We just signed up for a Microsoft email account this weekend. Preferring to use TB, everything seemed ok as I was able to receive emails just fine, but upon trying to send emails, I continue to receive an error message saying "Login to server smtp.office365.com with username tom@callablefirst.com failed".

I have gone through many different troubleshooting techniques I read about in the community and here is a checklist of things tried:

1. Checked that IMAP is toggled on in 365 admin 2. Checked that TB is accepting cookies and no exceptions are listed 3. Tried changing SMTP server to recommended instructions from Microsoft and verified all settings are OAuth2 4. Enabled 2F Authentication 5. Used config. edit to clear out all existing OAuth2.scope files

I have downloaded a different email client- eM client and everything works fine sending emails from that end so I am convinced this has nothing to do with my password being entered incorrectly, but some unknown conflict that isn't getting resolved between TB and the 365 account. I prefer using TB but am getting to the point where this is taking a lot of time away from other business activities that need to get done.

I have my marketing guy trying to remotely help figure things out, too, but he is at a loss as well.

Let me know if you have any ideas, thanks, much!

I just returned from 10 days without using thunderbird.

When I try to download my messages I get stuck on "loading message" and Thunderbird says it is "Not Responding"

I lost my email format and now, when I open Mozilla Thunderbird the only thing that comes up on my screen are all of my SENT emails. How can I get back to the email starting page with which I am familiar and can I keep the emails I've received over the past years? This is very confusing and I don't know how it happened. I've clicked on all of the icons I have available to me and none of them seem to offer any help. I clicked on "restore original columns" but it doesn't take me back to the original email start page. Any ideas?

Email provider is Microsoft 365 (via GoDaddy). It is set as a POP account on Thunderbird and all works correctly. When Thunderbird downloads new emails, they correctly show as "Unread." But on our phones (both iPhone and Android) the emails appear as "Read." This occurs even when the email are unread on Thunderbird. If Thunderbird is closed and a new email comes into phone, it correctly appears as "Unread" on our phones. But when I open Thunderbird and that same email gets downloaded (but not selected or read) the email becomes "Read" on our phones. I have gone into both Outlook and Thunderbird and have deselected any options that would automatically mark emails as read. This is annoying because, if Thunderbird is open on my computer, when I look at my phone, I get no notifications of unread email.

For years, I've used TB to keep all my e-mail communication in my own computer. Since our local provider (Frontier) switched over to Yahoo, I had to change my server info to IMAP (yahoo), and I can no longer view any of my old e-mails. Is there a way to access these? I have MANY that are related to my business. Thanks!

I imported a bunch of emails we recieved (EML Files) into Thunderbird, however Thunderbird is not showing me the correct date of the email. In the "Date" column as well as the "Recieved" column it is noting the day I uploaded the emails to Thunderbird. It is imperative to get the dates corrected.

Migrating to Linux after the latest Copilot/Recall issue yesterday.

Setting up Thunderbird for my Microsoft O365 accounts (I have 5 companies I support).

Automated setup for IMAP/SMTP was smooth and no issues. All settings are correct within the application itself. I'm an admin of 3 of companies for O365, and I can confirm that the settings in the app are set correctly.

However, when attempting to send the application will not forward the message. No message inside O365 to indicate why not.

I hae about 6 email accounts managed in thunderbird (most recent version). When I try to unsubscribe from a spam email and it wants me to enter my email address to unsubscribe, a drop down list containing my various accounts appears. Unfortunately there is one entry in the list that is not one of my accounts and I cannot delete it. How do I get rid of it?

Hello,

some messages in my TB (128.3.0esr [64 bit]; macOS 15.0.1) do not show any content or show only completely random numbers, letters and other characters. Sometimes what helps is moving messages between the folders.

There is not such problem when viewing the e-mail via webmail.

Please find attached screenshot.

Kind regards Marcin Ćwiertnia

Hello, both my wife's and my thunderbird are not connecting to the Frontier/Yahoo email server. When I click Get Messages there is no indication in the information bar that it is trying to connect. Note this is on two different PCs. After a while I get a timeout message. Thanks for any help you can provide.

My spellcheck used to use the enter key to accept choices. Now I have to use the cursor to accept the proposed choice or a choice from the dropdown of possible choices. This means a lot of cursor movement.

I have an IMAP account using Thunderbird. My email folder tree included a folder named Farmex Shows & Conferences. It was there a couple of weeks ago as I saved an email to a subfolder in it. Then the main folder referred to above disappeared. I have been in tech support correspondence with zoho who host our email system. They do not appear able to help. Is there an explanation for this folder going missing? Can it be recovered? Is it possible operator error has deleted it or moved it?

When I start a message to a person and start to type their name, Thunderbird offers me a list possible folks. Sometimes, it offers me an multiple candidates, SOME of whom are not (or not longer) in any of my address books. Why is that?

Hi, since 9/30/24 no emails have been loaded on Thunderbird. Has a new update caused this problem? I am running the most current one, 128.3.0esr. Thanks for your help! Nora

Hi, We absolutely don't want the Microsoft Outlook mail program that they are forcing on Windows Mail users. I can no longer access my emails through that program.

We need to know the key features of Thunderbird and if possible how it compares to the "NEW" Outlook amil.

I ask the comparison in part because we mainly don't like the forced use of the "cloud" aspect to their program and apparently having to sign in to it every time I try to open Windows mail.

Your prompt response is appreciated as I can no longer access our two personal email accounts through Windows Mail.

Thanks Dave

I found an interim solution to the problem of the corrupted PDF files by Thunderbird Nebula, as follows:

take Thunderbird offline - move the email with the corrupted PDF attachment to Outlook Archive folder - put Thunderbird back in the online modus - move email from the Archive folder to the Incoming Post folder
