After the migration is complete and you have confirmed that the mail flow is working properly and that there is no missing information, you must guide the point of contact (POC) to revert the nameservers back to the original ones in their domain registrar and to complete the domain verification in the Microsoft 365 Admin Center.
NOTE: If the customer keeps the nameservers with SkyKick (on the Amazon Web Services), the customer won’t be able to manage their DNS themselves and will need to contact us, which is why you must guide them to revert the nameservers back to their original ones.
Below, you will find an example on how to revert the nameservers in GoDaddy but note that the POC might use a different domain registrar and the steps to update the nameservers will also be different.
- From the Microsoft 365 Admin, complete the domain verification step by going to Settings > Domains and click on the domain.
- Click the Continue setup option.
- Select the Add your own DNS records option and click the Continue button.
- You’ll be provided a list of DNS records (MX, CNAME, TXT) to update in the domain registrar (in this case, GoDaddy).
- Log into GoDaddy.
- Locate the domain and click the DNS button.
- Click the Change button in the Nameservers section.
- Select the I’ll use GoDaddy nameservers (recommended) option and click the Save button.
- Confirm the change.
- In the Records section, remove the existing CNAME, MX and TXT and add the new ones from Microsoft 365.
- Go back to Microsoft 365 Admin, click the Continue button. It may take a few minutes for the DNS changes to get propagated. Once the domain setup is complete, click the Done button.
