Форум поддержки Thunderbird

I just installed Thunderbird on a computer, current version, and it didn't update my address book or contact list off the server. How do I do this manually as I could not find something saying to "download contacts" or anything like that. There is the "Directory Server:" option but I don't know what that is or how to use it. I didn't do that on my other Thunderbird installation (Work Computer). My email server is Mail.com if that matters. Thanks

I've been running Thunderbird for years on Gentoo which has version 115.10.1 as the most recent. I don't send much mail so I'm not exactly sure when this problem occurred, but I'm unable to authenticate with my SMTP server. I have not changed any configuration. Some weeks ago a changed my password on the server, but I made the appropriate changes to Thunderbird password manager. All settings, username and passwords are 100% correct as I copy pasted all of them. IMAP on the same server (uses same credentials) works.

I have tried deleting and re-adding my accounts which did not help. I have also tried deleting my profile folder. All other mail clients (e.g. claws-mail, kmail, mailspring) with the same SMTP server don't have any problems sending mail. This problem seems to only affect Thunderbird and Thunderbird forks such as Betterbird.

I have no firewall and am using SSL authentication with cleartext password on the SMTP server.

I get the following output to console on attempted sending of message:

console.error: (new Error("Server error 503 Service Unavailable", "resource://services-settings/Utils.sys.mjs", 390)) console.error: mailnews.smtp: "Command failed: 535 Incorrect authentication data; currentAction=_actionAUTHComplete" console.error: mailnews.smtp: "Authentication failed: Incorrect authentication data" console.error: mailnews.smtp: "Authentication failed: Incorrect authentication data" console.error: mailnews.send: "Sending failed; Unable to authenticate to Outgoing server (SMTP) mail.kapsi.fi. Please check the password and verify the 'Authentication method' in 'Account Settings | Outgoing server (SMTP)'., exitCode=2153066805, originalMsgURI="

Please find attached screenshot. I have added 10 email accounts for 5 domains. Most of them are unified since I used the "unified [folders]" option. Unfortunately, Thunderbird ignores several email accounts. This seems like a bug to me.

from today I cannot download my gmail to Thunderbird, I'm getting always here below error code:

“400 invalid_request” or “Access blocked: App sent an invalid request,” it means the app uses an authorization method that Google doesn't allow. Google has safe ways for you to sign in and share your Google Account data with third-party apps and sites.

Please let me know how to proceed.

Thank you

Hi,

I have both gmail and btinternet accounts feeding in to Thunderbird. I can send emails from my bt account but not from my gmail account. When I try to send a gmail message a pop up informs me that the out going server for gmail has timed out. I have checked the server settings for gmail's out going server and it is set up as Thunderbird states but the problem persists.

Can anyone help to solve this problem please?

This is a recent issue. If I send an email with no images and no attachments, it copies the email into my "sent" folder with no problem.

If I send an email with even a small attachment...it sends the email, but "times out" copying the message to the sent folder.

I've checked the account/server settings, they are exactly as recommended. I've changed the sent files to "other"...no difference. I deleted and reinstalled Thunderbird...no change.

Ideas?

when I try to start Thunderbird, I get a window that says "Your computer must be restarted to complete a previous upgrade Thunderbird. Do you want to reboot now?. I've rebooted several times now, scanned with PC Matic, rebooted again, tried to uninstall in Control Panel, and get the same window. How do I fix this?

I removed an account (membershipsec.KLcommunitychoir@gmail.com) from Thunderbird but I am still being asked to validate my ID for that account every time I look at my email. It's a Google page that is displayed but it seems to be Thunderbird that is triggering it. How do I stop it?

I have Thunderbird 125.0 (64-bit) on Win 11.

Everything works perfectly, BUT..

If I select File->Exit then it just goes into not responding mode and I have to end task to restart TB.

If I just click X then the window closes but If I click my thunderbird icon to bring it back up, nothing happens.

I often have multiple TB processes which I have to kill.

On system restart, everything is fine unless I try to exit TB.

In case it matters, I have private ISP email acc, and 1 hotmail and 1 gmail acc.

Any thoughts appreciated.

Thanks Steve

Thunderbird always turns off the print server every time it is started. I am running version 115.7.0 on a Win 11 OS. This problem began when I last updated Thunderbird (I think?) Jim Teague

My mail is hosted on Hostpresto. Yesterday 'someone' (it wasn't me. I was in bed) gained access to my cPanel and email and deleted my only email address, then installed their own. All my mail gone. I was stupid though - I opened another email address with the same name as the old one and started Thunderbird on the pc. Of course, it synchronised to the empty folders!

Luckily I have another instance of TB running on another machine and it's all there - I am not internet connected there!

How do I bring the folders containing all the old mail from the 'safe' machine's appdata/roaming/thunderbird location to what will be my 'working machine' without it immediately synching to the server and deleting it all?

Thanks Andy

'Sending of the message failed. Unable to authenticate to Outgoing server (SMTP) mail.btinternet.com. Please check the password and verify the 'Authentication method' in 'Account Settings | Outgoing server (SMTP)'.

Hello

I have been using Thunderbird as my email service and not had this before. Yesterday, I had to change my password for emails with BT. I changed it on Thunderbird too but now I am receiving emails OK on Thunderbird it is refusing to send any for me and shows the above message. I can send OK from my web based BT email but prefer Thunderbird.

I haven't a clue what I need to do to solve this.

Can you please help? Please tell me is very simple steps I'm not very computer savvy.

Thank you

In my left tool bar I have:

xxxx@cox.net pop server followed by about 40 folders. This was the Cox email that is no longer in use.

xxxx@gmail.com followed by folders

xxxx@cox.net this is the new imap cox.net using yahoo.

Is it possible to move the bottom cox.net to the top, followed by gmail, followed by the no longer in use pop cox.net?

Thanks

I have three different computers that I can use Thunderbird to access my hotmail account. All three computers can have the exact same server settings. One computer refuses to send emails unless I cancel the send and immediately resend.. Thunderbird ver 115.10.1 (64-bit) Windows 10 Home Ver 22H2 IMAP Mail Server outlook.office365.com Port 993 Connection Security SSL/TLS Authentication 0Auth2 Outgoing SMTP Server smtp.office365.com Port 587 Connection Security STARTTLS 0Auth2 Take Note All three machines can have identical settings listed above or various changes like Normal Password instead of 0Auth2 and/or an Outgoing server can be smtp-mail.outlook.com with normal password or 0Auth2... One computer must be cancelled will sending and when resent, it goes... no problem...immediately. If I don't cancel and wait, for it to send on the 1st attempt, it will eventually timeout on the outgoing server. Then I might have to reenter a password. Very annoying. I have been doing this for years. It is my workaround....

The font size for the whole display is far too small. Also the viewing panel for each email is far too narrow but the text when writing emails is huge. Should I go back to an earlier version?

I drag-n-dropped an account (POP3) folder "inbox" to the "Local Folders". How can I return the "inbox" folder back to my account folder ? Drag-n-droping back does not work.

The height of the viewing panel for emails is far too small. I can only see a couple of lines of text at the most and am unable to reduce the height of the incoming list of emails as previously in order to increase the height of the viewing panel. I have been helped to increase the font size of the overall layout so that I can now read it better but the green button to declare that my problem has been solved tells me that the page isn't working!

When I want to print an email I want the body of the email and I do not want the header information. How do I remove this unwanted script at the top of the email? I have tried ticking and unticking the tick-box for headers and footers in the print dialog to no avail. This question has been asked before but was archived.

Is there a way I can make a filter that responds to the displayed sender (which may be different from the address)? For instance if an email has the header “From: "John Doe" <john.doe@example.org>”, can I make a filter check if “John Doe” matches a pattern?
