Office 365

We're trying to get Office 365 working but can't get the damn thing to work when running the Microsoft "confirm that you own mydomain.co.uk". Problem is it can take up to 72 hours to populate the DNS servers so every time we change the settings we have to wait 3 days before we find it's wrong!

Currently we have our own server but want to test a trial of Office 365 and currently we have

Left field Type Pri Right field
remote.mydomain.co.uk. a 123.456.789.0
mail.mydomain.co.uk mx 100 123.456.789.0

obviously domain name and IP address altered

and this works fine for remote access to Outlook Web Access and Microsoft Exchange respectively.

What we can't get to work is using what Microsoft advise.......

Left field Type Pri Right field
mydomain.co.uk. MX ?? ms***********.msv1.invalid.outlook.com

Has anyone been able to get this to work?

It seems fine to me, you need the top level domain (i.e. mydomain.co.uk vs mail.mydomain.co.uk), you need the value displayed on the verify domain page (this changes for if you delete the domain and try to verify it anew), and the priority should be say 200 in your case.

There might be some limitations applied by the domain registrar however, so it's always best to check how the added entry looks "from outside". With 1h TTL it should take a lot less than 3 days to see the changes, but its always best to verify them from 2-3 locations to make sure they have propagated over the internet.

You can always test with a TXT record as well, which is the safest option. You even have the option to create a CNAME if all else fails.
