Autodiscover DNS Entry

Hi

I have moved a clients emails from their local SBS Exchange server to hosted exchange

Everything is working ok apart from when it tries to download the offline address book, I have been told it's something to do with the local DNS setting for autodiscovery.

When I ping 'autodiscover.domain.co.uk' it ping the hosted exchange so I am unsure?

On the local DNS server (SBS) I have a DNS entry for autodiscover.domain.co.uk that points to their local server address of 192.168.1.2

When we run the Outlook Test AutoConfiguration / Log Tab it states that it's trying to download from https://remote.domain.co.uk/.....

Can anyone help :-)

thanks

is it not working internally or externally or both? if it doesn't work on their site you will need to change their local DNS to point to the hosted exchange server's external IP (or internal if there is a tunnel). You also need to make sure there is an SSL Cert that is setup with the domain on the hosted exchange server.

When I try remotely the outlook test config shows failed within the log tab. At the end of the log its show srv redirect and its successful.  However the address book doesn't download straight away.

I can confirm there is an ssl cert on the hosted exchange.

So on the local dns do I just add a A host for autodiscover to point to cas.messageexchange.com servers ip?

I am using giacom for my emails

thanks

yes you will need to change the current autodiscover record to point to the new server's IP address.

You have removed the Exchange server from the internal server?
If not, then the clients will use that first. You need to either remove Exchange, or change the URL

Simon they have another company with a different domain name that still uses the internal exchange. I will be moving this to the cloud within the next month

There is nothing you can do about it then.
When machines are members of a domain, they will always query the domain for Autodiscover information. If it exists then they will use it.
You could try removing all evidence of the old domain from the server, which includes mail disabling the user accounts that have been moved to the cloud.
