Hi,

I have one new arrived mail in Kmail that is marked as unread, can't be deleted or moved to trash and can't be moved to another folder.

When I try to move it, I get this error message:

"Unable to retrieve item from resource: [LRCONFLICT] Resource akonadi_maildir_resource_0 tries to modify item 41649 () (in collection 18) with dirty payload, aborting STORE."

Is there a way I can get rid of this mail or the notice that it is unread?

The topic is already a bit older, but I would like to take it up again since I currently have the same case.

How can I delete such e-mails?

@JuergenGr: Did you found a solution?

Edit 2020-03-27: With following explanation I was able to find and delete the missing RID. https://forum.kde.org/viewtopic.php?t=138233&start=45
