Imap account keeps downloading greyed out deleted messages. Checked server and they are not shown there. Repeated deletions and emptying trash does not solve issue, neither does compacting. Deletions are set to go to the imap trash folder.

For the last couple weeks my new unread emails have not been displaying in the list or the preview pane. This is only happening for my IMAP account and not the 2 Gmail accounts (which are also IMAP). I see the "new message" count but no new messages are displaying. I see TB connecting, logging in and opening my IMAP inbox without errors. IMAP is configure according to my Network Solutions email provider (Port 993, SSL/TLS, normal password). After closing and opening TB several times sometimes the messages load. Sometimes once a new email is received that and other new messages will display.

The uploaded image shows my inbox with a new message count of 47, quick filter set to unread and no messages displaying.

Not sure if this is related but TB also is having occasional issues copying messages to the sent folder after sending.

Been using Thunderbird for Android for many months for the email accounts I have with my ISP [optonline.net]. Several days ago sending of emails began failing. Error messages appearing in my Android Notifications say, "Failed to send some messages" "Sender refused". This is happening on all 4 of the devices my wife and I use. 2 phones and 2 tablets. Optimum is blaming Thunderbird. Thunderbird is still working fine on my Windows computer. It seems that all info regarding turning on Troubleshoot mode is referring to the Windows version as I can't find the "Help" menu item in the Android version anywhere. I have reconfigured the accounts in Thunderbird multiple times. The setup of SMTP always seems to end clean with a message of "Settings saved". It seems to me that Thunderbird is getting some error code from my ISPs mail server and I am hoping to have some more info to share with their tech support. The version if Thunderbird for Mobile we are on now is 9. I noticed that version 9 was just released on 5/5/2025. Not sure when exactly version 9 was pulled down to my devices. My phone is Android version 10. My tablet is Android version 14. Both are having the same exact issue.

Hello, All of a sudden when turning Thunderbird on, I have found that all messages in my Inbox have gone ( except a few for last day or two). Looking around Thunderbird I have found all Inbox emails have bee dumped into my Trash folder! Please help - how can I get emails back where they belong and get Thunderbird back into working order? Very grateful for any help' Thank you, kindest regards Brian Benger PS where will I get your reply if my email not working??

Hello,

My Windows version of Thunderbird is missing my global folders ("Saved"). It appears in my Android version of Thunderbird.

Attached are screenshots of the available folders for the email account's webmail app, Thunderbird Windows & Android.

Everything was working fine till we lost power yesterday. I used my iPhone as a Hot Spot to get emails, but couldn't send them. Power back and our server, but still not able to send emails. I have tried setting up a new security key and deleted my email account and rebuilt it with no change. Very frustrating! I need to be able to send emails out. Soon! Attached are the messages I get. Nothing works. Window 11 Pro

What does this mean, Unable to open the summary file for Sent . Perhaps there was an error on disk, or the full path is too long. This just appeared. How do I get my sent emails back

After a reboot of my computer (Win11) I cannot open any locally stored Emails in Thunderbird (138.0.1) any more.

These Emails can be seen in the message list in their folders but do not open any more in preview nor can I open them. Also trying to move them to another folder does not work, nor can I forward them by right-clicking and select "Forward message".

On the hard disk the data is still in the profile folders and I can open them with a text editor.

I already tried copying the profile to another folder and open it with a new profile. The same result.

A re-installation also did not solve the problem.

Many thanks for any suggestion how to solve this issue

Well. Now the situation gets more confused. T'Bird: 128.10.1esr (64-bit) Just did an update . . . and all the file folders in my left pane disappeared. NO THANK YOU! Why? Where did they go? How to get them back?

And then, should they reappear perhaps the initial issue can also be addressed and solved: Subfolders were greyed-out and in italics; when attempting to drag an incoming message into one of those folders it is refused . . . locked out . . . rejected. So, what's all that about? How to solve that?

Thank you.

I've not changed any settings but now thunderbird keeps downloading the same messages from my earthlink.net account, like 10 times for each message.

Hello,

interesting behavior with a CalDaV calendar entry/date.

Scenario: Create a calendar-entry (date) with an alarm-setting (1h before...). Wait until the new entry is synced to the CalDAV server, in my case a Nextcloud. Close TB. Got to the Nextcloud calendar, or to and other client with that CalDAV Calendar, and remove the alarm, I do frequently in case the date paste... Start TB. After sync of the calendar, TB is telling you, that the date was changed at the server and asked "how to handle the detected conflict" (see screenshot). But 1. it isn't a conflict, just a normal change, which should change the local, "old" date 2. acting on the conflict resolution by pressing the button "Skip changes, load new" (Änderungen verwerfen und neu laden), I'm expecting to get the server version exchanging the local, old one... It does not: The local version will stay with the alarm. These date will not sync to server until TB is restarted. The alarm is now back on the server.

If the alarm is removed at the server (or on another client) while TB is running, the alarm is removed locally as "normal" change by synchronization...

I guess it is a bug!?

I'm using TB Version 128.4.3esr; build-id: 20241108210256 on Windows 11 (64bit). But this is also with TB under Linux (ubuntu, mint)

Hello, I've installed Thunderbolt and added my Outlook account. However, none of the folders I created in Outlook have been copied over. Only the standard built-in folders e.g inbox, junk, sent etc were setup in Thunderbolt with all the mail from the other folders in the inbox. This is not very helpful.

How do I set up the Thunderbolt account so that the folders (and contents) are matched with the folders (and contents) in Outlook? Thanks

Thunderbird does correctly mark emails I choose as spam spam. Problem is, TB fails to move these marked-as-spam emails to the selected spam folder. I've searched for cures here but nothing helps. Now what Mozilla??? See attached pics...

W11 rig. TB updated today to 138.0.1 (64bit). All message on inbox show up ok, but all messages on the local folders are blank.

But I can access all email in all folder from my W10 rig which is running 128.9.1 esr so I know the msr files etc are not corrupted. This is only happening on the w11 rig

Repair approach makes no difference when tried through the w11 rig. Have rebooted w11 computer, reloaded TB several times. No change.

Need suggestions to get the W11 rig working with all messages. Thanks

I can send mail via thunderbird but now will not get it from earthlink server? tried restarting app, computer and router, no help. My mail is in my web mail but not thunderbird
