Thunderbird Support Forum

When I try to download messages on one of several POP3 accounts I get the 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. and it keeps downloading the last message I received before the problem started.

I have tried repairing the folder, clearing cache and even turning off my anti-virus for Thunderbird but to no avail. No problems on my other accounts

Hi there,

after re-installation I wanted to re-created my virtual search folder, displaying all status = new items of the various inboxes I have (as Unified Folders cannot be restricted just to Inboxes of the accounts).

So have created the search, saved as folder (stored as local and as folder in an IMAP account) - and when I now try to include the other inboxes in the drop-down - I just see the (unchecked) account from where I have created the search - nothing else. No sub-folders or other accounts with their sub-folders are visible.

How can I identify the root cause and overcome this issue?

Thanks for help RoadRunner

Thunderbird 115.11.0 (64-bit)

email on multiple computers using tbird we can only get it to work with one computer on each end - please help any help is greatly appreciated! We can only get it to work on one computer on either side.

Having tried to resolve so many issues and scrolling through all these multiple help topics, I'm wondering whether Thunderbird is just too problematic to continue with. At the moment I can't send or receive emails and I've hunted down every fix I can find with no result. Right now I have the issues in the images attached.

I updated Thunderbird to version 115.11.0 (64-bit), in the old version that I had when I clicked on an email with threads in a closed state, I could see in the email display box the initial text of each email in the thread with the sender's information and more, in the new version I don't see anything, the display box remains blank. Is this a bug, or do I need to change it in the setting?

Created several email mailing lists. Stored them in the Personal Address Book (PAB). I'm sorry, but Thunderbird doesn't seem to work like any other email client. How do I address an email using one of those mailing lists in the PAB. Tried typing the whole name of the mailing list in the To: field. Didn't work. I'm not entirely stupid but it doesn't make sense to me.

I was going through messages in my inbox, and filtering on Unread messages. For some reason, all of the messages were suddenly marked as Read -- either I hit some hot key combo my mistake or there was an error in the app. Is there any way to undo that?

Mac OS 14.5 Thunderbird 115.11.0: The quick filters don't find content in the bodies of the emails in the folder searched. E.g., melissa would be found in the email address or subject but not in the body of an email and the window comes up blank. I have only run into this in recent editions of TB. How do we fix this?

Hello, my Cox email account was migrated to Yahoo mail. I can receive emails but now I can't send emails from Thunderbird. I've triple checked server settings. Please help. Thanks-Vince

This is the message I get and it does this with all email addresses.

Sending of the message failed. An error occurred while sending mail. The mail server responded: Request failed; Mailbox unavailable. Please verify that your email address is correct in your account settings and try again.

Hi!

What is the way to tell thunderbird to index IMAP folders in global-messages-db.sqlite which are not stored locally?

And a more generally, how does this part work, message indexing and remote IMAP folders not stored locally? Here, after removing the database, thunderbird indexed only some very limited set of IMAP folders in the Gloda, but not all of the folders, despite all are checked for "Include in global search". Or maybe it didn't even index whole folders, - I can't say for sure.

Thanks,

I am running 115.11.0 on Ubuntu 22.04

I changed email SMTP servers, incoming and outgoing. First I migrated IMAP on the cloud between old host and new host. I connected Thunderbird using existing a profile, just changed server information. After that email started coming into Thunderbird. I discovered a bunch of the filters had been disabled with no destination folder. Not all of them. Just maybe half. It knew the destination folder for the filter because it was at top of window when I would look at filter rule. I had to use that as guide as to what destination folder it should go to, and it filters fine.

Why were all these filters cleared of destination folder?

So, like I said in the title...my Thunderbird minimizes to the tray, and every time I open it from the tray, it isn't opened full screen...maximized. It is restored down....like when you press that middle button, left from the X. I don't know it is called, it says Restore down when you hover it. I'm using the latest x64 bit version, and my OS is Win10 Pro. Let me just say, that it happens only if I leave my PC for a longer period of time, couple of hour and it goes to sleep. Once it's awaken, opening Thunderbird is not the issue anymore. Only the first time. Any ideas?

I'm having problems with the Cardbook add-on but it is up to date based on my version of TB. When I go into Preferences->Advanced-> Update 'Check for Updates' shows I'm up to date. However, when I check archived versions it looks like the last version that worked with a MAC release of less than 10.12 is 78.14.0.

I'm confused if I can upgrade to 78.14 and how I would do it?

Thanks for any advice

P.S. and yes, it's a very old Macbook from 2009.

Hello,

Whenever I start Thunderbird a brief, white screen flashes before the black background that I prefer loads. I have searched for a solution but found none. Could you help me getting rid of that screen? Thanks for any input.

Ii recently got a new computer. The old one was getting slow and \i worried about it failing. I am old, and have been slow about getting programs on to the new computer. I got Firefox installed right away, and after a week or two got Thunderbird installed. My problem has been with Thunderbird. On the new computer shortly after I got it installed, all of my incoming mails disappeared. So I went back to using the old computer for email. It was ok. This was several weeks ago. Suddenly this evening all of my emails on the old computer disappeared from the inbox of one of my two email accounts, the one I use most. Now it has totally locked up. Still that way after shutting it down and rebooting. I have looked through the help files and didn't find anything like my problem. I do know that I have never deleted messages. My computers both use imap. I switched from pop a few years ago when Mozilla suggested the change. Going to bed now. will check email in the morning, to see if it will work.

Whenever I try to delete or edit single instances of a recurring event in Thunderbird, it looks like it is gone, but if I close and reopen Thunderbird, it reappears. This happened only recently. I am using Thunderbird 115.11.0 in Linux Ubuntu 24.04. Please advise.

Good morning,

I can't deactivate the dark theme (the Themes Menu is inactive!), while another user has a light theme and works perfectly.

In addition, the writing of new messages is in white text on a white background!

How can I solve this problem. thank you in advance for your help

Cordially
