Hi,

today Thunderbird doesnt send nor discharge emails from gmail. I've seen that yesterday (december 10) it was an update. I dont know it the problem it's related or not, but the program doesnt work, it seems that it tries to connect with server but it cant. If I send an email from Gmail page it works.

Thanks for your help miquel arderiu

I just installed the latest Thunderbird 146.0 Win 11.

Configured my server data and Spam settings, etc. Mail coming in and going out OK.

Now I see some messages in the Spam filter that are not Spam. So I click on "Not Spam" button, and the message goes into my Inbox. Great. But after 3-4 seconds, the message is thrown back into the Spam box. I've told it 10 times "Not Spam" and each time it gets moved to the Inbox. Then 3-4 sec later it gets thrown back to the Spam box.

What am I doing wrong? Am I missing a setting?

Hi, I have thunderbird connected to a number of client corporate Office 365 systems (5 in total). The teams option works fine for 4 of them and is quite usable for chat but one of them responds that the browser is an unsupported version. I use Ubuntu 24.04 and have thunderbird and firefox installed from deb files (and the repos) so both are the current/release versions and overall everything works well so I don't believe there is a systemic issue. All connections to the clients' exchange systems are through the owl plugin. With the one client, as soon as you try to connect to their teams site, the 'Hmmm, your browser isn't supported' page comes up. As I manage that client's office platform, I know I've not made any changes to the back-end settings nor have I done so or had to do so on any of my other clients platforms so I don't think there is anything unusual about the Office 365 side (but am willing to be proved wrong). If I try logging in to the problematic teams site using firefox it works perfectly so I don't believe it is firefox being an issue. I have deleted and re-added the account. Has anyone else seen this and got it sorted, and if so how please? Many thanks, Scott...

I am getting frustrated that I keep getting multiple folders with the same name. When I save my emails to a local drive I use ALL MAIL to save and retrieve. Now I don't even have the ALL MAIL folder! Vern

An elderly friend uses Thunderbird on her laptop, and up until recently it has been fine. Then it just sits there and doesn’t show any new emails, just kind of frozen. She can send emails but not receive them.. Previously another friend had downloaded BT software to act as an alternate to access her @btinternet.com emails…. Strangely she hadn’t received any emails for a few days…. I found that her emails were being auto forwarded to an unknown email. I disabled that and her emails arrived and were visible on the BT site. I downloaded the thunderbird app to her mobile and attempted to set her account up , with no luck.

Any suggestions. Should I delete the thunderbird stuff on both laptop and phone and re-install?

Thanks

Maybe a red herring: I was in the middle of doing a Documents folder backup when I decided to open Thunderbird for some reason. Got an Unable to Load Profile type of message. And my attempts at a fix seem to just send me further down a rabbit hole. I started out by renaming my profile.ini file, but I really didn't know what the heck I was doing and possibly caused more harm than good. Then I tried to find my profile file/folder itself, using the Thunderbird > Troubleshooting > Profile Folder path and doing an import from inside TBird but that ended up with various problems such as drilling down to the profile folder from within TBird but then when I clicked Select Folder in Thunderbird, that didn't trigger any sort of import.

I also spent a good deal of time trying to find my AppData folder, finally being able to view it (a hidden folder, apparently), and saw several recently-dated profile types of folders, but again, I couldn't manage to "hook up" any of those folder/files from starting inside TBird and selecting Import... I ended up just stuck inside a folder, not triggering any Importing activity.

Finally I found a profile folder (5yed...) at a higher level on my PC than inside that long AppData Roaming Thunderbird path. THIS profile was inside: D:\DOCS\Thunderbird\Profiles

Now THAT folder I managed to get an Import to trigger. But the result was an Error Message telling me to go find my Error Console. Can you please see the attached Error Code display screengrab and tell me there's hope that this was at least the right file but just poor results that I can fix somehow???

The following is my copy/paste of the text I see in the Error Console display that's in my screengrab after trying to import the above 5yed... profile, in case it helps you see it better:

Also attached below are also:

• a screengrab of a set of profiles I found, but when I drilled down to them from within TBird's Import selections and clicked Select Folder, as far as I got was an open folder, or something like that.
• Thunderbird's Troubleshooting Info "Profile Folder" path.
• Message telling me to see the Error Console. The message appeared right after I tried importing the profile that's stated in TBird's Troubleshooting Info "Profile Folder" path.

Here's the copy/paste of the Error Console message display after my try at importing the profile that is in the path that TBird's Troubleshooting Info page "Profile Folder" states (maybe it's the same as my 5yed...profile import try's Error Console display, dunno:

Thanks for any help in getting through this.

Been getting a bunch of this, usually in my TB TRASH folder, I think from the Outlook online server.

The server couldn't retrieve the following message:

Subject: "<Removed for PII>"

From: "Not available" ("Not available")

Sent date: 10/31/2024 2:25:02 PM

The message hasn't been deleted. You might be able to view it using either Outlook or Outlook Web App. You can also contact the sender to find out what the message says.

I have 2 personal email accounts: Outlook and Gmail. My client is Thunderbird. Running Win11 25H2. Far as I know, problem began recently. This is a screenshot of some messages from TBirds TRASH folder.

User's image (In images) Thunderbird just tried to fetch emails. Got a notification that it could not get messages, this time from GMail.

What does this mean? Outlook/Gmail servers or Thunderbird? What do I need to do?

New laptop. Took it to the Geek Squad to move the data from my wife's old computer to new. They had me sign in to Windows on the new machine and perform the setup steps, then took it and the old computer to do the data transfer. The issue is that the returned new computer had my MS profile on it but my wife's mail under that profile.

To try to correct this, I set up my wife's profile on the new laptop and my thought was to export the email from my MS account's TB data to a public folder, turn off TB and sign off my MS profile, sign back on to my wife's MS profile, start TB and import the zip file in the public folder. However, it tells me the folder is too large and I must unzip and import from the extracted folder. Windows Explorer won't let me unzip the file saying it's not a valid zip file. Ideas?

Thanks!

As it turns out, my LOCAL FOLDERS is a sub-file in my account. I have a whole bunch of sub-files within the LOCAL FOLDERS sub-file. When I right click on that file, it does not give me the option to reorganize (re-alphabetize) that sub-file. In other words, I want to reorganize the sub-files of a sub-file. Is this just not an option, or is there a way to do this?

I am able to receive emails with my Spectrum account but unable to send. My SMTP entries are Description Server Name mail.twc.com port 587 Connection security SSL/TLS Authentication normal password When I test the connection it passes and I can see my emails but am unable to send emails and get this message Sending of the message failed. The message could not be sent because connecting to Outgoing server (SMTP) mail.twc.com failed. The server may be unavailable or is refusing SMTP connections. Please verify that your Outgoing server (SMTP) settings are correct and try again. When I look in the Thunderbird settings/privacy and security the only password entry is for IMAP password. Do I have to have and entry for SMTP password or is it the same for both? If I do how do I get an entry there. If any other information is needed please let me know. Thanks

I was away from the computer for a few days until Dec 9. I have now found while I can open the program, it doesn't work correctly. At first, it wouldn't delete emails from the inbox. Now, in addition to not deleting the emails from the inbox, it won't download new emails from my ISP server. I checked the server settings and they appear to be correct. I can send a test email to myself and receive it at my ISP email server, but Thunderbird won't download it. I am using what I believe is the current version of the program (Version 140.6.0esr (64 bit). I am not a computer literate person and don't know what I need to do to fix the problem. Help would be appreciated. Thanks

Hello:

My Windows Thunderbird has become unresponsive, taking forever to connect to my various accounts. I suspect the problem is with my GMail account--which is not my primary account--is causing the problem, but I am unable to un-sync GMail's All Mail folder.

I was able to get into troubleshooting mode, but TB was still unresponsive.

I have copied the profile in question to my Linux machine, with TB V140.4.0esr, to try to repair the profile, but the problem is recurring there as well.

Is there a way to manually edit the profile file(s) to remove the GMail account from Thunderbird?

Any insights would be much appreciated.

Thanks

The sorting of the Recent Destinations menu has changed and is now no longer usable. It is not sorted by most recent or any other obvious order. It now takes me more time to scan through the list to find what I want when it used to be a very useful/quick tool. Anyone else notice this new issue? Thanks!
