Moving mail from public folders to personal inbox

When I try to move a mail from a public folder to my inbox it just gets copied instead of moved. My permissions on the public folder are “owner”. How to move mails?

Is there no way to fix this?

Hi,

do you use Outlook? Right click the mail - Move will move the mail.

No, of course not :-) this is why I posted it in Kopano DeskApp :-)
