View > Folders > Folder Pane Header [v] All Folders All folders is greyed out (cannot select).

I believe being able to make this selection would cause the email account name to display expanded selections. I want to be able to select this for all my email accounts to display properly in the Folder Pane: (example) Inbox Drafts Sent Spam Trash

Uploaded images are:

1. 1. View > Folders > Folder Pane Header > [v] All Folders > All folders (is greyed out - cannot select).
2. 2. My email client name list with no expanded selections.
3. 3. An example of and expanded email client name

Any help would be greatly appreciated.

Thank You

On my laptop when I try to send an email the spell checker box appears. I have tried turning thunderbird off then on again but with the same result. This first happened after I tried a spell check on an email which did not work (did not check the text) and all the time since every time I try to send an email all I get is the spell checker box. To send an email I have had to come out of Thunderbird and go into Yahoo mail to recover the draft and send it that way. I would apreciate any help you can give me. A second issue is that my phone app does not talk to talk windows 10 laptop. This is probabley a setting problem as I can get Inbox but cannot get Drafts (tried to send email by phone but Drafts was empty). Thanks Peter

Hello,

Windows 11 OS / PC

Basically I have Thunderbird installed on my second hard drive. I had several folders of different programs in that drive. I was basically trying to clean up those folders, so I made a folder called programs, and was dragging program files into that folder.

I dragged the whole Thunderbird folder into that new folder. That was where my issue started. After that, the desktop shortcut I had for it wouldn't work. Ok, easy, I went to the Thunderbird folder, found its .exe and voila, made new shortcut.

When I opened that up, it was basically like a new install, asking me to set up username/password pop/smtp etc. I'm decently ok at this, and I know that your Thunderbird profile can just be put in and it will pull everything back up the way it was, only, it's not.

When I looked in the AppData profile area for Thunderbird, it had a profile that was listed at 6:53, 7/22/2025 the exact time I moved the whole folder, and created the new shortcut...

So, my question is, how screwed am I? When I built my PC, I imported the Thunderbird profile over from the old computer to the new one. This was on 12/31/2023. So now, I see no other profiles but from 2023, and from the screwup date, today 7/22/2025.

I should also mention I tried messing with Thunderbird again later this evening, and it made another profile, 10:30 7/22/2025. I knew this wasn't right, and deleted it. So now, when I click on the Thunderbird shortcut, it says profile cannot load Thunderbird, profile is missing / inaccessible. So, Thunderbird won't even load up.

I'm wary of doing a fresh install, as I'm thinking there should be a profile dated between 12/31/2023 and today 7/22/2025, and I don't want a new install to wipe everything if the correct profile is hiding in there somewhere.

If I somehow figure out how to get the main program working again, please tell me the current data from Thunderbird before moving the folder is stored on that original 12/31/2023 profile. I really really really hope the correct and current profile wasn't wiped out when I moved the folder.

Is there a way to do a Windows restore to get it back if it is truly gone? If it is not truly gone, is it still the 12/31/2023 profile (Thunderbird just updates that original profile and keeps the original date that was transferred to the new computer)? If not, how can I find the current one I had before moving the folder? And how can I get Thunderbird to load using that profile?

Thank you for taking time to read this, and if you can help me get my Thunderbird back, you are a God among mortals!

Have been using 128.4.3esr since released and all good and found no reason to update. No changes to the system and my android operates as normal w/ comcast. In the last ~4 days seems email is delayed, but received, send works but seem slower and always upon exit get a TB dialog saying "Could not connect to servermail.comcast.net; the connection was refused". I used to know how to provide log info, etc, but getting old. Dell desktop win 10 64-bit 22h2.

Since updating to 141.0 64 bit today (Jul 22, 2025) my addon Filtaquilla is disabled.

I tried another attachment saver and the same thing happened. Okay, I'll revert back to previous version.

Can't do that without starting a new profile.

Sure glad I donated to Thunderbird last night.

I am receiving a notification that states "The certificate for mail.morrisbb.net is not valid for that server. Someone could be trying to impersonate the server ". As a result I am not receiving any emails through Thunderbird, but I can go to the Morris Broadband website to colllect them. I have used Thunderbird for many years without a problem. I don't understand what that notification means. I don't even know what a certificate is! So, in short, I don't have a clue how to fix this issue. Can someone please give me a clue as I'm clueless. Also, I turned off my antivirus program (Malwarebytes) and that didn't help at all. I appreciate your help!

I have a folder created from a saved search. It shows all unread messages across all my folders. It's by far the folder I use the most often. I often scroll through it and sort the messages into other folders. But when I move a message, I often end-up with 2 copies: one stays in the original folder and a second appears in the folder I moved the message to. (I'm not using COPY, just MOVE). Any idea what's going on or how to fix it?

An error message is repeating at random times asking to provide credentials for imap.gmail.com. When I select to proceed, a 400 error occurs indicting "the serve cannot process the request because it is malformed. It should not be retried". When I check google, email directly, there does not appear to be any problem with the account. What might cause this problem?

I am moving my wife's info from a Windows 10 laptop to a Windows 11 one. I followed all the steps in "Method using a transfer device" ( I used a large external SSD for that) and the document I was following had a second section about the possibility of an update to Thunderbird requiring me to create the new profile manually.

It did not work out, so I set to repeating the process, but have misplaced the printout with that second section.

Now, when I get to launching Thunderbird on the new system, the 'Enter your password' dialog comes up and asks me to "Enter your password for cch@clivedencom on mail.cliveden.com." Clearly, I have SOMEHOW mistyped that in doing the now-lost second section's advice.

Any guidance on how to overcome this?

Thank you so much.

I was forced to erase my PC because it was infected with malware. I saved my Tbird profile to my HDD before erasing. I pasted the saved profile to %Appdata% >Thunderbird, copying 1,777 items. When I brought up Tbird, I got the Account Setup window, so I don't think the profile was actually there. What did I do wrong?

What to move my talktalk emails to my Hotmail, as my talktalk email is closing down very soon ,both signed in ok on Thunderbird ,but emails will not copy when dragging to Hotmail,if i try right click on an email in Thunderbird move to or copy to i see there is a small pad lock icon on both email address,any help please....

Every now and then a folder flag will change to the drafts flag/icon, it seems to be a random occurrence which can happen to any sub-folder. Up until the most recent Thunderbird upgrade I had a working extension called FolderFlags which allowed me to go into the Folder properties and change it back but that extension no longer works with the latest version of Thunderbird and there is no alternative extension. How do I change the flag back to it showing as an ordinary sub-folder in my Inbox instead of Drafts? As an interim measure I've created a new sub-folder and copied the emails from the old into the new but that's not ideal at all. I hope somebody will create an updated extension but has anyone any other suggestions please?

Had this problem suddenly crop up since the update of one of my accounts not sending mail due to timeouts. I've not changed any passwords or settings since I had it working last. The message is the "Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) [my workplace's SMTP server] timed out. Try again." one, and it's preventing me from sending any emails.

Specifics:

• It's one account (my work one: work runs an Outlook/Microsoft mail server).
• My personal account (gmail) sends fine. Both accounts recieve email fine too, so this is just one direction on one account.

Things I've tried:

• Switching my Firewall off makes no difference, so it's not a firewall problem
• It's not that the emails I'm trying to send are too large, one word test emails also don't send
• Extending the timeout time by 3x doesn't help

I also opened a second computer not yet running the latest version - the account worked fine. Then applied the upgrade and that broke things in exactly the same way as described above. So I'm pretty sure this is an issue caused by the upgrade in some way. Not sure if other people with Outlook servers are having the same problem or if there's any workaround available but would appreciate advice.

Hello, I opened up Thunderbird and it said it was downloading 28 messages but they don't show up in my inbox. I went online to log in to my email that way and the messages were downloaded. I check the trash in Thunderbird, they aren't there. The time stamp stops at 9:23am this morning and picks up with one message at 1:05 that I received after the 28 went missing. Any ideas where they might have gone? Thank you so much!
