In a single tenant with multiple domains, it is a challenge within the organization to allow administration of mailboxes. A Global Administrator, for example, can make any change to any of the domains. A user with password only capabilities can change passwords to any user in any domain within the client. Since we can make custom views for specific domains, it would be very beneficial if there was an option to assign a "custom view" to users that have administrative privileges. This way a user in domain "A" can only mange passwords and mailboxes in domain "A" and isn't capable of editing or even viewing anyone else in the tenant. This is especially useful when a (parent) company acquires a bunch of (child) companies and wish to consolidate into Office 365. Each organization has their way of managing their mail environment. The change to Office 365 is a big change within itself, and changing how the system is managed is another set of obstacles to overcome. With a particular custom "view" mapped to specific users or a group of users would address this issue. Thank you for your time.
