Thunderbird Community Forum

I am supposed to be on the esr release program, but today I was automatically updated to beta release 133.0. This is the second time this happened. Thunderbird shows a red screen, and recommends I install the last stable release, 128.5.0esr, which is what I want to do. But the last time, when I tried to go back to a stable release, it then wouldn't let me do that because it says the profile may no longer be compatible. I solved it painfully using timemachine backups of older profiles.

What is the simplest, safest way to downgrade, now that I am in this situation? And why is this happening?

Thanks for your help!

HELP! This new version installed today, and Thunderbird suddenly stopped running and no longer runs. I get the message: "A newer version of Thunderbird may have made changes to your profile which are no longer compatible with this older version. Use this profile only with that newer version, or create a new profile for this installation of Thunderbird. Creating a new profile requires setting up your accounts, calendars and add-ons again."

The message seems erroneous because it is running the newest version. Should I step back a version? If so, how do I do that?

Thanks!

Hi there,

I have looked for hours on your site on how to get thunderbird sending emails, I have attached this to my outlook account and used all the correct IMAP/Port/Server settings that are displayed.

For some reason when I go to send an email, it says to me that "login to server smtp.office365.com with username ****myusername**** failed" THEN it says "Unable to authenticate outgoing server (SMTP). Please check the password & verify the 'Authentication Method' in account settings, Outgoing Server (SMTP)" I have done all the above multiple times, I have even tried other settings, and it STILL DOES NOT WORK.

I would greatly love some help with this as it is now becoming very tasking and frustrating. Please can someone help me out ASAP as I would love to start making use of Thunderbird.

Thanks - Max!

Suddenly, bizarrely, some of my sub folders have disappeared. They are not "greyed out". They have totally disappeared. I now missing important content, that I need. I have been unable to find a solution by browsing on this forum. Can anyone help? And if they are gone for good, can anyone suggest how I can prevent this from happening again?

I use Thunderbird to download my email to my laptop (MacBook Air). I have 4 different email accounts that get downloaded -- 3 use POP. One uses IMAP. It is set up correctly with port 993 and security SSL. When I click on an IMAP message in my inbox, it opens blank, except for the subject line in the frame of the email. Sometimes it will fill out, but sometimes, especially lately, the blank message just sits there, taunting me.

I can read and respond to the message if I log onto the email server in a browser (Firefox, if it matters) but I want my messages on my laptop. I tried to switch to POP to see if that helps since my other 3 email servers work fine, but I can't make that work either. Thoughts? Thank you!

Incidentally, I do not need to save all my messages on my server. I'd be happy to delete them after a couple weeks, but I can't seem to make that happen either.

I use Thunderbird to check the 15 different email accounts that I have to respond to. On the 4th of June it just quit sending or receiving emails. I tried deleting some of my emails but it hasn't helped. Do you think I haven't deleted enough or would there be another reason for it to quit working.

Somehow, I now have a duplicate email account. Changes to either one are reflected in the other account. So if I delete one, the other one will be duplicated. Also recently, each received email is duplicated.

I can live with each duplicated email but would like to get rid of the duplicated account.

Thanks, Sue

How can I make the conversations to be displayed in the reversed order, i.e. if I have ten messages in the conversation, make the last one appear at the top line? Essentially at the very least I want conversations that have unread messages to be highlighted in the main view. How can I make that happen?

Dear Sir,

Since transferring from Heart Internet to Thunderbird, which was forced upon me, I have had numerous issues. Right now, I cannot enter my password as the password that I have is not accepted. In addition, I am unable to access my emails on my Apple cellphone.

I cannot reset my password as I need to be allowed access first and I cannot gain access without my password being accepted.

Yours faithfully,

After updating to 128.4.4esr I can no longer send email - NS_ERROR_FILE_ACCESS_DENIED. I can create a new message, hit Ctl-S to save and I get a dialog box of "Status: Creating mail message..." and a progress indicator that is at 100%. I also get an error of "Unable to save your messages as a draft. Sending of the message failed".

If I attempt to send and email I get the same creating mail message and an error dialog box saying "Sending of the message failed".

In the error console I see

• Bulleted list itemSending failed; , exitCode=2152857621, originalMsgURI=imap-message://[email protected]/INBOX#67121
• NS_ERROR_FILE_ACCESS_DENIED: Component returned failure code: 0x80520015 (NS_ERROR_FILE_ACCESS_DENIED) [nsIFile.createUnique]

I looked at my ~/.thunderbird directory and the permissions are 700. I'm on Ubuntu 24.04.

When I select an email without opening it, and press the Del key on my keyboard, the email used to be deleted - but recently this stopped working. I now have to open an email before I can delete it. Any idea what could have caused this to change and how to fix it?

I use google to host my email account. I use Imap with TB 128.5.0 esr. MacOS 15.1.1.

Recently, maybe after last OS update, older emails stored in folders (synced with google mail) have zero body text. The same emails are fine on my ipad and phone.

I have check that all folders are subscribed and forced a sync.

Help!

Thank you!

I've been using Thunderbird on my Mac for 15 years now. Never had any issues with it. Love it. My wife has been using it on her Mac for the last decade. Again, no issues.

Two weeks ago, Thunderbird was working perfectly on both our laptops. However, overnight, we both started having issues sending emails. Any email to anyone now takes over one minute to send. It is painfully slow.

Receiving emails? No problem. No problems with anything else. Only sending.

Specifically, it's sending it from our Bell email accounts (we live in Canada and use Bell for our Internet needs).

I have a second account using a different domain, and that one has no issues sending. Also, when I send an email using Bell's internet browser portal, it sends instantly. So there's clearly a communication issue between Thunderbird and Bell at this point.

When this problem happened, Bell sent us a text telling us that our 1 GB Internet speed will now increase to 3 GB. That's when our email sending problems happened.

I just spoke with Bell, and they assured me that nothing changed on their end. It's too much of a coincidence to think that they have nothing to do with this. However, after speaking with the tech, I'm wondering if for some reason Thunderbird has difficulties connecting to the 3 GB servers on Bell's end. The reason I'm suggesting this is that my laptop still shows 1 GB per second download speed. However, the modem shows 3 GB. The tech suggested that our laptops can't take in more than 1.5 GB. So it's bottlenecked on our computers' end.

It's possible that Thunderbird also has a bottleneck issue because they can't negotiate the 3 GB Bell servers.

In the past two weeks, I have downloaded the three different updates Thunderbird had to offer. However, we have left my wife's Thunderbird active version it when this problem started. As a comparison. No change on either system. We are both running M2 and M3 MacBook pros, so there's no chance of it being a hardware issue on this end. And again, this problem happened literally overnight.

Help?

When trying to paste a screenshot from my PC (Windows 11), it fails—it does nothing. I've been attempting to set 'mail.compose.attach_http_images' to true and selecting "Only HTML" in the "Compose messages in HTML format" settings, but it still doesn't work. However, the screenshot from the clipboard can be successfully pasted into the Paint app.

Do you have any ideas or suggestions for resolving this issue?

The Menu at the top of e-mail to be sent disappeared so I can's send e-mail. I was able to click "File" and then click "Send Now" for a few days but the menu bar just disappeared. [email protected]

I have several email accounts and in the left pane they are listed in the order I added them. I want to change the order so the more used accounts are on top. I try dragging and it does not do anything. I searched the web and only solution listed was to download an api, which I did, but does not work on ver. 128. How do I change the order that these email accounts appear?
