how to change the CNAME with DNS server

I have been asked to do the following from the company that is hosting our email exchage servers.

To my understanding you are using as your Active Directory domain. In this case, you will also need to update your internal DNS servers.

All that’s required a change of a CNAME record.

You will need to change:

autodiscover CNAME


autodiscover CNAME

Please advise

If you open your DNS console and expand Forward Lookup Zones do you see

And if you do, can you see an existing record called autodiscover?

I see the autodiscover but the type is listed as a HOST A.

Great okay.

Delete that one, then right click and add a new Alias (CNAME) record. The name will be autodiscover again, then you pop the name they've given into the target box (I forget the label I'm afraid, the lower of the two boxes).
