Steps to reproduce:

I'm using microsoft 365 with IMAP. I have a saved search called "Combined" that shows all emails from two folders: INBOX and Sent Items. This allows me to see the emails I send along with what I receive in the same thread.

Test setup:

  1. Send myself an email from my gmail to my microsoft 365 work email address.
  2. Reply from my work email address. (The reply shows up at the bottom of the thread, as expected.)
  3. Collapse the thread.
  4. Un-collapse the thread. (Now the sent message shows up twice at the same indent level.)
  5. Close and re-open thunderbird or go to a different folder and then back. (Now the sent message only shows up once, as expected.)

The problem (double messages displayed) also happens for replies that I receive in threads. Again, closing/re-opening thunderbird or moving to a different folder and back again make the doubles go away.

So I realized something that may be others debug this. Even though the double message shows up in the message view pane, it is not counted in the numbers in the folder pane. So the message pane may show and unready message double, but there is no number 1 next to the folder name.

Karmeron, are you still seeing this?

Yes, still happening on 115.4.1

Another oddity is that if I click the green unread icon on the duplicated email (well the 2nd one, I'm not sure which is the original since they arrive at the same time and are identical), it will mark both as read. But if I click it again, it only marks the first one as unread.

This is now fixed in 115.9.0.

By the way, how do I mark this bug as resolved? Or do I not have the permission to do that?
