Error message: Unable to write the email to the mailbox. Make sure the file system allows you write privileges, and you have enough disk space to copy the mailbox.

I am able to send. But no incoming. I have archived my mail so that the incoming folder has less than 4000 emails. I have restarted the program and the computer several times.

Tbird #142.0 20250813171833

I received mail this morning and then began to get the error message. Disk space on all drives is sufficient.

In Thunderbird why do I (still) get repeated tabs for the same (INBOX) folder?

Many previous answers go back to 2022 with answers that do not work now (like find an add-on in Tools for deleting duplicates).

Hello. I have been managing events through Humanitix for several years. Copies of notifications of purchased tickets are always sent to my Thunderbird account (via GMail). For reasons not understood the Correspondent Column for these emails always displays an address that should have no association with my events. Humanitix have had a look and says the 'link-up' is not happening at their end. Has anyone out there had a similar problem, or at least understand something about this kind of thing?

The messages that were left in my Inbox folder overnight have become ghosts. The subject, sender, recipient, and date are shown but none of the messages show any content when clicked on. None of them can be moved, or deleted. This seems to be the same condition for the Junk folder where the one spam message that was left in the folder is also a ghost. All of the attachments in these messages have been downloaded but I still need the messages for the record. Is there some way to make them whole again? Thanks.

P.S. I just restored the Inbox and Junk files from the nightly backup and all of the messages became whole. I still need to determine what may have caused this and how to prevent it. Thanks.

How do I view the message headers on the emails I receive? I tried right-clicking in/on/near the sender's address area but there's no option that pops ups like in other email programs. I've searched "email headers" and nothing comes back. Am I missing the instructions somewhere?

I have a single email that appears to be empty, but I cannot delete it. When I open the message in a new tab you can see that it blank. I will attach a screen capture. I've tried everything short of reload Thunderbird to delete this particular email.

Hi team. The sent items of one of my clients email accounts seems to be invisible. It does show that there are sent times at the top of the window. When I send a new mail, that number increases by one.

Things I've already tried; Checked all account settings. Double checked things like "Place a copy in", "default Sent folder", " Subscribe" Checked all layout setting Checked all filter settings. Uninstalled and reinstalled software.

Any idea what could be the issue?

Hello. I have a strange problem. I have the latest Beta version with an IMAP account running fine. I need to add a second POP account. When I go through the motions of New Account > Email, the 'Account Hub' box appears were I can enter the name of the account and the email address. When I click Continue, I get two green ticks and it says Looking Up Configuration then it changes to a spinning blue circle. This stays like this indefinitely. I click the escape key to close the window.

Then if I go back to the New Account > Email procedure, it takes me back to the same box with the spinning blue circle and I can't start the process again. I have to restart Thunderbird to try again, but it still won't work. I have tried starting in Troubleshooting mode and disabling add ons but like the blue circle I am going in circles.

I have two computers and on the other one I have the original Release version. This adds the second POP account with no problem.

I am on Windows 11. Can anyone suggest something to try?

Hi, I use Thunderbird for Android Beta 12.0b6 and I have the following problems: 1. Most of the emails I deleted from the notification shade still show in my inbox when opening the app.

2. Since the last update, the gestures work poorly, I have to swipe 2 or 3 times in order to delete an email.

Please have a look into it when you have the time. Thanks

In an IMAP account I can create subfolders in all folders except the inbox. Subfolders created in the inbox become folders at the same level as the inbox. TB 140.2.0esr Screenshot of server settings, advanced attached.

I've been using Thunderbird email for a few years. I use many folders to organize my emails. Recently, when I attempted to move emails from my inbox to a folder, the emails returned to the inbox. It doesn't happen with all the folders, but it is happening more frequently.

What can I do to fix this?
