Thunderbird Support Forum

Hello.

I read that thunderbird works with Microsoft 365 and modern authentication. I tested with Microsoft 365 accounts and it worked fine. The problems come with an accounting of Microsoft 365 operated by 21vianet service.

I configured according to https://support.mozilla.org/en-US/kb/microsoft-oauth-authentication-and-thunderbird-202 with the IMAP and SMTP settings from https://support.microsoft.com/en-us/office/settings-for-pop-and-imap-access-for-microsoft-365-operated-by-21vianet-ca51235d-afc5-4d7d-843c-3616a37d5771

It complaints "The IMAP server partner.outlook.cn does not support the selected authentication method. Please change the 'Authentication method' in the 'Account Settings | Server settings.'"

In SMTP settings there is no option to configure OAuth2

I installed the Thunderbird software on (2) devices to replace the Windows Mail product. On the first device (Windows 11 laptop) I was able to add all (3) personal email accounts needed (1 Spectrum and 2 Gmail). On the second computer (Windows 11 MS Surface) i was only able to install (1) Gmail account and the Spectrum account. The second Gmail account gives an error when it tries to verify the account with Google giving the error as follows.

400 that is an error. The server cannot process the request because it's malformed. It should not be retried. That's all we know.

Since the settings on both computers are the same for the account and both Gmail accounts work on one computer this doesn't make sense to me. Any suggestions would be helpful.

Is it possible to install TB (or at least the profiles) onto an external SSD (i.e., not the C: drive)? If so, how?

Note: this is not about migration/backup/recovery of profiles.

Windows 11 is consuming nearly all of the C: drive. I badly need to get TB (and Firerfox) onto my E: drive. I further note that the installer gives no options whatsoever as to the destination drive.

I've read everything I could find here and all of that is about using an external drive as a backup. Most of the other help I've found on the web is clearly outdated.

Thanks. jt

Trying to use my old profile on a fresh install.

After trying a few things I ended up with an error that the profile couldn't be loaded or was inaccessible.

So I did the following:

1) started the profile manager 2) removed all profiles 3) created a new profile 4) changed the name of the folder in the file system 5) copied my old profile folder to the same spot with the same name that the profile manager gave it

When I started thunderbird, I was just expecting it to load with my old profile.

Instead, I got the Account Setup screen.

I don't want to setup my email account, as I'm worried it will start downloading all my emails, and store them in who knows what profile. I could not see a way to start Thunderbird without it successfully connecting to an email server in this setup process.

Any suggestions for just getting mozilla to start and load my old profile please?

I'm a long-term Outlook user looking to move from Outlook 2013 (now unsupported by MS) to Thunderbird. I've looked at all Mozilla documentation, as well as Google Search and can't seem to find a full understanding of the migration process. I have tried to manually do so using the Tools>Import in Thunderbird, but I continually get an error message that "the current mail client cannot fulfill the messaging request". (Yes, Outlook is my default mail client).

Also, I'm now seeing the following on my Thunderbird home page: Secure connection failed live.mozillamessaging.com uses an invalid security certificate. The certificate is not trusted because the issuer certificate is unknown.

Can anyone help an Outlook refugee? Thanks in advance.

I had to purchase a new computer and the set-up did not transfer my account of mozilla thunderbird files and e-mails. I downloaded the mz app and followed the instructions to Set Up Your Email Address and the Configuration was found in Mozilla ISP database. So when I selected Done, the prompt read: "Could not get OAuth2 details for hostname=imap.comcast.net." What do I need to do to retrieve my files and e-mails in the mozilla thunderbird website and transfer them to my new computer? Thanks

Cox dumped all of COX email onto Yahoo. I have used Thunderbird for years but now I cannot set up my Yahoo account in Thunderbird. We were allowed to keep the COX address. Possibly the @cox.net is confusing the software. Are there instructions for doing this? Thanks, Alex stantona@cox.net

Dell Inspiron came with OS on a small C: & data on a massive D:. I assumed the Dell-guided migration took care of moving everything necessary to D: ...NOT!!! When C: filled up with data, I was trying to move Thunderbird TB) data to D: & somehow deleted thunderbird.exe. I realized my error when the systray icons for TB, Firefox, & Microsoft Edge responded "Can't open this item." I then accidentally clicked "Y" to "...Delete this item"? When I went to download a new copy of TB, it presented the new user screen. From previous research, I found my profile file and copied it to both C: & D: with a new name to have extra copies. So I have 3 requests 1) What is the safest method for getting TB back? 2) Once that is done, how do I get thunderbird to maintain everything I need on the D: drive? 3) Firefox now works, but all my bookmarks, extensions, etc. are now gone. If that issue is appropriately part of the solution for the above requests, please help me with that as well. I will appreciate your help! Ken Cawthorne

I've been using Thunderbird for over 25 years and have always loved it. Recently, my emails are all messed up. When I receive, there are 3 sections: the top shows the From, Subject, and Date as it is supposed to do. The middle section is the problem: it shows all kinds of stuff I'm not interested in, such as Message ID, In reply to, References, User agent, X-Authority-Analysis (which is full of nonsense), and below that all kinds of stuff that makes no sense at all (not English). And the 3rd section is where I respond. How do I get rid of that middle section? All I want is what the writer wrote and what I should reply to. That's it. What happened to T-Bird?

Here is a very tiny portion of that middle, illegible section: <v-dpfdcc_lllpljofc_fkjkddff_fkjkddff_a@bounce.e.traindemocrats.org> from p-impin005.msg.pkvw.co.charter.net ([47.43.26.146]) by p-mtain015.msg.pkvw.co.charter.net (InterMail vM.9.01.00.037.1 201-2473-137-122-172) with ESMTP id <20240607200201.KKSQ3703.p-mtain015.msg.pkvw.co.charter.net@p-impin005.msg.pkvw.co.charter.net> for <advenosa@cinci.rr.com>; Fri, 7 Jun 2024 20:02:01 +0000.

My name is Al Venosa, and my email address is advenosa@cinci.rr.com. Thank you.

I have two email accounts on my website that is hosted by Hostpapa. Years ago I successfully set up email for both accounts in Thunderbird. Recently (probably after an upgrade) one of the accounts stopped working and I get a timed out message when fetching email messages. After checking the server settings and password were correct the problem was not fixed, so I deleted the account and tried to re-add it in Thunderbird. The incoming and outgoing server settings are correct as is the password. I know the password is correct because I can successfully login to the account using webmail. I received the following error message on the "Setup your Existing Email Address" page. The message appears above the "Checking Password" button.

"Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) [nsiMsgAccountManager.createIncomingServer]

The password on the account is 16 characters long and contains the following special characters: "!#"

I am using Thunderbird version 115.11.1 (64-bit) - on the esr channel

Can anyone help?

The last time I upgraded my long time Thunderbird account, everything crashed and I lost all my contacts and bookmarks! Why should I ever upgrade again? I reported this a year ago or so and never got any response or help.
