Hi,

We currently have OWA, Outlook Anywhere and ActiveSync published on our TMG server but we have to move it off on to an alternate solution.

As we already have UAG in place for DirectAccess and to provide portal access to other applications on a seperate domain we would like to move these Exchange services across to a new trunk.

I have a few questions:

1) Is this just a question of importing the cert from the listener on TMG on to the UAG box and creating a new HTTPS trunk using that cert?

2) Once the trunk is configured can we then publish the 3 services before making any changes to our external DNS thus leaving TMG working and in place?

3) Have I understood it correctly that once the services are published, we make the change to our external DNS and end users will just start to come across seamlessly once the DNS their device is using updates to the new IP address?

4) Would I be able to test this (at least OWA) by using the UAG trunk IP address in the URL before making the change to the external DNS records or is it a cross fingers excercise?

Thanks in advance for any a
