Hi,

I put some messages into folders yesterday and then created another folder and dragged the first folder into it to become a subfolder.

When I did this, I saw the new folder but it couldn’t be expanded to show the subfolders.

All other mail clients showed the correct hierarchy except Thunderbird.

Why is this happening?

Secondly, I post comments on the thunderbird blog regularly but they never show up. Where are they disappearing to? Are you receiving them?

I have the latest Thunderbird (128.8.1) on my win 10 pc. I have 3 email accounts On start up it is set to check for emails - it checks account 1, 3 times, accounts 2 & 3 twice each. If i select file - get new messages for.... and choose an account, it will check all accounts when account 1 is selected, some of them multiple times, it will check accounts 1 and 2 when account 2 is selected, and it will check account 3 twice whe account 3 is selected. It successfully retirieves al emails from ll accounts. It has been working correctly (just checks all 3 accounts at startup once each) for years, but just recently, it has assumed this behaviour. Not sure if it is related to a recent update. Any ideas ? thank you

mailcow just got keycloak oauth2 support. Does thunderbird work with keycloak oauth2?

https://mailcow.email/posts/2023/mailcow-idp/ - or is work maybe ongoing on that and there's a ticket I can track?

This is a strange issue. I've been using Thunderbird for over 15 years, and today, while working with a client, I attempted to click "New Event," but it was greyed out. After ending the call, I started troubleshooting.

Steps I’ve Taken:

• Re-added all existing accounts—no change.
• Tried adding a fresh calendar—received a strange error (which I didn’t copy) about encryption or a "request missing required authentication credential."
• Uninstalled Provider for Google Calendar and removed all accounts.
• Same authentication error—Google sign-in system wouldn't appear.
• Searched Google for recent similar issues—nothing in the past 30 days, nothing within the past year.
• Restarted my computer.
• Was able to re-add all accounts, but nothing is syncing.
• At this point, I’m completely baffled. No system changes have been made. I'm running Windows 10 with the latest version of Thunderbird and its extensions. My system clock and timezone are correct.

Any help would be greatly appreciated!

In Thunderbird 128.8.1esr (32-bit) Danish language version, on Windows 10, when a list of past notifications pops up, I cannot close them. Whether I use "Turn off" individual notifications one by one, or "Turn all off", nothing happens, except the first time I try, I can see at the bottom left of the screen that communication takes place with the server. But the notification doesn't disappear. On following attempts, nothing happens at all, until I restart Thunderbird, then again I get a long list of notifications from the past that have never been turned off.

As for individual notifications popping up at the scheduled time, I can mostly, but not always, turn them off.

The calendars are no google servers. The problem started occurring 2-3 months ago.

What to do?

I am trying to add a gmail account to thunderbird. I have the following three configurations. They all have thunderbird 136.0.1.

desktop windows 10 laptop windows 11 update 2025-03 23H2 desktop windows 11 update 2025-03 24H2

The desktop windows 11 version fails, and the other two work without any problem. I enter the account name/password, and thunderbird identifies the gmail server info. I enter 'done' and a gmail window opens. It says to allow thunderbird to connect to gmail, enter 'done'. After that, there is a google window that says 'Error 400', and it dies.

Note that the windows 11 version that works is older than the one that fails.

Any help would be appreciated.

My POP Thunderbird account is no downloading messages (Yahoo mail). This happened months ago and then started working again moths later. I figured Thunderbird had been fixed. But a few days ago it stopped again (the same day Yahoo Mail introduced a new format, but I don't know whether that's an issue). When I hit the icon to download messages, Thunderbird says the account is being processed. Sometimes it asks me if I want to download messages before going off line, but it still doesn't download (and I am Never off line). This applies to POP Thunderbird on three different computers. I need HELP

I have two email accounts and both setup easily on my MacBook Air but my second account will not set up on my PC. I get the error message Thunderbird failed to find the settings for your account. I have copied the same info from my MacBook..

hi, today after opening Thunderbird on my computer the message 'account verification' appeared. After entering the data I got the information verification successful. After reopening Thunderbird it turned out that the email history is incomplete / received - only the last few emails / besides the second email account is not displayed. How can I go back to the previous settings and recover the full history?
