You are locked out of the domain after you start Outlook 2007

Symptoms
Consider the following scenario in a domain environment:
  • A domain account and a Microsoft Office 365 account have the same user principal name (UPN).
  • The passwords for the domain account and for the Office 365 account differ from each other.
  • Active Directory Federation Services (AD FS) is not used in the domain.
  • The account lockout value is something other than the default value.
  • You log on to the domain from a computer that's running Windows 7, and then you start Office Outlook 2007.
  • You make some WinHTTP requests to Office 365. For example, you open a shared calendar.
  • There are no on-premises Exchange resources
In this scenario, you are locked out of the domain.
