Thunderbird Support Forum

I'm on MacOS Monterey 12.7.5 with Thunderbird 115.12.2 (64-bit). I noticed two problems. First, the message Window cannot be moved to a different location. And second, the "ToolBar" with the "send" button is missing in the message window. I can't recall what I did to cause these two problems. Question: Is there a fix for my problem? Any help is appreciated. Thanks. Roger

Hi, I've received the email below from Microsoft today.

I have 15 email accounts linked to Thunderbird mail and use up to 5 of them daily. Sometimes 'instant' communications on one or more of my accounts can be important.

Will Thunderbird mail still function in the same way from 16th September?

I apologise if this question has been answered somewhere else. I searched but could not find it.

"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."

Not used Thunderbird for about a week as was away. On my return I am now getting duplicate downloads every-time I open Thunderbird on my desktop using Windows 10. I am on Thunderbird version 115.12.2. I have been using Thunderbird for a long time and this is the first time this happened.

I recreated the global-message-db.sqlite indexfile, turned off my anti-virus, compacted folders but nothing solved the problem.

However I did find a similar question on this site with a solution which wasn't exactly the same but lead me to investigate the Mail folder in my profile. I see I am getting duplicate pop.gmail.com folders (pop.gmail.com, pop.gmail-1.com, pop.gmail-2.com, etc.). I guess that is probably connected to the problem.

When I open Thunderbird I also get the message 'Connection to server pop.gmail.com was reset'.

Any help would be appreciated. I didn't want to delete any pop.gmail.com folders without expert advice.

Thank-you in advance.

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).

I have a brand new install of Thunderbird, and I want to import .mbox files that I converted from Outlook .pst files.

I have seen many support articles saying that to import .mbox files, I need to use the "Local Folders" option in the Folders menu on the left hand side of the main page. I have added the ImportExportTools NG plug-in, but I don't see a "Local Folders" option on my main page.

I must be missing a step. I have attached a screen shot.

Thank you for your help.

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.

I am using Windows 10 Home on an HP laptop. Some months ago, I began getting this error message when trying to start Thunderbird: Your Thunderbird profile cannot be loaded. It may be missing or inaccessible. I've been slogging along using my Gmail reader since then but I need my address books from TB for my business. I really need to get this fixed.

I've read all the questions/replies on this and have uninstalled and reinstalled TB. My Appdata/Roaming/TB file only has 5 files in it: Crash Reports, Pending Pings and Profiles plus a couple of 1 KB config files. Don't know if this is right or not.

When I search the Profiles folder using .ini, I get this Notepad info:

[Install8216C80C92C4E828] Default=C:\Users\*\Documents\yvfr1fi4.default Locked=1

[Profile3] Name=thunderbird IsRelative=1 Path=Profiles/kavosmqu.thunderbird

I have this yvfr file on a thumb drive and I tried uploading that into the roaming/TB file but I still get the same error message.

Any help greatly appreciated! Thank you.

I back up my TB profile every few months. I just went thru the Cox-Yahoo email conversion and I am getting emails. When I did my back up, I noticed in the properties it had one more folder and the files went from 1311 to 2585 files. Is something wrong? Do I need to compare and research what is causing this or just move on!

I recently changed my google account/ gmail password. Since then I cannot send gmail via thunderbird. (I can send others hotmail etc) I can receive mail. I can send gmail via the gmail web browser. Sent gmail mail then shows in thunderbird.

I get the following message when sending email in thunderbird: Login to server smtp.googlemail.com with username sjagutpal@gmail.com failed. Enter new password I enter my new password. Fails again.

Sending of the message failed. Unable to authenticate to Outgoing server (SMTP) smtp.googlemail.com. Please check the password and verify the 'Authentication method' in 'Account Settings | Outgoing server (SMTP)'

note: IMAP server settings is OAuth2.

please help ?

Many Thanks...

How do I include a newly made email account so that it will appear in unified folders? I thought that when the new email was added to Thunderbird it would automatically show in Unified Folders but it does not.

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?

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.

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 composed an outgoing email message that I wanted to keep for future use, and saved it as a Template. That not only saved it under the unified Templates heading, but created a second appearance of my main email account with its own Templates subfolder. At that point I decided I really didn't want to keep it after all, so I deleted the message, but the second Templates folder didn't disappear; its still on the tree list as an empty folder. Right-clicking that folder doesn't have a Delete function, but it does present a Repair option, but running that doesn't help. How do I get rid of that unneeded individual email account listing and the empty Templates folder?

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.

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.

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!

Please Someone help ?

I have followed all the suggestions I can find, but my Thunderbird Calendar will not sync with the Outlook Calendar on Windows 11. I am using TB Sync, but every time I try to add my Outlook Calendar ? It refuses to accept my Password, even though it is correct, and the User name and email are too ! It shows as error code 401, and cannot authenticate ?

I have tried a suggestion to create an 'App Password' to use in my Microsoft account, but the options described do not exist in my account !

Can anyone please help ?

There's an article that says we can change where attachments are stored by going to tools, options, attachments. However, I have no "options" under "tools." Thanks in advance.

Microsoft sent email last night announcing the end of "Normal Password" for Hotmail, and warning that Hotmail would REQUIRE "modern authrentication" beginning 9/16. I have personal desktop subscription to Microsoft 365. I have set Microsoft account to 2FA and checked in Tbird that cookies are enabled.

I have spent hours and days trying & failing. With server imap-mail.outlook.com using OAUTH2, Thunderbird won't sync and shows message saying that server doesn't support the authentication protocol please enter another one. With 2FA still turned on and using Normal Password setting and entering an App Password from Microsoft, the Imap connection is fine about 85% of the time, needing re-entry of the App password about once a day or so (usually requires several tries until App Password gets accepted.)

The 0AUTH2 fails with Norton Smart Firewall turned Off or Turned On-makes no difference.

(Sending email with Outlook and 0AUTH2 DOES work okay.)

I've also tried Imap connection with a different server: Outlook.office365.com, using 0AUTH2.

In this case, Tbird shows me a Timeout error and never makes an Imap connection to the server.  

I've been limping along with the app password, and "normal password" authentication, but now Microsoft announces they will stop accepting connections that are not 0Auth2 ("modern authentication") from Tbird or any other software after 9/16. The clock is ticking. I've tried every remedy I've seen online from Tbird or from Microsoft. Nothing has yet allowed a QAUTH connection for Tbird to a hotmail IMAP server. Please help! !
