IMAP, CalDav, and CardDav are an open set of rules for synchronizing your emails, contacts, calendars, and tasks with mobile or desktop
Collaboration Suite creates mobile profiles which you can download, configure, and sync your mobile devices.
Android OS natively (without the help of external apps) supports IMAP for managing email; however, CalDAV and CardDAV require installation of
apps like OpenSync. Mac and iOS have provisions for working with CalDAV and cardDAV; hence, you do not need any Mac or iOS app to work with them.
This section explains how to export profiles.
To import these profiles to your mobile devices, you may want to look at below help articles:
