"HCW8088" error when you run the Hybrid Configuration Wizard

Note The Hybrid Configuration Wizard that's included in the Exchange Management Console in Microsoft Exchange Server 2010 is no longer supported. Therefore, you should no longer use the old Hybrid Configuration Wizard. Instead, use the Office 365 Hybrid Configuration Wizard that's available at http://aka.ms/HybridWizard. For more information, see Office 365 Hybrid Configuration Wizard for Exchange 2010.

PROBLEM

When you run the Hybrid Configuration Wizard, you receive the following error message:

HCW8088 = Tenant user ID not found on service

CAUSE

This can occur if the Office 365 tenant name or user name was incorrectly entered, and if the wizard cannot locate the name in Exchange Online.

SOLUTION

When you enter your Office 365 tenant administrator credentials, use an administrator account such as the initial administrator account whose logon principal name (UPN) uses the contoso.onmicrosoft.com domain. 

Additionally, make sure that you can use your credentials to successfully sign in to Office 365 (https://portal.office.com) before you run the wizard again.
