Managing Microsoft Exchange environments

The key aspects of managing a Microsoft Exchange environment with One Identity Manager include the mapping of mailboxes, email users, email contacts, and the mail-enabled distribution group.

The system information for the Microsoft Exchange structure is loaded into the One Identity Manager database during data synchronization. It is not possible to customize this system information in One Identity Manager due to the complex dependencies and far reaching effects of changes.

Architecture overview

In One Identity Manager, the following servers play a role in managing Microsoft Exchange:

  • Microsoft Exchange server

    The Microsoft Exchange server against which the Microsoft Exchange objects are synchronized. The synchronization server connects to this server in order to access the Microsoft Exchange objects.

  • Synchronization server

    The synchronization server for synchronizing data between One Identity Manager and Microsoft Exchange. The One Identity Manager Service with the Microsoft Exchange connector is installed on this server. The synchronization server connects to the Microsoft Exchange server.

The One Identity Manager Microsoft Exchange connector uses Windows PowerShell to communicate with the Microsoft Exchange server.

One Identity Manager users for managing Microsoft Exchange

The following users are used for setting up and administration of a Microsoft Exchange system.

Table 1: Users
User Tasks
Target system administrators

Target system administrators must be assigned to the Target systems | Administrators application role.

Users with this application role:

  • Administer application roles for individual target system types.

  • Specify the target system manager.

  • Set up other application roles for target system managers if required.

  • Specify which application roles for target system managers are mutually exclusive.

  • Authorize other employees to be target system administrators.

  • Do not assume any administrative tasks within the target system.

Target system managers

Target system managers must be assigned to the Target systems | Exchange application role or a child application role.

Users with this application role:

  • Assume administrative tasks for the target system.

  • Create, change, or delete target system objects like user accounts or groups.

  • Edit password policies for the target system.

  • Can add employees who have an other identity than the Primary identity.

  • Configure synchronization in the Synchronization Editor and define the mapping for comparing target systems and One Identity Manager.

  • Edit the synchronization's target system types and outstanding objects.

  • Authorize other employees within their area of responsibility as target system managers and create child application roles if required.

One Identity Manager administrators
  • Create customized permissions groups for application roles for role-based login to administration tools in the Designer as required.

  • Create system users and permissions groups for non role-based login to administration tools in the Designer as required.

  • Enable or disable additional configuration parameters in the Designer as required.

  • Create custom processes in the Designer as required.

  • Create and configure schedules as required.

  • Create and configure password policies as required.

Setting up Microsoft Exchange synchronization

One Identity Manager supports synchronization with

  • Microsoft Exchange 2010 Service Pack 3 or later

  • Microsoft Exchange 2013 with Cumulative Update 23

  • Microsoft Exchange 2016

  • Microsoft Exchange 2019 with Cumulative Update 1

One Identity Manager is responsible for synchronizing data between the Microsoft Exchange database and the One Identity Manager Service. Synchronization prerequisites are:

  • Synchronization of the Active Directory system is carried out regularly.
  • The Active Directory forest is declared in One Identity Manager.
  • Explicit Active Directory domain trusts are declared in One Identity Manager
  • Implicit two-way trusts between domains in an Active Directory forest are declared in One Identity Manager
  • User account with password and domain controller on the Microsoft Exchange client domain are entered to create linked mailboxes within a Active Directory resource forest topology

To load Microsoft Exchange objects into the One Identity Manager database for the first time

  1. Prepare a user account with sufficient permissions for synchronization.
  2. One Identity Manager parts for managing Microsoft Exchange systems are available if the TargetSystem | ADS | Exchange2000 configuration parameter is set.

    • In the Designer, check if the configuration parameter is set. Otherwise, set the configuration parameter and compile the database.

    • Other configuration parameters are installed when the module is installed. Check the configuration parameters and modify them as necessary to suit your requirements.
  3. Install and configure a synchronization server and declare the server as a Job server in One Identity Manager.
  4. Check whether the domain trusts are entered correctly.
  5. Enter the data for creating linked mailboxes within a resource forest.
  6. Create a synchronization project with the Synchronization Editor.
