Expected results:

Mail should be deleted

MacBook Pro
Apple M1 Pro
Ventura 13.4.1

I can't reproduce.
Do you have any add-on? Can you run Thunderbird in troubleshoot mode and see if it still happens?

Only addon Provider for Google Calendar is installed.
Running in troubleshoot mode is fine.
Switching back to normal mode: runs fine

Several times closing the app and restart app: It happens again
I'm sorry but I cannot provide a reproducable "how to"

What is the full version number of what you were using 5 days ago?

(In reply to Dirk from comment #0)

Enabled "delete" in mail list

So this is the delete column, correct?

no action took place. Mail is still listed and available

The message was both in the message list and in the message pane?

If you see this again using 115.0.1 or newer, please immediately check tools > developer > error console for relevant information

Didn't matter. Also sometimes I used delete button in message area but the list wasn't refreshed.

ok

This morning the problem happened again.

• MacBook Pro 14" was in sleep mode for 2 days TB 115.0.1 still running
• Click on trash icon in list didn't work
• choosing right mousekey / delete message worked
• afterwards click on trash icon was successfull
• no immediate entries found in errorlog
  a few minutes later following error messages occurred:
  09:49:06.397

I'm confused by these steps.

After step 2 above, isn't the message already gone?
If you have already deleted the message, how are you able to click the row's trash icon in step 3?

Are you referring to the trash icon in the message row in the message list?

Or are you referring to a toolbar icon outside the message list?

yes, the message is gone

sorry for causing confusion: It was then possible to deleted a different message by clicking the trash icon in the list

(In reply to Kai Engert (:KaiE:) from comment #8)

yes

Or are you referring to a toolbar icon outside the message list?

no

Do you run two email clients in parallel, that are both connected to the same email account?

Is it possible that the issue happens with emails that you have already deleted in a different email client?

(which I guess would be even more confusing, because TB should automatically detect if an email was already deleted on the server)

Was "click on trash icon" the very first action that you performed with Thunderbird after waking up the machine from sleep?

Maybe on the initial click, Thunderbird tried to use a network connection that was stale and gone, because of sleeping?

I'm looking at the code that's referenced in the stack from comment 6.
The interesting place is in about3Pane.js - and it's noteworthy that this file has changed after version 115.0.1 (the version the user was using).

We fail on this line:
// The message for this key can't be found. Perhaps the thread it's in
// has been collapsed? Select the root message in that case.
try {
-> let msgHdr = gFolder.GetMessageHeader(key);

So the code had already concluded that the selected message cannot be found.
The fallback code here attempts to use the selected key to find its header, but that doesn't work either. Does that fallback code make sense?

We already have a commit related to this code here:
https://hg.mozilla.org/releases/comm-esr115/rev/3b0756a31dd45922bf53d538b478ac7fff72050b

It might be useful to wait for Dirk's experiences with 115.1

Possibly related to bug 1840007 ?

yes, but not on the same computer. One client on Mac, one on Android phome, one on Android tablet

(which I guess would be even more confusing, because TB should automatically detect if an email was already deleted on the server)

no, this happens when all the sync staff is done

(In reply to Kai Engert (:KaiE:) from comment #12)

I think so. I wait until the sync with my 5 mail providers is finnished. Then I start with cleaning up mails, deleting those ones from list I don't want to read. Most often, when I place the mouse over the delete icon in list the icon turns to red and the tooltip is shown, but the click is ignored

Maybe on the initial click, Thunderbird tried to use a network connection that was stale and gone, because of sleeping?

I don't know but this behaviour continues even after several syns are done. I first have to use right mouse key / delete message and afterwards I can delete other messages from list by clickung on trash icon in list

I just updated to version 115.1 but the problem continues.
BUT: I just found that this missbehaviour only seems to occur in the "general inbox" showing all the inboxes of 5 providers!
When switching to a specific inbox deleting a mail by clicking on trash icon works!
Switching back to "general inbox" the problem continues.

After upgrading to version 115.1 I rebooted my mac and started Thunderbird. The error console shows the following:

Ah, so you're using the Unified folder mode?

yes

All right, this is important if it never happens in a normal folder.
I still can't reproduce this unfortunately.

This reproduces for me with 117.0b4.

Identify a message and click the trash icon in the unified Inbox message list - nothing happens and nothing in error console. It should work whether the message is selected or not.

Now open the message list for the accounts Inbox, click the trash icon and the message is deleted.
