# DAV Collection Management

Calendars and addressbooks are maintained as “Collections” within the Cyrus mail store. They appear as mailboxes within the hierarchy, as set by the `calendarprefix:` option in imapd.conf(5) (default is `#calendars`), but should rarely be directly accessed or created using either cyradm(8) or other mailbox-centric tools.

Collections have special attributes, so should be created and maintained either through protocol – i.e. with purpose-built calendar or address book clients – or with the provided web GUI.
