Dear Support,

we want to intergrade Thunderbird to our Microsoft 365 (Exchange Online), but we have massive problems with the authentication of our users.

I have allready configured an the Enterprise Application for Thunderbird in Entra ID and the Clients, excactly as documented in you article: https://support.mozilla.org/en-US/kb/microsoft-oauth-authentication-and-thunderbird-202

We have conditional access policies in out Entra ID, which allow only comliant devices to acess out Exchange Online.

The Thunderbird clients are running on these compliant devices (Windows ans macOS), but it seems that the client is not passing this information through the Oauth authentication (see screenshots 01 to 04 - I uploaded the configuration and all the steps of authentication).

I searched the internet for more then 3 days, but the only thing that I have found about this problem is this: https://bugzilla.mozilla.org/show_bug.cgi?id=1697805

In our Entra ID, we see in the sign-in logs, what excactly is happening with the conditional access (screenshots 05 to 07)

We use the newest client versions of thunderbird.

Can you please help me on this? We realy want to continue to use Thunderbird!

Kind Regards Ioannis Kyriakidis

I have Thunderbird Bets and want emails when opened to be in a separate window as non Beta does. In Settings I've selected "Open messages in - A new message window, but some emails don't wrap text to fit the window but instead have a width & height slider.

Can the Thunderbird Beta software display open emails in a separate smaller window as a default - and more importantly with wrapped text? Geoff

I think that I need to completely uninstall TB Something went wrong on one of my computers, and it couldn't connect to the server. It works on my other computer.

I decided to uninstall TB that had the problem. I did that, but when I reinstalled it, it had all of the same settings and problems. I used RevoUnstaller. because it said When I reinstalled it, all of the stuff and the problem were back.

What is the best way to fix this?

I have two email addresses on Thunderbird. One is working fine while the other Jwhite7@shaw.ca quit loading on April 8th, 2024. Do not know what happened. Need help

Hi,

My issue is that my Thunderbird sent folder is not showing any emails that I send from my iphone or ipad, whether I use the native Mail app or the Microsoft Outlook app. I can't find these sent emails in any folder in Thunderbird.

I'm using an Exchange email account from my university. Using Thunderbird 115.11.1 (64-bit) on Windows 10.

My iphone and ipad are running iOS 17.5.1.

Emails sent from my iphone or ipad do appear in the sent folder on my university's webmail interface which is outlook.office.com.

If this is relevant. in Thunderbird's "Account Settings" under "Copies & Folders" it's set to "When sending messages, automatically ... Place a copy in ... "Sent Folder on ... <myemailaddresshere>" -- if that helps.

I searched but haven't found any information online about this issue.

Thank you,

kate

Hi!

What is the way to tell thunderbird to index IMAP folders in global-messages-db.sqlite which are not stored locally?

And a more generally, how does this part work, message indexing and remote IMAP folders not stored locally? Here, after removing the database, thunderbird indexed only some very limited set of IMAP folders in the Gloda, but not all of the folders, despite all are checked for "Include in global search". Or maybe it didn't even index whole folders, - I can't say for sure.

Thanks,

Please help me with bt password . its not being accepted. new one not excepted either .old ones not accepted. What can I do? I have maybe important emails I cannot open. Please advise me in simple steps please.

Using Thunderbird 115.11.0 (64-bit) on Manjaro (Linux - fully updated). Thunderbird is a great and fantastic email client and I will always appreciate Mozilla for its principals.

I'm using IMAP and I moved some messages from a Gmail account to another IMAP account and somewhere along the way, an additional 10,000+ emails have been duplicated (about one third).

How can I systematically remove duplicates without the use of an add-on? The reason I don't wish to use an add-on is because every add-on I've found requires the following permission Have full, unrestricted access to Thunderbird, and your computer. and that is absolutely terrifying.

Are there any remedies for (systematically) handling duplicates without handing over all the keys to the kingdom?

TWO issues: 1. TB use to display emails in the INBOX immediately. Now I have to click another folder then go back to Inbox for the emails to be visible.

2. Emails with the red flame are junk emails. I think those use to automatically go to the Junk folder but now they're showing up in my Inbox and I have to manually send them to Junk folder. Am I wrong on this or has something changed?

I have the Select Messages column switched on, with its handy checkbox for selecting multiple messages, usually for deletion or filing out of my inbox.

This works perfectly except that a collection of selected messages will instantly become unselected if the user clicks on a message instead of inside a checkbox.

In my head, if there's a checkbox it should be sticky -- in other words, the only way to deselect all selected messages would be to use the "deselect all" checkbox at the top of the column. In its current form, it's actually easier to NOT use the checkboxes and hold down the ctrl key instead, to select/deselect odd messages.

The existing behaviour seems so odd that I wonder if I've missed a configuration step somewhere. But if this IS the way it is, can I ask the devs if they might consider taking a look at this behaviour and finding a way to improve it for the more shaky-handed amongst us?

Hi, after a 2 week that I can't read mail from Thunderbird (115.11.1 64-bit), today I have found the old mail are blank in field From, Subject, but not in date. The body of email is the source of whole mail in plain txt (see image). What's happen? Is possible to retrieve email in correct format? (I have a backup, but I have some fear about new message discharged today) I use TB from 2005, and in the last 8 Year in portable version with decentralize storage and a copy synchronized of preference between Windows at work and Linux at home. Some one can help me?

Thunderbird is blocking some outgoing mail. If I start with a file, right click, send to mail recipient; the message is blocked as spam with this diagnostic: Sending of the message failed. An error occurred while sending mail. The mail server responded: Spam detected by content scanner. Message rejected (ID 6661B68A00783926). Please check the message and try again.

But, if I start with Thunderbird Write and attach the same file, there are no problems and the message is sent.

Thunderbird version 115.11.1 (64-bit)

I belong to a group of 11 people, and one or another of us occasionally sends a group email around to everybody. Those emails usually call for responses to some question or issue involving all of us.

And here's my problem -- sometimes when I hit REPLY ALL, my reply goes out showing someone else in the group as the sender, not me. That can lead to confusion, of course, as the others in the group will think my reply came from that someone else. Anyway, I include a couple of screen shots. And I deleted from the images any info showing my address or anyone else's. I did leave the usernames, so that I can explain.

They are "Fletcher Lokey" / flokey and "Susan Dyment" / sdyment.

First one (1.jpg) shows what I see when I click REPLY ALL. You would expect my username and address to be showing at the top, but it's Susan Dyment's name and address. AND, at the far right end, you see "flokey", which should not be associated with Susan Dyment, I would think.

Second one (2.jpg) shows what I see when I click that small "down arrow" at the far right end of the box. My username and address are then seen at the top of the dropdown, circled in red. But the entry for Susan Dyment is the one selected at the start. When I select my info, things get straightened out. I also have a gmail account, which is showing as the third option in the dropdown. That's only there because it was part of the experiment I did so I could get the screenshots

So I have to be paying attention, so I can correct it if it happens.

I've hunted through my address book for any clue to why Susan's info is the one selected when REPLY ALL is called. In fact, I'm left wondering why anyone EXCEPT me would be in that dropdown box. And why in the world does Susan Dyment have "flokey" associated with it there?

I hope that's not too confusing. And any help appreciated

The battery in my laptop went flat while Thunderbird was open. When I re-started it and re-opened Thunderbird I had lost my Newsgroup Subscriptions. I can understand some issues but loosing all subscriptions?

Hi, I seem to be having trouble syncing. I have an account which has 25 years' worth of emails on it, organised into folders. I reorganised the folders, and now on thunderbird they appear empty even though webmail shows them to contain emails.

I have tried going offline and downloading messages, changing my password, restarting, and clearing the startup cache.

How do I fix this, please?

Recently I have been having an issue where all new incoming message to my primary email account will also end up in the inbox of my secondary email account. So basically, when I open Thunderbird and say 45 new messages appear in the inbox of my primary account (myname1@provider.com) those same 45 messages will also end up in the inbox of my secondary account(myname2@provider.com), even thought the messages were only addressed to the primary account. I checked to see if this was an issue with my internet provider, but when I check messages on their webmail, it only ends up in the correct account. Thanks for your help.
