Same 'Email' address (email address removed for privacy reasons) is already assigned under your tenant, may check the current assignment under admin center

I got this same error message. I checked Exchange Online (Get-Recipient -Filter {EmailAddresses -like "*email-of-the-user*"}), I see no conflicts or duplicates. It is frustrating.
