I am trying my best to get Live@edu working before converting to office365 (well the email side) to work so that students can have their own school email addresses.
I have proved i own my domain by speaking to the ISP and asking them to create the TXT file Students and insert the random characters on my domain so i now have students.domain.co.uk. I have also asked them to create 2 CNAME entries webmail.students and mail.students to point to outlook.com/students.domain.co.uk. I also have the TXT file on my internal DNS servers. Does that need to be there?
This works from the outside world but i cannot get it to work inside the domain. How can i get round this? I have tried adding a CNAME (webmail.students) to my forward lookup zone to domain.co.uk in my local internal domain servers at work, but no joy.
Also, i can send emails from the administrator account to my work email but i cannot send any emails to students.domain.co.uk. Do i need to speak to my ISP again and ask them to create a MX record for students.domain.co.uk as i don't have a record for this.
Actually the DNS host would have to support MX on subdomains before 365 gets involved unless your using 365 to do the DNS. I looked at that but did not want MS to be looking after DNS records for my entire domain preferred either my own DNS servers or my registrars
So i should i register students.domain.co.uk with the ISP. This seems to be getting messy. I thought i could just have mail.domain.co.uk as my main MX record pointing to my exchange server then have a MX pointing to students.domain.co.uk as my office365 domain. Everything so fair is working but just need to see if my ISP will allow this change. So far they (ISP) have been very helpful and told me if things will work or not.
