A company has an on-premise Exchange Server 2007 SP2 environment. Client computers run
Microsoft Outlook 2010. The company plans to migrate to a cloud-based Microsoft Exchange Server
2010 SP1 service. You need to recommend a solution for ensuring that Outlook locates the cloudbased servers when users check calendar availability information. What should you recommend?
A.
Add a CNAME record.
B.
Add an MX record.
C.
Synchronize the AD DS directory from the on-premise environment.
D.
Synchronize the AD DS directory from the cloud-based environment.
Explanation:
What you need to do is add a CNAME record with the host value of Autodiscover. So the full record
would be autodiscover.domain.com. Once you have that CNAME you need to point it to
autodiscover.outlook.com. The way you know this works is to do an NSLOOKUP:
nslookup autodiscover.domain.com
You should see something like this:
Server: dns.corp.domain.com
Address: 192.168.1.10
Non-authoritative answer:
Name: autodiscover.outlook.com
Address: 65.55.94.54
