I am using kmail with oauth2 office 365. It has been working fine until recently.
Now the handler goes offline, crashes and will not send mail.
It has started working doing a aconadictl restart and/or logging in to office 365 again. Now the email just doesn’t want to leave the outbox.
What can I try?
I am on kubuntu, all kdepim versions is 4:23.08.5-0ubuntu5.
I really want to keep on using kmail.
I stopped kontakt. Restarted akonadi again and the mail was sent. But I can’t have such a unreliable mail client. I feel that this is an opportunity to make the software better.
If you had a crash, can you locate it with coredumpctl and extract the backtrace into a bug report on bugs.kde.org?
The crash reporter in kubuntu says that the dump has to little information.
What is your distro?
You should be able to install debug symbols, that will make the trace useful.
We have steps for different distros at Guidelines and HOWTOs/Debugging/How to create useful crash reports - KDE Community Wiki
He mentioned it’s Kubuntu. According to the kdepim version number, it should be Kubuntu 24.04.
Ubuntu should provide debuginfod for automatically loading symbol files. Perhaps it just needs to be enabled with set debuginfod enabled on inside a newly created ~/.gdbinit file?
I really don’t understand how debuginfod works, myabe I don’t. But the examples is starting the application from gdb. In this particular case it is a forked off process that is crashing (I assume since the UI isn’t affected). Can gdb follow forks to create a good crash report?
I think I got it. You find the pid of the crashing program, attach to it.
I just hope I attached to the correct one. Trial and error 
Would this be a good backtrace?
