I'm running into problems preparing the schema in my AD. We currently have Exchange 2010 SP3 installed onsite with our Office365 tenant space. We have been upgraded to V15 in Office365. I followed the instructions and connected via powershell to our tenant space and generated the MyTenantOrganizationConfig.XML file. Running the exhange setup with /TenantOrganizationConfig switch comes back with not supported with /PrepareSchema. Runing setup with just the /TenantOrganizationConfig doesn't work either. Both URL links below don't work, the first one just takes you to a general Exchange page.

FAILED
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 | E
xport-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. For more information, see:http://go.microsoft.com/fwlink/?LinkId=262888
