Thunderbird Community Forum

I cam getting constant and continuous multiple security exceptions for p53-caldav.icloud.com saying it's the wrong site. I have made not changes to the thunderbird setup except for normal updates. i've confirmed these multiple times but they still keep coming. Any help would be great

Today I changed my Google password, and now I can't login via Thunderbird to get email.

On startup, I am prompted with the Google login screen, which asks for my email or phone. I click Next, and get the message

   400. That’s an error.

   The server cannot process the request because it is malformed. It should not be retried. That’s all we know.

I'm using Thunderbird 115.10.1 (64-bit) on MacOS Sonoma 14.5.

Hi,

I am running Thunderbird 115.10.1 (Flatpak) on Ubuntu 20.04. (no extensions except birdtray) I have 4 email addresses added to my TB, and I like to see all of them together, therefore I am using Unified Folders. When I am accessing Unified Inbox, TB is very slow and basically frozen until it loads this folder (often a pop-up appears that 'TB is not responding'). it takes between 30-60 seconds to load my emails (either on start-up, or clicking on another folder, then going back to Unified Inbox). Every other folders open almost instantly. I have to admit I have a lot of emails in the Unified Inbox (~20K), however the inbox of my main email has 18K, and accessing that folder separately is instant. So any operation, other than opening Unified Inbox, is quite snappy.

This issue persists since I upgraded to v115, even when I did an OS reinstall (also tried installing apt (v115.11.0)).

I have seen this answer: https://support.mozilla.org/en-US/questions/1428374#question-reply however, nothing changed by resetting the folder.

Happy to see thunderbird is doing better and better recent years. I think it is now the time to add an option to allow it automatically startup in the background on system startup, which has been asked for several years. That is a really useful option, why not just implement it?

I think there are 2 ways: 1. Just automatically startup in the background on system startup and receive messages 2. Register a service in the background to receive e-mails and pop up notifications, and in this case, we don't need to add this option

The first solution may be easier to implement, but the second seems better? Anyway, thunderbird should have one of them

BTW, add an option to minimalize when click on 'close' button. I know there's an extension for this, so why not just integrate it :-)

Thanks!

Hi, I’m trying to move from Outlook 2003 to Thunderbird 115.12.2 (64-bit). Using the import wizard fails. Tools > Import select Import From Outlook and the following message appears. “Either there is no default mail client or the current mail client can not fulfil the message request”. I’m taken back to the Import from screen with the addition of a red panel with “No Profile Found” on it. Outlook 2003 is the default e-mail client, checked more than once. I’m trying to migrate to thunderbird so I have no account setting, thinking they would be imported. My pst’s files have been moved to a directory on a different partition to the Outlook programme, tried creating a dummy profile using default Outlook storage and still fails. I’ve looked at converting pst files to mbox, but this doesn’t see to include the account settings. But I could add them manually or I can not import the mbox files or directory structure into Thunderbird. I’ve been messing around trying other things but nothing works. Internet searches, Thunderbird forum searches suggests solutions but all fails and the steps don’t match Thunderbird menu, etc in many cases. I’m stuck. Can anyone give any advice on how to migrate from Outlook 2003 to Thunderbird. Tools, Add-Ins or manual methods, anything just to get me up and running. PS I’ve two pst files, one is the default main Outlook.pst and the second a secondary store I created in the folders of Outlokk called Store.pst, beside the none default storage location everything else is standard for Outlook and Thunderbird.

I received an email where I am part of a "grouped email" that the sender created. How do I expand the group email to see the other email addresses included in the group?

I recently updated Thunderbird to 115.3.3. When the update was complete it appears to have split my profile into two and created two of Inbox, Drafts, Sent, and Trash. I use Earthlink which is the name of the POP3 account. Now there are Inbox, Drafts, Sent, and Trash for "Earthlink", and a set for "Local Folders". Junk and Archives are only associated with "Local Folders", and "Outbox" shows up under a "Local Folders" header along with all of the folders I used to organize received messages. When new messages are downloaded they appear in "Inbox / Local Folders". Nothing appears in any of the "Earthlink / ..." folders.

I don't recall exactly what it looked like before but there was only one set of the primary folders, and the local folders I created to organize my inbox. I have attached screenshots of the the folder navigation pane, as well as the odd organization of the "Account Settings" tab. I am admittedly not an expert. Any help is appreciated.

We cant download emails in thunderbird any version with mailboxes on exchange online O365.

SMTP works fine. Receiving mails is not working and it gives Retr 21 error.

I am viewing my emails, and I can see that some emails are not nesting properly. It doesn't happen all the time. I am expecting all emails in the thread to have the same subject. Please see screenshot.

Thunderbird had been working perfectly for years under Mac OSX 10.13.6 (High Sierra) until this morning. Now attempts to start it result in an error message "You can't use this version of the application 'Thunderbird_78_10_0.app' with this version of MacOS. You have MacOS 10.13.6. The application requires MacOS 10.15 or later." The app shows a modified date of July 12, 2024, i.e., this morning and a size of 434.7MB. Perhaps it auto updated itself without checking that the update was compatible with the environment? Any suggestions about how to reverse that update or otherwise fix the problem would be appreciated!!! Garth Fletcher

On my new T-bird installation, I cannot find a way to add Send-Receive as a customization of the toolbar area, nor do I find so far any other way to send-receive, aside from interval-based automatic sending and receiving, and of course composing and sending a new email. Em-client has an easily accessed send-receive button, as does my long-time Outlook desktop client.

In my new setup on T-bird POP, is there any justification for the Trash folder appearing twice, once as non-local folder and once as a local folder? Or is this just an artifact of having an IMAP option as well? There is no such thing as a downloaded Trash item, right? So in a logical sense, shouldn't the Trash folder in non-local be removable on POP, or just automatically disappear when POP is selected? There are no other folders duplicated between local and non-local, so the duplication just looks odd and confusing, even though it may be of little or no functional consequence. Is there no way to eliminate one of these two folders, perhaps the non-local one?

I have three POP addresses configured but TB will only send through the default account. If I select the "From" address to be different than the default account, I get the following error. Once I change the default account to the one I am sending from, the email sends fine.

Error: Sending of the message failed. An error occurred while sending mail. The mail server responded: SendAsDenied; mail1@outlook.com not allowed to send as mail2@outlook.com; STOREDRV.Submission.Exception:SendAsDeniedException.MapiExceptionSendAsDenied; Failed to process message due to a permanent exception with message [BeginDiagnosticData]Cannot submit message.

When there is an unread email in a thread, the title of the first message is underlined.

Is it possible to make the title of the first email bold (not underlined) like ordinary new massage, if there are new emails in the thread?

I saw a message on the webpage "About Thunderbird" saying that v115.12.0 would not ship, and is superseded by v115.12.1 Yet v115.12.0 just installed on my Linux Mint system, and appears to be the latest update. What gives?

On my old small laptop I wanted to increase interface font size. Erroneously thought that in layout.css.devPixelsPerPx I could insert the desired font size. I have inserted 12, now Thunderbird is unusable, some giant menu words appear but I cannot move anywhere. Can I I edit a configuration file manually to reset to a readable size? Which?

I'm needing to transfer a fair amount of company email from POP accounts to Gmail for Business.

I understand the typical response is to add the gmail IMAP account to TB and copy the messages.

I've tested this feature and it works great. However I'm unsure of the exact mechanism used. Mainly, is this transportation between servers encrypted?

The gmail IMAP account is setup to use SSL/TLS, port 993 and authentication method is normal password.

Can someone confirm these emails will be protected in transit? Thank you in advance.

From Sept-16-2024 Microsoft will deprecate Normal Password and require OAuth2 authentication on its email accounts accessed from Thunderbird and other clients.

I'm trying to convert my hotmail accounts on Thunderbird to OAuth2 authentication.

Server Settings Authentication can be set to OAuth2 because OAuth2 is an option in that menu.

But SMTP Server Authentication cannot be set to OAuth2 because OAuth2 is not an option in that menu.

Both Connection Security methods ( Inbound and SMTP ), are set to STARTTLS.

See screenshots, thank you.
