You have an Exchange Server 2007 organization.
You recently deployed a server that has Exchange Server 2013 installed.
The Exchange Server organization contains three servers. The servers are configured as shown in the following table.
Server2 contains a mailbox for a user named User1. You move the mailbox of User1 to Server3. After
the move, User1 fails to access his mailbox by using Outlook Web App. Users who have mailboxes on
Server1 and Server2 can access their mailboxes by using Outlook Web Access. You need to ensure
that User1 can access his mailbox from the Internet by using Outlook Web App at
https://mail.contoso.com. The solution must ensure that users who have mailboxes on Server1 and
Server2 can continue to use Outlook Web Access. Which three actions should you perform? (Each
correct answer presents part of the solution. Choose three.)
A.
Export the certificate on Server1 and import the certificate to Server 3.
B.
On all of the Exchange servers, install a new certificate that contains the mail.contoso.com and
legacy.contoso.com names.
C.
Redirect all of the traffic from the Internet for mail.contoso.com to Server3.
D.
On all of the Exchange servers, install a new certificate that contains the Server1.contoso.com,
server2.contoso.com, server3.contoso.com, and legacy.contoso.com names.
E.
Create a host (A) record named legacy.contoso.com that points to Server1.
