Thunderbird Support Forum

Hello. In our company, every employee has an IMAP account, but over time the IMAP profile takes up too much space on the hard drive (100-200GB per user...). What can we do to have more storage space? Can we delete the file? Or will all emails also be deleted from the server?

I've been trying out Thunderbird and Spark for the past few weeks, and decided to go with Thunderbird to replace Windows Mail. After uninstalling Spark, I changed all my email passwords, and now Thunderbird can't connect. I deleted my Google and Xfinity email accounts from Thunderbird, then closed and reopened the program, but I'm still getting this error from Google when I fill in the credential info it automatically asks for when re-adding it to my account:

"400. That’s an error.

The server cannot process the request because it is malformed. It should not be retried. That’s all we know."

On the "set up your existing email address" page in Thunderbird, I'm getting this error (see image), even though the copy/pasted password works fine when logging directly into Google.

I also can't reconnect to Xfinity at all. The 3rd party box is checked in their system, but when Thunderbird tries to connect, it looks like it's auto-filling and submitting a password on my behalf, without stopping on that screen so I can change it.

I did this: https://support.mozilla.org/en-US/kb/password-manager-remember-delete-change-tb

And tried all of the suggestions on this post: https://support.mozilla.org/en-US/questions/1434503

What am I missing?

I want to prepare emails in advance (in the Outbox folder?) and have Thunderbird send them later, at a time that I specify when I prepare them. I looked at the Events and Tasks tab but I can't see how to do what I want with a task. All the prepared emails can be sent at the same time. Can it be done? Thanks Peter M

I clicked the 'a' key on a folder in my email and a stack of emails disappeared. Some unread and some requiring a response! They're not in the archive folder.

Thanks!

Hyperlink insertion only works in troubleshoot modes but not in main mode even if all extensions and hardware acceleration are turned off (used this guide: https://support.mozilla.org/en-US/kb/troubleshoot-mode-thunderbird#w_the-problem-no-longer-happens-in-troubleshoot-mode)

Please help me.

Thank you!

I upgraded to Thunderbird 115.10.0 (x64) earlier today and now the program is no longer closing completely (I've tried using the X at the top right of the window, and I've also tried File menu -> Exit). I first discovered this when I was using CCleaner to clean my temporary items and it asked me if I wanted to close Thunderbird after I had already closed it. I then checked my running processes and there are three Thunderbird processes that remain after the program has supposedy closed (Task Manager screenshot attached).

Any help with this seemingly new bug is greatly appreciated!

Much thanks, -Snipe

Old computer: Windows 10 Pro, 64 bit Thunderbird 115.10.0 32-bit (Don't know why it's 32-bit version on a 64-bit computer or whether that's relevant)

The Profiles folder is here (with 5 profiles): C:\Users\<User>\AppData\Roaming\Thunderbird\Profiles

The new computer is Windows 11 Pro, 64-bit I just installed Thunderbird (V115.10.0 (64-bit) on the new computer.

On the new computer, the Profiles folder is here: C:\Users\<User>\AppData\Roaming\Thunderbird\Profiles

I followed the directions here https://support.mozilla.org/en-US/kb/moving-thunderbird-data-to-a-new-computer

I basically took the Profiles folder that came with the Thunderbird installation, renamed it (Profiles.orig) and copied in the Profiles folder from the old computer in its place. When I start up Thunderbird, I get this error message:

           Your Thunderbird profile cannon be loaded.  It may be missing or inaccessible

What am I doing wrong? I've updated Thunderbird on the old computer and copied the Profiles folder over to the new computer again. Same result.

Could it be 1. an issue with the user name on the old computer is different than the one I'm using on the new computer? 2. All files on the new computer are set up as local (the user on the old computer started out as a Microsoft user but I made it local so as not to have to use OneDrive).

I'm stumped. Any help will be very much appreciated. If you need any more details I'm happy to provide them.

Hi, Excuse my poor English (I am French). Linux Mint 21.3 Cinnamon (64), Thunderbird 115.9.0 (64) no added module - Installation from the Mint list of software. My problem : regardless of the provider (Proton, Gmail, Outlook, GMX - in IMAP), the message menu bar (see <https://support.mozilla.org/fr/kb/personnaliser-la-liste-des -messages#thunderbird:linux:tb115>) does not appear. How to make it reappear ? I think I have tried all the configuration menus and possible right clicks within Thunderbird ; I haven't found anything on the Net ; starting in safe mode did not change anything. I come from Windows 10 where I didn't have this problem. Thanks in advance for your help

I updated Thunderbird to the latest version and now I have a problem that continues to remain after closing the process.

Thunderbird 115.10.0 64bit (Build ID 20240412173147) OS Windows_NT 10.0 22631

Using TB v91.5.1 on Windows 10 x-64. I have several mail accounts, one of which is for a hotmail.com address. This has been working fine for years, but over the past couple of days, I don't seem to be able to send emails form this account. I can receive them fine, but when I try to send, I get the small pop-up telling me it's sending the message, and the progress bar is at 100%, but it doesn't send the message, it just sits there.

I looked in the error console, but nothing was added when I tried sending.

You can see my server settings for the account in the attached image.

Any ideas? Please let me know if there is any other info you need.

Thanks

Information on how to add the Google 'Tasks' into Thunderbird Calendar: I have a gmail imap account using OAuth2 as Authentication Method.

File > New > Calendar, select 'Google Calendar' >  click on 'Next' choose or enter: gmail email address   > click on 'Find Calendars' Select 'My Tasks' and click on 'Subscribe'

You may be asked to enter password as per Oauth2 Authentication.

See image. It shows the selection available when you follow instructions. It shows where 'My Tasks' is located in the Calendar list. I selected 'My Tasks' and then clicked on 'Task'. Create the Task and save. Task is shown in Thunderbird and on the right side you can see the Task is displayed via the webmail access using a browser.

In a world where respondent's often draft messages about a new subject by lazily replying to messages on an old subject, does anyone find Threading helpful? Why is it now the default.

After View/Sort by/Unthreaded then propagating that by "apply current view to all folders." All folders do in fact sort by unthreaded. But if I create a new subfolder it defaults to sort by threaded. Please, is there anyway to entirely disable Threading?

Answers to the question "how to turn off all threading in Thunderbird" no longer work with changed menu structures in Thunderbird 115. What is the answer to this question now?

Lately I'm having trouble with my connection with outlook. I use a free outlook email address. Sometimes (not always) when starting Thunderbird, I get the "user authenticated but not connected" warning. After a while it's working again.

I have tried several settings but can't figure out what solves this issue.

I'm using port 993 / SSL/TLS and authentication method is set to normal password.

Most of the times this works.

When I switch to OAuth2, I get the Microsoft screen to login to my work / school account which I do not have.

I've search the web to find a solution for this but I can't find it. Hopefully someone can help me out because it drives me "nuts" ;)

I am trying to import mails from Microsoft Outlook 2013 into Mozilla Thunderbird 102.3.2 (64-bit), but I get the error: No Profile found, see the attachment. I have set Microsoft Outlook as my Default mail app in Windows 10, my OS. But it didn't help. H.C. Enevoldsen hc@pushkin.dk
