hidden for awhile. This occurs whether I am pressing Del while the email is visible, or pressing Del with the email selected in the Inbox. If, however, I immediately open another folder and then re-open the inbox, all emails are instantly visible. Am I doing something wrong, or is this a "feature"?  ;-) Regards, Dave

have been using Thunderbird mail for about 3 years. It’s template selected the incoming and outgoing servers and ports etc..successfully. I've been connecting to Prodigy mail/ATT I had to change the battery and it doesn't work anymore. Can you help ???it checks the password until it shows an error message that the servers password or etc are wrong. I know the password is right since I can log in directly. Messages :

1- Configuration found in ISP Database

2- Checking Password (for a few minutes

3- Unable to log in at server..probably wrong configuration username or password

4 then nothing

Worked great before battery change
