I now have 2 accounts in Thunderbird: Local (which has years of folders, but stopped receiving email from my Web mail provider) and my webmail Provider that does not download it from the provider. He claimed it is more modern and safer to synchronize across all devices and keep stuff on the web Mail application. I prefer to keep all my folders and emails on my local computer. Should I use POP? iMAP? to do that? Thanks for your assistance?'

When I open Thunderbird now I suddenly see a whole load of 'Recent Folders' at the bottom of my All Folders list.

All of my folders are suddenly all over the place. Please can someone help?

"Your Thunderbird profile cannot be loaded. It may be missing or inaccessible" keeps appearing mid-screen. version 147.0.1 re-installed several times (Win-10). Transfers of profile attempted from operating PC (Win-10) Cannot locate profile even in a "fresh Install" although the shortcut appears on screen and other associated files seem to be installed. Helps have been downloaded and tried. Same issue. I've received help suggestions from Lin and sfhowes both on 2-6-26.. Thanks for your help.

I use the "move to" function to move emails from my Inbox to various other folders. I use the function on a daily basis. Since the last update, when I click on "Move to", the Recent list is no longer alphabetized. This is very frustrating. When will the alphabetization be returned?

I used Thunderbird for many years, but starting in August 2025 it stopped working. It was getting an error in the smtp server, and I was unable to resolve that issue. When I try to login to Thunderbird now, it tries to send a message to pwrichcreek@twc.com, but that no longer exists. Thanks for your help.

bold textI recently had my computer get stuck in the "automatic repair" loop making it impossible to boot up. I restored a several months old back up onto a different hard drive. I can boot on the new hard drive, but Thunderbird is missing several months of e-mails. I have tried importing from the old hard disk, but IT DOES NOT WORK. Alll it does is create a new "Local Folders" with nothing in it. I have tried exporting the old profile to a zip file, but it is 14 GB, more than Thunderbird can handle. How can I import the old e-mails into the working version of Thunderbird on the new hard drive. Please, do not say "use the import function" as i have already found it does not work.

For the past few days when I open Thunderbird I get a message "https://caldav.one.com is requesting your username and password." (see attachment). I've never signed up for Caldav so I don't have a username or password. If I hit "Cancel" it proceeds as normal. If I enter my email address and log-in password it also proceeds as normal. In either case I have to go through the same process every time I open Thunderbird.

Something horrible and time-consuming has changed within this past week to Thunderbird. My version is 140.7 1esr 64bit. Over the past 4 days or so, I've found I cannot scroll down and see the full emails--until I have to use this new pop-up system.

This is definitely not an improvement in my estimation. Is there any way to undo this?

Hello! The other day everything worked as usual, and I shut down the computer for the night. The next morning, Thunderbird immediately crashed/shut down when starting each of the 2 profiles I always use. The 3rd profile, which is the default-release running a different email, still seems to work normally. Thunderbird 115.10.1

I have tried Windows (10) safe mode, as well as thunderbird Troubleshoot mode and working offline, but the issue continued to occur.

I'm at a loss now as to what could cause 2 profiles to suddenly cause it to crash. By the way, one profile is for a gmail account and the other one is for an Outlook account, so they don't seem to be related.

In case it helps, there were 2 Microsoft Visual C++ programs installed or updated, and updates to Microsoft 365 and Google Drive just before the problem started. These were all auto updates in the background.

Any help from the Community would be greatly appreciated. Thank you!

Hello! I want to set up TBird to: 1) Get all my messages and attachments stored locally, and... 2) Remove *most* of the above from gmail's server to avoid the data limit, but... 3) Keep, perhaps some months or a year of activity on gmail's server so I can access recent items from wherever.

Questions: 1) I have 10s of thousands (more?) of msgs, many with attachments. Is it better to just set up TBIrd and let it grab all the messages, or start by using Google TakeOut? 2) I presume I use IMAP vs. POP? 3) To preserve messages on my harddrive, I could archive to a local folder. Then I could safely delete those same messages on the gmail web interface? 4) If this turns into a disaster, can I just remove the entire account from TBird without suffering a loss of my entire email history? 5) Any insurance maneuvers to prevent the disaster of accidentally losing my entire email history while attempting to set this up? (Obviously will need to be religious about backing up my own system, though keeping a year of email on the gmail server offers a bit of insurance once the set up is successful.)

I am really hoping to avoid creating a unholy mess of my email/spending a week trying to fix it. (Indeed, I have avoided this project for years for this reason, but I really, really want to do this.)

‘I've had Thunderbird before on my Mac Mini. I'm trying to reinstall it but keep getting an error message: Thunderbird 147.0.1 drr corrupt image. I ran disk utility but no help. any suggestions please?

Hello, since friday, 6.2. thunderbird does not launch new (and also not completely all older) Emails anymore. So I can't see all my recieved and send E-Mails. In all my 3 Mail-Accounts froms different providers it does not work anymore, without changing anything from my side I know. But from my handy, where I use google-Mail, it works.

I already checked synchronization settings and repaired the E-Mail-folders.

So, are there any technical defects or problems with thunderbird, an update for instance that caused trouble for instance? And what can I do, to make it work again? Atherwise I would have to quit thunderbird and change my Host.

Looking forward to your response and already thanks for support, all the best, M.

Subject: Persistent SMTP block on specific Outlook account (IMAP functional) ​Problem Description: Systematic failure of outgoing emails via SMTP on Mozilla Thunderbird for the address redacted@outlook.be. Crucial Note: Incoming mail (IMAP) works perfectly with the same credentials, proving that the authentication and the password used are correct. ​Technical Data & Actions Taken: ​SMTP Configuration: Server smtp.office365.com, Port 587, STARTTLS (or port 465 SSL/TLS). ​Authentication: Using a 16-character App Password generated after enabling Two-Step Verification. ​Symptom: Systematic rejection of the SMTP connection (Command Error 12 or timeout). Other Outlook accounts configured on the same Thunderbird client and the same internet connection (Belgium) are working without any issues. ​Tests Performed: Complete purge of Thunderbird's password manager, alias verification, and full restart of network equipment. ​Conclusion: Since the reception service is operational and full access is functional via Webmail/Outlook App, the block is specific to the SMTP protocol for this particular account on the Microsoft server side. ​Request: Please lift any security restrictions or reset security flags for the SMTP service on this specific account.

How to connect email account!? I have been tring for days to set up email account incoming server settins accept but outgoing page despite green ticks will not let me finish, I am 80 and do not understand why I am being blocked when allsettings have green ticks??

Can not send emails through RoadRunner Mozilla Thunderbird. Can receive. Can send in Spectrum.net, so email account is working properly. Can send and receive with android phone, just not Mozilla. Can not check for latest updates.
