Try the solution suggested in above mail; it works for me.
Thanks, Marco

Hello,
i have a dovecot server version 2.3.1 under CentOS 6.9 and we're using shared mailboxes with index files shared. With this configuration I can see a lot of error messages like:
Jun 6 13:20:31 mail dovecot: Error: imap(userA@tutech.de)<4513> <onjjWPdtDuLAqG3R>: /export/home/imap/userA@tutech.de/shared /userB@tutech.de/folder/dovecot.index.pvt view is inconsistent
In 10-mail.conf the location setting is:
location = maildir:%%h/Maildir:INDEXPVT=%h/shared/%%u
I thought setting the index files to "not shared" might help to get rid of the errors, so I changed the setting to:
location = maildir:%%h/Maildir:INDEX=%h/shared/%%u:INDEXPVT=%h /shared/%%u
like it's mentioned in the Dovecot wiki. But that doesn't work as I expected, because the 'per-user-seen' flags do not work correctly anymore, i think. If UserA, who has UserB as shared mailbox, changes the seen flags of UserBs INBOX, UserBs seen flags are also changed. The other way, if UserB changes seen flags in his INBOX they are not changed in the shared view of UserA. Is this the supposed way to work or do i have an error in the configuration?
Any help is appreciated.
Thanks, Thomas.
