Hi,
One of the steps mentioned during the migration from hotmail to outlook live is this:
Edit the MX record for the domain
- Sign in to the domain management tool at the DNS hosting service for your domain.
- Remove the Hotmail MX record.
- Add an MX Record for <token>.mail.Outlook.com and set it to the highest priority.
Note If you have a third-party MX record, in the Service Management Portal Migration page, click Refresh. Once the removal of the Hotmail MX record is detected, click Skip MX Check.
What must the <token> be in the <token>.mail.Outlook.com namespace?
thanks,
Sk
