After auto update to 115.14.0 64 bit, Get Messages (from GMail) shows Inbox total rising and status shows 250 messages but no new messages appear. Each time I try to download messages the status shows the same number and totals increase by that amount. I've gone from 7000+ to almost 15000 trying various "solutions" i've found and tried. Last messages received were Sept 1st just before the update. Using GMail mail app (tremendously unacceptable) I'm able to view new messages but that app creates copious vacuum (S*KS). Background, I'm running a desktop on and currently updated Win 10 Pro with 400Gb free disk space and using No Thunderbird add-ins. As a long-time user of TB, this came as a big surprise and the only "solutions" I found even partially related were dated 4 or more years ago. These included: deleting certain profile files, disabling firewall, virus protection, and VPN. NoJoy! I'm almost to a point of backup, uninstall, re-install, and re-import but reluctant to do that because of 2 previously failed attempts to recover messages. If that is the only workable solution, please point me to an article that allows me to recover my previous message. Thanks in advance.

v115.10.1 I made a mistake setting SMTP credentials, wrong protocol, and it just stays on Sending dialog. So I abort when I realize I made a mistake and come back to mail I was to send. - but 30-60s after I aborted comes an error message saying it timed out

So the cancel button does not really cancel the send attempt, it seems.

Not sure where to report bugs, so do it here. Thanks.

I have been using Thunderbird for IMAP email for more than a decade. I have only two folders that contain emails on the server, Inbox and Sent. All the sent emails are there going back to 2009. I periodically move Inbox emails to local folders, but the emails from 2021 to now are still on the server. I see the headers for all of them in Thunderbird, but when I click on the header of an email from between mid-2022 and a few weeks ago, the result is blank. However, when I use my provider's Control Panel to read these emails, the texts and attachments are there, and I can read them. How can I restore my ability to read these emails in Thunderbird? I am hoping there is some simple setting…

Thanks for any help.

July 2024 - Thunderbird is demanding that I change my Hotmail password, after long trouble -free operation. It will not login. Why? (I have not changed the PW yet, hoping for a solution that will avoid the necessity.) I fear that it may be due to some fault in OAuth. Can anyone please provide any help to overcome this problem? Tom.

I get a message like this every time I start Thunderbird. The topic came up last year but the conclusion was along the lines of "...this problem will be fixed in version 128" but it was never clear whether or not the User followed Mozilla's support replies or what they had to do to clear the email message from Thunderbird. .....Well I'm running version 128.1.1esr and the problem still exists.

My questions:

1. What is Thunderbird trying to do? Compact individual email files? Compae from ct the whole Thunderbird Profiles folder?

2. Is the problem the size of the Profiles folder or the overall size of the hard drive the Profiles folder resides on? What is the Hard/solidstate drive is the maximum?

3. Is the problem related to the amount of Free Space left on the Hard/solidstate drive or is the issue the number of individual files?

4. Is the issue related to the number of Thunderbird files and/or folders OR is it related to the total number of files and/or folders on the hard drive?

5. Is there a limit to the number of sub-folder levels that Thunderbird can navigate?

Thank you.

Tom

I use thunderbird through vpn to my work site. I am required to use two accounts, one to login to thunderbird and download messages and a separate smtp password to send messages.

After logging into thunderbird, the first attempt to send a message works fine. It prompts me for my smtp account password and sends my message.

The second and subsequent times I try to send a message, I get the popup error:

``` The message could not be sent using Outgoing server (SMTP) relay.xxxx.xxx for an unknown reason. Please verify that your Outgoing server (SMTP) settings are correct and try again. ```

The thunderbird error console reports:

```

   mailnews.send: Sending failed; 
   The message could not be sent using Outgoing server (SMTP)
   relay.xxxx.xxx for an unknown reason. Please verify that
   your Outgoing server (SMTP) settings are correct and try
   again.

       fail resource:///modules/MessageSend.jsm:337

       onerror resource:///modules/SmtpService.jsm:211
       _onError resource:///modules/SmtpClient.jsm:510

``` Once I restart thunderbird, I can send a message again - exactly once.

Other mailer applications using vpn to connect to our mail system do not have this problem.

Thunderbird does not have this problem when I am connected directly to my site's internal network, not using vpn.

My thunderbird Outgoing Server configuration is:

``` Hostname smtp.xxxx.xxx Port 25 Username xxxxx@xxxx.xxx Authenticaton Method Normal password Connection Security STARTTLS ```

Those settings are consistent with my site's requirements.

I'm using thunderbird 115.12.2 on a mac running macOS Sonoma 14.5.

This problem first surfaced when I upgraded from thunderbird 102.12.0 to 15.4.1.

It really acts like things are configured okay, because it was able to send one message, but then something gets stuck after that.

Thanks for any insights.

I tried to send an email and got a message saying "The message could not be sent because connections to Outgoing server (SMTP) pop3.gmail,com failed. The server may be unavailable or is refusing SMTP connections. Please verify your Outgoing server(SMTP) are correct and try again". I checked and they seem right but I cannot even send an email from one account to the other. The same message appears and I don't believe anything has been changed, aside from adding another address, that I know of.

Thunderbird quit downloading just my work hotmail account in July 2024, the others are fine, settings are the same. I had the same problem with gmail during the pandemic and had to start it up from scratch, losing all my old emails. I do not have that luxury with my work account. Please help. Is it a size issue?

After years of using Thunderbird, today I received the attached error message. I am sending an email to another address within our company? eg, @doulton.ca

dave@doulton.ca sending to H2O@doulton.ca

Any help would be appreciated.

I received an email where I am part of a "grouped email" that the sender created. How do I expand the group email to see the other email addresses included in the group?

Since updated to version 128, Thunderbird is displaying email addresses in the form 'user name <user.name@domain>' where previously it only showed 'user name'. How can I revert to the previous behaviour? Thanks, Lucia

I am trying to consolidate emails using the Thunderbird identity feature. I have a single email account call it acct1@yahoo.com. I have three other email addresses that get forwarded to Yahoo, call them acct2@pobox.com, acct3@pobox.com, and acct4@hostmonster.com. I can send emails to all of these accounts. In Thunderbird yahoo is the default identity and the other three are alternate identities. The outgoing server settings are all identical (see screenshot). I can send emails using the acct1 and acct2 identities, but not the other two. This is puzzling because acct2 and acct3 are both forwarded identically.

The error message I get is not very helpful: Sending of the message failed. An error occurred while sending mail. The mail server responded: Request failed; Mailbox unavailable. Please verify that your email address is correct in your account settings and try again.

Hi. Same question as in https://support.mozilla.org/en-US/questions/1226211  : How can I customize the TB's main menu ?

I would like to remove menu items, which I never use:

• for simplicity
• to avoid accidental deletion (e.g. "delete folder", "delete message", "delete mail marked as junk in folder", etc.)

many thanks!

Today I changed my Google password, and now I can't login via Thunderbird to get email.

On startup, I am prompted with the Google login screen, which asks for my email or phone. I click Next, and get the message

   400. That’s an error.

   The server cannot process the request because it is malformed. It should not be retried. That’s all we know.

I'm using Thunderbird 115.10.1 (64-bit) on MacOS Sonoma 14.5.

I have Thunderbird 128 installed and just tried to get my gmail account set up. Everytime I try to add it, the Oauth window comes up, I log into Google, and then get a "malformed url" error and the oauth fails.

Anyone else have this problem with 128? Is there a workaround?

I use thunderbird with IMAP through vpn to my work site. Our site uses single-sign-on to connect to our mail server.

Sometimes my thunderbird client cannot authenticate to the server. The behavior is inconsistent. When I first start up thunderbird, one of 3 things happens:

a) Thunderbird logs me in via single-sign-on without prompting for my password.

b) Thunderbird gives me a login window, allows me to enter my password, and logs me in.

c) Thunderbird gives me a blank login window. The status bar at the bottom of the main screen says it is sending login information, but it has none to send. I never get logged in.

Under behaviors (a) and (b), the thunderbird status bar at the bottom of the main window says it is sending login information, opening INBOX, and downloading messages.

Sometimes restarting thunderbird or rebooting my laptop fixes behavior (c), and sometimes not.

When I'm connected, I can see my saved passwords via the Thunderbird Settings->Privacy & Security ->Passwords->Saved Passwords list. When I keep getting the blank login window, this list is empty.

I'm using thunderbird 115.12.2 on a mac running macOS Sonoma 14.5.

This problem was first noticed soon after I upgraded to thunderbird 15.8.0.

This behavior was duplicated by our support staff using thunderbird on Windows.

I don't have any data to show whether the problem happens when I am connected directly to my site's internal network. I'm not connected to that network frequently enough to be able to test the behavior, since it is so inconsistent.

My thunderbird server settings are:

``` Server Type: IMAP Mail Server Hostname xxxxx.xxxx.xxxx Port 993 Username xxxx@xxxx.xxx Connection security SSL/TLS Authentication method OAuth2 ```

Thanks for any help.

Hi, Recently Kaspersky antivirus (Premium) started picking up potential threats. It points to files in C: users\lther\appdata\roaming\thunderbird\profiles\tzldd93i.default\mail\pop3.iafrica.com\sent....

I have deleted the files in Thunderbird under sent files, but they still get picked up by Kaspersky. There is no option to delete them in Kaspersky, only to exclude or ignore. I do not want to manually delete all sent files, I cannot see the individual files in windows (win 10) anyway.

Is there a way to fix this. Kaspersky support have tried but no success.

Regards Leon

After posting a question here, I found the answer in one of your Help postings. So I deleted the question in this post (and changed the Subject), but was there a way I could have deleted the post itself?

Thanks for your help. Alan

I use Mozilla for incoming mail, but cannot get it to send mail out. I get an error message to check my SMTP settings, which I have done repeatedly, and it doesn't fix the problem. I use those same settings to send my mail OUT with webmail (which is inconvenient to have to switch all the time), so I know the settings are correct. Can you help me understand why my outgoing mail won't work even when I verify that the settings are correct.
