Getting Started

The Zimbra Admin Plus module does not require any initialization procedure in order to be functional.

All Zimbra Admin Plus operations can be performed by any global admin through the Zimbra Admin Plusistration Zimlet.

What is Zimbra Admin Plus

Zimbra Admin Plus is one of the modules of Zimbra Suite Plus.

It allows all Global Administrators of your Zimbra server to grant "Delegated Administrator" rights to other users and to manage such rights in an easy and effective way.

Global Admins and Delegated Admins

A "Global Admin" is a system operator which has full administration rights on the Zimbra server, whose tasks include:

  • Keeping the server healthy and fully functional.
  • Managing software updates and upgrades.
  • Handling domain/user provisioning and the correlated range of operations.

A "Delegated Admin" (also called "Junior Admin") is either a system operator or a "non-IT" user with very limited administration rights on one or more domains. Such rights are tailored in such a way that the Delegated Admin can neither view data for which he lacks authorization for nor change any system setting. The Delegated Admin's job is usually to support the Global Administrator(s) by performing all tasks related to user provisioning.

Delegated Admin Management

Delegated Admin Provisioning

  • Create and manage Delegated Admins, with limited rights on the Zimbra Administration Console.

Quota Management

  • Settings dedicated to better manage your users' quotas and to avoid running out of space.

Domain Limits

  • Set per-domain limits for a customized experience and effective multitenancy.

Zimbra Administration as a Delegated Admin

  • The bread and butter of Zimbra Administration for Delegated Admins


Delegated Admin Log Browsing

  • Browse your logs from the Zimbra Admin Plusistration Zimlet with an advanced filtering system.
