Extensions for supporting Exchange Hybrid environments

NOTE: The following modules must be installed to support Exchange Hybrid:

  • Active Directory Module

  • Microsoft Exchange Module

  • Azure Active Directory Module

  • Exchange Online Module

  • Exchange Hybrid Module

NOTE: You cannot move mailboxes between local Microsoft Exchange and Exchange Online with One Identity Manager. Microsoft offers migration scenarios for moving mailboxes. For more information, see your Microsoft documentation.

One Identity Manager support creating, editing, and deleting of remote mailboxes in Exchange Hybrid. Remote mailboxes are mailboxes that are declared in the local Microsoft Exchange environment but were added in an Exchange Online environment.

There are the following different types of remote mailboxes:

  • Remote mailbox

  • Remote room mailbox

  • Remote equipment mailbox

  • Remote shared mailbox

These mailboxes can be added to distribution lists or be given sending limits in the local Microsoft Exchange environment, for example.

The synchronization server running the Microsoft Exchange connector is responsible for synchronizing remote mailboxes. The other target system involved (Active Directory, Microsoft Exchange, Azure Active Directory, and Exchange Online) must be synchronized in order to access remote mailboxes.

Advice for synchronizing remote mailboxes

Take the following into account when synchronizing Exchange Hybrid remote mailboxes:

  • The mapping for remote mailboxes is part of the Microsoft Exchange project template. Remote mailboxes are synchronized using the Microsoft Exchange connector.

  • If an Exchange Hybrid environment already exists but there is no Exchange Hybrid module installed, a warning appears when you synchronize. Install the Exchange Hybrid module and create a new synchronization project.

  • The following order is recommended for synchronizing the target systems.

    1. Azure Active Directory

    2. Local Active Directory

      Synchronization can be simultaneous with Azure Active Directory synchronization.

    3. Exchange Online

    4. Local Microsoft Exchange

      It is better to synchronize after synchronizing Exchange Online.

  • In One Identity Manager, the connection must be defined between the local Microsoft Exchange organization (EX0Organization) and the corresponding Azure Active Directory tenant (AADOrganization).

    This connection is normally created automatically when the synchronization project is created for local Microsoft Exchange. This assumes that Azure Active Directory was already loaded in to the One Identity Manager at the time. You can establish this link manually at any time.

    To declare the Azure Active Directory tenant in a Microsoft Exchange organization

    1. In the Manager, select the Active Directory > Exchange system administration category.

    2. Select the organization from the result list.

    3. Select the Change main data task.

    4. On the Hybrid configuration tab, under Azure Active Directory tenant, select the Azure Active Directory tenant to which your local Microsoft Exchange is connected.

    5. Save the changes.

Advice for migrating mailboxes

You cannot move mailboxes between local One Identity Manager and Microsoft Exchange with Exchange Online. Microsoft offers migration scenarios for moving mailboxes. For more information, see your Microsoft documentation.

Synchronizing Microsoft Exchange after moving a mailbox from local Exchange Online to Microsoft Exchange in One Identity Manager results in:

  • A remote mailbox being created

  • The local mailbox being marked as outstanding.

After successful migration, delete outstanding mailboxes in One Identity Manager.

  1. Check whether the mailbox was migrated and whether the Active Directory user account is connected with the local mailbox and a remote mailbox.

    Migrated mailboxes are displayed in the Manager in the Active Directory > Troubleshooting > Mailboxes migrated to Exchange Online category.

    • Select the mailbox and switch to the Active Directory user account overview. Here you can see whether the user account is connected with a local mailbox and a remote mailbox.

  2. Delete the outstanding mailbox.

If you apply an account definition to local mailboxes, create a new account definition for remote mailboxes.

  • If the mailbox account definition currently in use, expects an account definition for Active Directory user accounts, enter this account definition as prerequisite for the remote mailbox account definition.

    IMPORTANT: The remote mailbox account definition may not be distributed automatically to everybody. Otherwise One Identity Manager creates new remote mailboxes.

Example of exchanging account definitions for migrated mailboxes

The following is an example explaining how you can replace account definitions with migrated mailboxes

NOTE: The workflows described here are only for orientation. Always take your customized workflows into account while replacing.

You always required a custom migration scenario if the account definitions are requested through the IT Shop.

Example:

Local mailboxes are managed through an account definition. This account definition requires an account definition for Active Directory user accounts.

The account definition is directly assigned to identities.

After migration, remote mailboxes are also managed through account definitions.

  1. Create an account definition for remote mailboxes. Enter the Active Directory user account's account definition as prerequisite.

  2. After migrating a local mailbox:

    1. Make sure that the remote mailbox exists in One Identity Manager and is linked to the Active Directory user account.

    2. In One Identity Manager, delete the outstanding local mailbox.

    3. Assign the account definition for remote mailboxes to the identity.

    4. Remove the account definition for local mailboxes from the identity.

Example:

Local mailboxes are managed through an account definition. This account definition requires an account definition for Active Directory user accounts.

The account definition is inherited by the identities through it's department relation.

After migration, remote mailboxes are also managed through account definitions.

  1. Create a parallel structure to the department and assign the account definition for local mailboxes to this parallel structure.

    The purpose of this parallel structure is to retain the local mailboxes' account definition assignment to an identity until the mailbox has been successfully migrated.

    • Configure a dynamic role for this parallel structure, to include all identities that:

      • Belong to the department and do not have a remote mailbox.

        or

      • Belong to the department and own a remote mailbox and an outstanding local mailbox.

  2. After completing DBQueue Processor processing, you can remove the account definition for local mailboxes from the department.

  3. Create an account definition for remote mailboxes. Enter the Active Directory user account's account definition as prerequisite.

  4. Create another parallel structure and assign the account definition for remote mailboxes to it..

    The purpose of this parallel structure is to assign the remote mailboxes' account definition to identities after mailbox migration and to retain the assignment of the required account definition for Active Directory.

    • Configure a dynamic role for this parallel structure, to include all identities that:

      • Belong to the department and own a remote mailbox.

  5. Delete the outstanding mailbox after migrating the local mailbox successfully.

  6. After migrating all the department's local mailboxes, you can:

    1. Assign a department to the remote mailboxes' account definition.

    2. Remove the parallel structure.
