To set up initial synchronization project for Exchange Online

1. Start the Launchpad and log in on the One Identity Manager database.

   NOTE: If synchronization is run by an application server, connect the database through the application server.

2. Select the Target system type Exchange Online entry and click Start.

   This starts the Synchronization Editor's project wizard.

3. On the wizard's start page, click Next.

4. On the System access page, specify how One Identity Manager can access the target system.

   • If access is possible from the workstation on which you started the Synchronization Editor, do not change any settings.

   • If access is not possible from the workstation on which you started the Synchronization Editor, you can set up a remote connection.

     Enable the Connect using remote connection server option and select the server to be used for the connection under Job server.

5. On the Deployment/organization domain page, you record the following information.

   • Deployment: Select the cloud deployment where your Exchange Online environment will run. Your options include Microsoft 365 global service and Microsoft 365 GCC High.

   • Organization domain: Enter the Azure Active Directory name of the domain.

     Example:

     <yourorganization>.onmicrosoft.com

6. On the Connection parameters page, enter the login data for connecting to Exchange Online.

   • If you want to authenticate with a specific user account, enter the following information.

     • User name: Enter the fully qualified name (FQDN) of the user account for logging in.

       Example:

       <user>@<domain.com>

       sync.user@<yourorganization>.onmicrosoft.com

     • Password: Enter the pass word of the user account.

   • If you want to authenticate with a self-signed certificate (the app-only authentication), enter the following information.

     • Application ID: Application ID created when the application is registered for Exchange Online PowerShell in the Azure Active Directory tenant.

     • Certificate thumbprint: Self-signed certificate thumbprint.

   Click to test the connection parameters.

   NOTE:

   • Use the Add set button to enter more connection parameters. These connection parameters are queried cyclically by the Exchange Online connector when queries are sent to Exchange Online. By using multiple connection sets, it takes longer to reach the throttling limit.

     For more detailed information about throttling limits in Exchange Online, see the Microsoft documentation.

   • If you authenticate with a self-signed certificate, you must ensure that each connection set has its own application registration. The same certificate cannot be used more than once for different application registrations.

   • Click Check all sets to perform a one-off test of all the connection parameter sets.

7. On the last page of the system connection wizard, click Finish to return to the project wizard.

8. On the One Identity Manager Connection tab, test the data for connecting to the One Identity Manager database. The data is loaded from the connected database. Reenter the password.

   NOTE:

   • If you use an unencrypted One Identity Manager database and have not yet saved any synchronization projects to the database, you need to enter all connection data again.

   • This page is not shown if a synchronization project already exists.

9. The wizard loads the target system schema. This may take a few minutes depending on the type of target system access and the size of the target system.

10. On the Restrict target system access page, specify how system access should work. You have the following options: Read-only access to target system.

    Table 5: Specify target system access

    Option	Meaning
    	Specifies that a synchronization workflow is only to be set up for the initial loading of the target system into the One Identity Manager database. The synchronization workflow has the following characteristics: Synchronization is in the direction of One Identity Manager. Processing methods in the synchronization steps are only defined for synchronization in the direction of One Identity Manager.
    Read/write access to target system. Provisioning available.	Specifies whether a provisioning workflow is set up in addition to the synchronization workflow for the initial loading of the target system. The provisioning workflow displays the following characteristics: Synchronization is in the direction of the Target system. Processing methods are only defined in the synchronization steps for synchronization in the direction of the Target system. Synchronization steps are only created for such schema classes whose schema types have write access.

11. On the Synchronization server page, select the synchronization server to run the synchronization.

    If the synchronization server is not declared as a Job server for this target system in the One Identity Manager database yet, you can add a new Job server.

    1. Click to add a new Job server.

    2. Enter a name for the Job server and the full server name conforming to DNS syntax.

       TIP: You can also implement an existing Job server as the synchronization server for this target system.

       • To select a Job server, click .

       This automatically assigns the server function matching this Job server.

    3. Click OK.

       The synchronization server is declared as Job server for the target system in the One Identity Manager database.

    4. NOTE: After you save the synchronization project, ensure that this server is set up as a synchronization server.

12. To close the project wizard, click Finish.

    This creates and allocates a default schedule for regular synchronization. Enable the schedule for regular synchronization.

    This sets up, saves and immediately activates the synchronization project.

    NOTE:

    • If enabled, a consistency check is carried out. If errors occur, a message appears. You can decide whether the synchronization project can remain activated or not.

      Check the errors before you use the synchronization project. To do this, in the General view on the Synchronization Editor‘s start page, click Verify project.

    • If you do not want the synchronization project to be activated immediately, disable the Activate and save the new synchronization project automatically option. In this case, save the synchronization project manually before closing the Synchronization Editor.

    • The connection data for the target system is saved in a variable set and can be modified in the Synchronization Editor in the Configuration > Variables category.
