Creating a subdomain in O365
Hi, Is there any way of creating a subdomain in O365 with an already existing domain? Example: webshop.contorso.com where contorso.com is the main domain controlled by the NS pointers by Microsoft....
Hi headmaster,
Is advised to use a DNS managed externally to have other options that are not available on DNS managed by Office 365, you can read more here https://docs.microsoft.com/en-us/office365/admin/setup/domains-faq?view=o365-worldwide

Thanks for answer.
But to change a domain to an external DNS provider is always a risky business with a risk for down-periods for both homepage, mail, SharePoint and Teams. I would not say that it is an easy thing to fix for a medium size company with important communication flow.

Hi headmaster,
If you prepare all DNS records on the destination DNS when you change the name servers on your registrar of your domain, you will not have any downtime.
