Unable to send or receive emails, via several gmail accounts. Thunderbird 128.5.2esr (64-bit); Windows 11 Home, 23H2 Have used Thunderbird and Gmail together for over a decade - various glitches along the way, but nothing for which some solution was not found, at least up until now.

1) On Dec 31, 2024, received an error msg "Unable to write the email to the mailbox. Make sure the file system allows you write privileges, and you have enough disk space to copy the mailbox." Thunderbird Inbox for that gmail account had grown bloated - in part because Message Filtering had stopped working (another issue...): moved / deleted a bunch of emails, and was able to receive new ones.

2) On Jan 1, 2025, ALL gmail accounts stopped receiving messages, initially with error of "Connection to server.pop.gmail was reset." As of today (Jan 4), all accounts are still non-functioning, but T'bird has given up even throwing up an error when attempting to retrieve messages. Attempting to Send a msg results in: "An error occurred while sending mail: Outgoing server (SMTP) error. The server responded: Cannot connect to SMTP server 172.253.113.109 (172.253.113.109:587), connect error 10060."

3) Running Nordvpn and Norton security suite. Have defeated both, to no avail. (With close / reopen T'bird; Reboot system thrown in for good measure.) Note: Have ran both of those apps, with Thunderbird, literally for years without any known problems due to the combination.

4) Confirmed that the Gmail / Thunderbird settings agreed with Gmail recommendations (and each other).

5) Removed permission for one of the accounts from google's site, hoping T'bird would prompt for new one: no go. Then TRIED to Remove the Thunderbird-stored Account Password for that account, but was stymied by a "Windows Security" dialog asking for an Account PIN: Do not recall ever creating such a beast for Thunderbird, and none of the possible stored Passwords proved acceptable. Also wonder why a Windows Security dialog is being tossed up from within T'bird.) (The dialog box offers up a "try another way" option, but that simply calls up a prompt for Username / Password: NO COMBINATION of those worked. Note that ALL such combos are stored in Bitwarden and eWallet, and work for those same accounts in other access situations.)

Obviously a frustrating situation. Am posting this in the hope that someone will be able to provide suggestions. In the meantime, have decided that it may be wise to look for alternative email solutions, although that is definitely a Non-Optimal approach: am a fan of Copernic Desktop Search, which only works with either Thunderbird or Outlook, and I have much preferred T'bird over the years.

thunderbird affiche :' Échec de la connexion depuis le serveur imap.orange.fr '. On me demande un mot de passe. comment remédier ?

Whenever I click on a github link specifically in an email, thunderbird stops responding and doesn't seem to ever recover. Restarting my machine worked for a short while before the problem returned. I've also tried deleting a lot of my mail from github, and deleting all my "msf" files, but it doesn't resolve the issue. I've used thunderbird for this for a long while, so this is something very recent, possibly caused by the previous update.

While thunderbird hangs it doesn't appear to be using any abnormal amounts of CPU, so it's not spinning on some heavy task.

I'm on version 128.5.2esr (64-bit), Fedora 41. The browser (which is my default browser) is firefox.

Thanks for any help you can provide, I'd really like to be able to keep using Thunderbird.

I use Thunderbird to download messages from gmail.com. Thunderbird has begun to download and immediately drop some of the messages. I see the downloaded heading and then it disappears from the inbox. Some dropped messages are from sources that I regularly have received from. Because I see the message heading and then it is gone, I believe the problem lies with Thunderbird. Perhaps a setting needs to be changed? How can I fix this? Thanks, John H

This all started when I cancelled Xfinity and went to Frontier Internet. I had previously used Thunderbird for 8 years through Xfinity with no problems. I have contacted Xfinity and Frontier and both have told me it is a problem with a Thunderbird setting.

Sending of the message failed. An error occured while sending mail: Outgoing mail server (smtp) error. The server responded: resomta-c2p-555920.sys.comcast.net resonta-c2p-555920 sys.comcast.net. Excesive failed authentication. ESMTP server temporarily not available.

Using Thunderbird 128.5.0esr (64-bit) on 128.5.0esr (64-bit). In calendar view, I see all my appointments with the background colour of the calendar they are in (see attached). In my inbox view, I have the Events tab open at the right. All day events have the background colour of the appropriate calendar, but ones with timings have a dot. (see attached). How do I make ALL calendar events have the background colour of the associated calendar in the mail events tab??

I have just installed thunderbird and am in the process of transfering .eml files into various folders that I have set up. Everything seems to be working fine except that sometimes a file is transferred and it is unnecessary or old or irrelevant to me. When I try to delete the file it refuses to delete - stays in the message list. It also will not respond to a move or any other command...it's like "frozen". How do I get rid of (or perform any action on) a file like this? And, why is this happening? Thanks!

After an update of TB and extensive cleanup, I still cannot move some but not all incoming messages to local folders.

This problem has existed for a long time.

I have purged all .msf files to no avail.

Can't seem to get thunderbird to connect to my xfinity (comcast.net) email... tried full reinstalls, changing the password, and all the steps in this: https://support.mozilla.org/en-US/questions/1437228

As well as trying "normal password" instead of OAuth2. The OAuth2 option does not seem to generate a pop-up to authorize that way. Using other 3rd party and logging in via browser also work.

Does thunderbird need to update something to fix the issue? Its been only a few weeks now for me that this was an issue.

Suddenly today, I cannot send or receive email messages via Thunderbird program, and must go to the internet to see my messages. I receive the notice "Login to server smpt.comcast.net with username failed". I did update my Comcast password today. Thank you

I have been using Thunderbird for decades. I now use a windows 11 PC Recently, it have been taking a very long time to connect to my POP3 email server (am I using the right terminology?)--which is att.net. Then, about a week ago, it stopped connecting entirely. I tried everything, then as a last resort, I saved all my profile data (I know how to do this) on to an external drive, uninstalled Thunderbird from the PC, deleted all the files, both local and roaming, and then downloaded and installed it again, just as if I was a first time user. Still would not connect. I can still receive emails on my ipad, phone, and on yahoo.com on a browser, so I know that my password is correct. Thoughts?

Hi. Four days ago, Thunderbird ceased loading for no apparent reason. Can I either repair or reinstall Thunderbird without losing my stored messages and folders? Thanks.

I want to get a new PC. My emails come in through GMail and are then transferred to Thunderbird. Once transferred they are deleted from GMail. I have several hundred emails in the Inbox of Thunderbird (one year I must delete the majority!) Also some in folders off the Inbox. How do I transfer them over to a new PC? Some are important that I wouldn't want to lose - eg my wife's name!!!!!

Any help would be greatefully received.

The latest version of Thunderbird does not seem to have a way to turn off automatic sending of public key and digital signature even when sending *unencrypted* messages. (Prior to 2020, I'm informed there was a way to uncheck "sign all outgoing messages" which I think might have addressed this).

Now letting everyone know my public key would be desirable, except bone-headed email systems -- such as Yahoo Mail -- seem to be more likely to consign my emails to the spam bin with these attachments to spam as being considered suspicious!

How can I have OpenPGP keys installed on an email account, set to not encrypt new messages, and NOT automatically send public key and signature attachments?

Perhaps I should mention that I am using the latest Thunderbird on Windows 11, via Proton Bridge, through the extremely infuriating Proton Mail service.

Thanks, Michael

Hi, The emails I get regularly from Rumble from the people I follow are not showing the picture content I normally see in the mail body. It has been replaced with a hyperlink that says 'thumbnail'. I have the View -> Message Body set to 'Original HTML'. When I change it to 'Simple HTML' it does not solve the problem. I have attached a screenshot of the email.

Thanks!
