Thunderbird Community Forum

I was referred here from Thunderbird Bugzilla report 2081665.

We are experiencing a recurring problem with Thunderbird 153 on several Windows workstations in a business environment.

The important point is that the problem also occurs with completely new Thunderbird profiles created from scratch. It is not limited to migrated or old profiles.

On one workstation this has already happened to three separate Thunderbird profiles.

Typical sequence:

1. Thunderbird 153 is installed. 2. A completely new profile is created. 3. Mail accounts are configured manually. 4. Everything initially works normally. 5. After some time the profile begins to malfunction. 6. Thunderbird Settings no longer open/respond. 7. The address books still exist, but address autocomplete when composing a new message stops working. 8. Creating another new profile temporarily fixes the problem, but the same behavior can return later.

Troubleshooting already performed:

- Troubleshoot Mode - extensions disabled - tested without the existing prefs.js - rebuilt Thunderbird caches and profile UI state - recreated indexes/databases - completely removed Thunderbird from Program Files, AppData\Roaming and AppData\Local - clean Thunderbird installation - clean profile created from scratch - Thunderbird executable and profile paths added to Kaspersky Endpoint Security trusted applications/exclusions

Removing prefs.js from an already affected profile did not restore the Settings window.

A clean test profile initially works correctly.

We have also encountered this behavior on other workstations. Some users have more than 100 message filters and many folders, so rebuilding profiles repeatedly causes significant administrative work.

Several affected computers had Windows user accounts renamed in the past.

We also experienced a separate issue where the Attach File dialog stopped appearing while drag-and-drop still worked. Bugzilla identified this as the already known Bug 2077590, so I consider that a separate issue.

For comparison, after completely cleaning Thunderbird from an affected workstation and installing Thunderbird 115.3.1 with a clean profile, the same workstation currently works normally.

Because freshly created Thunderbird 153 profiles can later develop the same problem again, simply recreating the profile does not appear to be a permanent solution.

Environment:

- Windows workstations - Thunderbird 153 ESR - Kaspersky Endpoint Security - multiple IMAP accounts - business environment

What diagnostic information should I collect from the next affected profile before replacing it?

I can provide:

- Thunderbird Troubleshooting Information - Error Console output - profile file names/sizes/timestamps - Windows Event Viewer logs - sanitized prefs.js - comparison with a working fresh profile

I'm using TB 157.0.1 on a Mac.

When I want to attach a file to an email, I click on Shift+Cmd+A.

I want to be able to navigate to a folder where the file is, then search for the file by name within the folder I navigated to. But it doesn't quite work that way.

I navigate to the folder, enter the file name in the search field, hit Return, and TB searches my entire hard drive. How can I force TB to limit the search to the folder I navigated to?

When I hit Return (or Enter) and TB searches the entire hard drive, the window that displays search results has a field I can click on that will limit the search to the folder I navigated to, but I'd like to eliminate that extra step. I'd like to set a default when searching for a file to attach so that search is limited to the folder I navigated to.

Is that possible?

Hello,

I would like to understand how to configure Thunderbird with IMAP accounts so that moving messages to Local Folders automatically removes them from the mail server.

I am currently experiencing this issue with Gmail.

1. Manual message moving

When I manually move an email from the Gmail Inbox to a Thunderbird Local Folder, the message is successfully moved locally. However, on the Gmail server, the message remains in the Inbox and is marked as read instead of being deleted.

2. Automatic message filters

I have configured message filters in Thunderbird to automatically move certain incoming emails to Local Folders.

The messages are successfully moved to the specified Local Folders, but instead of being deleted from Gmail, they appear to be archived and remain on the server.

Expected behavior:

- When I manually move an email from an IMAP folder to a Local Folder, it should be removed from the mail server. - When a message filter moves an email to a Local Folder, it should also be removed from the mail server. - Messages moved to Local Folders should retain their original read/unread status.

My questions:

1. How should Thunderbird be configured to achieve this behavior? 2. Are there specific settings for deleting messages from an IMAP server after moving them to Local Folders? 3. Does Gmail require additional IMAP configuration to ensure that moved messages are actually deleted rather than archived? 4. Is there a recommended way to configure message filters for this purpose?

My goal is to use Thunderbird Local Folders for storing emails while removing the original messages from the Gmail server to free up storage space.

Thank you for your help.

The email from ALL of my other active accounts (7 or 8 of them) all download fine.

Only ONE account throws off the Unable to Write Email to the Mailbox!

I have rebooted, I have compacted folders, I have repaired the folder - same result. Only ONE of my numerous emails fails to download messages.

ALL of the email databases are in the same subdirectory that Thunderbird (obviously) has complete read/write access to.

What now???

Can't get rid of this spam: ecare.all.r@emailff.att-mail.com Unfortunately I clicked on it and multiple spam sites came up. I've tried the spam filter and it doesn't work. Suggestions?

What do I do about this warning I am receiving when I refresh my inbox? "The certificate for pop.windstream.net is not valid. Someone could be trying to impersonate the server and you should not continue"

   Unable to receive new messages on my Thunderbird inbox for this warning

Since updating to the latest versions of TB I keep seeing ??? in messages. When I search in Firefox it says to change message encoding using an option under the view menu. But I can't find such an option.

Can someone please tell me how to fix this?

Thanks.

I am unable to access my emails in Thunderbird. Thunderbird opened but does not respond as there appear to be some files /emails that it could not accessed.

I tried deleting the Parent.lock file. I then deleted Thunderbird and re-installed it.

On opening the updated instance, it comes up with the same couple of files/emails in the list. With the same ones seemingly trying to be loaded. See attachment. The files are Invoice 03-10-20 and Ticket_1.pdf

From the day when I started using Thunderbird Mail client, from that moment only, McAfee is notifying me after every 5 seconds of a Trojan Threat

C:\Users \Pankaj Jain \ AppData \ Local \ Temp\ Trojan:Win / SuspiciousAttachmentScript.a

And the moment I uninstalled Thunderbird it stopped notifying it. And then I reinstalled it, same started happening. It hijacks the system and if I am writing, it stops that and wants me to see that notification (which all antiviruses wants to). Even worse is that I cant find any setting in McAfee to stop this notification.

I am frustrated now. Can you help on this?

When I try to send out an email, I receive an error message that states, Sending of message failed. An error occurred while sending mail. The mail server responded: <cjmst61@charternet> sender rejected. Please verify that your email address is correct in your account settings and try again. I have checked my settings and still can't send

Downloaded Thunderbird update and program now opens to Xfinity but no updated emails... Can I remove and re-install it without losing all my previous emails and contacts? Or is there any better fix?

• NOTE* It's Version 158.0...

I have been using emails without problem until recently but since a few days ago, it suddenly happened that I now cannot attach files. I have reinstalled software but still I cannot. I was asked to ask email provider so I asked nifty but they have not responded. Another issue, after reinstalled software, description is now shown in English. I can understand it but I would like to know how it can change to Japanese. I would appreciate very much if someone can help to solve this issue. Thank you very much. redacted@nifty.com

When I installed Thunderbird, I selected Custom Installation, thinking I would get an opportunity to select which components I wanted installed. All it allowed me to do is define the installation folder. Not very "customizable." Anyway, I already have a calendar app that I'm perfectly happy with, don't need a task manager, and don't use chat, Is there a way to remove those apps from Thunderbird?

Have got a replacement computer, and downloaded the latest TBird (having used it with AOL) for years). Following initial set up procedure, TB detects correct settings for AOL and the "enter password" page opens from AOL succcessfully for authorisation. AOL requires 2 factor authorisation, and I use a phone code for this.

However the speed at which the code arrives from AOL has always varied quite a bit, and today it is taking almost a minute so the TB set up screen is timing out long before the code arrives. Cant go on retrying as I will get locked out of the account. No point in going for manual set up as the auto settings are correct, so the same problem is going to occur. I have three AOL e-mail addresses to set up! Is there a workaround of some sort for this - its terribly frustrating and the set up screen "connect your e-mail settings" timeout period does seem quite short if you have to wait for a 2FA phone code or e-mail code - any delay in the arrival of which is completely ouside your control .
