After update to above Beta I keep getting mailbox filter errors on Default account, occurs at start-up & when some new messages arrive that are sent into the filters . See screenshot attached. Many Thanks

Hi,

I have a strange problem with Thunderbird (currently 91.8.1 on Linux, but have this problem for a while). Initially (i.e. after each reboot) Thunderbird works normally but at some point when I start Thunderbird all I can see in the folders list are one entry for each account (see attached screenshot). I can still edit account details. But the only way to make it work again is to reboot my system. Just logging out and in is not sufficient. I tried to start Thunderbird in safe mote or to get some log details but nothing helped or got me a step further.

Today I experienced something new. I worked with Thunderbird and didn't close it (and also didn't suspend or hibernate the system). At some point when I wanted to visit the sent-item-folder I got an error message (unfortunately I didn't make a screenshot) that the folder couldn't be loaded. Then I couldn't open any folder. After restarting Thunderbird I had the problem of above.

Hope someone has an idea how to fix this.

Somewhen before or with 91.2.1, the default action when opening an existing email became "Edit draft message." (W10 19043, synching to GMail) That setting is nonintuitive and just wrong. A default should NEVER be an action that commits to an irreversable behavior path. Please fix.

This extremely bad design "feature" has apparently been around quite a while and generates exactly the problems returned by a search here on "delete attachments Thunderbird." I first noticed the behavior just about the time GMail introduced two-factor authentication. Maybe no connection there, but ...

I can not get thunderbird to bring over email for 6 days now I get the following error everytime. (Sending of password for user .........................@verizon.net did not succeed. Mail server pop.verizon.net responded: [SYS/TEMP] Server error - Please try again later.) I have tried creating a new password on the server account and restarting thunderbird with the new password . Did not help. Any Suggestions?

hi, I follow some suggestions as

https://support.mozilla.org/en-US/questions/1309622

and I try to delete mimeTypes.rdf and handlers.json but Thunrderbid continues to use chromium to open https links.

Can you help me?

Version 91.7.0 only allows me to send mail from one e-mail address, as all the smtp settings are now the same. Previously, each address could have different settings, which my e-mail provider requires.

After updating Thunderbird to the new version 91.9.1, most of my email messages disappeared.

An error message was displayed after updating to the new version. Thunderbird restart chashed and I started the program again, just to noticed that the messages were not anymore in the folders.

How can I recover my messages?

Hi!

I often send an email to 140 recipients via SMTP. Until recently it took 2-3 seconds. Now it takes about 2 minutes. My web-hosting company Simply.com is very insistent that their server is not the problem. I use TB 91.7.0 (64-bit) on Ubuntu 20.04.4 LTS. I am not sure whether TB updated itself when the problem started. Any help would be appreciated.

I am using v. 91.9.1 of Thunderbird e-mail

I have been running 4 e-mail addresses, all with BT.

This last week 2 of those addresses have stopped sending outward messages although I haven't changed anything in Thunderbird or BT.

The other 2 addresses work for both in & outgoing mail.

On the failed outgoing mail I get the following message:- "Sending of the message failed. Unable to authenticate to Outgoing server (SMTP) mail.btinternet.com. Please check the password and verify the 'Authentication method' in 'Account Settings | Outgoing server (SMTP)'." BT says they can't help. The problem is with Thunderbird??

Any ideas ? Regards David Bates

I'm a long time user of Linux Mint. Now on 20.3 and Cinnamon desktop. Also a long time user of Thunderbird. Now in version 91.8.1 Always used the "allow insecure apps" in my gmail account settings and used normal password stored in Thunderbird. Google urges to change the authentication method to oAuth2. Tried everything to no avail. Always "authentication fails when connecting to imap.gmail.com" Cleared all cookies, allowed them, deleted all saved passwords, followed all published advise I could find, and nothing. Then I made a brand new profile pointing to an empty dir and entered my gmail address and checked everything. Same result. In despair I installed Evolution and all run fine at the first try. Should I really give up on Thunderbird? Thanks in advance for any help!

Hi, I have an existing installation of Thunderbird 91.9.1 on my linux system. I have a gmail, outlook and web.de mail each running via this installation (IMAP). My new workmail is hosted by 1&1(ionos). I can log in via web interface. Autoconfig finds the configuration that is (according to their help articles) the correct one to access the Mail via IMAP. Incoming: imap.1und1.de SSL/TLS 993 Outgoing: smtp.1und1.de STARTTLS 587 normal Password Username is my full email address. There have been no typos. I checked 5x, copy pasted, rechecked. Pasted it into the web interface login, and thunderbird before clicking go on each -> tb - no, web - yes domain is talsen.team

I would appreciate some pointers to get this fixed. And yes i did read prior questions regarding this error. It did not help in my case.

I have lost my IMAP and SMTP connections between Thunderbird v91.9.0 on Windows 10 and two Gmail accounts. One is a standard @gmail.com account and the other is an @my_domain account on Google Workspace. The experience is (almost) the same on both.

Any help would be greatly appreciated.

When I try to read IMAP mail through Thunderbird, I'm presented with a pop-up (apparently from Google) to log into the gmail account with the email address pre-populated in the "Enter your email" field. Curiously, the email address for the Google Workspace account is broken into two parts with the user name left justified in the field, the @my_domain right justified and a gap between them. This is not true for the standard @gmail.com account, where the field is prepopulated with a left justified username@gmail.com. I click the "Next" button and an "Enter your password pop-up (apparently from Google) appears, into which I enter the password and click "Next".

Then I see a pop-up (apparently from Google) which says "Mozilla Thunderbird Email wants to access your Google Account", with "Allow" and "Cancel" buttons. I click "Allow" and often (but not always) see a small pop-up (apparently from Thunderbird) which says "Authentication failure while connecting to server imap.gmail.com".

The experience on the sending side through SMTP is similar. Upon clicking "Send" in Thunderbird, I'm presented with the same sequence of pop-ups (apparently from Google) to enter Google user name, password and permission to allow Thunderbird to access my email. Then there is a "sending message" pop-up (apparently from Thunderbird) which never completes.

Here are what I think are the relevant Thunderbird settings --

 Thunderbird settings for user@my_domain.com

   Accept third-party cookies: Always

Here are what I think is the relevant Gmail setting --

  IMAP is enabled

I have Thunderbird installed on two computers.

On one of the computers, emails being held in my inbox are being automatically removed after two weeks (this is not a desirable action, I am loosing important emails), but on the other computer that is configured exactly the same, emails remain in the inbox indefinitely (which is desired).

Both computers are POP and both configured to run the same email account and appear to have all of the same configurations and settings. I saw someone had posted the same problem a while ago and the reply indicated it may be that the ISP or email provider has their settings set to delete emails as per the two week window, but as I can assure you this is not the case, it is a configuration issue with one of the Thunderbird installations, otherwise both of my computers would be deleting the emails while that is not the case.

Thanks,

Hi, I updated my version of Thunderbird by downloading the latest version and installing it as opposed to allowing Thunderbird to automatically update. The basic reason was my old version didn't support OAuth 2.0 which I needed to continue using my gmail account. After the update, I had 2 problems. First, my address book was empty but I have solved that from a backup Profiles folder I have. The second problem is when I start Thunderbird I get the following error message in the pane that would normally show the last email in my inbox:- "File not found

The file mailbox:///C|/Users/blogs/AppData/Roaming/Thunderbird/Profiles/ohv7zad7.default/Mail/Local Folders/Inbox cannot be found. Please check the location and try again."

The 8 digit default file is showing a different 8 digits to my actual Profiles folder. What do I need to do to prevent the error message appearing every time I start up Thunderbird, All my old emails are appearing as they should. Thanks PL

Login to my Thunderbird account has failed for the second time in less than a month. The first time it happened, the system seems to have fixed itself. This time, it is locked. See the attachment showing the error message. I vaguely remember being advised a few years ago to delete something in my TB and reinstall, that the content of my account is stored elsewhere and would reinstall. Is that correct?

A few days ago I got error message from Thunderbird: "Sending of password for user crangard65@gmail.com did not succeed. Mail server pop.gmail.com responded: Username and password not accepted.

Later the same day, after shutting down PC, got into Thunderbird without any problem. Has been OK for a few days then yesterday the same error appeared. I have no problem accessing my gmail directly via Firefox using my usual username and password.

Any suggestions?

Operating system is Linux 4.15.0-163-generic and Thunderbird version is 78.14.0, Build ID 20210901192859

Thank you.
