Gmail is going to require OAuth 2.0 sign-in SFAIK, that means I will no longer be able to access gmail with Thunderbird. Are there plans for Thunderbird to meet the OAuth 2.0 requirement?

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!

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?

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

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.

Hi

I'm trying to set up another email account but the Confirm Security Exception dialogue is preventing it. The exception is already stored but still keeps asking and when I reconfirm the dialogue flashes off/on and doesn't not disappear preventing the set up of the account. I have other emails from the same host and have not had this issue before. Anything I maybe doing wrong or bug? I've added a screenshot.

Many thanks Alan

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.

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!!

Outgoing email includes the user-agent header. I would like to disable or modify the string for better security.

User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:91.0) Gecko/20100101 Thunderbird/91.8.0

Thanks...

I've been using Outlook Express (from XP) for years, even into the Windows 10 era with a patched version of XP. Since GMail will no longer support it after May 2022 I decided to migrate to Thunderbird Portable.

Since 91.8.1 doesn't import from Outlook Express, I first used Thunderbird Portable 52.9.1 x86 (last version that supports XP) to import mails, accounts and whatever else it imports. I then set up a Primary Password, and painstakingly manually added all rules from Outlook Express to Thunderbird's "filters". After everything was up and running, I upgraded to Thunderbird Portable 91.8.1 x86.

For some reason, when I try to login to any GMail account, after the login, pass, allow Thunderbird as email client, a popup window appears asking me to "Change Password", but whatever password I put, it always says "Unable to change password". If I go to "Privacy & Security", "Use a Primary Password" is disabled, and if I check it, it asks me to enter and re-enter a new password, but it also says "Unable to change Primary Password".

II tried both commands listed in the link below, both seem to work by pressing the Reset button, but the error console seems to output a uncaught exception. https://support.mozilla.org/en-US/kb/protect-your-thunderbird-passwords-master-password#w_resetting-your-master-password-if-you-have-forgotten-it

Any more suggestions?

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.

I have been using Thunderbird for several years for my GMail accounts, and have always preferred to download my messages using the POP and SMTP protocols, rather than use the IMAP protocol which leaves them all on the web. Google now inform me that "To help keep your account secure, Google will no longer support the use of third-party apps or devices which ask you to sign in to your Google Account using only your username and password. Instead, you’ll need to sign in using Sign in with Google or other more secure technologies, like OAuth 2.0. What do you need to do? Email software, like Outlook 2016 or earlier, has less secure access to your Gmail. Switch to Office 365, Outlook 2019 or newer, or any other email software where you can sign in using Sign in with Google." These changes are due to take effect from May 30th. How can I prepare for them and still use the POP and SMTP protocols after that date? Is OAuth 2.0 appropriate?

Hi,

I have my Thunderbird 91.8.0 (64-bit) (Fedora 35) setup to use PGP aliases- This worked well quite some weeks. Since a short time (like one week or so) I do encounter a problem:

First when trying to use an alias, thunderbird told me there was no key for encrytion found. So I checked my settings and the profile directory for the .json file containing the alias rules. It was there as expected. Trying to fix the problem I did copy the file, rename it an change the mail.openpgp.alias_rules_file value to the new name. Now it would find the file again but tell me the corresponding public PGP key is missing.

I checked using the Thunderbird integrated OpenPGP Key Manager and indeed the public key for the alias was missing. So I did try to import this key again after downloading and saving it (from https://keys.openpgp.org/) but this always throws an error which doesn't tell a reason (see picture).

Btw: I also checked the pubring.gpg file with grep and it seems like the desired key is in there (I'm not very experienced in using grep but the output was somethig like "found occurence in binary file" for: grep XXXX (name of the owner of the key) ~/.thunderbird/NNNNxrez.default-release/pubring.gpg)

Does anyone know what the problem is or how to fix it? Maybe there is just a format problem when trying to import from https://keys.openpgp.org/ https://keys.openpgp.org/] ? Cause I did test it with another key from there with the same result...

Would appreciate any help or tip what to try!

Cheers!

I'm using Thunderbird for gmail in IMAP mode. In my IMAP folder, I have a Junk subfolder, and in my Gmail subfolder I have a Spam subfolder. What is the difference between these? Does Gmail determine Spam, and Thunderbird determine Junk? Are BOTH Spam and Junk used for the Thunderbird adaptive junk filter log?

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've appreciated using Thunderbird for an ad-free Hotmail experience for quite some time. I've changed my Hotmail password every few weeks lately and Thunderbird worked fine when I entered the new password at the prompt when Thunderbird started.

Just now however, I needed to get into my Microsoft account that uses the same password as my Hotmail account. My login to Microsoft failed. Trying to understand why, I looked in Thunderbird at the saved password for Hotmail's server:

oauth://login.microsoftonline.com (https://outlook.office.com/IMAP.AccessAsUser.All

https://outlook.office.com/POP.AccessAsUser.All 
https://outlook.office.com/SMTP.Send offline_access)

The saved password was a 464 character long ASCII string totally irrelevant to the password I'd selected for Hotmail and Microsoft.

I went through the password change process for Hotmail, was then able to get into my Microsoft account and restarted Thunderbird. As usual, Thunderbird asked for the new password. I entered it and was then able to receive new mail from the Hotmail server in Thunderbird. However, again, the saved password in Thunderbird for Hotmail was not the password I'd entered.

Next, I deleted the saved passwords in Thunderbird, restarted it and this time it prompted me to be sure I'd downloaded it from a reliable source. I've never seen that prompt before. It came with my Linux Mint installation, so I thought it would be safe, but again there's an irrelevant password saved for my Hotmail account.

It's like it eventually changes my password for Hotmail and Microsoft since I can get mail through Thunderbird with the odd password it saves, but if I use what should be my password for Hotmail or my Microsoft account via a web page interface, the password doesn't work.

I'll have to stop using Thunderbird if this continues.

Hello!

After upgrading from a very old (but perfectly working) version of Thunderbird (24.3.0 on Windows 7) to 91.8.1 (on the same Windows 7 system), Thunderbird can no longer remember my passwords.

Apart from this everything in the new version works. Emails are retrieved fine when I enter the passwords manually.

Symptoms:

• always asks me for my passwords, even when I have checked the "Use Password Manager to remember this password" checkbox.
• no stored passwords show up in "Saved Passwords ..."
• When I try to set a primary password (I did not use one so far), I get an error "Unable to change Primary Password".

What I tried after searching for solutions:

• Remove files cert*.db and key*.db from my profile. Does not make any difference.

best regards

Edwin

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
