Having a problem with an ATT POP account. TB stopped getting mail. After a minute and a half or so (wish it would time-out faster), I get a pop-up box in the top right of the screen that states: "Connection to server inbound.att.net timed out" and then quickly goes away.

Deleted passwords and cannot see where to create them again, as it never prompts me for new ones.

Thanks.

I am setting up Thunderbird on a Win10 machine, and am having a lot of trouble adding accounts that I did not have on the two Win11 machines I have set the same accounts up on.

When adding my 2 GMail accounts, after clicking "Allow" on the OAuth popup the button would go grey the window would stay open and not close, and the account would not be added.

Changing the general.useragent.compatMode.firefox option to TRUE allowed me to progress and finally add those accounts.

I am now having the same trouble with my @hotmail.com account. When I add the account, the dark blue OAuth window pops up, but is completely empty, and there is nothing more I can do.

Things I have tried

  • Reverting the above config change
  • Checking that cookies and JavaScript are enabled
  • Checking there is no saved password
  • Used both the Account Hub and the default dialog, with the same effect.

Thanks in advance!

For many years I have had a Thunderbird Calendar, and have a large number of Tasks set up in it. I have now decided it would be convenient to link it to my Google calendar, so that it also shows on my new Windows 11 machine and on my laptop. I've gone through the process described in the "Create new calendars" article, to link the calendars, and the Google calendar is now appearing in the Thunderbird calendar, but not vice versa. How do I get the Tasks in the Thunderbird calendar to appear in the Google calendar?

I am running Thunderbird 140.7.1esr and Firefox 147.03 on my Windows 10 machine, which I used to set up the link. My Windows 11 machine has the same Firefox build, but Thunderbird 147.0.1, and the Google calendar display is the same, but I haven't yet set up the Thunderbird calendar on the new machine.

Is the feature supposed to behave this way? I find this rather tedious. Am I missing something here?

Current behavior:

My installation does not seem to automatically execute spam filtering for unified folders or saved searches. As soon as I manually select one of the included folders within - e.g. an individual mail acccount's inbox - the algorithm triggers and everything works as expected, but only for the one folder I clicked. This leaves me with having to click through all my mail accounts manually to make use of the adaptive junk mail controls function.

Expected behavior:

Selecting a unified folder triggers junk mail controls for all the included folders and moves messages to the respective junk folders automatically.

bold textI recently had my computer get stuck in the "automatic repair" loop making it impossible to boot up. I restored a several months old back up onto a different hard drive. I can boot on the new hard drive, but Thunderbird is missing several months of e-mails. I have tried importing from the old hard disk, but IT DOES NOT WORK. Alll it does is create a new "Local Folders" with nothing in it. I have tried exporting the old profile to a zip file, but it is 14 GB, more than Thunderbird can handle. How can I import the old e-mails into the working version of Thunderbird on the new hard drive. Please, do not say "use the import function" as i have already found it does not work.

Hi,

Since updating to Thunderbird 140.7.1esr (64-bit) on Windows 11, moving messages from Inbox to any folder takes about 7 seconds.

Details:

Account type: IMAP (Cogeco)

Happens in all folders

Inbox has ~600 messages (not large)

Was working normally before the recent update

Delay occurs every time moving a message from Inbox to another folder

No freezing — just a delay before the move completes

No antivirus changes

Issue started immediately after update

This appears to be related to IMAP sync behavior introduced in 140.x.

Has anyone else reported this, or is there a known regression?

Thank you.

Does TBird support plus addressing?

Scenario: I want to reply to email sent "To: markfilipak+joe@...". To do that successfully, in the "Write" dialog, I have to click on "From", scroll down to "Customize From Address...", click it, and add "+joe". (There is a menu alternative: "Options","Customize From Address...".)

If I forget to do that, then my reply does not have "+joe"; it goes out "From: markfilipak@...".

The Issue: When Joe replies to _that_ message, it does not have "+joe", so Joe's reply is trashed. (It's trashed because a filter I wrote automatically deletes messages that do not have "To: markfilipak+<something>@..." in the header.

The sensible way to handle plus addressing is for TBird to recognize plus addressing and to automatically make my "From" header from Joe's "To" header. That way, "+joe" will always be there.

Is there a way to do that?

Thanks Folks! -- Mark.

I am trying to create my outlook.com account in Thunderbird. I see the Account Hub box, and have typed in my email address. But when I type in the password, I get an error message, "Authentication failed. Please check the username and password". It then says, "Exchange auth error". I have checked and double- and triple-checked the spelling in the email address and password, and signed in to my email via the Microsoft outlook.com page using the same email and password. I can sign in to my email using the latter method, but Thunderbird keeps giving me the same error message and won't create the account in Thunderbird. What am I doing wrong?
