You have an Exchange Server 2010 organization.

You need to prevent users from changing their password by using Outlook Web App (OWA).

What should you do?

A.
Create a Group Policy Object.

B.
Create an Outlook Web App Mailbox policy.

C.
Modify the authentication settings of the OWA virtual directory.

D.
Modify the authentication settings of the IISADMPWD virtual directory.

Explanation:
This question is confusing as two answers are correct. If you wish to disable the changing of passwords through OWA for all domain users, then you would use the following command:

Set-OwaVirtualDirectory -Identity <OWAVirtualDirectoryName> -ChangePasswordEnabled $false

However, if you wish to prevent certain users from changing their passwords through OWA, then you use the Segmentation tab of the OWA mailbox policy in the EMC. Or, alternatively, you could use the following command:

New-OWAMailboxPolicy -Name ‘OWA Mailbox Policy Name’ | Set-OWAMailboxPolicy -ChangePasswordEnabled $false

I have gone for the former answer as it does not specify that it should only be configured for certain individual users.
