Hello, I didn't get the way of dealing with annotations. It is some specific parameter in the imapd.conf file. But I didn't understand the syntax so I can set it for sharedseen. SETANNOTATION "mailbox" \ "/vendor/cmu/cyrus-imapd/sharedseen" ("value.shared" "true") http://irbs.net/internet/info-cyrus/0809/0090.html Otherwise setting the command as cyrdadm: mboxcfg mailboxname sharedseen true wouldn't work. Is that correct?
