Sending of the message failed. An error occurred while sending mail. The mail server responded: <work@email address>: Sender address rejected: not owned by user personal@email address. Please verify that your email address is correct in your account settings and try again.

This message suddenly coming up after a Thunderbird update, and I cannot send messages from my work email because I don't "own" it. How do I fix this?

TIA.

When I delete a message, I would like to stop TB from automatically opening the next (or previous) email.

I have seen this question asked several times over the years but none of the suggested ways (mostly add-ons) work anymore. One add-on was called Mail Tweak and another was called Deselect On Delete but neither is currently available.

Is there a way to do this today?

I just migrated my email from cox to yahoo servers. The cox.net domain is retained.

I had never seen a "bulk" folder with my other domains and was having problems with emails being sent there.

I deleted the bulk folder and it moved to trash but cannot actually be deleted. I also re created a bulk folder. see pic.

Now emails are still going to the bulk folder that is in trash.

Is there any way to fix this?

Thanks

Over the last few weeks, emails have vanished from my inbox, as well as trash, templates and other mail boxes. In may cases, no emails are being displayed, when "total message count" shows messages are present. In other cases, several days of recent messages have disappeared.

I have tried "repair folders," deleting "smart mailboxes' and even deleting the .mlf file of one inbox without success.

I have 6 email accounts including 2 GMail. The problem is in all of them. As the screenshot shows, there is a disparity between total messages and displayed messages in all boxes (partial view of accounts).

Hi I am having problems with Thunderbird, i’m not sure if it’s to do with a windows 11 update or something else. Thunderbird is not responding also at the start of the ‘not responding’ emails from one of my accounts disappeared and then gradually started to reappear but didn’t get up to date and now just not responding st all. I have tried various things to resolve this, uninstalling and reinstalling Thunderbird, doing this and opening my pc in safe mode, doing this and opening Thunderbird in safe mode. Deleting and reinstalling the latest windows 11 update, reinstalling the latest Thunderbird update. I don’t know what to try next? I read somewhere to delete your profile, after saving it, and getting a new profile but no idea how to do this. Any help appreciated.

There is an email app provided by xiaomi on my phone.What in the email sent by this app contains a special format of `Date` fields.It looks like that: `Date: Thu, 2 May 2024 05:55:12 UTC` It doesn't look like others' `Date: Thu, 2 May 2024 06:05:15 +0000` or `Date: Thu, 2 May 2024 10:35:14 +0800 (CST)`

but it is still conforming to standards (or is it only parsable by the JavaScript Date method?)

After I modified windows time zone and restarted thunderbird. all emails changed time so this is not a time zone problem.

But this email shown two different times in the preview and detailed pages at this moment.

So can anyone tell me if this is a bug? Thank you.

Searching, nowhere to enter data; I cannot see attachments, looses mail, I have neuromuscular disease, hard to drag; context text EXTREMELY small. I think you all should create a TEXT BOOK [phone book size] on how to use. thanx!

Hi, Left post outlining TBird 115.x issues but I am the issue for the 'search' woes. The upper section simply needed to be shrunk - became a 2-headed arrow [when I figured it out.] Wonder whether other problems are also blatantly simply.

With Windows11 and Thunderbird 115.10.1, I am suddenly unable to send emails. It has been fine up until a few days ago and as far as I am aware, nothing has been changed.

I've gone into "sort-by" and tried enabling threading. I've tried checking the unthreaded box. Group job related email still just disappears. I can't find received group email in the trash or in the junk. I can't find any evidence in Thunderbird that the group email was received. If I go to a different email tool, there it is. Thunderbird is broken. If I scroll back in time and accidentally scroll past the date of the first group email, there it is. I can't be spending all day scrolling through months to years worth of email just to find out I got a group email from someone today. This is totally unreliable way to find an urgent work email.

I send .doc and .pdf files to my customers. When creating the outgoing email message and attach a file, I used to be able to see the file in the preview pane. I can no longer see the preview. Please help. This feature does work for jpg, tiff, and other image files.

Hi, after upgrading the programs to version 115.10.1 after restarting, all folders in the folder panel disappeared. I still have all accounts visible in the account settings. I attach a screenshot.

I follow someone instructions: Menu icon > Help > More Troubleshooting Information Under 'Application Basics' - Profile Folder - click on 'Open Folder' A new window opens showing contents of your 'profile name' folder Exit Thunderbird now - this is important Scroll down - delete all of the following files.

   folderCache.json
   folderTree.json
   session.json
   xulstore.json 

Start Thunderbird With no results. Thank you for any help.

In a recent email Thunderbird sees an HTML message as plain text, and does not decode it. The message is decoded by my phone using "Email - Fast & Secure Mail by Edison Software". See attached screenshot. Normally Thunderbird suceeds where phone apps fail.

All other HTML messages seem OK

Urgent Help Please as lost ALL EMAILS - I cannot get to post in Thunderbird: 1) I've now spent 4 hours, (from what was trying to sort a 'simple' problem on the server), as I couldn't send or receive any emails, as they think I've 6.5Gb of data on it, in spite of my deleting all my emails off it. So they allowed some extra space to temp sort it again. It's been an issue for about 3mths now. But I deleted everything just the other day having confirmed that was not deleting them off my laptop and that the previously lost emails 2 yrs ago weren't still on their server.

But now checked back on my email client Thunderbird, and I've no emails. They're all GONE bar the odd few I've put into folders (I stopped using folders years back as that lost all my emails way back then!), so I'd been keeping them all in the Inbox. Although I've a few old Inbox files with previous old old emails in so I can access them if I need to. But at least their there! But now again I've just lost everything. This is such a disaster.

Over the last 2yrs it's been going OK until today. Now it's LOST ALL MY EMAILS. I'm as per usual up to my eyes and have to travel this friday for meetings next week. The last thing I needed today was this. I've lost so much data and info in those emails it's doesn't bare thinking about. From show tickets that I need, medical info and data, to flight details to all sorts of crucial data. My ONLY saving grace is that anything I've replied to, I have a copy in the sent folder.

So Please Forgive this being in Firefox, as I can't even add it to Thunderbird help area!! I've had to reset my pw too just to sign in. Sadly right now it all feels so very upsetting I'm thinking I'll have to just have to start using another email client! If every 2 yrs I lose all my emails then this is just not acceptable. I hope you can move this to the Thunderbird threads. If you do please send me a link to it so I can try and find it.

What's so upsetting is had I saved the Inbox file when I saw the 13Gb file size, a bit eariler then, I think I could have saved them. I fear though that the remote server people deleted something, that was somehow still linked to my system and that's meant they've deleted my emails off my laptop too! Terrifying! (Perhaps that is what happened before back in '22. ???) I did look at a 'Sync' settings but not sure what they did so cancelled back out of them.

Running on Win 10 Pro 64Bit i7core 8Gb Ram Thunderbird 115.10.1 (64-bit)

Any and all help will be most gratefully received.

Sub issue to get help : 2) Error to Sumbit to Thunderbird: Sadly I've gone around and around your system saying Ask Question when nothing answers my query on the Thunderbird email questions. But when you click on Ask Question it just takes you back around the system again / Browse all Programs / re click on thunderbird/ reclick on Emails and back to list of FAQ's but nothing helps so click on Get Help and back around you go in a deja vu system.

I am unable to copy text and paste from body of email in Thunderbird. I was able to in past versions. When I right click after highlighting text all options appear but does NOT allow to copy anything.
