Forum communautaire Thunderbird

Since changing my gmail accounts settings in thunderbird under Synchronization and storage so as not to store a local copy of emails. Thunderbird, after a while, is no longer able to authenticate to imap.gmail.com. If i delete the associated oauth2 saved passwords, restart and regrant access. Thunderbird is ok for a couple of hours but then fails again later. Thunderbird ran fine for a couple of days before i changed the synchronization settings.

Any ideas on how to eliminate this annoyance?

When replying to an email or sending a new mail I get the message :- An error occurred while sending mail. Server responded : You need to authenticate when sending mail from (ip address) Please check "message Recipient" and try again. How do I authenticate ? Thanks140.7.1

These are some things I have explored:

   • It is happening whether I look at emails in Thunderbird or through Gmail on Google Chrome
   • Even if I clickndrag them from deleted to inbox they fall back into deleted.
   • I’ve tried gmail/settings/all settings/filters and there aren’t any
   • I’ve tried gmail/settings/all settings/forwarding and there aren’t any
   • If I access Gmail via Microsoft Edge, the emails stay in Inbox
   • I’ve looked at various things in Thunderbird and unticked something in ‘When New emails arrive’ because I thought that might work.  

It started happening about a week ago.

The authentication is not working with many of the directions I have found online. I create an app password from logging into AOL website and have no where to put the password. If the password request is made is does not accept the password. Things aren't where the direction indicate. Getting the connection to request the password sometimes works but no password works. I tried the app password and rejected and multiple other password don't work.

Based on the latest version of Thunderbird where things seem to be changed, how to specifically set up this new authentication.

It's driving me crazy,

Thanks...Carl

As the title says, over the last two days Thunderbird won't do SMTP authentication to Outlook. It has worked happily for years and nothing at my end has changed.

I've the latest version of Thunderbird - 140.15.0esr (64-bit) - and this is Windows 11. It works happily from the Outlook desktop so the password is correct.

The authentication method is OAth2 and connection security is STARTTLS. Server is smtp.office365.com and port 587.

Anyone else having issues? Presumably MS have changed something (again)

Has anyone any suggestions on how to resolve?

After swapping to The Bat some years ago I decided to come back to Thunderbird again. So I installed Thunderbird 155.0.1 (64-bit) on my Windows 11 PC, and gradually re-created and connected the the accounts I had on the back. I also installed the ImportExportTools NG addon, then exported my emails from The Bat to Thunderbird. So far so good. However for some reason I created an account twice. There are both for the same GMX account, but one is POP and the other is iMAP. This mistake probably happened after a long session of setting things up and I just forgot about the first account.

I looked through the Thunderbird help and the answer most given was to the Thunderbird menu, select Account Settings, swap to the account you want to delete, and then press the large red DELETE BUTTON on the top level of its settings (next to the DEFAULT button). I've tried this and it doesn't work. There's no confirmation dialog (which is what I was expecting) and if I close and reboot Thunderbird the account is still there.

How can this be fixed?

The issue is that the text I type into the top level of account settings, which has Account Name, and Default Identity, doesn't save. Initially I entered the email address and Thunderbird found the correct details, but I was creating seven new accounts and was going to come back later and fill in the details. However, the details on this page don't stick, wand it reverts to blank entries (as shown in the attached image), and each account's name defaults to the email address. It's awkward because if I create a new message it won't add a signature because that gets cleared with the other details on this page.

This might be related to an earlier question I asked Delete Account button doesn't work. since it's on the same page as the DELETE button. This suggests to me that there's a script engine that I'm missing on my PC. This is only a guess. I use Fire Fox as my main browser, and Vivaldi as a backup. As I say, this is only a guess.

This problem happened after the September update. No changes to any message filters. I am not the only one having this problem. What changed in the update that could have caused this problem? I have had to delete the problem account from Thunderbird because every time I move the messages back to the Inbox in Outlook, Thunderbird would move them back to Delete.

Hello, I use the 32-bit portable 153;2 version of Thunderbird. But now when I label a message according to my list of labels by color, the selected message returns to its original color. Labeling no longer works, even though old messages retain their colors well. Thank you for your response. Ph. Costes

I understand that in the immediate future that Virginmedia.com will no longer provide email services for their subscribers is this true.

I can no longer use outlook due to being a basic BT email account user. Thunderbird recognised my account. But now says can find server. It may be my password is wrong in outlook, but it is so long ago, I have no idea of my original password. I’m using the BT Mail app on my iPad and iPhone which works fine, but want my past and present emails on my laptop as well. I’m using windows 10. Any help??

I have downloaded and installed Thunderbird Email on my computer.

I put in my name as requested. Enter my Gmail account and go through all the steps signing in only to get a message that there is an error and I cannot be signed in.

Extremely frustrating to not be able to use this app.

Will be uinstalling immediately.

Hey everyone

I need to remove the line that is added when you reply to emails. It adds added steps when cutting and pasting when I quoting emails when replying.

I have multiple profiles with multiple emails in each profile.

I found a thread here dated 2016 that instructed to add this to the css file.

I didn't have en excisting css file I could fine so I created a folder. >chrome > and put a userContent.css file within that.

This is code.

blockquote[type=cite] {

  padding-bottom: 0 !important;
  padding-top: 0 !important;
  padding-left: 0 !important;
  border-left: none !important;
  border-right: none !important;

}

Almost anything I try to do with Thunderbird, even replying to emails requesting advice, I come up with errors, such as:

Sorry, you have been blocked

You are unable to access thunderbird.net

upstream request timeout

upstream connect error or disconnect/reset before headers. reset reason: connection termination

Hey guys,

So I am trying to create a rule that will delete emails on the server that are 360 days or older.

I know you can go into settings...

>> leave messages on server >>>>>>For at most ,,,,,,,

But from what I have read that only deletes emails on server from when they were downloaded into thunderbird.

I am new to thunderbird so that wont work for me.

So I went into message filter....thinking this would work

>>>>>age in days > is greater than > 360 days >>>>>>>>>>>Delete From Pop Server

But nothing happens???? Help!

Your input is appreciated

I have a large number of filters, and an important email was processed to move message into a folder. but the filter had no rule that would apply to the message. all the filter criteria were based on the sender, but that email did not have that sender. the filter log shows the filter being applied anyway. I suspect the filter database is corrupted. How can I fix that? i noticed my version is slightly out of date, and I will update it, but I dont expect that would fix a corrupted filter database .

After a reboot and Windows 11 update today, Thunderbird (I believe it was v155) will not open. It asks for the password, then sits at [Not Responding].

I have copied my profiles (there are two, one dated 2023 with only a 1K .json file in it, and one created tonight while I was troubleshooting that's several GB and when copying, appears to contain all my mail folders although I can't access them directly from within the profile) to a separate location (my desktop).

I've tried the following (after checking previous questions here in Mozilla support):

(1) booting Windows into safe mode

(2) opening Thunderbird in Troubleshooting mode (Shift while opening), both in Windows safe mode and normal boot

(3) uninstalled Thunderbird from Control Panel, downloaded and installed a new copy of Thunderbird

All give the same result: "not responding", can't click anything. Can only wait or close.

I was able to disable an extension that I installed yesterday that had been working fine.

I'm also wondering if the problem is mail folders that are too large. I have some candidates for deletion but since I can't see any .msf files for them, I can't delete (because I can't open Thunderbird.

I'm leery of instructions to outright delete any Thunderbird folders/files because (1) I can't see my mail folders directly and (2) I'm self-employed and all my client and business emails are in there. Losing them woud be a disaster.

I'm tempted to try the Windows option of restoring my entire computer to an earlier point, say, this morning. But that seems like possible overkill if it's an issue with just Thunderbird.

I'm freaking out, please help!
