For a few months now I get a Send Message Error whenever I try to send an email from one of my addresses (see first screenshot below). I've checked my SMTP server settings and they all seem to be correct. (2nd and 3rd screenshots). I'm using the latest version of Thunderbird on Mac OS 15.3 Sequoia. I have no firewalls. What could be the problem and how can I fix it?

I have a new computer, Windows 11 Home. I have downloaded Thunderbird and added my primary att.net account by creating a secure mail key. I now want to add a second att.net acount (subaccount) and nothing I seem to do works. I use the same server settings as the primary and have tried using a new secure key and using my att password. What do I need to do?

I am De-Googling. My Gmail is still active but I turned off Thunderbird access via Google settings. I then proceeded to make vast changes to Gmail folder structure, labels, etc. because I mistakenly thought it was a good idea to start cleaning before I thought it all through. I went to Thunderbird to check for an email I deleted and realized it's going to prompt me to log in every time I open the app. I went looking for a solution and found out Thunderbird isn't set up for me to archive in this way. But can I?

I still have the Gmail account and will for some time as it was my main account for decades. I can connect it back to Thunderbird but I do not want any changes to folders or labels email location when I link it back up?

Is this possible?

If not, how do I move the account as it exists on Thunderbird so I have a usable offline account that will represent what I had before my mistakes? Thanks for your help

Good Afternoon! I am looking at an add on right on the Mozilla site. It's called "Edit Email Subject" (EES). This would allow me to organize my emails better by editing the subject line with more detail. I downloaded it, but Firefox tells me the Add On is not verified and cannot be installed. Yet it is on your site. It appears to be what I need, can you help - either by verifiying help, or (?) or by recommending another suitable add on? Reviews on EES were good, by the way. Help! Thank You, Allan

Hello and THANK YOU for Thunderbird and I am looking so forward to getting off Outlook! I am about 4/5 way through setting it up on my desktop.

I currently keep my calendar on Outlook. I have been able to import my folders, contacts and mail, but when I go to import the Calendar, the box on import cannot be selected. Is there something else that I need to do to bring over my calendar? Did I miss step when I did the initial set up?

I tried to Send an email, but the Send option at the top left of the email has changed to Send Later and the email does not send.

How do I change that option back to Send?

Background I wanted to give Thunderbird a shot because I really, really got tired of Outlook and their shenanigans. About 2 months ago, I tried it a first time and had an issue that prevented me from sending emails from my Hotmail email accounts. I gave up after a week of troubleshooting.

Outlook has come up with more bugs and shenanigans, so I tried again, convinced that there had to be a solution. And I found one. If anyone is interested, I was getting the error "Login to server outlook.office365.com with username <...> failed", and the way I fixed it was by replacing "hotmail.com" with "outlook.com" in the server settings. However, not all is fixed yet.

Current problem I noticed that the messages in my Outlook mail (other than the inbox) are not syncing properly. When I start TB, it appears to sync folders because I have seen new emails in subfolders already. However, if new emails come in while TB is open, it only syncs them if they are in my inbox.

I have looked around already and found that when I right-click that email account and I choose "Subscribe...", it presents me with an empty list and I can't see or enable/disable any folder subscriptions (refresh does nothing). This is strange because of 2 reasons: 1. All my subfolders are there, and they seem to sync when I start up TB. But even if I immediately open the subscribe window, the list is empty. 2. I have a total of 4 email accounts configured, 2 Outlook and 2 Gmail. All except for 1 Outlook account show me the list of folders in the subscribe window, so that made me think it was something in my Outlook account settings. However, nothing I can find there seems to be helpful.

Does anyone have an idea on how to fix this? I'd rather not close and re-open my TB app each time I want to check for new messages. I really want to give TB an honest chance but it's not making it easy for me to like it right now.

Running Chrome and Windows 11 with Thunderbird 128.7 0esr (32-bit) through Gmail.

Following a restart of PC, only primary Thunderbird gmail address functions. Secondary account is still in email account structure; however, there are no emails remaining (many were there prior to this restart), and I cannot send or receive from this account through Thunderbird. Account is still active in gmail.

Account settings in Thunderbird are same for both email addresses. Both addresses were established and have been used for more than 5 years.

Unsure if relevant, but after beginning to use OneDrive approximately one month ago, computer has been restarting without being requested, and have difficulties awakening the computer from sleep mode, sometimes necessitating having to force a restart with the power switch.

Any help would be appreciated. Thank you!

Hello, I have a huge problem with the recovery of my email messages. Due to a network error, I could no longer access my Thunderbird. I therefore had to (!) reinstall Thunderbird. Unfortunately, the reinstall could not access my backup files stored on a NAS drive (Q-NAP). All attempts to reconnect me to the network / NAS drive have also failed with 2 other PCs. However, the backup files are displayed via a PC still connected to the NAS drive. Then, in the hope of being able to transfer the backup via this way, I installed Thunderbird on this PC as well. Unfortunately, the recovery via the import tool does not work with this installation either. The methods described on the support page for "transferring Thunderbird data to a new computer" have also failed Is there still a chance to save / restore my email messages?

My company is switching to gmail and I rely on Thunderbird, so I need to add the account. I've followed instructions correctly, as best I can tell, but I'm sure I'm missing something. No emails are loading. I'm on Thunderbird 128.7, MacOS Sequoia 15.3.

Thunderbird now seems to have a new design for the message window which uses three lines for each message e.g.: Fred Brown Message Title blank line or link to replies

Is this new or have I accidentally changed a setting? I want everything on a single line rather than split across three. I can onlu now see 4 or 5 messages at at ime rather than the 15 or so I could see before. And with some 100-200 messages a day it is a rather tedious amount of scrolling to ensure I haven't missed anything.

Thanks

I wish to send an encrypted email. I have imported and accepted the recipient's public key.

When I compose an email to this recipient, the "encrypt" button is disabled.

Also, the security button mentioned in this article is not present on the compose toolbar, or anywhere for that matter https://support.mozilla.org/en-US/kb/openpgp-thunderbird-howto-and-faq#w_how-do-i-send-an-encrypted-or-digitally-signed-email

Windows 11.

Any idea how to fix this?

Many messages I receive do not wrap in either the message pane, or when opening the full message viewer (into it's own tab). See the images attached.

I've tried the following approaches (very old thread though): https://superuser.com/questions/702484/can-thunderbird-wrap-long-lines-of-received-html-mails

i.e. creating a 'chrome' folder under my profile, and a userContent.css file under that, trying several of the suggestions for content of that file. None seem to make any difference.

The example message pics here are sent from gmail.

Thanks in advance!

Can send emails but cant receive. Says no messages but I know there is emails that I have sent and can see on my phone. It does connect and states no emails to down load.Has done this before but cam with a confirm exception notice. No notice now When sending it does show a notice Email sent but could not save due to network errors Not sure how to fix this. Have searched but cant find an answer Thank you for helping

Yesterday I upgraded to Thunderbird Version 128.7.0esr. While all of the emails in my old inbox have reappeared in my new inbox, those that I had moved to local folders are no longer accessible because my previous Local Folders are no longer visible. The only 2 local folders that I now have are Trash and Outbox. I am using MacOS 15.3 Sequoia on a desktop.

I have been to Thunderbird Profiles and can find three entries for each of my previous folders (one with a .msf suffix) and one with .sbd). In ultimate subfolders there are 2 files named after each of my previous local folders (one has the suffix .msf), but they are not folders and do not seem to have any readable content. Please see example in attached screenshot.

Can you tell me please how to reestablish my previous local folder so that I can access the emails they contained.

Thanks

Sorry if this is in the wrong place. Did not seem to be an obvious one for my question.

I go tired of the Outlook web client always trying to us AI to assist me. Installed Thunderbird ver 128.6.1 esr on a Ubuntu 24.04 system running Cinnamon desktop. All components are up-to-date (or should be as auto-update is on). System details at end of message.

Screens for mail and tasks are rock solid. The calendar jitters up and down rapidly small amounts. Not the entire page. Just the part where the calendar is displayed. Makes things a tad blurry and is tiring to look at.

Any ideas on how to resolve?

TIA

I took an Apple macOS update last night and now my messages are showing in double spacing where they were much more compact and only single spaced before the update. It's not a deal-breaker but I would like to know how to reset the message pane back to single spacing as it was before. I tried looking up a solution on the web but different find anything easily. I am a monthly contributor.

Hi all, I just installed Thunderbird the other night and in trying to figure stuff out about it, I've hidden the button that allows me to change the way my messages are displayed. Nowhere in my settings can I see an option to show this again. Can someone please help? I've attached a screenshot of my Thunderbird window if it helps.
