I have imported a public key in my openpgp key-management/ In my settings of the end -to-end keys: preference of key technology: choose auto the key technology by the available keys. I have read openpgp standard supports inline en s/mime encryption but what is used by thunderbird when I choose openpgp as key encryption when i type/send an email (w/o attachment by myself). I ask it because my correspondent only decrypts inline encryption.

I am having issues with Thunderbird not retaining my email server and passwords. Each time I want to send an email, it prompts me for the password and then tells me that the email address and server don't match. I have tried numerous times to correct this, but it doesn't hold the information. It also switches the server info between accounts. I have 3 different email account and sometimes only one works correctly

Hello

I have been using Thunderbird as my email service and not had this before. Yesterday, I had to change my password for emails with BT. I changed it on Thunderbird too but now I am receiving emails OK on Thunderbird it is refusing to send any for me and shows the above message. I can send OK from my web based BT email but prefer Thunderbird.

I haven't a clue what I need to do to solve this.

Can you please help? Please tell me is very simple steps I'm not very computer savvy.

Thank you

But I have tried looking online to check, are the attachments to the email also encrypted?

I have upgraded to the Microsoft 365 Business Professional email service which should allow me to continue with Thunderbird, now that basic authentication is no longer supported.

I have enabled Exchange settings. Also, POP/IMAP and SMTP are authorized in the MS 365 account, and those setting are correct in T-Bird. From within Thunderbird, a login screen for the MS 365 email account is generated when T-Bird attempts to log in to the server, but the log in just takes me to the server page in the browser.

This help article https://support.mozilla.org/en-US/kb/microsoft-oauth-authentication-and-thunderbird-202 advises that Thunderbird may need to be authorized. I followed the link, but was not able to make it work.

Given the following provided link, what is to be used for {tenant-id} ? https://login.microsoftonline.com/{tenant-id}/adminconsent?client_id=9e5f94bc-e8a4-4e73-b8be-63364c29d753

Any other advice? Thank you very much!

Network Solutions upgraded their email, and I multiply-checked all my settings in Thunderbird (102.3.2) and can retrieve mail but the outgoing mail hangs and time out with an error. I just discovered it's not my settings, but there's no password listed for the default outgoing SMTP server (my own domain). (I have 2 email accounts, and listed in the "Saved Passwords" are 2 passwords for incoming IMAP plus one the other account outgoing SMTP, 3 total.)

Is there any way to add a password without deleting the default server and then adding it back in, or some other solution?

Thanks

Hi,

I used to use Thunderbird to access Gmail, Yahoo mail and normal email account (all POP3).

I have updated (not reinstall) Thunderbird to the latest version since Gmail disabled non secure apps access.

I have changed the Authentication to OAuth by follow the instruction from your page, but the system keep asking me to login (I have grant access in Gmail).

This happens not only Gmail as well as my Yahoo mail and normal POP3 account. I am sure the password is correct and still cannot get my emails from all of my accounts.

I also notice the token/password has not been saved to the system in Saved Password session. ( I have tried to run as administrator but still doesn't work.)

What have I missed? Can still using POP3 method to get email if problem solved?

My current system is Win7 with Thunderbird 32bit installed.

Thanks!!

Hello, I received a Yubikey 5 and all is working fine using GPG with it, except integration with Thunderbird on Windows.

I followed this guide: https://wiki.mozilla.org/Thunderbird:OpenPGP:Smartcards including 64 windows section

I was able to successfully send mail to myself, but then thunderbird failed at decrypting this message: Thunderbird is indicating that key is not available and I see no prompt from gpg-agent. Key is correctly declared as GPG external.

If I try to decrypt tis email by storing it on file and using gpg in command line, it works fine: agent is asking for Yubikey PIN and gpg is decrypting the message. But this is an awful workaround, not user friendly at all.

I also did sanity check by sending to myself a message encrypted with a key generated by Thunderbird: all is working fine, the message is decrypted within Thunderbird.

=> How do you make Thunderbird decrypt message encrypted with key stored in Yubikey? How do you make the gpg-agent called by thunderbird?

I received the following from my e-mail provider, and as a total dumbo about this, want to ask if I need to do anything about this in Thunderbird (Linux). As far as I can see, my e-mail account in Thunderbird is set to POP3, encrypted using SSL/TLs, normal password - can anyone tell me if this is OK - Thanks.

Quote: "We are contacting you because one or more of your devices or programs uses the TLS 1.0 and/or TLS 1.1 encryption protocols to connect to our mail.com email servers, or is using an unencrypted connection. This involves either access via SMTP (sending emails) or retrieval via POP3/IMAP (receiving emails).

Unfortunately, the TLS 1.0 and TLS 1.1 encryption protocols are outdated and no longer meet current security standards. To protect your email communications, soon we will no longer allow access to our mail.com servers with these outdated protocols. Unencrypted access will also no longer be possible.

After the protocols have been deactivated, the transfer of emails between your affected device or program and our mail.com servers will no longer work; i.e. no emails will be transmitted to or from your mail.com email account using TLS 1.0 and TLS 1.1. Furthermore, unencrypted SMTP/IMAP/POP3 connections will no longer function. In other words, as of Oct. 5, 2022, it will only be possible to connect if TLS 1.2 or TLS 1.3 encryption is in place."

Hello,

I am using the latest stable release of Thunderbird client on Windows 11 and just today it's been asking me multiple times for a password to my Outlook account. I have kept adding a one time app password through the official Microsoft website under account management but it's been asking a few times that it needs a password.

Do you know if there's been any outages to the Microsoft servers or what this issue could be related to? Is there a way I can send any logs directly to you that might help find the issue?

Thank you for your time.

Hello,

All of a sudden, this morning, my Thunderbird (102.12.0) will not sync my Office365 account's inbox via IMAP. I get the error message that

The current command did not succeed. The mail server for account [my university account] responded: User is authenticated but not connected.

A couple of seconds later, the above message is replaced by:

Server outlook.office365.com has disconnected. The server may have gone down or there may be a network problem.

The problem occurs on my laptop and on my desktop. I am sure all my settings are correct. I have read the entire thread here: https://answers.microsoft.com/en-us/outlook_com/forum/all/thunderbird-imap-responded-user-is-authenticated/062a82f6-e678-4462-88b7-dd6cc318386f

I have disabled IPV6 as instructed in the preferred answer: advanced config > network.dns.disableIPv6 = true.

I have also added network.dns.ipv4OnlyDomains = office365.com (I also tried outlook.office365.com).

I am using Kaspersky One antivirus. When I installed it, I had to add Outlook in the trusted addresses, as it wouldn't let me send email, but after I did, Thunderbird was again working as expected (this was two months ago). I am adding this detail just in case it is somehow relevant.

I am not sure when Thunderbird updated to 102.12.0 or if this is in any way related to the problem.

Meanwhile, I can sync incoming mail in my Gmail app on Android. I saw that the IMAP setting there uses port 443 instead of 993. When I tried setting 443 in Thunderbird, it simply took too long to connect to the server and timed out.

I don't know what else to try. Hopefully, you can think of a solution.

After update to 102, TB is asking for a PW when starting in normal mode. -> PW-vault is empty When starting in safe-mode everything is working well. (PW-vault is not empty)

I tried to make a new profile. Then it worked, but only until next update (102.0.1).

This happend also after update to 102.0.2 and 102.0.3. :(

Now I tried to copy a not working profile folder from mounted NAS-drive to local drive. -> Profile on mounted device is working only in safe-mode -> Profile on local device is working well in normal mode

For me it looks like, TB is not able to read (decrypt?) stored PW from mounted devices in normal mode. (But it works well in safe-mode).

I have been getting this message since January and am starting to be concerned

Secure connection failed start.thunderbird.net uses an invalid security certificate. The certificate is not trusted because the issuer certificate has expired. Error code: <a id="errorCode" title="SEC_ERROR_EXPIRED_ISSUER_CERTIFICATE">SEC_ERROR_EXPIRED_ISSUER_CERTIFICATE</a>

  This could be a problem with the server's configuration, or it could be someone trying to impersonate the server.
  If you have connected to this server successfully in the past, the error may be temporary, and you can try again later.

Or you can add an exception… When I click on add an exception nothing happens. I tried closing Thunderbird, deleting my cert8.db file and restarting Thunderbird - no change - same message. I am running Windows 10, Thunderbird version 45.8.0

Help, please ! Thanks, Sarah

ThunderBird stopped being able to pick up email from our pop3 server.

The Error console shows:

mailnews.pop3.1: SecurityError: a SecurityCertificate error occurred Pop3Client.jsm:336:18

This doesn't give me a hint as to the problem is with the security certificate. It hasn't changed recently and worked yesterday.

The cert is self-signed and expires in a few days. Previously (not recently) I had to do a variety of things to make Thunderbird happy with it.
