I am trying to move my DNS service over from Office365 to AWS Route 53. AWS was where the domain was purchased but due to the ease (at that point at least) the DNS entries were setup at Offce 365. I'm now trying to move them over to route 53 as we're launching some web services from that domain. I've tried following https://docs.microsoft.com/en-us/microsoft-365/admin/dns/create-dns-records-at-aws?view=o365-worldwide but this seems to be if it's coming from the start. My domain is setup in full at AWS but
> dig -t ns mydoamin.com
;; ANSWER SECTION:
mydoamin.com. 21599 IN NS ns1.bdm.microsoftonline.com.
mydoamin.com. 21599 IN NS ns2.bdm.microsoftonline.com.
mydoamin.com. 21599 IN NS ns3.bdm.microsoftonline.com.
mydoamin.com. 21599 IN NS ns4.bdm.microsoftonline.com.
How do I delete these. Office 365 under the admin center -> settings -> Domain --> mydomain.com I only get the option to copy. I've also tried the 'remove domain' but that seems to be the delete. Any help much appreciated. I have looked at other stackoverflow/server fault questions but none of them that I can see tell me how to get rid of the NS entries. Probably something obvious.
