"HCW8039 The hybrid Send connector must only contain the single address space" error when you run Hybrid Configuration wizard

PROBLEM
When you run the Hybrid Configuration wizard, you receive the following error message:
HCW8039 The hybrid Send connector must only contain the single address space '{0}
CAUSE
This issue occurs if the Send connector that's created by the Hybrid Configuration wizard has additional namespaces added to it.
SOLUTION
To resolve this issue, follow these steps:
  1. Open the Exchange Management Shell.
  2. Run the following command:
    Get-SendConnector -name "Outbound to Office 365" 
  3. In the output, examine the value of the AddressSpace parameter. You should see either "*" or "contoso.mail.onmicrosoft.com;1."
  4. If you see any addresses other than "*" or "contoso.mail.onmicrosoft.com;1," remove them. To do this, run the following command:
    Set-SendConnector -name "Outbound to Office 365 "smtp:contoso.mail.onmicrosoft.com;1" 
  5. Run the Hybrid Configuration wizard again.
