Thunderbird Community Forum

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.

I have been using ThunderBird on Linux Mint for some time now. I am using Outlook.com for emails, calendar and contacts and I sync with another laptop and mobile phone. All fine until a few days ago when I noticed calendar events were not syncing with my phone. I found one calendar event in ThunderBird had an error when I manually synced with TbSync. The error report did not say anything specific. I deleted this calendar event and TbSync ran successfully uploading 2 events that it had not uploaded due to the calendar sync error. I then wanted to manually recreate this calendar event in ThunderBird. When I clicked on "New Event", the Calendar New Event pop-up window did not appear. When I minimised the ThunderBird window, the New Events was not behind it. The ThunderBird icon pinned to the panel had a "2" in the corner. When I hovered over the ThunderBird icon in the panel, it showed both the ThunderBird window and New Event window preview. When I selected the New Event preview window in the panel, it still did not become visible. All I could do with with New Event preview window in the panel was click in the 'X' to close it. I checked for Lightning Calendar Tab add-on updates. It was up to date. I check the settings. All OK. I disabled and enabled this add-on. Still not working. My Windows habits made me shutdown and restart my device. Still Not working. When I checked the other ThunderBird functions, New Event pop-up windows appeared for Emails and Contacts but not Tasks which had the same symptoms as the Calendar.

After deleting a large number of historical emails, including emptying the Deleted items folder, and emptying the Archive folder, Thunderbird restores a large number - but not all - previously deleted emails. Oddly the emails that are restored to the inbox are only ones from 2022. I have gone through and deleted them multiple times but they keep coming back. Any suggestions? Thanks, Simon.

I can't login to one of my email addresses. It says login to server with username failed. I tried all of the suggestions (using a pop server for example) and none of them seem to work. Please help.

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!

My Thunderbird crash whenever I tried to "save as" an email, save the attachment of an email, attach a file to an outgoing email.

Every time I did the mentioned, Thunderbird prompts the normal window of my laptop's folders, but it disappear in a second with the Thunderbird crash and quit.

This situation happened after I installed MS365 on my laptop.

I did try the below: 1. Reset attachment directory - mail.compose.attach.dir 2. Run in trouble shooting mode 3. Repair folder index 4. Clear cache

Anyone can help please?

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?'

I've attached a screen shot of the main folders seen when I view these as 'Unified Folders' with folders names starting with *01, *02, *03 etc. Somehow, *04 is no longer appearing in this list and has instead appeared inside the *03 folder as seen in my second screen shot. I don't know how this folder and the many sub-folders it contains was moved into the *03 folder and no matter what I do, I can't move the *04 folder out of the *03 folder to sit where it should between folders *03 and *04. Can anyone point me in the right direction to move the *04 folder into the desired location? Thanks in advance, SteveJ

I have been dealing with this issue for the last several thunderbird versions. I am currently running 115.18.0

Everytime I try to configure an existing gmail account for thunderbird via File -> New -> Existing email account

I specify my Name and gmail email address, then password for the gmail account.

The google authentication pop up launches " Mozilla Thunderbird wants to access you Gmail" and I click "Allow"

As soon as I click "Allow" I am asked to download a file.

Google gemini says this file is a sign that Oauth is not being accepted by thunderbird.

What I have tried. I verified Thunderbird is set to accept cookies I have verified there are no previously stored gmail passwords (as this has never worked) I have changed my default browser from Firefox to Brave and verified the same behavior

please help, Thunderbird has never been able to connect to gmail when running on this Ubtuntu install.

Does TBird support plus addressing?

Scenario: I want to reply to email sent "To: markfilipak+joe@...". To do that successfully, in the "Write" dialog, I have to click on "From", scroll down to "Customize From Address...", click it, and add "+joe". (There is a menu alternative: "Options","Customize From Address...".)

If I forget to do that, then my reply does not have "+joe"; it goes out "From: markfilipak@...".

The Issue: When Joe replies to _that_ message, it does not have "+joe", so Joe's reply is trashed. (It's trashed because a filter I wrote automatically deletes messages that do not have "To: markfilipak+<something>@..." in the header.

The sensible way to handle plus addressing is for TBird to recognize plus addressing and to automatically make my "From" header from Joe's "To" header. That way, "+joe" will always be there.

Is there a way to do that?

Thanks Folks! -- Mark.

"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.

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?

Running Thunderbird 140.6.0esr in Windows 11. This afternoon I found that one of my three accounts no longer shows up in the folder pane, though it still appears normally in the account settings tab. I can still send mail from it, but can't receive any. The other two accounts appear in the folder pane as usual and can send and receive normally.

Any help getting the account back into the folder pane would be appreciated. -- tralfaz

I am trying to create my outlook.com account in Thunderbird. I see the Account Hub box, and have typed in my email address. But when I type in the password, I get an error message, "Authentication failed. Please check the username and password". It then says, "Exchange auth error". I have checked and double- and triple-checked the spelling in the email address and password, and signed in to my email via the Microsoft outlook.com page using the same email and password. I can sign in to my email using the latter method, but Thunderbird keeps giving me the same error message and won't create the account in Thunderbird. What am I doing wrong?

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.
