Since the last update to version 146.00, under the folder Archives, both the sub folders for 2024 and 2025 have changed to Drafts and I cannot change them back to show the year folder (2024 & 2025). None of my other yearly Archived sub-folders are affected from 2016 - 2023.

Under Properties, both show their respective year correctly - i.e. imap://xxxxxx1%40sky.com@imap.mail.yahoo.com/Archive/2024 and; imap://xxxxxx1%40sky.com@imap.mail.yahoo.com/Archive/2025

I attach screenshots showing the issue and any help would be appreciated.

In essence, after trying various ways of trying to sort the above out, it would be helpfull Mozilla if under the Folder Properties box, I could just change the name back from Drafts to the appropriate year. However, in the folder box when selecting the Name line, it won't allow you to alter the folder name. This would seem the simple solution to any alteration of Folders by being allowed to rename them back to the original name.

I have uninstalled and reinstalled Thunderbird twice, n - the second time deleting the Mozilla folder under C:\users and then rebooting This happened whilst I was using Thunderbird. I have used Thunderbird for years without problems I have run a virus scan with Malwarebytes, but no problmes showed up. All folders are still vixible on my iPhone

I am about to try reinstalling again. I don't want to have to change email clients.

Any help much appreciated.. Thank you Joan Kemp

i get from tthunderbird " the certificate for imap.supanet.com is not from a trusted source " but can i overide this as i do trust the source please reply on [edited from public forum] 6@supanet.com

Hi. I have created 2 subfolders in "Drafts", which ALSO turned into draft folders:

• The folder icons switched from the standard folder icon to the "Drafts" icon.
• The right-click context menu is reduced (just like for other special folders), e.g. the "delete" command is missing.

So how can I delete this misbehaving folder now ?

I doublechecked in my account manager and via config editor that the subfolder are NOT used as DRAFTS folder for any of my (POP3/maildir) accounts.

Thank you so much.

Since update to version 145.0 I cannot send messages, when sending I get this message "Sending of the message failed. An error occurred while sending mail. The mail server responded: <*******@shaw.ca> sender rejected AUP#POL. Please verify that your email address is correct in your account settings and try again". Nothing has changed with account settings. Same problem on another machine that updated to 145.0. Any ideas what is broken?

Eclipse webmail being withdrawn but always used Thunderbird to open it on PC. Archive from 2007 saved in Local Folders in Thunderbird on PC. Once Eclipse is gone can I still open old e-mails in local folders ?

Good day all,

I had some old emails stored in a Local folder.

While I could see the the header information shows up in the view panel (from address, subject, date, etc), I could NOT see the contents of the email (the preview window is entirely blank), and attempting to copy the email failed.

I completed the 1st Repair detailed in this link as it seemed to be the exact same issue: https://support.mozilla.org/en-US/questions/1515421

When It was completed, all except four of the old emails disappeared. The four remaining files can be opened & read (so the repair worked on those four).

Examining the Inbox mbox file as explained in Repair #2 (link above) showed only the data for the four remaining files.

My question - does anyone know of a way to 1) restore the emails that vanished?, and 2) after restoring the emails that vanished, how to be able to read them?

I have a back-up of the entire profile that was made before the repair - so I can pull specific files from that back-up and "start over" if need be.

Thx!

Random emails are coming in looking like this: (private, USPS, etc.) Why?

Since a recent TB update in August, the program now downloads previously-deleted messages from Gmail. TB downloads from the In folder (OKI), but also current messages that I sent to Trash folder (not OK).

Example: 50 new messages appear in the Gmail In folder. I delete 30 messages from the In folder, and they correctly move to the Trash folder, leaving 20 in the In folder.

I next launch TB on my Win10 PC and press F5 to begin the download. Until recently, I would get the remaining 20 messages and ONLY the 20. Now, TB downloads all 50, as if 30 were never deleted.

                                                       NOTE:  I changed no settings at either end.'

If I go into the Trash folder before downloading and delete today's trash, those messages are totally gone and won't download. But this was never necessary a few weeks ago.

If any reader had and fixed this annoying problem, please tell me how you did it.

Aiming to reduce memory used by my email. I have both Sent and Sent Mail folders. My preference would be to eliminate the duplication that takes place with the two. I understand that I can not unsubscribe from Sent Mail. Could Sent content be reduced to the items that are NOT in Sent Mail? Alternatives? My Sent folder contains more older files which I would like to retain but do not want to "try" something that MIGHT eliminate them. I am on a Mac23 with Latest Sonoma. Thunderbird on Gmail.

My inbox messages that are incoming are showing the following message and no data. This has happened for several days. It comes from both internal and external contacts and I know the emails are not spam/junk. How do I fix it so I get the messages. It is this same code on all days and all the emails with this message. I do get some of my other emails so not sure how it is decided which this is happening to but I am missing out on several that I need due to this issue. Thanks for your assistance!

Hello TBird fans,

I wonder when ThunderBird native client for Android (currently named "K-9") will evolve to a point when internal calendar syncing will work properly, eliminating the need to import google calendars into desktop Tbird ? Is it possible to estimate that time now, or it's better to search for alternative solution(s) ?

I will need an Android synced calendar app soon, I would prefer ThunderBird, since I've been using it for at least a decade, and I'm not even satisfied but became enthusiast also. Best email client ever made IMHO. It would be very convenient to use TBird's integrated calendar.

I've searched the forums for "android calendar sync", but didn't find corresponding info, just this archived thread is closest to my question (particularly the 3. question of it) : https://support.mozilla.org/en-US/questions/1436077

I'm not willing to use google calendar, since I don't want unstoppable notifications and ads when my events are due in time.

Thanks, Peter ;-)

Message filters not working after transfer to new windows device. (Apologies for long report below). Problem is similar to that reported and still unsolved here: https://support.mozilla.org/en-US/questions/1391209

All old messages automatically accessed under IMAP protocol sit within correct email folder on new device.

Message filters rules successfully located on old device, copied and placed in corresponding windows folder on new device. Email folder structure looks identical on both devices.

New messages sit in inbox on new device, without being filtered. Instead error messages appear, repeatedly.

"The folder 'xxxx' could not be found, so filter(s) associated with this folder will be disabled. Verify that the folder exists, and that filters point to a valid destination folder.

The folder 'yyyy' could not be found, so filter(s) associated with this folder will be disabled. Verify that the folder exists, and that filters point to a valid destination folder.

If same new messages are accessed on old device, they later appear in correct folder on new device, and no longer sit in inbox

How to make email folder structure on new device visible to filter rules there ? This is necessary for filtered email to work successfully on new device, without requiring old device to be operational - it will be taken out of service in near future.

I am trying to consolidate emails using the Thunderbird identity feature. I have a single email account call it acct1@yahoo.com. I have three other email addresses that get forwarded to Yahoo, call them acct2@pobox.com, acct3@pobox.com, and acct4@hostmonster.com. I can send emails to all of these accounts. In Thunderbird yahoo is the default identity and the other three are alternate identities. The outgoing server settings are all identical (see screenshot). I can send emails using the acct1 and acct2 identities, but not the other two. This is puzzling because acct2 and acct3 are both forwarded identically.

The error message I get is not very helpful: Sending of the message failed. An error occurred while sending mail. The mail server responded: Request failed; Mailbox unavailable. Please verify that your email address is correct in your account settings and try again.

Thunderbird is so slow, especially when deleting emails. This has been happening for a month or so. It got better last week, it seemed normal, but it's back to being infuriatingly slow to delete messages. My workflow is very disrupted. Any solutions? I need my time back!

I use Thunderbird 128.2.0esr (64-bit) to read mail from the Outlook server; these are the folder mappings:

imap://<email>@outlook.office365.com/INBOX imap://<email>@outlook.office365.com/Sent imap://<email>@outlook.office365.com/Drafts imap://<email>@outlook.office365.com/Trash

I used to also be able to read the Junk Email folder from the Ourlook server the same way, but the folder disappeared from my Thunderbird a couple of months ago. I tried re-adding it as a sub-folder, which is how I created it in the first place, but it won't appear on the list.

I'm not sure what else to do here. I don't know where the Thunderbird directories are stored locally any more, I'm using Ubintu 24.04.
