|Working with Groups and Departments / About the Built-In “Everyone” Group|
Vocera also creates an Everyone Everywhere group when you complete your installation or upgrade.
Each Everyone group is a member of Everyone Everywhere.
Like an Everyone group, Vocera automatically maintains membership in Everyone Everywhere, but you can specify all other properties for it. Unlike the Everyone group, there is only one Everyone Everywhere group, and it is associated with the Global site.
The Everyone Everywhere group determines the default set of permissions for users across all sites.
