When you run Exchange Server Setup together with the /PrepareSchema to update the schema for an existing Exchange hybrid environment, you receive the following error message:
A hybrid deployment with Office 365 has been detected. Please ensure that you are running setup with the /TenantOrganizationConfig switch. To use the TenantOrganizationConfig switch you must first connect to your Exchange Online tenant via PowerShell and execute the following command: "Get-OrganizationConfig | Export-Clixml -Path MyTenantOrganizationConfig.XML". Once the XML file has been generated, run setup with the TenantOrganizationConfig switch as follows "/TenantOrganizationConfig MyTenantOrganizationConfig.XML".
If you continue to see this this message then it indicates that either the XML file specified is corrupt, or you are attempting to upgrade your on-premises Exchange installation to a build that isn't compatible with the Exchange version of your Office 365 tenant. Your Office 365 tenant must be upgraded to a compatible version of Exchange before upgrading your on-premises Exchange installation.
When you follow the instructions in the error message to generate the XML file, and then you run Setup /PrepareSchema together with the /TenantOrganizationConfig switch, you receive the following error message:
The parameter 'TenantOrganizationConfig' is not valid for current operation 'PrepareSchema'.Setup checks failed: Invalid command line arguments.
The /PrepareSchema switch is valid only for schema operations. The /TenantOrganizationConfig switch is used with the /PrepareAD switch.
To resolve this issue, run Setup together with the /PrepareAD and /TenantOrganizationConfig switches. For example, run the following command:
Note In this scenario, schema extension is performed implicitly by running the /PrepareAD switch. Therefore, to complete these steps, you must have Schema Admin rights to perform the schema changes in addition to the rights that are necessary to perform the /PrepareAD steps.
