It must have been one of those nutty "...something I did" things that made a second account identity appear one day. I use a Unified Folders mode exclusively, and the subject account is my primary account (identical to the first Unified listing), but some action on my part made it pop up below as well, just above 'Local Folders.' The only subfolder under this redundant appearance is 'Templates,' which is empty. The unwanted appearance starts out in a blue font, but turns black (as shown below) once the 'Templates' folder is clicked on. Can I get rid of this somehow?

Suddenly today, about 1/2 to 2/3 of the emails that have been in my inbox are unreadable (see font below). I tried doing the Properties>Repair but no change.

Server Type: Owl Server Name: outlook.office365.com Thunderbird: 115.3.1 Windows 11 PC.

Perhaps related or not: today the Inbox folder didn't display in its usual location (instead of displaying directly under the email address, it was was down after templates, deleted, etc). I dragged it up where I wanted it. But now many of the emails are unreadable (but not all of them).

Any suggestions?

I have two problems tha occur when using the Unified Folder tree view.

1) The view of Local Folders that appears in the Unified Folders view (which I use and require) has lost all subofolders except for Outbox. In particular, it does not show Sent Copies which is folder I rely on.

However, Sent copies and several other subfolders for Local Folders are visible in the All Folders View. As a workaround, I am currently set the tree view to show both Unnified Folders and All Folders to have access to Sent Copies in local Folders...but this is a pain because it means I have to scroll far, far, down in an excessively long folder tree to find Local Folders/Sent copies.

So the solution I'm seeking to number 1: Restore Sent Copies, and other normal subfolders, to the view of Local Folders that appears in the tree when the view is set to Unified Folders. (Closing TB, Deleting the Smart Folders from the Mail folder and re-starting TB does not solve or have any effect on this problem. See my conjecture at end below).

Second problem is: I'm seeing a big handful of duplicate emails showing up in the Unified Folder Sent folder. I've cleared up most of this problem by deleting Smart Folders from the Mail Folder in the profile...but this repair fixes most, but still permits a handful of duplicates to remain, especially in the Sent folder. I have been running TB happily for maybe 10 years. Current setup is Windows 10 on a Lenovo desktop....my two mail accounts are Hotmail and Gmail.

I'd be very grateful for assistance with these problems.

My conjecture about these problems: They arose in past month while there were a lot of starts and stops and edits of settings for TB in past couple months in order to keep TB connecting to Hotmail. That finally got solved a week or so gao... but my conjecture is that some program crashes thar arose while editing TB sedttings may have contributed --at least to the missing subfolders n the main or Unified view of Local Folders.

I have been trying to get help with Thunderbird for an issue with not receiving my emails and not being able to send any emails since June 12th of 2024. Nothing has worked with the little support from this site. Please help!

Hi, I am hoping to have two thunderbird downloads/accounts on the same computer.

ie can I run 2 separate thunderbird portals -

one for my talktalk emails

and a completely separate one for my gmail/google accounts.

I know I would be able to load the gmail/google onto my original Thunderbird account (but I would like to keep them completely unconnected)

Thanks in anticipation, HM

I'm currently using Thunderbird 115.7.0 (64 bit) portable version on Windows 10. For many years I have ordered my emails by using subfolders, with a large one called 'Archives'. When another folder such as 'EE' becomes non-current I simply drag and drop it to the 'Archives' folder. However now the archives folder is so large and irrelevant that when searching for emails, I get thousands of results from up to 15 years ago. So, how can I archive emails so that they are easily accessible, but so they don't come up in an all encompassing "All folders" search?

to select two or more messages on the message pane, one method is to hold down the CTRL key and left click on the messages you want to select. This has stopped working on my Thunderbird. When I select a message and then go on to select the next message, the first message I selected is deselected. So I can only select one message for an operation, e.g. "move", "delete", rather than a group of messages.

Outlook says that it will no longer let third party mail apps like Thunderbird to access Outlook email as of September 16, 2024? What do you recommend?

"Action Needed – You may lose access to some of your third-party mail and calendar apps

Update your sign-in technology before September 16th, 2024 to maintain email access.

The safety and security of your information is top priority for Microsoft. To help keep your account secure, Microsoft will no longer support the use of third-party email and calendar apps which ask you to sign in with only your Microsoft Account username and password. To keep you safe you will need to use a mail or calendar app which supports Microsoft’s modern authentication methods. If you do not act, your third-party email apps will no longer be able to access your Outlook.com, Hotmail or Live.com email address on September 16th.

What do you need to do?

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.

Microsoft provides free versions of Outlook for your PC, Mac, iOS, and Android devices which can be easily downloaded and connect to your email account. Using an updated version of an Outlook application will ensure you are connecting in the most secure way.

How can you set up your Gmail, Apple Mail, or other third-party mail application?

Various non-Microsoft applications will have their own steps for connecting to your Outlook.com email account using modern authentication methods. See our help article - Modern Authentication Methods now needed to continue syncing Outlook Email in non-Microsoft email apps. However, you may need to contact the creators of those applications to provide you with instructions. In many cases, simply removing and re-adding your account with the latest version of that application will configure it to use modern authentication methods.

From Sept-16-2024 Microsoft will deprecate Normal Password and require OAuth2 authentication on its email accounts accessed from Thunderbird and other clients.

I'm trying to convert my hotmail accounts on Thunderbird to OAuth2 authentication.

Server Settings Authentication can be set to OAuth2 because OAuth2 is an option in that menu.

But SMTP Server Authentication cannot be set to OAuth2 because OAuth2 is not an option in that menu.

Both Connection Security methods ( Inbound and SMTP ), are set to STARTTLS.

See screenshots, thank you.

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.

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 telling me I need to open a ticket with Thunderbird while I work to address the problem with my microsoft tenet. Basically, I don't seem to be able to get any of the member accounts on my tenet to be able to use thunderbird with their organization email account. Any tips from Thunderbird would be helpful.

I have been able to set up thunderbird for the Admin email for the tenet and it is working.

I just can't seem to get the Microsoft settings right for the other email addresses in the tenet to be able to use any email client other than Outlook.

Microsoft tell me that I must use OAuth2 for my accounts, else I'll be locked out.

Server is imap-mail.outlook.com. If I select OAuth2, then I can't receive emails unless I reset back to Normal Password.

I'm also supposed to set my SMTP server (smtp-mail.outlook.com) to OAuth2, but this isn't an option on the drop down list.

Help, please!

why does my hotmail in thunderbird sometimes get my emails and other times it says "Sending of password for user *********@hotmail.com did not succeed. Mail server pop-mail.outlook.com responded: Authentication failure: unknown user name or bad password"? Then it starts getting them again. It's totally random. Every once in a while it does it with my .live email too. Yet other .live and .hotmail addresses never have a problem? TIA

Hello, In my work email account (Zimbra instance), very regularly new emails keep reappearing as unread even after they are marked as read. If I restart Thunderbird, or if I go offline then online again the problem is solved; however, I would like a more definitive solution.

When the problem occurs, in the console I can see "The current operation on 'Inbox' did not succeed. The mail server for account X responded: mailbox selected READ-ONLY.". I tried solution suggest at https://support.mozilla.org/en-US/questions/1276757, i.e., setting `mail.server.default.send_client_info` to `false`, but it did not work. Any other suggestion?

Heya:)

I am a webdesigner and I'm currently designing a website for a client that uses Thunderbird for his mails.

Previously, Domain, website, and email had been hosted with the former agency.

Now we are gonna split this up into 3 different providers:

Webhosting: Squarespace Domain hosting: Cyon.ch E-Mail hosting: Would be great to keep using Thunderbird :)

How can I ensure that my client can still use Thunderbird? Do I just need to change some DNS-records? Otherwise I will have to switch to gmail :(

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.

I moved some emails to a folder from the inbox and now they are not displaying. when I search them I am able to find them and can be read, the search indicates that they are in "the new folder" all mail and important. This has happened before and I have not been able to resolve I am assuming there must be a setting I have activated/deactivated but I've no idea what. I am FAR from tech savvy so please give any answers in as simplistic form as possible. Thanks Matt

Hello

I created an Archive directory within Local Folders, and within that have stored years of emails.

As of yesterday, when clicking on any given sub directory within the Archive, Thunderbird says that there are 0 messages to display.

All of the .sbd and .msf files are present when I browse the Archive structure in my user profile in Windows Explorer.

The problem seems to be that Thunderbird can read and display the directory structure, but cannot display the emails contained within it.

I do not have a backup of the profile directory (yes, I know!).

Can anyone offer a solution that will allow Thunderbird to display messages that seem still be present ?

With thanks in advance
