Hi Cahrles
i do use gmail and here it does show also my sent email related to the thread, i dont think i tweaked it in anyway.
here is an example of that as an image
where you can see that my sent emails (xebar) are in the same thread as the other ones related to the orgzy thread.
i do have offline imap working and my indexing and have tried running them manually and then starting mu4e and i still dont get the sent email in each thread only emails from other people.
as you can see my emails related to the thread are not there
would appreciate any help in trying to debug this
best
z.
