Nino_Bilic there is an issue with Hybrid orgs and running the /PrepareAllDomains or /PrepareDomain requirement after installing the May 2022 SU. We run a Hybrid org, Exchange 2016 at CU23 and updated with the May 2022 SU. When running the required Setup.exe /IAcceptExchangeServerLicenseTerms_DiagnosticDataON /PrepareAllDomains from C:\Program Files\Microsoft\Exchange Server\V15\Bin, the Prerequisite Analysis fails with the error "A hybrid deployment with Office 365 has been detected. Please ensure that you are running setup with the
/TenantOrganizationConfig switch". It also fails with the same error if the /PrepareDomain switch is used. However, the /TenantOrganizationConfig switch is not compatible with /PrepareDomain or /PrepareAllDomains and is only compatible with /PrepareAD. If we attempt to use /TenantOrganizationConfig in combination with /PrepareDomain or /PrepareAllDomains it generates the error "The parameter 'tenantorganizationconfig' is not valid for current operation 'PrepareDomain'. Setup checks failed: Invalid command line arguments."
As the prerequisite analysis fails on all attempts, we cannot complete this requirement as documented and thus cannot patch the CVE as required. How do we solve this issue?
