ISSUE: The running command stopped because the preference variable "ErrorActionPreference" or common parameter is set to Stop: You can't use the domain because it's not an accepted domain for your organization

Overview

The Onboarding Progress screen might display the following error:

Execute_HYBRID_MoveMailboxToO365: An error occurred during Exchange Online Powershell | The running command stopped because the preference variable "ErrorActionPreference" or common parameter is set to Stop: You can't use the domain because it's not an accepted domain for your organization. [ProcessResult]

Solution

The Mailbox has an SMTP Address that isn't a accepted domain in Office365.

To fix this either:

1. make that domain an accepted one in Office365
2. remove that SMTP address from the mailbox.

• After completion do an AAD Sync
•  Contact the customer so they can run this Powershell command in EOL PowerShell
