Groups are used in Zoho One to simplify user management. Groups allow you to
provision app access to and to
enforce security policies for multiple users simultaneously. Besides this, if you have added Zoho Mail, you will be able to create email aliases for groups and use them for broadcasting messages.
Two types of Groups are available in Zoho One:
Collaboration Groups: These are flexible, ad-hoc groups that can be used to meet any custom, niche requirements. For example, you can create a group with all of your organization's managers, allowing them to share and collaborate on their documents, or you can create a group with all of your organization's on-premise staff and impose an IP-restrictive Security Policy on that group, or you can create group email aliases for team-specific broadcasts or newsletters.
Departments: Some apps use a special type of group called Department, where a user will not be allowed to join more than one Department. For example, Zoho People and Zoho Connect use the Department attribute to emulate the hierarchical structure of an organization. Departments in Zoho One can serve as a single point of management for all the app-specific Departments. Adding a user to a Department in Zoho One will be reflected across all the relevant apps.
