Thunderbird ერთობის განხილვა

I cannot get the Subscribe function to do anything. I would like it to hide, in my Folder List, some of the extraneous folders that are present either as Mozilla defaults or AOL Mail flow-down folders.. From what I read, like a number of folks have simila or nearly similar duplicate Trash/Deleted Items, Sent/Sent Items & two labeled Drafts, albeit one's properties identify it differenet from its Drafts label as Draft (singular) while the other's properties identify it as labeled, Drafts.

For a cleaner Folder List appearance, I wish to hide the unused folders from the Foder List, I have the desired Sent, Drafts & Trash folder desitnations mapped in the TB Server settings, etc. (I assume there is only one avenue for this), thinking the unused foldes would then be available to be hidden. However, deselecting unwanted folders in Subscribe has never done anything, to any folder. When I return to the Subscribe window again, the deselected folders have been reselected.

I've seen a lot of messages here with many different suggesed remedies, but haven't found any one yet that was reported as being successful. Is there one?

Since some time my standard number of print copies in Thunderbird has changed from 1 into 2. I have to adapt this number each time I print. How can I change this back?

Hi.

Just had a not requested update to 153 esr, which in itself is generally fine, with a small exception.

The windows min, max and close buttons all come up with a code.

Probably just some weird setup I have but any ideas will be welcome.

I use userChrome.css to give a background colour, so maybe the ID of each has changes for any css

1. titlebar-min{height:1.66em; background:#00b !important}
2. titlebar-max{height:1.66em; background:#090 !important}
3. titlebar-close{height:1.66em; background:#d00 !important}

but I don't see how that would effect the actual bare icon

Thank you

I utilize a program to scan business cards and need to add these contacts into my contact list in Thunderbird. I know how to add them if the VCF Card is received inside an email as an attachment, but I do not see any instructions on how to add it if it is found locally on my computer or received by text, etc. Thanks in advance, Ken

Just updated to the latest version 153. No drag and drop ... message shown is 'Unspecified Error'. I made no changes when updating to this latest release. Appreciate some guidence. Thanks

Hello,

I followed the steps to use the vCard option as a Email Signature.

When creating a new email the vCard Signature is not appearing.

Please Advise,

Rodney

The certificate for pop.3marysvilleprint.com is not vailid for that server. Someone could be trying to impersonate the server and you should not continue

I want to copy my windows Thunderbird profile to Linux but my Profile Directory will not open when I press open directory. I downloaded Thunderbird from the Zorin app store, and it may be a flatpak or something – it won’t tell me now because I have already installed it – but I believe that could be a reason for the directory not opening. Is there a non-PC-literate way of finding out and fixing this?

I have had Thunderbird from the time I acquired my Mac computer. This week it started to do something new. After a restart I opened Thunderbird. A box came up that says across the top System Integration. The cursor balloons, and hasn't stopped for the time I powered the computer, as least fifteen minutes. You know how the program icons are in a dock across the bottom. With other browsers open, hitting the Thunderbird icon doesn't bring its window into the forefront. This needs either a reset, or possibly a backup first. Is there a quicker way to fix this? Thanks in advance. I am not using a VPN; but I also have Thunderbird on my Windows 11. You might have seen a more recent thread on that installation. I included a screenshot. It was easier here to do that than on the Windows 11. On the Mac, I just had to use Activity Monitor to close out of Thunderbird in order to get its version.

After the most recent update to Thunderbird, I can no longer copy attached files on incoming emails to either my Quickbooks program or a folder on the hard drive by dragging over. Now must copy manually to drive. Can this be corrected?

I am assisting an elderly user with a personal @hotmail.com account that receives email successfully in Thunderbird but cannot send. I have confirmed they can send and receive emails from their online outlook.com portal. The user's computer setup is as follows:

• Windows 11 (with latest updates).
• Thunderbird 153.0.2 (64-bit).
• A personal @hotmail.com account with the following server configurations:

  -> Incoming IMAP: outlook.office365.com, port 993, SSL/TLS, OAuth2, and
  -> Outgoing SMTP: smtp-mail.outlook.com, port 587, STARTTLS, OAuth2.

Thunderbird successfully authenticates to Microsoft using OAuth2 for incoming email. However, when Thunderbird attempts outgoing email authentication, Microsoft's SMTP server rejects the authentication. The Error Console in Thunderbird records this message: "535 5.7.139 Authentication unsuccessful, SmtpClientAuthentication is disabled for the Mailbox."

-> Refer to attached image: "Thunderbird Error Console_20260811.jpg". -> I am able to provide a short screen recording demonstrating the failure if needed.

To try and resolve the above, I completed the following actions:

1. Confirmed Thunderbird is current (153.0.2).
2. Confirmed SMTP is configured for OAuth2 rather than Normal Password.
3. Confirmed port 587 and STARTTLS.
4. Re-authorised the Microsoft account/OAuth connection.
5. Confirmed IMAP OAuth2 works.
6. Confirmed Outlook.com webmail can send successfully.
7. Reviewed Mozilla's current “Microsoft OAuth Authentication and Thunderbird in 2026” guidance, including the section covering cases where IMAP/POP works but SMTP does not.
8. Captured the SMTP failure in Thunderbird's Error Console.

However nothing worked, so I raised the matter with Microsoft support and eventually had the matter referred to their Tier 2 team. The Microsoft case number is: 7107041963.

Microsoft Support confirmed that for a personal Outlook.com/Hotmail account there is no user-accessible mailbox-level SMTP AUTH setting, and advised that SMTP is enabled by default for supported clients. However, because sending from Outlook.com webmail works, Microsoft Tier 2 declined to investigate the SMTP server response further and directed me to Thunderbird support.

I am able to provide a copy of the chat transcript if needed.

In any event, the TLDR version IMAP works using OAuth2, but SMTP using OAuth2 fails because Microsoft's SMTP server reports SmtpClientAuthentication is disabled for the Mailbox. Microsoft Tier 2 has referred the issue to Thunderbird support.

Questions:

1. Is this a known current issue affecting personal Outlook.com/Hotmail accounts using Thunderbird?
2. Is 535 5.7.139 SmtpClientAuthentication is disabled for the Mailbox known to occur with Thunderbird OAuth2 even though IMAP OAuth2 succeeds?
3. Is there a current Thunderbird-side workaround or alternative SMTP server/configuration recommended for personal Hotmail accounts?
4. Would changing the SMTP server from smtp-mail.outlook.com to smtp.office365.com be appropriate for a personal Hotmail account in Thunderbird 153, or should the current Microsoft-documented server be retained?

-> I note there appears to be conflicting advice on this point in previous support threads.

1. Given that IMAP OAuth2 authentication succeeds for the same Microsoft account, does this indicate that Thunderbird's Microsoft OAuth authorisation itself is functioning correctly, or could SMTP require a separate permission/token that may be failing?
2. Are there any additional Thunderbird logs or diagnostics I can provide that would help resolve this matter?

Disclosure: I used ChatGPT to help organise my troubleshooting notes and technical details for this post. The troubleshooting, observations and diagnostic information described above are from my own work on the affected PC.

Im looking for help to set up my Hotmail account. I have 4 emails. They all worked perfectly for a long time. All of a sudden, everything just stopped. I have tried everything and the configuration seems to be correct. Ive tried every fix i could find. It just no longer makes sense to me. Does it just not work with Thunderbird? The specific message is "User is authenticated but not connected". Also when i tried to send an email, i get "Login to server smtp-mail.outlook.com with username **********@hotmail.com failed."

Sending of the message failed. An error occurred while sending mail. The mail server responded: <support+idMM51X2-RWD3K@dealerbuilt.zendesk.com>: Relay access denied. Please check the message recipient "support+idMM51X2-RWD3K@dealerbuilt.zendesk.com" and try again.

the above is the error code. I have triple checked emails, even tried sending a message to my personal email as a test and nothing.

My Thunderbird install updated from 140.13.0esr to 153.0.2esr yesterday and now I can no longer drag and drop any attachment from an email to any folder on my computer. I simply get an error message window with a title of "Error Moving File or Folder" with "Unspecified error" text. See image attachment.

I've tried a variety of folders, including Downloads, Documents, Pictures and other folders on local and external storage devices.

I can save the attachments using the Save All button, or by right-clicking a file and choosing Save As, but not by dragging and dropping as I have done so for years.

I have checked if Thunderbird is running in admin mode, which it is not, but have tested it both ways with the same problem occurring. I have also run Thunderbird in Troubleshoot mode, and the same thing occurs. I tried clearing the startup cache from the troubleshooting page with no change. Restarting the PC did not resolve the issue, and disabling my anti-virus(Avast) also did not make a difference to the issue.

All was well until about six months ago. When I try to connect to my provider TB won't connect. BUT. At other times it will connect then every few minutes will try to connect again - then again .... I get this message "Connection to the server mail.comcast.net timed out". Then I get this message each time it fails "Login to server mail.comcast.net with username 170834000 failed". It keeps asking me to input my password even though everything is working appropriately. Then at other times it says it doesn't connect but it has connected and it still continues to ask me for a password.

I have uninstalled TB and reinstalled it thinking that would fix it - it didn't. I have changed my password - again to no avail. I let TB choose where to put things and configure each item appropriately. I don't try to get in the way of what works.

Comcast is apparently getting out of the email business and asking everyone to move over to their chosen substitute (Yahoo.mail) and I have not chosen to migrate at this point. Maybe that's the problem. This is the message I get each time I log into Comcast.net:

"A better email experience is now available for you

You're invited to upgrade your email account to Yahoo Mail, so you can enjoy a more user-friendly experience. Your email address, messages, folders, and contacts will not change.

With Yahoo Mail, you'll enjoy enhanced security, a built-in calendar that's easy to use, AI-powered inbox organization, and a top-rated mobile app for easy access on the go."

I am not aware of any changes in the settings from before when it was working well and now when it seems to be erratic.

I am not terribly computer savvy, but I'm usually able to trouble shoot and fix the issues that confront me. This time I'm out of my league! I need help.

Thank you for helping me.

Until recently, Folder Panes were visible at all times, but after the most recent update, they only appear when I am on a folder and are not visible when I am on a message. I have activated Views/Folders/Folder Pane Header, but that does not solve the problem.
