I'm trying to set some folder properties in kmail2, and I get popups saying the following: "Admin@eregion.de: Fehler beim Schreiben einiger Annotationen für "buildservice" auf dem IMAP-Server. SetAnnotation failed, server replied: A000490 NO Permission denied". Is this from akonadis imap-like engine thing or from the actual imap server? Reproducible: Always Steps to Reproduce: 1. try to set folder properties Actual Results: error message like described above Expected Results: properties are properly stored the folders also have lost their "identity" settings.
Updating the imap server to a recent verion solved this.
