Hi,

Old (and production) version : dovecot --version 2.1.9

New version : dovecot --version 2.3.16 (7e2e900c1a)

Exactly same configuration, for shared configuration : namespace { list = children location = maildir:%%h/Maildir:INDEX=~/Maildir/shared/%%u prefix = shared/%%u/ separator = / subscriptions = yes type = shared }

But : On Old version, with my imap client (Thunderbird), I see : <account> / shared / <shared account> / INBOX <account> / shared / <shared account> / all the others folders

On new version, I see : <account> / shared / <shared account> / all the others folders

But not <account> / shared / <shared account> / INBOX

I debug it, and seem to be OK : doveadm acl debug -u <account> shared/<shared account>/INBOX doveadm(<account>): Info: Mailbox 'INBOX' is in namespace 'shared/<shared account>/' doveadm(<account>): Info: Mailbox path: /home/dovecotmail/<shared account>/Maildir doveadm(<account>): Info: All message flags are shared across users in mailbox doveadm(<account>): Info: User <account> has rights: lookup read write write-seen write-deleted insert post expunge create delete admin doveadm(<account>): Info: Mailbox found from dovecot-acl-list doveadm(<account>): Info: User <shared account> found from ACL shared dict doveadm(<account>): Info: Mailbox shared/<shared account>/INBOX is visible in LIST

And in debug log : Oct 23 12:35:01 imap(<account>)<18244><IrkoZALP4eRQfHif>: Debug: Mailbox shared/<shared account>: Rotated transaction log /home/dovecotmail/<account>/Maildir/shared/<shared account>/.INBOX/dovecot.index.log (seq=982, reset=no) Oct 23 12:35:01 imap(<account>)<18244><IrkoZALP4eRQfHif>: Debug: Mailbox shared/<shared account>: Recreated /home/dovecotmail/<account>/Maildir/shared/<shared account>/.INBOX/dovecot.index (file_seq=982) because: .log file format version 1.2 is too old

Debug is ok for me ?

Any idea ?

Thanks

You need to add a setting for this behavior,
