This unfortunately still doesn't work.
Microsoft365 needs CNAMES for DKIM records:
All the DKIM Keys have the same format.
In the example below you can replace contoso-com with your domain name and contoso.onmicrosoft.com with your onmicrosoft.com domain.
Host: selector1._domainkey
Value: selector1-contoso-com._domainkey.contoso.onmicrosoft.com
Host: selector2._domainkey
Value: selector2-contoso-com._domainkey.contoso.onmicrosoft.com
Unfortunately BlueOnyx DNS GUI will still not accept adding these records. Fix this field! :-/

Colin
