Forum Bashkësie Thunderbird

I was attempting to search for messages within a single (local) folder. But every time I enter something in the search pane or the quick filter pane, I get answers from dozens of different folders, people or accounts. Can I easily limit any search to just the folder I have selected?

I need assistance with a persistent Microsoft 365 authentication problem in Thunderbird on Windows 11.

My business email is hosted through GoDaddy's Microsoft 365 service. Thunderbird repeatedly fails when attempting to send messages, displaying:

"Login to server smtp.office365.com with username [business email address] failed."

We have attempted to troubleshoot this problem on several occasions without achieving a reliable solution.

Previous troubleshooting has included checking SMTP settings, STARTTLS, OAuth2 authentication and investigating Microsoft Graph integration.

Our earlier investigation also indicated that SMTP AUTH may be disabled for the Microsoft 365 account.

The mailbox works through Microsoft Outlook, but having to remember to use Outlook separately creates a risk of missing time-sensitive business correspondence.

I would particularly appreciate assistance with the following:

1. Establishing a reliable, supported connection between Thunderbird and my GoDaddy-managed Microsoft 365 mailbox. 2. Determining whether Microsoft Graph integration can resolve this without enabling legacy SMTP authentication. 3. Identifying any known compatibility issues involving GoDaddy-managed Microsoft 365 accounts. 4. Providing specific diagnostic instructions so we can establish why authentication is failing rather than repeating unsuccessful configuration changes.

I can provide screenshots, Thunderbird version information and diagnostic logs with sensitive information removed.

I would be grateful for detailed technical guidance because repeated attempts to resolve this issue have been unsuccessful.

• • Subject: Severe recurring UI freezes after upgrading Thunderbird from v114 to v150+ — application becomes unresponsive after being left idle**

Hello Thunderbird Support Team,

I'm experiencing a serious and persistent performance issue with Thunderbird that began immediately after upgrading from version 114 to version 150 in September 2026. The problem has continued through multiple subsequent updates and is now severely affecting my daily work.

I've been using Thunderbird for years, and it worked reliably before this major upgrade.

• • The problem**

Thunderbird launches normally and initially works perfectly. However, after I leave it open in the background while working in other applications, it frequently becomes completely unresponsive when I return to it.

Specifically: - Thunderbird is initially fast and responsive after launching. - After approximately 5–10 minutes, or sometimes after a longer period of inactivity, it begins experiencing severe lag or freezes completely. - When I switch back to Thunderbird, the interface is often unresponsive for several minutes. - I often have to force-close the application through Windows because it becomes practically unusable. - Restarting Thunderbird temporarily restores normal performance, but the problem eventually returns, when it's left idle. - The issue occurs repeatedly throughout the day and makes it very difficult to use Thunderbird reliably.

Importantly, this is not simply slow startup performance. Thunderbird initially works perfectly, and the freezing develops after it has been running for a while, particularly when left in the background.

• • Version and environment**

- Operating system: Windows 11 Pro, 64-bit - Thunderbird version before the upgrade: 114 - Version initially upgraded to: 150 - Subsequently confirmed version: 156.0.1 (64-bit), on September 29, 2026 - Problem first appeared: September 2026 - Problem still present: October 22, 2026 - Current Thunderbird version: 158.0.1

• • Troubleshooting already performed**

1. **Global search indexing:** I noticed that Thunderbird's Activity Manager frequently displayed "Indexing messages." I suspected that indexing might be causing the problem.

2. **Disabled Global Search and Indexer (Gloda):** Unfortunately, this made no meaningful difference. Thunderbird continued freezing even with global indexing disabled.

3. **Multiple Thunderbird updates:** The application has been updated repeatedly since the initial upgrade, but the freezing has persisted.

4. **Restarting Thunderbird:** Temporarily resolves the problem, but only until Thunderbird has been running for some time.

• • Additional unusual behavior: Google OAuth authentication**

On at least two occasions, after force-closing an unresponsive Thunderbird process, Google Chrome unexpectedly opened a Google authorization page saying:

"Mozilla Thunderbird Email wants access to your Google Account."

The page also indicated that Thunderbird already had some access to the Google account.

After clicking "Continue," Chrome redirected to a localhost address (127.0.0.1 equivalent, using a dynamically assigned port), which failed with:

"ERR_CONNECTION_REFUSED — localhost refused to connect."

I suspect this happens because Thunderbird is no longer running to receive the OAuth authorization callback.

I'm not sure whether the Google authorization issue is directly related to the freezes, but the repeated timing is suspicious and could indicate a background synchronization or authentication problem.

• • Impact**

I use Thunderbird extensively for professional correspondence and managing my translation business. These recurring freezes are seriously disrupting my workflow.

The problem has now persisted for over a month, despite updates and troubleshooting. It is becoming increasingly difficult to continue using Thunderbird in this condition.

• • What I would appreciate help investigating**

Could you please advise on how to identify the background process or operation that causes Thunderbird to become unresponsive after it has been running for several minutes?

In particular, I would appreciate guidance on:

- Whether this is a known regression affecting users who upgraded from much older Thunderbird versions. - Whether IMAP synchronization, background authentication, or Google OAuth activity could be responsible. - Whether there are diagnostic logs or performance profiles I can collect while Thunderbird is frozen. - Whether a particular database, profile component, or setting could be responsible without requiring me to rebuild my entire Thunderbird setup. - Whether there are known fixes or workarounds.

I'm happy to provide additional diagnostic information, screenshots, or logs if that would help identify the cause.

I would particularly appreciate a way to capture what Thunderbird is actually doing during these freezes, rather than continuing to try speculative troubleshooting steps.

Thank you in advance for your assistance!

Hi there, I’ve spent many hours trying to find an answer. Perhaps it’s right under my nose, but I just can’t seem to find it. Please help!

I’ve created extra folders in Thunderbird to keep my messages organized. Question: How can I locate a specific folder?

Example: I create a folder named "a555". I CANNOT FIND THE FOLDER "a555".

(why did I choose "a555"? It’s a unique combination of letters and numbers, which ensures there are no unintended search results.)

Searching for a message does reveal the name of the folder it’s contained in, but that’s not what I’m looking for. I want to be able to search for the folder itself directly.

I have tried searching using: Global Search (top right) – Ctrl + K; Specific Search – Ctrl + Shift + F; This Thunderbird forum; A general search on the internet.

Any answer would be greatly appreciated. Arthur Cerew.

Hello I have just set up Thunderbird successfully and I'm trying to fine tune it.

In "account settings>synchronization I checked to keep messages on this computer. I think I understand that that means all synchronized folders including inbox in TB will match up with the same on the server, headers and main text body. If I uncheck that setting while online, does that mean that all message bodies will immediately be deleted from my TB profile? or does it only apply to new downloads so that headers only are downloaded, until they are clicked on?

Yandex email account. Messages are constantly being received: “Alert from account [redacted]@yandex.ru: UID fetch message 5 uid 122: failure due to backend error”. The numbers are always different. Emails are being received and sent. The server settings — the ones recommended by Yandex — are configured correctly. But these notifications appear almost every second. What is the problem?

I want to create a rule that applies only to one folder. Essentially, I get various notifications that I want to keep for a couple of months, but don't need permanently (e.g. appointment reminders, visa notifications, etc.). I have rules that work properly to move the message to the correct folder, but I want to create a rule that will delete the message IN THAT SPECIFIC FOLDER after 60 days. I most certainly don't want to delete messages in the inbox or other folders that I need to keep permanently. 1. Is there a way to do that? 1a. If there isn't, can it be suggested as an enhancement? 2. If there isn't, is there a better way to do this that I can't think of?

I've added a screenshot of one of the rules that I've created that works correctly. I need to be able to delete that message without deleting any messages in other folders.

Problem downloading emails from Yahoo

For years there has been no problem, but about 2 weeks ago downloads stopped. Pane at bottom of Thunderbird says downloading message 1 of 292, but is is stuck at 1 and nothing downloads.

Today something different is happening, it downloads the first 80 messages then returns again and downloads same messages again, then repeats. I now have 17 duplicates of these same 80 emails just in the time to write this and it is still downloading the same 80 over and over again.

I have searched internet for solutions. I have done the following:

Updated to Oauth2 through Yahoo website. Thunderbird shows a saved login password oauth://login.yahoo.com, plus my correct email address, plus an OAuth2 password

Checked all server settings. All correct, e.g, pop.mail.yahoo.com Port 995 SSL/TLS security, and OAuth2 authentication method

From server settings page I tested connection to server which came back successfully

Same as above for outgoing server.

I have ample disk space on my computer and ample data capability on Yahoo account.

Confirmed not in offline mode. Confirmed cookies and javascript enabled.

BTW, I can access all my mail on Yahoo’s web page, but that is inconvenient. I really prefer access through Thunderbird.

I have deleted global-messages-db.sqlite and Thunderbird reestablished it. Did the same for popstate.dat, and inbox.msf

I even uninstalled Thunderbird and reinstalled it but no improvement in the problem.

I am out of options now. What to do? Thanks so much.

Hello Good day,

With thunderbird I have tidied up my e-mails at server at googlemail.com yesterday ?!

I have deleted 50 percent of "all-inbox" and of "sent messages".

This means that - before this - 12,9 GB of memory at googlemail.com were used. Now it should be at about 6 GB of memory used actually ?!

In thunderbird-window below it is said that 12.9 GB of memory are still used ?!

Normally it should be at 6 GB of memory are now used ?

Thunderbird says still "storage is 85 percent full" ?!

Have I to wait some days until memory usage is actualized ?

Thank you for answer. Greetz. dschinn1001

I understand that Thunderbird recommends managing spam by trusting senders in the Personal Address Book and/or Collected Addresses. For that to work, I would have to put the many companies who send me messages that I needn't reply to into the Personal Address Book. But I prefer to only put people I know into the Personal Address Book. So I looked for an alternative method of managing selected senders, and thought I had found one, but it's not working.

The alternative I thought I'd found was to use Message Filters. I created a filter I called "Whitelist", and in the Filter Rules dialog I said to apply the filter when it is run manually, or when getting new mail, and to apply the filter after spam classification (although when this didn't work, I also tried running the filter before spam classification). I said to apply the filter when the "from" address matches a sender that I wanted to whitelist. And I said to set the spam status for such messages to "Not Spam", and to move them to my inbox.

Nevertheless, emails from the sender I specified continued to be put into my spam folder.

Am I doing something wrong? If filter rules cannot be used to override automatic spam handling, why does the filter UI allow you to set the spam status to "Not Spam"?

Hello all, I'm getting "Authentication Failure" popups, even though Thunderbird works fine, sending and receiving. I researched various sources and all deal with Server Settings. All email addresses are correct with passwords.

But here is something I noticed: In account settings, left pane, under Server Settings, - Connection Security is set to SSL/TLS and - Authentication Methos is set to OAuth2 ... as usually recommended for both

However, going to the main window in account settings (same account), scrolling to the bottom, under Outgoing Server > edit outgoing server > Connection Security is: STARTTLS ...???

Is this maybe the reason of Authentication Failure? (different from Connection Security under Server Settings.

Any thoughts on that? Should both be the same? Thanks for now

I have a number of calendars subscribed in Thunderbird, some external ones along with my own one, One is an Awareness Days one. That is one I like to glance at daily, but at midnight GMT/UCT the blasted thing causes a whole series of notifications to pop up, one after another, one for each awareness day the following day is - and some days that's quite a few. It's incredibly annoying when I'm in the middle of something and am interrupted by the notifications. i want the calendar for me to glance at when i want to; I do NOT want the notifications from this calendar, but do for e.g. my personal calendar so can't globally turn off all TB notifications,

I have:

1 in calendar tab, in the list of calendars clicked on the mute icon so it's showing a bell with a line through it and says it is muted on mouseover.

2 In its properties> Edit Calendar, unticked Show Reminders, have nothing under the Add notifications.

3 Following a suggestion from the Google AI, changed TB to use its own notification display rather then the Windows 11 one.

But no effect: every midnight I get the damned parade of notifications getting in the way of the 3D CGI art I'm working on.

So how do I stop the notifications from that one calendar (other than unsubscribing from it)?

Hello, I’m trying to install Thunderbird email client for my IMAP domain and my POP domain. They are on the same server but different passwords. I don’t get a place to enter passwords. Why?

Good day Thunderbirds

I seem to have done something rather disastrous. This morning when starting up my inbox is empty and though i have sent test messages from other mail platforms and they arrive in my Gmail account they are not downloaded to my Thunderbird. I did change the Gmail conversation option, because i want each mail to be separated. The combining of all related mail confuses me. I have reset the option but nothing has changed. All the other folders are intact and if i open "All Mail" every message is still there including the added test messages. Can anybody figure out what i have done and help me restore my Inbox? What if i re-install Thunderbird or something like that?

Here's hoping. I really do not want to access my mail online via Firefox. Thunderbird is my only way of managing 158.0mail.

Hi,Please assist Every time I open Thunderbird it shows Software Updater(user account Control) But the Sofware is already up to date & this has been happening for over a week

I have been setting up a PC with Thunderbird for my mother. I want to move her off a "Messaging Company" email to an Outlook email address. Currently I have 3 email accounts on her PC: - Messaging Company - Outlook - Gmail (loaded for testing and because she has an Android phone) Messaging Company and Gmail seem to behave just fine, both for sending and receiving. Outlook seems to work fine for receiving email. For sending, it works when I clear the credentials and set them up again. This only seems to last for a while, and it's as if Thunderbird forgets the SEND credentials. I'm not sure if this is after a reboot or some other cause. I have walked through all of the relevant advice on OAuth2, STARTTLS, etc. I don't think it is a configuration issue at this level because I can send for a while. It seems to be something to do with retaining the credentials. Any help would be appreciated - if I can't get this going, then I may have to move here to the Gmail account but I have my own reasons for wanting to use Outlook.

Example why question is being asked:

Three separate GMX email accounts, each with its own unique password, and NOW Application-specific password for Thunderbird. Aliases are not used or desired. Three different separate accounts that should each have its own outgoing server.

Worked fine until updates to Thunderbird and changes to the GMX server, and Application-specific passwords became a requirement to send and receive email.

Seems like updates to nearly every program and/or app that may be released with the intent to resolve an issue or include a new feature breaks something else. M$ is horrible with updates and labels nearly everything as a critical update so it gets pushed through even when updates are turned off or supposedly permanently disabled by a registry hack; Windows 11 being the absolute worse ever. Why I only have one computer with M$ while all the others are Linux. Problems all the time with M$ while Linux simply continues to work.

Regardless, can setup each GMX account but the default email account name must be used as the user name on the other two GMX accounts on the outgoing server in order to send email. Then the recipient sees the name for the default account rather than the name assigned to the other two accounts, and the Application-specific password for Thunderbird must be changed to that of the default. Then attempting to pull down email for the other two pop accounts comes to a halt, and email messages can only be viewed by going to the online account.

Two separate accounts for yahoo, two for gmail, and one for Charter work fine, each has its own name and outgoing server. Should be the same way for GMX but is not because Thunderbird requires one of the three GMX accounts is set to Default.

Appears by having a Default email account, users are not only restricted by the default account, but email that is sent is done so with he incorrect name, The purpose for three different emails is for email segregation and better management; personal correspondence, business related, and Internet stuff.

Instead of having a 'Default' email account, makes more sense to use a valid email to register Thunderbird after downloading and installing, and then using that email for Support, Boards, assistance, etc. The default email requirement causes too many frustrating unneeded issues that should not occur, along with wasted time, stress and grief. Computers were suppose to make our lives easier and allow us more time for the real world. Biggest lie told since the Bell Labs created the transistor.
