We have these "old mail" and "nstmp" folders that will not delete.

right click on Empty Trash doesn't work, need to delete individual emails.

Windows 11

I have been using Thunderbird for over 5 years. I am presently using version 128.11.1esr and I update it often. Many e-mails have been put into an "Archive" folder but I just noticed that all of the items put there are now gone. The "Archive" folder is empty. The account that this is attached to is AOL, xxx@verizon.net.

Are there any thoughts on how this could have happened? I am hoping I can get the items back.

Thanks for your thoughts, Steve H.

Can I find all my emails again please please help me!!!

I don't even know how to explain what happened - I just know this is my booked jobs for the rest of the 2025!! The folders are "greyed out" and it says "0kb"

I see the emails on webmail though - but not my own answer emails and not in folders (= very messy)

I really really don't know what to do!

THANK YOU SO MUCH in advance

why just today is all my incoming emails coming to trasha nd not my in box in Thunderbird worked fine in the morning but i am not getting any mail in my in box it is all going to trash

I converted to Thunderbird 128,11.1esr in May 2025. My address book did not migrate to the newer version and I don't have the old one. Also, I don't know how to return to the previous version of Thunderbird.

When I delete an email message, they do not go to Trash, they just disappear. I have used TB for several years but this started happening just recently. I can right click on a message and Send To to Trash, or drag and drop, and both those and work. I have went through all the settings I can find, and don't see any obvious problems. I did find a "fix" from 2023 that involved deleting the Smart Mailboxes folder and restarting TB but that that didn't help.

i am trying to copy my Thunderbird to a new laptop. I am asked to enter my password but I did not keep a note of this. How can I find this password to complete getting Thunderbird on my new Laptop. I am 87 tears old and not very technical minded. please make any answers simple. Thank you

Recently, my SENT file has not been keeping the email I send. Has anyone else had this problem? Can anyone suggest how or why this has started happening?

I count on being able to look and see that I have sent or replied.

Thanks for any help, Jerry

Monday: Computer #1 lost all e-mail use and old correspondence. Computer #2 had e-mail service. Left Computer #2 up with program (Tebra) until account needed verification which needed e-mail to get the code (could not). Now we have both computers which cannot work. what can we do to get our e-mail back???

Hello. I am trying to send emails from Thunderbird 128/140 for Linux via Exchange Server 2010 via SMTP. SMTP authorization is performed using Kerberos/GSSAPI, without connection encryption (Connection security: Note). An error occurs when sending: "Sending of the message failed. The Kerberos/GSSAPI ticket was not accepted by the Outgoing server (SMTP) test.domain.name. Please check that you are logged in to the kerberos/GSSAPI realm" Error console: mailnews.smtp: NS_ERROR_FAILURE: Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) [nsIMailAuthModule.getNextToken]

IMAP with Kerberos/GSSAPI is works correctly. Evolution works correctly with the same SMTP settings (it logs in and sends emails).

Hi there,

I've recently had a problem with a couple of client PCs where their Thunderbird profile folder has grown to fill the entire hard drive. In both cases, the relevant account folder in the profile's ImapMail dir had grown to over 300Gb. This account takes up 45Gb on the server (where I'm running Dovecot with maildir storage). In another case on both PCs, an 18Gb account had grown to over 90Gb.

Both client PCs are running up-to-date Thunderbird (139.0.2 64bit), one under Windows 10 and one under Windows 11. Both had auto-compact set, with the minimum saving reduced to 100Mb. Both problematic accounts are shared accounts that use a deeply-nested folder structure. In both cases, I was forced to delete and then recreate the these accounts in Thunderbird.

I'm an experienced sysadmin who is also running the mail server, so I am able to provide any extra info needed. Additionally, I accept that these are large email accounts; I'm in the process of setting up an email archive system for the client using Piler. I have read many other reports of outsize Thunderbird data folders; these are usually referring to less than 20Gb. The problems we're having seem to be an order of magnitude larger!

Thanks in advance, P.

No matter what I do all I get is this: Login to server imap.gmail.com with username smyn1118 failed. and: Unable to log in to server. Probably wrong configuration, user name or password. Any ideas? ....... Sam

Contacts with only an Organization and no first and last name will not synchronize to iCloud. I have to add the company name in the last name field to get it to sync. Running version 139.0.2 (64-bit).

Thunderbird 138/139, Windows 11 Pro 23H2. While composing a message, after a few lines the app freezes. Both the compose window and the main TB window freeze. Only opening the Windows Task manager allows me to close them. This did not happen with earlier versions.

If I save the message every few seconds while composing I can get most of the message back and continue after restarting TB. This behavior is the same in both the normal and troubleshooting TB modes. I can't even find a crash log to send to Mozilla.

Where shall I look next?

Thank you!

We've not changed any settings and today the name and email address of the sender of an email no longer appear when replying. It's always appeared prior to today.
