I've downloaded Thunderbird in office PC and on PC at home. Almost I working in office PC or web mail but when I open Thunderbird at home, all my email lost in web mail and it's happened for such times. Is it a setting problem?! or, if it will be happen if using Android version ?! Thank you for your kindly assist!

I am unable to access my mails on Greenby with Thunderbird and I suspect the password is incorrect. I can read my mails on the Greenby server and know the necessary password but cannot work out how to enter this into Thunderbird! As I am no expert, a simple guide would be most appreciated! Thanks in advance. Roy

Hi. My main email address was accidently removed. All my previous emails are stored locally thanks to Thunderbird IMAP syncing up to now. I'm currently in touch with my ISP in order to restore my email address. This will be done in a few days : I am going to get my email address back, but all the emails on the servers will not be restored. Therefore, when the server is restored, it will be empty.

I fear that when it's done, during the next IMAP sync, my Thunderbird will delete all local emails.

What can I do to prevent that, or circumvent it ? I would like for the local state to be uploaded to the server, not the distant state to delete everything locally.

Used Outlook Mac 2011 for years. It crashed and could not retrieve from Time Machine. Lost everything since 2021. Apple was able to restore my calendar in Calendar app but I'd like to have integrated app and am trying Thunderbird for email. I would love to use it's calendar and contacts. I am nearly 90 and it's hard to learn new tricks but I'm trying. Any help appreciated. Thanks.

I've been using TB for many years, and without warning, when it tries to down load my mail from the Proton mail server, it says it can't find the folder "Inbox". I've tried to "repair" that folder a couple times unsuccessfully. I've restarted the TB program a couple times, but nothing changes. The error shows up on the bottom "instruction line". I've gone through all my settings and find nothing amiss. Not sure where to go from here. -- Just noticed that I had about 80 emails in that Inbox folder that are now missing completely. Normally, I move read emails to there respective folders, and leave important ones in the Inbox for followup. One significant note here, is I'm still using Win 7 premium. So far it hasn't been a problem. Thanks a bunch, Gerald

I've used TB for many years, and keep it up to date. But it suddenly stopped downloads from my email server. Normally everything comes into my Inbox folder and after reading, they are either put into their respective folders or deleted. I had maybe 60 or 70 retained for later attention. (Like due pymnts)

I've tried everything I know, even the mail server connection, but somewhere in the process, I lost everything that was saved in the "Inbox" folder. I got to looking for the profile file, and only found 1 that was recently dated. Not sure if a rebuild would be advisable. Nearly all my (50+) folders show up as normal. Just can't find why the Inbox isn't recognized.

I tried using TB in both safe mode and troubleshoot mode, to no effect. I DO have win 7 Ultimate and hasn't ever been a problem. The error message I get is: "The mail server for account ***** responded with 'mailbox INBOX does not exist!' The name of the folder is "Inbox" as opposed to the capitalized version, but nothing has changed for years, and never been a problem. Go figure??

After _years_ of use and storage, I'm really hurting without it. Any help or suggestions would sure be appreciated. gshantz

i can still see my email folders but these popups appear for each email account in thunderbird (mac osx high sierra) never saw them before so seems something has been compromised? tried to screencap but it's only showing about: url but urls zip by and was able to catch the url a few times earlier but not now.

my accounts are valid this is a new problem just appearing for first time ever

"thunderbird is up to date" for mac os x high sierra

When I highlight multiple messages for deletion; it can take up to a minute to respond; when I am working with gmail or proton, the deletion is immediate. When I am accessing Reagan with browser, the multiple deletions are also immediate. Appears to definitely be a handoff issue. Suggestions? I use Thunderbird on 2 win11 os and 2 linix mint 2.1 machines. I only delete and store to local on one machine (win11) ver/build 23H2: 22631.6199.

In Thunderbird, when reading an eMail, if the Junk or Delete button is clicked on, that eMail gets marked as Junk or Deleted. For either of those selections, the next message immediately gets automatically opened without someone clicking for that to happen.

Our Suggestion is to change the Junk and Delete button features so that only marking an eMail as Junk and deleting it happens, without automatically opening the next eMail. Also, when deleting an open eMail, change it so that deleting it is all that happens, without automatically opening the next eMail after deleting one.

Yes, I'm running unsupported Win 7

And yes, I could not find anything in the "help" system that related.

I maintain a Hotmail account and copy traffic to my local system. Upon reboot Thunderbird shows some files from 2024 and no local folders where I stored all my re-directed traffic.

I've run some system / disk checks and no obvious problems.

Any thoughts besides upgrading to current OS etc? Is there a Thunderbird backup solution to move files away from the active drive to protect them?

I read the instructions on moving my profile to a new computer. The hitch is that on my current, Windows 10 computer, I’m apparently using a 32-bit version of Thunderbird. I only discovered this when I updated it (through Help) and saw that it updated to a December, 2024, 32-bit release. The transfer instructions state that there may be a problem if I try to use a Thunderbird profile from one version to a different version. To prevent that possibility, I either have to update my Windows 10 Thunderbird to the latest, 64-bit release, or specify the 32-bit install on Windows 11. Problem is, I don’t know whether or how I can update Windows 10 computer to latest Thunderbird 64-bit version. Can I? If not, will Windows 11 run a 32-bit release? Suggestions?

I've been using Thunderbird for years but suddenly as of yesterday it's stopped receiving messages. First it told me my password was incorrect. Ever since then when I try to click "Get Messages," it simply has no response at all. Nothing happens. I went into my Thunderbird password settings, and upon seeing that the incoming-message password had for some reason reverted to an old, obsolete password, I corrected it and saved the correct one. I've checked several times and the passwords are correctly saved now. But this did not fix the problem. When I click "Get Messages," nothing happens. My Thunderbird is connected to my Earthlink account, which is working fine. When I go into Earthlink, I am able to send and receive messages as normal. So the problem is not with Earthlink but with Thunderbird.

TB is hung up on my late husband's computer and none of the suggestions made has released it. Current advisors are Windows people and this is an old Mac Mini running OS 10.13. One of your advisors solved a similar problem two years ago and David told me I could open that message by clicking on Robert as question originator. Please email mr at X@perless.com if you have comments or questions.

I posted this earlier and the bot named David is trying to take over with ideas that don’t work. How do we stop it? I also posted from my own email and it tried to stop me.

This is Ellen. I tried restarting Robert's ( my late husband) computer after it crashed and I got the message about Thunderbird's inbox folder not being able to be opened because it is in use by some other operation. It is an old Mac Mini running 10.13 and it says TB is 115.18.0. I don't update it because I don't think his OS can handle anything newer. I just looked and my Mini with an M1 chip (4 y/o?) is running 140. something.

How do I get it to quit whatever it is hung up on? His email is coming in ok on my iPhone.

Robert was a sculptor who made large kinetic works and a lot of his work is still on this computer.

Please help me get out of this mess. I think it has happened before.

I am moving my Thunderbird (32 bit) data from an old Win 7 computer to Linux Mint on a new machine with Thunderbird 64 bit. I have followed all the advice to copy the old computer profile to the profile folder in Mint, but nothing appears in Thunderbird. My pop3 email server has 2-factor authentication; I can set this up and access or send new emails, but I can't import all my old email folders. The old Thunderbird is version 115.18.0 (32 bit) and says it is "up to date on esr update channel" The Mint Thunderbird is 140.0.6 esr (64 bit) and was recently installed with Mint.

As these versions are 32 bit and 64 bit respectively, I don't see how I can make them the same version, as recommended for transferring profiles.

How can I make this work?

I recently moved from Microsoft Outlook email to Apple icloud email. icloud allows you to create an application-specific password, which I did for email. It works; I can login to email on Thunderbird using my (impossible to remember long) password automatically generated by Apple. I switched the Thunderbird server settings to OAuth, but unlike with Outlook, there was no popup saying a restart of Tbird is required. When I quit Tbird and restarted, it did not prompt for a pw, but neither did it get any new messages. (I sent new messages from another email service to verify.)

I also noticed that OAuth2 was not an available option for the outgoing server, as it was with Outlook.

Does OAuth2 not work with icloud email?

There appears to be no way to change the app-specific icloud pw in Apple, but I will take that up with Apple.

Perhaps the workaround is to use the Tbird saved pw feature?
