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

I cannot get the print button to work in my emails. I used to be able to close Firefox and re-open and then it would work, but today that did not work. I shut down my computer completely and still it does not work. I am attaching a snip of the screen showing the print button.

The folder "popstate-1.dat" appeared under my email account below Inbox, Drafts, Sent, Archives, Junk and Trash. I have attached an image showing the folder located below Trash and above Local Folders.

Can it be deleted? Is it serving a purpose?

I recently deleted old messages from the various Local Folders folders.

Thank you.

I have no idea how to fix a problem that just emerged in the last hour.

I can't download file attachments sent by email. Yesterday I could. I have been using Mozilla Firefox as my browser for more than 10 years. I tried restarting my computer that didn't help.

Every time I sign into something using Firefox the recaptcha does not allow me to continue. If I switch to Google Chrome it works. Please help me to be able to use Firefox.

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?

When I'm browsing, especially when shopping, say, Amazon, eBay, or Swanson Vitamins or wherever, FF opens a new tab which remains open to the right of the left-most original tab. Of course, when I + a new tab which I want it to stay open, it opens and, again, by itself, FF closes the first tab and the latter takes over the left-most spot. And, in case of eBay, when I click on an item I want to check, it keeps on opening a new tab on the original tab. Placing the cursor on FF icon on task bar displays all the tabs. I never had things like above happen with previous issue FF. Of, course, I don't know since which FF version was stable in the way I wanted. Does anyone know how to set FF to stop taking all these unwanted actions?

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?

There is a hacker who accessed my Google account via Firefox about 10 hours ago, with the result my language setting has been switched to Korean. I live in Hong Kong and have never been to Korea, and I do understand Korean at all. Can you help pls? Thx.

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?
