From the article "Microsoft OAuth Authentication and Thunderbird in 2024" there is a screenshot showing a OAuth2 option for the SMTP server setting with STARTTLS connection security. It does not appear for me. There are only the five options, as shown in the screenshot. How do enable the option to be available in the drop-down list or set it?

The available options are:

No Authentication Normal Password Encrypted Password Kerberos / GSSAPI NTLM

I am on Thunderbird version 115.12.1 (64-bit), Windows 11, version 23H2, build 22631.3737

I have email service with 1and1.com. I have been using thunderbird (TB) in conjunction with my 1and1 email service of over 20 years. I currently have several 1and1 email accounts set up and working fine on TB. The problem is, I cannot add a new 1and1 email account.

Yes, I know exactly how to add a 1and1 email account to TB. I have been trying for days to add a new account, to no avail. All setting have been checked, double checked, triple checked and quadruple checked to the point of insanity. Everything is set up correctly. Here is what happens.

1and1 accounts have to be set up manually. After entering all the correct settings manually and pressing enter, I get the error message; :thunderbird failed to find the settings for your email account". The account set up box freezes at this point and will not retest the settings no matter how many times I press the Retest button.

As I have already stated, I have other 1and1 accounts setup and working fine on this install of TB. But I have tried truing off my firewall and anti-virus anyways. But to no avail. Also, this account was installed and working fine on a previous install of TB on this same computer. My Hard drive died and I am in process of recovering from the crash and getting the new drive and OS all setup.

Any help would be appreciated.

P.S. here are the 1and1 settings for TB. https://my.1and1.com/mail-client-setup?mail-id=129929150&mail-address=explorer%40thejungleexplorer.com&mail-account-id=161742979&mail-type=BASIC&linkId=ct.btn.email-account-details.table.setup-email-client#

The inbox had about 18 months worth of emails. I deleted three emails that had been flagged by Thunderbird as spam. Then I went to the trash folder and permanently deleted the trash that included many other unwanted emails.

When I returned to the inbox, the full list of emails was present but after clicking on any email there was no email content shown. A new email came in and the content was shown for that email.

The sent folder still shows all the sent emails.

After looking for solutions on the web, I selected the inbox, right clicked and opened properties. I then selected "Repair Folder". Now, the only email shown in the list is the new email that came in after the issues started.

I have looked for crash reports and it says there are no crash reports.

Suggestions....? Thank you, Peter

I have an IMAP email account with Virgin Media. I have been backing up my Thunderbird email as follows (not sure where I found this method) WIN + R %appdata%/Thunderbird/ Ctrl A Drag all files to External Hard Drive When I open the Backup file there are two files Open 62hcjzp7.default-release (whatever that all means) there are loads of folders one being MAIL Thus contains all my folders from Local folders For every one there is a File and an MSF File How do/Can I restore these to my current version of Thunderbird? I have tried Import from another Thunderbird installation, Profile folder Open the back upp and Select Profiles Tick Mail messages. It says Compete but never copied anything It does create an empty folder under Local Folders in Thunderbird.

My question is can I restore from this backup? If not, what is the best way to backup and restore Thunderbird? Bill

That is the actual email that is has been sent, received, and saved. I don't want to lose it for legal reasons. Also will the address book sync with my Google contacts?

On my workstation the Thunderbird e-mail data is saved in the C:\Users\[My Name]\AppData\Roaming\Thunderbird... directory.

The data consumes considerable hard drive space and I would like to create a directory on my F: drive (that has 100+GB of data free) to "off-drive" the data. If it's even possible, how do I configure Thunderbird to use this different data directory on a different drive??

BTW, I tried to do this by copying the data/profile in the above C: drive directory to my F: drive. I changed the "Local Directory" setting in the "Message Storage" pane on the "Server Settings" window in the "Account Settings" appropriately. I even changed the path in the profiles.ini file in the default C: directory. This process didn't work and resulted in Thunderbird demanding that I create a new account. All returned to normal when I copied the Thunderbird data to its original location.

The add-ons for removing duplicate emails in Thunderbird do not work for the latest version of Thunderbird, 128.0

Anyone know how I might search all my emails for duplicates and decide which ones to delete?

I have been using Thunderbird with multiple POP accounts for about 15 years with few problems.

Since upgrading to the latest version, with was about a week ago, emails are downloaded again and again, for as long as they remain on the server, which is for most accounts 7 days.

I can see the emails are marked as read on the server (my host is X-10 Infinity and been using them for 4 years), but every time Thunderbird connects to the server, it downloads all the messages again.

My mailboxes are filling up with duplicate messages, sometimes 10+ copies of each one. I haven't changed any settings on the server or in Thunderbird, so not sure what is causing this.

If I click to Get Messages manually, Thunderbird only downloads 1 or 2 messages, if anything. But for some reason when the scheduled connect runs (for example: every 30 minutes) it seems to pull down all messages in the POP mailbox again and again.

Is there anything I can set or change to fix this please, or is this a bug you are working on?

I really don't want to change so I download messages from the server and delete them immediately rather than in 7 days as this allows me to have a backup in case my computer needs to have a re-install.

Thanks for any help. I'm sure I'm not alone with this problem.

Good morning Windows 10, TB 115.11.0 32 bit. Multiple email accounts, some gmail, others like sfr, lol and free. All accounts use POP. All working before weekend, shut down the PC. Monday morning, opened Windows, all seems there except TB which has a screen with an Account Setup tab inviting me to set up an existing email address. Close that tab and the attached screen image appears, open tabs blank, no accounts pane on the left, no emails, no local folders. Nuffin. Restart TB and Windows, twice, still Nuffin. Look in Profiles, yes, under Mail all profiles appear to be present and the correct size. Going to gmail’s on line email system shews account open and receiving email normally. I had a problem a month ago after a TB update when all accounts were present but no emails were displayed. I changed the password to 0auth and recovered my emails. That took three days to resolve and I lost a business client through the delay in responding. Today I must file several court documents or I shall be in deep poo. Any suggestions how to recover the left hand accounts pane and see the accounts and folders will earn my undying gratitude.

I very very recently upgraded to Windows 11, but even though I have Firefox and Thunderbird running with no problem, when I click on an email address on a website, instead of going to Thunderbird, I get some Windows email app that I never saw when just a month ago when I was still using windows 10 clicking on an email address would bring me right to Thunderbird. How can I get Windows 11 to use Thunderbird and only Thunderbird. I am not a techie, so if you know a solution, please be as clear as possible. Thank you.

When sending email thru Thunderbird on PC, sentbox always shows emails sent twice (but only received once).

If I send email thru my phone, sent mail shows sent only once, so I know it's a problem with Thunderbird.

Any ideas?

Recently, my College switched to Outlook 365 mail.

I'm running the latest 64 bit Thunderbird on Windows 10.

We use OAuth2 for incoming and outgoing.

Incoming server is outlook.office365.com. OAuth2 is an authentication option. Fine. I use Microsoft Authenticator, and it works.

But, Thunderbird will not or cannot use OAuth2 on the SMTP sever, smtp-mail.outlook.com. It simply doesn't list the OAuth2 option. Even if I go back in and try to edit the server, it won't give me that option.

Other clients detect it fine.

Hi all,

Two days ago, copies of messages I send stopped being automatically saved to my TBird SENT folder. This is the case whether I send the messages to myself or other addressees.

I use Windows 10, TBird 115.6.1, and Gmail (with POP3 for the affected account).

BTW, this is not happening with an IMAP account I also use with TBird. Copies of messages I sent continue to be automatically saved to that account's Sent folder (as usual).

After researching this problem for several hours today, I've found that it's not an uncommon issue. The general advice is to navigate to Tools > Account Settings > Copies & Folders, check the Place a copy in, select Other, then point to the Sent folder of the affected account. (Alternatively, a copy can be requested to be placed in the Sent folder under Local Folders, which is actually what I've had set for many years of using TBird).

I tried sending multiple test emails to no avail. Nothing solved the problem of no copies in SENT. Despite that, every time I sent a new email, my Sent folder message count showed the addition of one more message, but no message appeared. Right now my Sent folder says there are 14 messages there, but none actually appear. The folder is empty.

I then tried several other alternative suggestions from Mozilla and other websites. Nothing works. Copies of emails I send are being saved to my Sent folder on Gmail webmail. Just not in Thunderbird.

I also tried the REPAIR option for my Sent folder. No effect. Shut down the program, re-started it, etc.

I verified that I had set TBird as an exclusion in Windows Security.

As a last resort (since this is a very troublesome problem!) I created a new "Copies" folder under my Local Folders and set the "Place a copy in" that new folder instead of into Sent. That did actually work. Copies of emails I sent after that did show up in that new "Copies" folder.

I would appreciate any assistance you can give, as I suspect my TBird Sent folder has somehow become suddenly corrupted. If so, can you suggest how to proceed. Thanks very much!

Hello !

I've been looking for some ways to import GMail takeout exported mails files that use MBox format. Googling I found some extension to do it, named "ImportExportTools NG". I've tested and it seems to have some issues : for example, after importing some MBOX files, the mails counts doesn't match GMail's values. I have not spent time to diagnose it yet...

I've also tried to simply put my MBOX files in my TB local folders and it seems to work.

Please, could someone confirm that this last trivial way actually works, and thus there's no need to any extension or tool ?

Thanks for your help.

Regards.

I moved Thunderbird to a new PC recently. Thunderbird runs fine. I want to backup the profile folder. Windows file explorer does not see the profile ; yes I have set hidden files to view. The only profile it sees is the one I copied over from old PC that has not been modified (see image). In Thunderbird, I go to troubleshoot information, Profile folder, open folder, I get Location is not available error (see image). I go to about:profiles, open folder (any, see image), get same error. Profile manager does not see the old profile from old PC. How do I make Windows and Thunderbird see and open the profile folder Thunderbird is using successfully? Thank you

Hello all I just started my thunderbird after years of outlook. And I have donated money I hope this helps to keep this alive. With recent 2FA changes I have had to move here. it is years of old emails and for now I am getting them to review later.

But everyone seems nice here.

When I am downloading I notice limits on number of messages in one mailbox in Thunderbird. One mailbox is everything inside one email username right?

Sometimes it stops at 10, 000 Is the limit based on thunderbird or the email server I am getting my emails from ???

Thank you for anticipated help!

I am getting the Mozilla Thunderbird Email wants to access your Google Account all the time while using TBM, I have removed the gmail account and the pop up does not show, so I know it is for the email account just removed. I re-add the email address and enter the email address and password and let it find the config itself. Click Done, and get the Mozilla Thunderbird Email wants to access your Google Account again, then click Allow and get the Authentication failure while connecting to server imap.gmail.com. message in the bottom left of my desktop. How can i get gmail to work again please.

I recently upgraded to version 60 from (I think) 58 something. Now there is no HTML tab above the body of the email and I can find no way to get into the HTML. Why has this gone away or, if it hasn't gone away, how do I get to it?

Email from a trusted address over past decade is suddenly going to Junk as of today. Cannot see how to whitelist the Sender, and googling the question tells me to go to Tools>Options, however Options does not show in the Tools menu.

There is no option for message headers under View. How can I see email message headers in Thunderbird?

I Googled how to do this but they all say there is an option in the main menu under View. Maybe at some point there was, but not now. So how can I see the email headers?
