this one is pulling my hair out!
We have a subdomain setup email.xxx.com It has the MX/TXT and SRV settings for O365 all set correctly (and tested successfully). The issue is coming because we need to point this to another set of NS servers, I can’t get this to work through Cloudflare.
When I try to create NS for this subdomain I get an error message stating this “Non NS records already exist with this host code 81055”.
So, question is, am I able to create this set of records in Cloudflare, with the other records required to ensure the email works successfully in O365 or is it not possible?
